I picked this bag up last night at the grocery store, after using up the last of the beans I bought in Minneapolis. I brewed my first cup with what has become my go-to starting pourover recipe for medium roasts. It turned out pretty good. It probably helps that I really like dark chocolate, as that was the most prominent flavor I noticed. If the cups consistently turn out like this, I don’t think I need to spend much time tweaking the recipe. As the weather gets cooler, I might want to start thinking about preheating my mug (or switching to an insulated mug) when brewing with water below boiling, so the coffee stays hot a little longer, and I’m not tempted to drink it too quickly.

I noticed that the grocery store also carries beans from Rise Up Coffee Roasters, which is based on the Eastern Shore. I may try one of theirs after I finish my other bag of Zeke’s, which is getting pretty low.

10/12: The same recipe tasted a little bitter this morning. This afternoon, I made another cup using a coarser grind (JX setting 25, or 2.5 rotations), and it was better, but a little bit watery tasting. So, maybe the ideal grind setting is somewhere in between 20 and 25.

10/13: Brewed at grind setting 22 (2 rotations + 6 clicks). Maybe a little better than yesterday’s cup, but still a little bit under-extracted.

10/14: Brewed at grind setting 21 (2 rotations + 3 clicks) and also increased starting water temperature to 99°C. Not perfect yet, but moving in the right direction. Could be that medium roasts need a higher starting temperature with pourover than with immersion? I always preheat the dripper, but I’m sure the water still loses a fair amount of heat while sitting in there percolating. This will be even more noticeable when the air temperature in the room is cooler (e.g. winter).

Epilogue: I eventually figured out a recipe that produces consistently good cups. Synopsis: grind setting 23 (2 rotations + 9 clicks), ratio 1:13 to 1:14, 99°C water to bloom, and 81°C-85°C water to brew. So, my 10/14 hypothesis was wrong — cooler brew water, and a slightly stronger ratio, turned out to be the difference makers.

Vitality Brazil Pourover

lpaulriddle

I’m back home from Minneapolis with a new 12-ounce bag of coffee beans. This was the first time I flew with a bag of beans in my carry-on, and when I unpacked, all of the air had been sucked out of the bag through the little plastic valve, almost like the beans had been vacuum packed. When I opened the bag, air rushed in and everything went back to “normal”. I was worried that this phenomenon might spoil the beans or otherwise negatively affect things, but it did not seem to. It did inspire me to do some reading and learn why the bags have those one-way valves. It’s to let the beans out-gas after roasting, while keeping air out so they stay fresh. I’m learning more every day!

This morning’s cup:

  • Beans: “Brazil Yellow Bourbon” medium roast
    • Roaster: Vitality Roasting (Minneapolis, MN)
    • Roast date: 9/20/2023
  • 18g coffee / 250g water (1:14)
  • JX: 2 rotations (20 on the grind chart / 60 total clicks)
  • Water at 95°C
  • Recipe: A Better 1 Cup V60 Technique (see below)
  1. Preheat V60, pre-moisten filter, add coffee, and tare scale
  2. Make small indentation in center of coffee grounds
  3. 0:00: Pour 55g of water to bloom, then return kettle to base
  4. 0:10 – 0:15: Gently Swirl
  5. 0:45 – 1:00: Pour up to 100g total (40% total weight)
    • Hold kettle for the remainder of the brewing process
  6. 1:10 – 1:20: Pour up to 150g total (60% total weight)
  7. 1:30 – 1:40: Pour up to 200g total (80% total weight)
  8. 1:50 – 2:00: Pour up to 250g total (100% total weight)
  9. 2:00 – 2:05: Gently swirl
  10. Drawdown finished around 2:45

The only brewing note is that (once again) I forgot the initial swirl at step 4. I remembered around the end of step 5, and gave it a half-hearted swirl then. I made sure to level the bed before I started pouring (I’m pretty good with that) and I ended up with a mostly-level bed of spent grounds at the end. I’m not sure how much the swirling actually matters in most cases, but I’ll keep doing it when I remember.

This cup tasted excellent. The beans are very fresh, which I’m sure didn’t hurt. I’d been drinking mediocre conference coffee for the past week, so the bar was admittedly low, but I’d rank this among the better cups I’ve had since I’ve been brewing with the V60.

9/24: Second cup today. Did the swirl at step 4. Overshot the final pour and ended up with 252-253 grams of water. It seemed like the water percolated more slowly than yesterday. The level in the V60 was higher than usual after steps 7 and 8. Drawdown took several seconds longer, finishing at roughly 3:00. Maybe I swirled a little too aggressively? The initial sips tasted slightly thin, but the rest of the cup was very good. If yesterday’s cup was a 10, I’d call this a 9.

9/26: Accidentally ground finer today (setting 18) and also used 17g coffee instead of 18g. Did not like the results. Body was OK, but flavor was bitter.

9/27: Tried a little bit coarser today at grind setting 22, and 18g coffee. The first thing I noticed was that the drawdown was faster, finishing at 2:40-2:45. Definitely a better cup than yesterday’s, with decent body and no bitterness, but room for improvement. I think I’ll keep this grind setting tomorrow and try nudging the water temperature a little closer to boiling. While (with the exception of yesterday) all of the cups I’ve brewed have been good, none of the subsequent cups have been quite as good as the first one, which tells me that bean freshness (and possibly how they are stored) makes a big difference.

9/28: Brewed exactly the same as yesterday, except I nudged the water from 95°C to 97°C. I did not notice any discernible difference from yesterday’s cup. Probably should have gone straight to 99 or boiling. Not sure if I’ll tweak further next time, or just keep brewing it like this.

9/29: Brewed at 99 and grind setting 22 today and the result was bitter and lacked flavor. This is definitely moving in the wrong direction, so I will adjust the temperature back downward next time.

I’m not sure why the first two pourovers I made were really good, but subsequent cups didn’t quite measure up. I wonder if it had something to do with bean freshness. I probably could have gotten it dialed back in, but ended up brewing the rest of the beans in the French press, which worked out pretty well.

Zeke’s Colombia Pourover

lpaulriddle

I went through my last half-pound bag of coffee beans in only 9 days, of which I drank all but two of the cups. So, if we assume that I average 1.5 cups a day, and Cathy has an occasional glass of cold brew, I can expect to use up a pound every three weeks or so. Today, I opened a new 1-pound bag:

  • Beans: “Colombia Sierra Nevada” medium-light roast
    • Roaster: Zeke’s Coffee (Baltimore, MD)
    • Roast date: 9/6/2023
  • 16g to 17g coffee / 250g water (1:15.6 to 1:14.7)
  • JX: 2 rotations (20 on the grind chart / 60 total clicks)
  • Water at 96°C 99°C
  • Recipe: A Better 1 Cup V60 Technique (see below)
  1. Preheat V60, pre-moisten filter, add coffee, and tare scale
  2. Make small indentation in center of coffee grounds
  3. 0:00: Pour 50g to 60g of water to bloom, then return kettle to base
    • 16g coffee → 50-55g water; 17g coffee → 55-60g water
  4. 0:10 – 0:15: Gently Swirl
  5. 0:45 – 1:00: Pour up to 100g total (40% total weight)
    • Hold kettle for the remainder of the brewing process
  6. 1:10 – 1:20: Pour up to 150g total (60% total weight)
  7. 1:30 – 1:40: Pour up to 200g total (80% total weight)
  8. 1:50 – 2:00: Pour up to 250g total (100% total weight)
  9. 2:00 – 2:05: Gently swirl
  10. Drawdown finished around 2:45

The local grocery store has a pretty good selection of Zeke’s Coffee, all in 1-pound bags. I chose this one partly because it’s single-origin, and I’m looking to get a sense for how some of these taste so I can figure out what regions I prefer. Zeke’s labels their roasts on an 8-point scale, and this one is graded 3 out of 8, so I’m calling it medium-light. I used the same recipe as yesterday and the day before, with just a tiny bit hotter water. It seems like it was a good starting point, as the cup was pretty good, although I suspect there’s room for a little bit of improvement. I may try my next cup with boiling water, just to see if it brings out any different flavors.

9/16: Brewed this again with water just under boil (99°C) and I do think I preferred it to yesterday’s. Flavor-wise, it was a little bit reminiscent of my most recent bag of light roast beans, which makes sense, because that was a blend that also included beans from Colombia. It will be several days before I brew this again, but I’ll likely stick with this recipe when I do. I also recently found an interesting AeroPress recipe that I’m curious to check out. The science behind it seems pretty sound, so I’m wondering if it’ll address the issues I’ve been having with weak AeroPress brews.

9/23: Brewed again this afternoon, everything the same as 9/16. It was well extracted, and the flavor was fantastic. If I were to nitpick, it might have been ever so slightly on the strong side, but that’s a good problem to have. I bet I could get away with using a little bit less coffee. Maybe try with 16 grams next time?

9/24: Brewed this evening with 16 grams of coffee and 50 grams initial bloom water. Kept everything else the same. Gets a thumbs up. It was a little bit less strong, but still robust and full-bodied. I might stick with this ratio for a while, unless I’m in the mood to make it stronger (more likely in the morning than the evening 😀).

Interesting note about these beans: after grinding them, there’s less fine “dust” left over in the grinder than with any other of the beans I’ve ground to date. Not sure why that is, or whether it’s considered “good” or “bad”, although I suspect I’ll learn at some point. For now, it’s just an interesting observation.

9/26: For the second time today, I forgot to reset my grind setting after brewing cold brew yesterday, and ended up grinding the beans finer than with my prior cups. I used 16g coffee with a grind setting of either 16 or 18. There was not much difference with the brewing process: very little fine dust left in the grinder, and the V60 drained down at around 2:40. The flavor was definitely different, but not in the way I would have expected. It had a little bit less body and a much more prominent fruity/cherry overtone. While it wasn’t bad, It was decidedly better balanced at the original grind setting of 20, so I’ll definitely be going back to that. Intentional or not, though, It’s always good to learn more about how various tweaks affect the flavor of the coffee.

9/29: Decided to make a larger cup of this “to go” today. I went back to a grind setting of 20, used 20 grams of coffee to 300 grams of water (1:15), and poured in 5 “pulses” of 60g each (vs 50). This worked fine with my size 1 V60 and my 12-ounce Hydro Flask mug, and tasted the same as the numerous 250g cups I’ve brewed. I seem to get pretty consistently good cups out of these beans.

10/2: Have brewed larger cups of this (per 9/29) several times now and they have all been pretty consistently good, but this afternoon’s seemed a little bit better than the others. Same water temperature, same grind size, same ratio, same recipe, etc., except this time I did not swirl the V60 at all. Instead, I rotated it a little bit between each interval, because I noticed that the area closest to where I was holding the kettle looked like it wasn’t getting as much water as the rest. Don’t know if that was the difference maker, but I’m going to try it again next time to see.

10/18: Used up the last of these today. Somehow, I ended up with 29 grams of beans left, which was only enough for two really small cups or one really, really big cup. I opted for the latter, brewing all 29 grams with 435 grams of water for my usual 1:15 ratio. I was initially going to use the French press, but realized that I had already ground the beans too fine, so I stuck with the V60 recipe, and scaled the 5 “pulses” water up to 87 grams each. These beans generate very few “fines”, and the water drains through them quickly, so I had no issues with the dripper overflowing. Other beans might require a larger V60 for this quantity of coffee. The cup was pretty good. I didn’t notice a big difference from the smaller cups I’ve brewed. I would definitely buy these beans again, and probably will at some point.

This cup was just about perfect — full-flavored, well-balanced, and well-extracted. It’s the same recipe that I brewed a few days ago. I added a few extra details here to try to document what I did as closely as possible. I find that I really prefer holding the kettle over returning it to the base after each pour. It makes the whole process seem more smooth and fluid, and I doubt that it makes much difference with regards to the water temperature. It does make me wonder if the volume of water in the kettle has any effect on the resulting brew (the more water in the kettle, the greater its thermal mass, so the longer it will hold its temperature) but I think that’s getting to the point of splitting hairs.

I do wonder why all of my AeroPress brews lately have been weak. Everything I read says it’s because the coffee is ground too coarse, the water temperature is too low, the steep time is too short, etc., but I’ve tried adjusting all of those, and the brew is still weak. I’m not sure what I’m doing wrong. I know it wouldn’t be weak if I brewed it at 1:10, but I feel like I shouldn’t have to — this evening’s pourover was fantastic at 1:15, and my French press cups are good at 1:13 to 1:14. To add to the confusion, it wasn’t too long ago that I was consistently brewing good cups in the AeroPress at 1:14, with different beans that are long gone now. I haven’t been able to replicate that success with any of my other beans. If I have to brew at 1:10, then I don’t see the point of using the AeroPress when I can get the same results with pourover using less coffee. I expect I’ll eventually sort this out, but in the meantime, it sure is vexing.

Fun with pourover

lpaulriddle

Trying to reset my pourover recipe for my current bag of coffee beans, as the past couple of cups have been a little bitter.

  • Beans: “Cold Brew Blend” medium roast (Guatemala/Colombia) from Local Coffee Roasting Co. in Roxana, DE
  • 17g coffee / 250g water (1:14.7)
  • JX: 2 rotations (20 on the grind chart / 60 total clicks)
  • Water at 94°C
  • Recipe: A Better 1 Cup V60 Technique (see below)
  1. Make small indentation in center of coffee grounds
  2. 0:00: Pour 55g of water to bloom
  3. 0:10 – 0:15: Gently Swirl
  4. 0:45 – 1:00: Pour up to 100g total (40% total weight)

  8. 2:00 – 2:05: Gently swirl
  9. Drawdown finished around 2:45

A few notes: I’m back to the original grind setting that I used the first time I brewed the beans. I also used 17 grams of coffee (vs 18), and started out with the water a degree or so cooler. Last night, I rewatched the Hoffmann video linked above, and the only thing he did that I haven’t been doing was to make a small indentation in the center of the grounds, so I added that step. During the brew, I had previously been putting the kettle back on the base in between all of the pours, but today, with the exception of the longer pause after the initial bloom, I just held on to the kettle the entire time. This seemed to make the process more smooth and fluid. Lastly, I skipped the final “swirl”, but not intentionally — I just forgot. These tweaks all seem very minor, but collectively, who knows?

The cup turned out just fine. Nothing mind-blowing, but very drinkable. The first couple of sips tasted bitter, but then it mellowed out. I’ve noticed this phenomenon a lot, particularly with pourovers. For some reason, it seems even more pronounced with these beans. Not sure what causes it, but maybe it’s something to do with my palate. Anyhow, I’ll stick with this methodology for my next few cups, and see how it goes. I do want to try brewing these beans with the AeroPress some time in the next couple of days.

New Brew

lpaulriddle

I finally opened the last of the three half-pound bags of beans that I bought in Delaware in early July. These beans are from the same roaster, and the same countries of origin, as my recent bag of light roast. I’m wondering if they took the same blend of beans and just roasted them a little longer.

  • Beans: “Cold Brew Blend” medium roast (Guatemala/Colombia) from Local Coffee Roasting Co. in Roxana, DE
  • 18g coffee / 250g water (1:14)
  • JX: 2 rotations (20 on the grind chart / 60 total clicks)
    • 9/7: Grind setting 18 (54 total clicks) had better flavor
    • 9/8: Bitter today at 18. Will try 19 (57 clicks) tomorrow
    • 9/9: Still bitter at 19. What is going on? Maybe I am swirling too much…
  • Water at 95°C
  • Recipe: A Better 1 Cup V60 Technique (see below)
  1. 0:00: Pour 60g of water to bloom
  2. 0:10 – 0:15: Gently Swirl
  3. 0:45 – 1:00: Pour up to 100g total (40% total weight)
  4. 1:10 – 1:20: Pour up to 150g total (60% total weight)
  5. 1:30 – 1:40: Pour up to 200g total (80% total weight)
  6. 1:50 – 2:00: Pour up to 250g total (100% total weight)
  7. 2:00 – 2:05: Gently swirl
  8. Drawdown should finish around 3:00

This was a perfectly pleasant, if unspectacular, cup. It was a good strength, and well-balanced, with no bitter or sour notes, but not much in the way of complex flavors, compared to the beans that I just used up. I’ll probably try grinding the beans a little bit finer next time, just to see what happens. Also, I’d be remiss not to try using them for cold brew, so I’m going to do that soon (likely tomorrow afternoon). Could be there’s a reason they’re sold as a “cold brew blend”. 😀

Another ridiculously hot early September day on tap, but this morning’s ride to work felt like any other summer morning commute. In spite of dry conditions, I opted for the road bike, because I figured it’d be easier to avoid overheating during the ride home later this afternoon.

Update for 9/9: For some reason, the past two cups I’ve brewed using this recipe (setting 18 yesterday, 19 today) have been on the bitter side. Not sure what I’m doing differently, except to note that on 9/7, I’m pretty sure I forgot to “swirl” the V60 after the initial and final pours, and the cup turned out better. Could it be that the “swirling” is leading to overextraction? If that’s the case, I can try to either skip the swirling, or make the grind coarser. I may try door #1 first, and I may also try making a cup with the AeroPress, just for kicks.

Saturday Morning Update

lpaulriddle

Here’s what I brewed this morning:

  • Beans: “Angel Albino Corzo-Chiapa” medium roast (Mexico) from Amity Coffee Roasters in Greenwood, DE
  • 18g coffee / 250g water (1:14)
  • JX: 2 rotations less 6 clicks (18 on the grind chart / 54 total clicks) Note: subsequent cups at this setting tasted bitter — better at 2 rotations / grind setting 20 / 60 total clicks
  • Water at 95°C
  • Recipe: A Better 1 Cup V60 Technique (see below)
  1. 0:00: Pour 60g of water to bloom
  2. 0:10 – 0:15: Gently Swirl
  3. 0:45 – 1:00: Pour up to 100g total (40% total weight)
  4. 1:10 – 1:20: Pour up to 150g total (60% total weight)
  5. 1:30 – 1:40: Pour up to 200g total (80% total weight)
  6. 1:50 – 2:00: Pour up to 250g total (100% total weight)
  7. 2:00 – 2:05: Gently swirl
  8. Drawdown should finish around 3:00

This turned out just about perfect to my taste. I just have to make sure to remove the spent grounds immediately after the drawdown finishes to avoid the slight bitterness I alluded to yesterday. I have enough beans left for 4 more cups, and I don’t think I need to tweak this recipe any further (although I’m slightly curious to try the beans in the French press, just to compare). I’ll likely use this recipe as a starting point for my next bag, which is also a medium roast.

This morning was beautiful, with temperatures in the upper 50s/low 60s and low humidity. With a heat wave looming, I seized the opportunity and got out just before 8 and ran 10 miles. I am hoping to get myself conditioned to run 10 miles once a week over the cooler months, and after a few more of these, I should be ready to tackle my short-term goal of running the entire BWI Trail loop, which (according to gmap-pedometer.com) is about 10.7 miles.

This and That

lpaulriddle

I’m trying a new WordPress theme out. I had been using “Twenty Twenty” for a long time, but never liked that it didn’t have a widget sidebar. So, I’m trying one out called “Simple Life”. It’s responsive, has a sidebar, and seems fairly lightweight, without a lot of bells and whistles and other stuff I don’t need. So, I’ll probably use it for a while until I get tired of it.

As promised yesterday, I brewed a pourover cup of my medium roast Mexican coffee beans using 18 grams of coffee to 250 grams water (around 1:14) and it was just about the perfect strength. It did have a tiny touch of bitterness that I didn’t notice yesterday, but I think that was because I wandered away and let the coffee sit and drip for a little too long. I’ll fix that tomorrow, and if it’s not perfect, I’ll try it just a tiny bit coarser.

I did my usual Friday morning session at the climbing gym today, and felt pretty good after climbing 8 routes ranging from 5.10- to 5.11-. There definitely is a huge difference in my energy level between my morning and evening climbing sessions. I suspect part of it is because I typically commute 22-25 miles on the bike on the same days as my evening climb sessions, with the 8-mile homeward leg wrapping up an hour or so before I leave for the gym. Something probably needs to give there…

  8. Drawdown should finish around 3:00

This is the same V60 recipe I’ve been using for light roast, with 20g coffee (vs 15), proportionally more initial bloom water, and slightly lower water temperature. I wanted to try brewing a stronger pourover cup, and it appears I have succeeded. This tasted well-extracted and very rich. I’m going to try my next cup at 1:14 (18g coffee / 60g initial pour) and see how that turns out. Over the past 3 days, I’ve now brewed 2 different AeroPress recipes and 1 pourover cup with these beans, all at roughly the same ratio. Both of the AeroPress cups tasted weak, but the pourover was strong. The pourover method is obviously doing a better job of extracting the beans, which makes me wonder what I could be doing differently with the AeroPress. It’s pretty clear that just upping the ratio is not the answer. I suspect that I need to be grinding the beans a lot finer, and/or increasing the steep time. But, if I get consistently good results with pourover, I’m inclined to stick with that for the time being.

More Pourover Notes

My AeroPress has been a little bit neglected lately, as I’ve been really enjoying the pourover cups I’ve been brewing with my bag of light roast beans. Both the pourover and AeroPress methods take about 5 minutes (start to finish) to brew a single cup, so going forward, I’ll probably be using both, depending on the beans and (to an extent) my mood. Two things I’ve learned over the past week:

  • With pourover, small adjustments to the grind size seem to have a larger effect on the finished cup than with the AeroPress. The first few pourover cups I brewed tasted a little bit sour and under-extracted, but at just a slightly finer grind (6 clicks on my JX), I’ve been getting fantastic cups.
  • When brewing single cups with boiling water, the coffee will cool to a drinkable temperature faster if I use a room temperature ceramic mug instead of an insulated Hydro Flask mug, so I can enjoy it sooner and without burning my tongue. 😀
