Brew Notes (new bag)

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: “Columbia Sierra Nevada” medium-light roast
  • Roaster: Zeke’s Coffee (Baltimore, MD)
  • 17g coffee / 250g water (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 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 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.

Update (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.

After-dinner brew

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.

Latest AP Attempt

lpaulriddle

After a few days of dodging it, we finally got a significant, torrential rainstorm last night. It poured for a couple of hours and I suspect we got 2-3″ of rain (one of these days, I need to buy a rain gauge, so I’ll know for sure). It was the first real test for our new driveway trench drainage system, and it seemed to go fine, as we had no water in the basement except for wetness behind the bar, which is a known issue. In theory, the drain should keep a lot of water from reaching the sump pump on the east end of the house, so the pump should not run as often any more. In practice, the jury is still out. The pump still runs occasionally, but I need to hang around it for a while during a heavy rainstorm to get a better sense for how often it runs now. Last night, I rode the storm out in bed. This morning, I rode to work through Patapsco Valley State Park, and the only evidence of flooding I saw was on the road near the parking for Lost Lake and the Grist Mill trailhead, which is a common trouble spot. No issues on the trail itself — the new bridges seem to be working great. Overall, the trail (and the park in general) was in much better shape than it would have been a few years ago after a similar rainfall event.

Here was this morning’s AeroPress experiment:

  • Beans: “Cold Brew Blend” medium roast (Guatemala/Colombia) from Local Coffee Roasting Co. in Roxana, DE
  • JX: 2 turns minus 6 clicks (Grind setting 18)
  • 95°C water
  • 17 grams coffee / 220 grams water (1:13)
  • One new paper filter (pre-moistened)
  1. Set AeroPress up in standard orientation and add coffee
  2. Add all water at once, spinning brewer to wet coffee while pouring, ending by around 0:10
  3. Stir several times
  4. Insert plunger, then pull up to create a vacuum
  5. At 1:15, remove the plunger and stir several times again
  6. Re-insert the plunger and press gently, finishing between 1:50 and 2:00

This recipe comes from stumptowncoffee.com, and is similar to the instructions that ship with the AeroPress. There are small, likely negligible differences in the amount of coffee and the water temperature, but the main difference is that this recipe adds a little bit of stirring right before pressing. I didn’t zero my scale until I had already poured a little bit of water, so the total volume may have been off a little bit, but I suspect not enough to really matter. I’m probably starting to sound like a broken record, but this brew was similar to the last several I’ve done in the AP: the flavor was fine, but the body was thin. The quest for fuller-bodied AeroPress coffee will continue, but I may take a break and go back to pourover for a little while.

Another Monday

lpaulriddle
  • Beans: “Cold Brew Blend” medium roast (Guatemala/Colombia) from Local Coffee Roasting Co. in Roxana, DE
  • JX: 2 turns plus 6 clicks (Grind setting 22)
  • 90°C water
  • 13 grams coffee / 180 grams water (about 1:14)
  • One new paper filter (pre-moistened)
  • Recipe: 13g that makes you happy (inverted: add 30g water, stir 5x, top up to 180g at 0:30, stir 5x, flip at 1:30 and press very slowly, finishing at 2:30)

First stab at brewing a (hot) cup with these beans in the AeroPress. This is a recipe I’ve used quite a few times before, but recently, I’ve been using more coffee than the recipe calls for, in an effort to get richer-tasting cups. Based on my experience with pourover, I think there should be a way to achieve this without using so much coffee. Today, I went back to a 1:14 ratio, which is what the recipe calls for. According to my notes, I have previously used a JX grind setting of 24 or 25 (around 2.5 turns) every time I’ve brewed this recipe. For today’s cup, I went with 22, which is a lot finer, and similar to what I’ve been using for a lot of my pourovers. This cup was not bad overall — it still was not quite as rich as a pourover at the same ratio, but it wasn’t weak, either, and had no bitter or sour notes. One thing I have noticed with these inverted AeroPress recipes is that after steeping for a while and then flipping, a bunch of coffee grounds frequently end up stuck to the plunger. I could prevent this by briefly stirring right before flipping, or by flipping immediately after the initial stir and letting it steep in the “standard” orientation. I might try one or both of these next time, just to see if it makes any difference.

I had a fairly routine bike commute to the office this morning. I woke up at 5:30 to another pre-dawn deluge, but it cleared out of the area in time for me to get out of the house on time. I have found that 7:20 is the absolute latest I can get rolling if I don’t want to deal with foot and bus traffic for the nearby middle school. If it had rained much longer, I likely would have ended up telecommuting. The Patapsco River was running higher and faster than I had seen it all summer, and a lot of the little feeder streams were really raging. The areas to the west of us have gotten hammered with rain over the past few days, and this morning’s downpour hit those areas as well.

Update (9/12): I brewed the same AeroPress recipe again, slightly finer (grind setting 21) and I flipped right after filling to 180g and stirring. It made no discernible difference. If anything, it tasted slightly weaker — again, not unpleasant, just lacking in body. I did notice that, while the plunger started out clean, grounds started getting stuck to it as I was plunging. So, it appears that the issue isn’t that they get stuck there during steeping, but more so that they just accumulate there while plunging. Seems like this would be unavoidable, and given that the finished product wasn’t an improvement, there’s no need to use a different technique from the recipe. I may try one more AeroPress experiment with these beans (not sure exactly what yet) and then I’ll just switch back to pourover to use them up.

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)
  5. 1:10 – 1:20: Pour up to 150g total (60% total weight)
  6. 1:30 – 1:40: Pour up to 200g total (80% total weight)
  7. 1:50 – 2:00: Pour up to 250g total (100% 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.

Today’s Cold Brew

lpaulriddle
  • 15 grams “Cold Brew Blend” medium roast (Guatemala/Colombia) from Local Coffee Roasting Co. in Roxana, DE
  • JX: 2 rotations minus 6 clicks (54 total clicks or 18 on the grind chart) for a medium to slightly fine grind
  1. Set AeroPress up in inverted orientation with plunger inserted about 1cm, and add coffee.
  2. Fill AeroPress to within about 1cm of the top with room temperature, filtered water.
  3. Start timer and stir vigorously for 1 minute.
  4. Flip AeroPress and press gently into an 8-ounce tumbler.
  5. Add a drop or two of stevia and stir.
  6. Add 2 or 3 ice cubes to chill.

For kind of obvious reasons, I wanted to try making cold brew with these beans at least once. This was only my second time making AeroPress-style cold brew with freshly ground coffee. I have made most of my cups using Wellsley Farms Breakfast Blend pre-ground coffee, but we’re out of that. Last week, I tried making cold brew with Maxwell House Original Roast, but did not like it at all. Today’s cup turned out pretty good: probably a slight step up from the Wellsley Farms, but not leaps-and-bounds better. I went with the same grind setting I used last time for cold brew, which, coincidentally, is the same setting I used for my pourover cup this morning. The brew was pretty strong — as I wrote the last time I did this, I could probably get away with using less coffee, or diluting it a little bit. I’m curious what this would taste like if I made it the old-fashioned way (24 hour steep in the French press) but that would probably use up almost all of the beans I have left.

Morning notes

lpaulriddle

Summer 2023 continues to go out like a lion, with another mid-90s day with high humidity on tap. Should be a good afternoon for a swim, but after several bone-dry days, thunderstorms are finally back in the forecast, so I’ll need to keep an eye on the weather. I managed to run 10K this morning, but once again, it was rather sweaty. Can’t wait until fall!!

I brewed cup #2 with my latest bag of coffee beans today, with a little bit finer grind, and it was a better cup than yesterday’s. The finer grind seems to have brought out some extra flavors that weren’t there yesterday, without making it bitter. It will be interesting to see how it goes with the next few cups.

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.

Morning Notes

lpaulriddle

We are in the midst of the most intense and prolonged early-September Mid-Atlantic heat wave that I can remember. It’s fairly common to have days in September that top 90°F, but the past two days have pushed 100°, and the heat is expected to last until Thursday. The saving grace is that the dewpoints have been a little bit below what is typical for mid-summer, making things slightly more tolerable, and there’s less daylight and lower sun angles this time of year. I did manage to get out for a run this morning. I left the house at 7:10 and ran 5 miles. I hope to get out for a swim later this afternoon.

I’m down to the last cup of the coffee beans I’ve been brewing for the past week or so. After several near-perfect pourovers, my last couple of cups have been a little bit on the bitter side. Not quite sure why that is, but I may try making the grind a little bit coarser for my final cup. Then, depending on how that turns out, I’ll decide on an initial recipe to try with my next bag of medium roast beans. I only have one half-pound bag of beans left, so it’s going to be time to buy a bag or two soon. I’ll likely go back to one-pound bags, and may check out a local roaster like Zeke’s Coffee, which the grocery store down the street from me carries.

Just a quick update: I brewed the last of the beans this evening after dinner. Exact same recipe, except I had 19 grams of beans left (so the cup was a little bit stronger) and I ground them slightly coarser at 2 turns on the JX, or grind setting 20. This turned out great, without any hint of bitterness. Once again, a small adjustment to the grind made a big difference. Curious how things will go with my next bag.

Morning Brew

lpaulriddle
  • Beans: “Angel Albino Corzo-Chiapa” medium roast (Mexico) from Amity Coffee Roasters in Greenwood, DE
  • 20 grams coffee, 280 grams water (1:14 ratio)
  • French press
  • Gooseneck kettle
  1. Preheat French press
  2. Heat brew water to 95°C
  3. Coarse grind (JX setting: 3 rotations + 4 clicks or 94 total clicks)
  4. Start timer and pour at the same time
  5. 60 second bloom (including pour time)
  6. Stir a few seconds until grounds settle
  7. Steep 6 minutes

This is my standard French press recipe, with slightly more water to get a 1:14 ratio vs 1:13. Just wanted to try it with these beans. The cup turned out fine, with more earthy and roasty notes than the pourover recipe I’ve been using. Overall, I think I prefer the pourover, but would be fine drinking this every day. Where the pourover (and AeroPress) win is convenience: both methods are faster and less messy than the French press.
