Zeke’s Charm City Blend

lpaulriddle
  • Beans: “Charm City Blend” from Zeke’s Coffee (Baltimore, MD)
    • Roast level: Dark (6/8)
    • Origin: Colombia (Sierra Nevada)
    • Roast date: 8/19/24
    • Purchase date: 8/20/24 at Green Valley Marketplace in Elkridge, MD
  • AeroPress:
    • 20g coffee / 250g water
    • JX: 30 (90 clicks)
    • Water at 90°C
    • Prismo with metal + paper filter
    • Pour all 250g; stir front to back (carefully) until all grounds are wet; steep until 2:45; stir 6x; press slowly

The local grocery store has always carried these, but this is the first time I have tried them. From the description, it’s a blend of dark (Italian-roast) beans with a bunch of random lighter-roasted beans. No origin listed, as I guess it varies from bag to bag. It looks and tastes like a dark roast, so that’s how I’ve been brewing it. Grind settings 20 and 25 were too bitter, but 30 produced a fairly smooth AeroPress cup. French press with the same grind setting tasted similar. 20g coffee and 250g water just barely fits in the AeroPress cylinder in standard orientation. I probably could not brew this amount without the Prismo attachment.

8/28: AeroPress cups have been pretty consistent and smooth, with only an occasional, slight note of bitterness, but not unpleasant and not more than you’d expect from dark-roasted beans. The taste is a tiny bit reminiscent of Verona St Julien’s Breakfast Blend, which is probably my favorite among the darker roasts I’ve brewed to date. Unfortunately, though, my last two French press cups at the office have not been good. I have been using 24g coffee to 300g water (same 1:12.5 ratio as AeroPress) with the James Hoffmann French press method and grind setting 30 (again, same as AeroPress) and the cups have been unpleasantly bitter with kind of a strange aftertaste. Obviously, something needs tweaking, but I’m not sure I’ll be able to experiment much more, as it’s likely I’ll be running low on beans by the next time I come to the office. Assuming I have any left by then, I may just end up bringing the AeroPress to the office, so I can brew it the same way I do at home.

8/31: As an experiment, I brewed my past 3 cups without a paper AeroPress filter, using only the metal filter that came with the Prismo (no paper filter), and I think I prefer it this way — the cups seem to have a sweeter flavor with a richer texture/mouthfeel, at the expense of a little bit of sediment in the cup. This could be subjective, as I haven’t done a blind taste test (and don’t have enough beans left to do one now) so I’ll have to experiment a little bit more and see what types of roasts taste better without the paper filter. I suspect it may work better with darker roasts than lighter roasts, but as always, I could be wrong.

Zeke’s Beans of Summer

lpaulriddle
  • Beans: “Beans of Summer” from Zeke’s Coffee (Baltimore, MD)
    • Roast level: Light (3/8)
    • Origin: Indonesia, South America, Central America
    • Roast date: 7/8/24
    • Purchase date: 7/8 or 7/9/24 at Green Valley Marketplace in Elkridge, MD
  • V60:
    • 21g to 22g coffee / 300g water
    • JX: 20-25 (60-75 clicks)
    • Water at 99°C
    • Recipe: Single Cup V60 Pourover with size 1 dripper
  • AeroPress:
    • 18g coffee / 250g water
    • JX: 20
    • Water at 99°C
    • Prismo + metal and 1 paper filter
    • Pour to 50g / stir to wet / bloom until 0:45 / top up to 250g / stir 5-7x front to back / steep until between 2:30 and 3:00 / stir 5-7x again / press slowly

I bought these close to the day they were roasted, and let the bag sit for 10 days or so before opening it. First cup in size 2 dripper at grind setting 20 was pretty good. Second cup at setting 19 was good as well. Started getting a little bit of bitterness at 18. Backed off to 20, and it was still bitter. Tried setting 20 in plastic size 1 dripper and later in the ceramic size 1 dripper, and both cups were good. I’ll keep it there for the time being and see how it goes.

Like most Zeke’s beans, these appear to be washed, leave very little fine residue in the grinder, and drain down quickly in the size 2 dripper and even faster in the size 1. I’m wondering if these beans are similar to Zeke’s Snow Day Blend, which required a really coarse grind in the larger dripper. Maybe the key to avoiding bitterness with these is to make sure they finish draining down by 2:20 to 2:30, which would make the coarser grind appropriate for the larger dripper.

7/26: These are starting to want a coarser grind now no matter which dripper I use. I tried setting 25 with size 2 V60 this morning, and it wasn’t bitter, but not what I would call a perfect cup either. It seemed maybe a little bit under-extracted. I wonder if it would be better if I went back to a finer grind and dropped the water temperature 10 degrees or so. I might try that this afternoon.

7/28: Ignore most of the above. It has proven challenging to get a good cup with these beans with the V60. Grind setting 20 with 90C water was bitter. Setting 30 at 100C was sour and under-extracted. I think the coarser grind is the appropriate setting for pour-over, but with the V60 (both sizes) It seems like the water is draining too quickly for proper extraction. It might turn out better if I brewed a larger quantity at a time (say 500-600g). Maybe a thicker filter would help, if such a thing exists. Or, perhaps a different style of dripper (Kalita Wave?) would give better results. For today, I switched to the AeroPress (recipe above) and it produced a much better cup than anything I’ve gotten with the V60 recently. I’ll probably stick with that until the beans are used up.

Amity Costa Rica (Terrazu)

lpaulriddle
  • Beans: “Costa Rica (Terrazu)” from Amity Coffee Roasters (Greenwood, DE)
    • Roast level: Medium (wet process)
    • Origin: Costa Rica
    • Tasting notes from bag: clean sweetness / floral
    • Roast date: 6/11/2024
    • Purchase date: 6/16/2024 at T S Smith & Sons in Bridgeville, DE
  • AeroPress:
    • 20-21g coffee / 250g water
    • JX: 18 (54 clicks)
    • Hot water from Cuisinart machine (pretty hot but not boiling)
    • Prismo with metal and paper filters
    • Pour to 250g and stir 6-7x; steep until 2:45; stir 6-7x; press slowly, finishing up somewhere around 4:15

I have brewed this recipe 5 or 6 times now at our beach house, and the cups have been pretty consistently good. I’ll almost certainly be bringing some home, so I’ll try it in the V60 next week and see how that compares.

6/28: At home, I’ve been using the same recipe with my gooseneck kettle and 95°C water. The past few cups have been very slightly bitter. I tried dropping the temperature to 90°, but it still was not quite as good as last week’s cups. I only had about 30g of beans left, so today, I brewed all of them with the V60 (size 2) and 450g of water at 95°, and I also backed the grind off 6 clicks to setting 20. The result was a very good, smooth cup. Seems that making the grind slightly coarser is the ticket with these beans as they start to age. They were only 17 days past roast date when I used them up.

Zeke’s Market Blend (second bag)

lpaulriddle
  • Beans: “Market Blend” from Zeke’s Coffee (Baltimore, MD)
    • Roast level: Medium (5/8)
    • Origin: Central and South America
    • Roast date: 5/13/2024
    • Purchase date: (TBD) at Green Valley Marketplace in Elkridge, MD
  • AeroPress:
    • 18-19g coffee / 250g water (1:13 to 1:14)
    • JX: 25 (75 clicks)
    • Water at 90°C
    • Prismo with metal and paper filters
    • Pour to 50g, stir to wet, and bloom until 0:45; top up to 250g and stir 5-6x; cover and steep until 3:00; stir 5-6x; press slowly

This is my second bag of these. I previously bought them last October, and I settled on kind of a convoluted V60 method where I used hotter water to bloom the grounds and then diluted the water to cool it before brewing. I didn’t want to go to that much trouble, so this time, I just tried V60 with 90°C water and grind setting 20(?). This was similar to what I did the first few times with the last bag, and the results were similar, too — it was on the bitter side. Since the beans are ever so slightly on the darker side of medium, I decided to try the AeroPress, which I don’t believe I had used at any point with the last bag. After an initial bitter cup at grind setting 20, I settled on the above, which was smooth and chocolaty. Rereading my first linked post from October, it looks like I ended up at a slightly finer grind setting (23) with V60, which is interesting, because I usually end up grinding finer with the AeroPress than with pourover. However, every bag is different, and taste always wins out over what seems logical on paper.

5/27: For the past couple of cups, I have reverted to a similar technique to last fall’s, using the AeroPress instead of V60: Heat water to 99C; pour to 50-60g; stir to wet; cool kettle water to 82-86C; bloom until 0:45; top up to 250g and stir 5-6x; cover and steep until 3:00; stir 5-6x; press slowly. Today’s cup was the best so far, and I used 20g coffee at grind setting 22 (2 turns + 6 clicks). It was a nice, smooth, rich cup. This brewing technique seems to work well with Zeke’s Market Blend, but I’ve never tried it with any other beans. I wonder if it would be worth trying with some other medium to dark roasts. The only downside is that it adds an extra step to the process, and sometimes (particularly first thing in the morning) I’d rather just keep things simple.

Zeke’s BirdSong

lpaulriddle
  • Beans: “Bird Song” from Zeke’s Coffee (Baltimore, MD)
    • Roast level: Medium/Dark (6/8)
    • Origin: Central and South America
    • Roast date: 4/15/24
    • Purchase date: 4/22/24 at Green Valley Marketplace in Elkridge, MD
  • AeroPress:
    • 21-22g coffee / 250g water (1:11 to 1:12)
    • JX: 19 (57 clicks)
    • Water at 85°C
    • Prismo with metal and paper filters
    • Pour all 250g and stir 5-6x; cover and steep until 3:00; stir 5-6x; press slowly

I brewed the first few cups at 95°C. For a couple of them, I included a 45-second bloom step and steeped until 3:00; for a couple others, I skipped the bloom and steeped until 2:30. I didn’t notice much of a difference. The cups were a tiny bit on the bitter side, but not enough to be unpleasant. There was no acidity and not much in the way of complexity — more or less what you would expect from a darker roast, and not bad, but nothing to write home about, either. This afternoon, I dropped the temperature to 85°, and it made a big difference. The bitterness was gone, and the cup was rich and full-bodied. I’ll keep brewing it like this for the time being. I bet that this would also make really good French press coffee.

5/2: The past couple days’ cups were starting to taste a little bitter (right around 2 weeks past roast date), so I backed the grind off to 20 this morning. It would probably be good at anywhere from 18-20. The only issue I have with coffee brewed at 85°C is that sometimes it cools off more than I would like. Cooler cups can be good in the summertime, but a few options for a warmer cup would be:

  • Preheat the mug using water from the insta-hot or leftover hot water in the kettle. The former bothers me because it seems like it wastes water and energy. The latter seems inconvenient with the AeroPress, because once the water is heated, the brewer sits on top of the mug, unless I brew with it inverted.
  • Use an insulated mug instead of ceramic
  • Brew a stronger ratio and then dilute with hot water

5/5: I used the last of these up today. I settled on setting 19 for my last several cups, and they were pretty good.

Verona St Julien’s Breakfast Blend

lpaulriddle
  • Beans: Julien’s Breakfast Blend from Verona Street Coffee (Dubuque, IA)
    • Origin: Central America / Indonesia
    • Roast level: medium to medium/dark (3/5 per web site)
    • Purchase date: 3/20/24 at Hy-Vee Grocery Store in Omaha, NE
  • AeroPress in hotel room:
    • 1 heaping AeroPress-sized scoop beans plus “a little more” (18-20g)
    • JX Grind Setting 20 (60 clicks)
    • Prismo with 1 paper filter and metal filter
    • Heat water to boiling in microwave
    • Start timer and pour enough to wet grounds
    • Stir and let sit for 45 seconds
    • Top up to about 1/2″ below top of AeroPress chamber
    • Stir front to back 5 or 6 times
    • Steep until 3:00
    • Stir front to back 5 or 6 times
    • Press slowly
  • AeroPress with measurements:
    • 18g coffee
    • 250g water at 95°C (ratio 1:13.9)
    • 50g initial pour
    • Everything else same as above
  • Tasting notes: roasty, smooth, full-bodied

I bought a 12oz bag of these beans at the beginning of our NCAA Tournament trip to Omaha. There was no roast date listed on the bag. The web site lists the origins as Central America and Indonesia, and the roast level as 3 out of 5. I’d definitely call this a medium/dark roast, based on the appearance of the beans (dark and oily), as well as the aroma and taste. My first cup at grind setting 15 was bitter, so I backed off a half turn to 20, and the subsequent cups have been pretty smooth and tasty, in spite of inexact brewing parameters and hotel room tap water. It will be interesting to compare when I get home and try them with the V60.

3/26: I brewed an AeroPress cup at home today, using the same technique I used at the hotel, with more precise measurements (see above). The flavor and strength were similar to the hotel room cups, but I think it was slightly better overall, probably due to higher brewing temperature and/or better water quality (filtered vs straight from the tap). I may end up just brewing all of these beans with the AeroPress, as I like how the cups are turning out, and “if it ain’t broke, don’t fix it”.

3/31: For the past 2 or 3 days, I’ve been brewing 300g cups with grind setting 20, 21-22g coffee, and 250g brew water at 95C (about the max that will fit in the AeroPress) and then diluting with 50g of bypass water. The cups have tasted similar to the earlier ones I’ve brewed, so this seems like a good way to get a larger cup.

4/8: I brewed my last 12g of beans with 120g water (1:10) using the same AeroPress recipe I’ve used all along, except I skipped the bloom step and just poured all of the water at once. I really liked the result — it was strong, rich, and smooth, and just about the right amount. I think a larger cup would have worn out its welcome — kind of like an imperial stout, a little bit of really strong coffee goes a long way. I’m not sure how widely available this brand is at retail outside of Nebraska/Iowa, but I’d certainly buy it again.

Travel Brewing

lpaulriddle

Last week, I took my first stab at brewing decent coffee while traveling. Here’s what I packed:

  • AeroPress, plus:
    • scoop
    • stirring paddle
    • several paper filters
    • Prismo accessory with metal filter
  • 1Zpresso JX hand grinder
  • Zeke’s Snow Day Blend beans (in a mason jar)

I put all of this into my checked bag. TBD is whether I’ll be able to fit all of this into carry-on bags. Glaringly absent: a scale, a mug, and a way to heat water. I measured beans by volume using the scoop. To heat the water, I used drip coffee machines at three different hotels, and a Keurig at the house where I stayed the final two nights. I used bottled water in the hotel rooms, and tap water with the Keurig. I was a little bit worried that the typical paper hotel room coffee cups wouldn’t hold up to brewing with the AeroPress, but they worked just fine (granted, I didn’t press very hard).

Figuring that the coffee machines wouldn’t get the water quite up to full boil, I went with a medium roast. I could probably have used a darker roast as well. For a light roast, I’d probably want access to a stove or microwave to bring the water to full boil.

To brew, I used a medium/fine setting of 15 on the JX, which is 1.5 turns. I used 1 heaping scoop of beans plus “a little more”, depending on how strong I wanted the coffee. I used a paper filter in addition to the metal Prismo filter. I then added the grounds, heated 1 paper coffee cup full of water in the machine, and filled the AeroPress up enough to cover the beans, stirred, and bloomed for 45 seconds. I then filled the AP up to near the top. No need to use two cups for this, as the Prismo keeps the water from leaking out (lacking a Prismo, I could probably also have inverted the AP). Then I stirred back-to-front a few times, steeped until around 3:00 (using my phone as a timer), stirred again, and pressed slowly. The resulting coffee was not bad. It was not quite as good as a perfect pour-over cup, but it was well-flavored and well-bodied, and fairly consistent from day to day. I’ll likely try this again the next time I travel.

Orinoco Ethiopia Yirgacheffe

lpaulriddle
  • Beans: “Ethiopia Yirgacheffe”
    • Medium roast
    • Roaster: Orinoco Coffee & Tea, Ltd. (Jessup, MD)
    • Roast date: Unknown (best by 10/28/24)
    • Purchase date: 2/20/24
  • 20g coffee / 300g water (1:15)
  • JX: 30 (90 clicks) for V60; 13 (39 clicks) for AeroPress
  • Water at 95°C
  • Recipe: Single Cup V60 Pourover, Light/Medium Roast AeroPress (TBD)

Taking some time to get this dialed in with the V60. I started at grind setting 20, and it was way too bitter. I brewed a couple of cups around 25/26, and they were less bitter, but still lacking. I backed off to 30 today (2/23) and it was the best cup so far, but seems like it could be better. The V60 drains really quickly at this setting: it is mostly finished by 2:30.

For AeroPress, I used this recipe with 250g water, 17g coffee, and grind setting 13. The flavor was good, but it was a little bit lacking in body, so I’ll start nudging it finer.

2/24: Brewed AeroPress with grind setting 12 this morning, and it was unpleasantly bitter, which kind of surprised me, given how it turned out at 13 yesterday. This afternoon, I brewed V60 at setting 29, which seemed a little better than 30. Will try at 28 tomorrow.

2/25 (morning): (V60) bitterness creeping in at 28. Seems like 29/30 may be the best setting. Could this be an issue with the beans being too “fresh” again? I wish I knew the exact roast date..

2/25 (afternoon): Went back to setting 29 with V60, and it was the best cup I’ve had to date. The only difference from yesterday afternoon’s cup was that I stirred the grounds with a spoon during the bloom phase instead of swirling.

2/27: Even 30 was bitter yesterday!! 32 was better today, but thinking 31 might be the sweet spot (today, at least 😀). This was the first time I had ever used a setting coarser than 30. These beans are behaving similarly to the last two bags of Zeke’s beans that I started brewing just a couple of days after the roast date. This lends credence to my theory that they may have been too “fresh” when I started brewing them.

3/1: I never quite figured out how to get a consistently good cup with these beans with the V60. However, I brewed a very good cup with the AeroPress this morning: 17g beans to 240g water (around 1:14), Prismo + metal and paper filters, 95°C water, JX grind setting 15 — pour 50-55g, stir, bloom until 0:45, top to 240g, stir 4x, steep until 3:00, stir 4x, press slowly. This cup was full-bodied and strong, with good flavor. That was the last of the beans, but noting this as a good starting point for when I eventually buy more of them.

Rise Up Organic House Roast AeroPress

lpaulriddle
  • Bean info and V60 pourover notes
  • 16 to 17g coffee to 250g water (around 1:15)
  • Prismo with metal and paper filters
  • Grind setting 12 14
  • Water temperature 95C
  • Add coffee, start timer, pour 45 to 50g water
  • Return kettle to base, stir to wet grounds evenly, and bloom until 0:45 (I just left the stirrer in the AP for this step)
  • Top to 250g water and stir front to back 4 or 5 times, finishing around 1:15
  • Cover and steep until 3:15
  • Stir front to back 4 or 5 times again
  • Press gently, finishing around 4:30

This is pretty much the same technique I used with Zeke’s Hippie Blend (a light roast) recently, except I stirred instead of swirling during the bloom step, and I also steeped it about 45 seconds longer. This cup was not bad, but tasted slightly over-extracted, so I’m probably going to want to grind the beans a little bit coarser next time. I’m thinking about trying setting 14.

2/8: I’m almost out of the beans, but noting for posterity that setting 14 was pretty good. I didn’t steep quite as long (maybe until 3:05) but doubt that made any difference.

Zeke’s Hippie Blend AeroPress

lpaulriddle
  • 16 to 17g coffee to 250g water (around 1:15)
  • Prismo with metal and paper filters
  • Grind setting 18
  • Boiling water (100C)
  • Add coffee, start timer, pour 45 to 50g water
  • Return kettle to base, Swirl AP gently, and bloom until 0:45
  • Top to 250g water and stir 4 or 5 times, finishing around 1:15
  • Cover and steep until 2:30
  • Stir 4 or 5 times again
  • Press gently, finishing around 3:30-3:40

This made a pretty good cup. It had no bitterness, and the body and flavor actually seemed better than the pourovers I have been making recently with these beans. I wonder if the cooler ambient air temperature this time of year is affecting the extraction of the pourovers.

I had been wanting to get back to occasionally brewing lighter roasts in the AeroPress, since I’ll likely be doing it a lot while traveling, where I won’t have precise control over the temperature of the water, or access to a scale. This seems like a good first stab. The recipe is very similar to what I’ve been using for dark roasts, but adds a bloom step. I used the scoop that came with my plastic V60 dripper to measure the beans, and also weighed them, and it seems that 16-17 grams translates to one slightly heaping scoop of beans. I’ll have to try this with a couple of different light roasts to see how much variance there is between them. Then, I’ll just need a way to eyeball the amount of water, and I expect that I can use the markings on the AeroPress cylinder for that. The Prismo definitely makes this easier, as it keeps the water from dripping out through the filter without the need to invert the AP.

1/21: I brewed the same recipe today with Zeke’s Holiday Roast (a medium roast) except I dropped the water temperature to 95C. It produced a perfectly OK cup that was neither better nor worse than my V60 cups. I have a feeling it would benefit from a little bit of tweaking, but as I’m almost out of the beans, I’ll likely just go back to V60 to use them up.
