Hello, So far I’ve kept my single-cup V60 recipe fairly stable. 15g coffee and 250mL of water, pour water by 50g increments with 10s time in between pours. It usually gives me a brew time around 2’30" which is generally considered good. I adjust the grind size on my manual grinder depending on the beans and I’ve been satisfied with the results so far.
Now the problem: I started new beans, higher roast, lower density. With my usual method I get a very short brew time, less than 1’30". Finer grind size quickly becomes too bitter.
I am not questioning the quality of the beans, more my recipe. I suppose I’m not getting the best out of these beans.
What would you suggest to improve my recipe for these beans?
- Adjust coffee to water ratio ? What should I look for to find the correct ratio ?
- Change brew temperature? I usually boil my water to near 100°C as it will cool quickly in the porcelain V60.
- Any other suggestions?
Update: thank you all for the interesting suggestions. With this morning brew, I made 2 changes:
- Reduced target water temperature to 90°C
- 50g bloom and the rest of the water in 2 pours
The results are improving, very pleasant cup. The brew time was still pretty short. Next, I will try to decrease the grind size by a few ticks to see if I can get more flavors without increasing bitterness.
In my experience, it’s all about grind size. If your target brew time results in too bitter a brew, I don’t see how you would avoid a shorter brew time for these beans. If it’s hard to hit the brew time you are aiming for, you might have success with another grinder. It shouldn’t be necessary to touch brew ratio and temperature unless you’re really fine-tuning taste.
