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:

  1. Reduced target water temperature to 90°C
  2. 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.

    5 pours might be too many. Each time you pour, you remix the bed of grounds, letting fines settle into the filter more. In a perfect world, most of the filtering is done by the grounds themselves.

    Darker roasts extract more easily. I would definitely try a lower temperature. I have the plastic V60, though, so my temperature doesnt get affected much. You could try preheating your v60 first. My lazy method of preheating is just putting the v60 on top of my kettle as it’s warming up. You could do that without the lid on your kettle to really steam it to temp.

    Darker roasts are lighter, so 15g of a darker roast are more beans that 15g of a lighter roast, so you could decrease dose, but you are probably fine there. I dont think having a too high dose should make it bitter.
