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?
