Morning Gentlepeople.

As a coffee newbie I am having some small issues while trying to improve my game. I have a Oracle Touch and subscrube to a local monthly coffee delivery, so my beans change weekly.

My issue is that the grind setting is incredibly different from bean to bean. With my last bag, grind 14 gave a perfect 1:2,5 ratio. With a different bean today, I had to discard two cups before learning that grind size 3 gave me the same ratio. 14 gave me 1:3,5 which tasted rubbish.

The problem is that I got channeling and very little crema.

I guess the questions are: do different beans require completely different ratios or am I doing something very wrong?
Should I accept a very high ratio to avoid channeling on certain beans?
Or should my timer be lower on certain beans?

Thanks in advance for any help and have a great cup this morning!

    It’s starting to dawn on me that you might be right.

    I think I’ll keep trying different beans to test a lot of different coffee before landing on one variety and order that instead.

    I’ve gotten a lot of really good advice here today that I’ll use in my future brewing career.

    Thanks for taking the time, mate!

      If you’re gonna do that you can also try cupping beans first to get a sense of what they taste like before properly extracting them. I roast as well and this always helps get like the essence of the bean/roast profile’s taste down so I know how I want to extract.
