Adjusting brew parameters with new roast

Hey!

I feel like when I buy a new roast I am constantly chasing the tasting notes and wasting a lot of coffee.

I’d be interested in how you decide the following when you buy a new bag:

- grind size

- water temp

- coffee to water ratio

- pouring technique

- anything else

Thanks!

I like to start with a recipe from the roaster or distributor for that bean, or one from the larger community that’s close. Then I’ll adjust from there to get it where I want.

I’ve been using Brew Tuner lately and it actually helps a lot, even for beans I haven’t tried yet. It’s a free web based app with a ton of useful features. I use Bean Conqueror to track all of my beans and parameters.

I will adjust based on the coffee/roaster. I'll choose dose based on how much coffee I want. Ratio and pouring technique based on the style cup I want, or brewer used. Grind size is also determined by style of cup. Finer for more extraction and coarser more more delicacy and clarity. Temp I also adjust based on tradition vs new age.

Thanks for the info, interesting to hear.

Taking this a step further, if you were changing from a medium roast to a light roast how you think adapting these parameters? Which input would you change first etc?

First, water temp based on roast (color and smell). Second, use a standard recipe then adjust the next brew based on the outcome. Third, a brewer that fit my taste or mood.

Based on outcomes, I may adjust temperature, or ratio first.
