How to Best Brew Anaerobic Natural Coffee

Coffee preparation techniques besides espresso like pourover.

#1: Post by Elemsee »

I'm wondering what I should be considering when specifically brewing anaerobic natural processed coffee, specifically light roasts, and for pour over/hario switch methods. I just received 3 anaerobic naturals from Red Rooster - I know they are wonderful offerings, but I'm having trouble getting solid tasting brews, and my results are even difficult to assess whether they are over or under extracted - usually it's pretty clear to me but I'm striking out.

Should coffees undergoing this process be ground finer? Brewed at higher/lower temperatures? Benefit from less/more pours?

For reference, I have a C40 grinder & Ode grinder, a roster of drippers (Kono, kalita wave sandstone, switch, origami, stagg x, & torch), and use third wave water.

Any help is greatly appreciated! Thanks

I would reach out to Red Rooster. Roasters will often test their coffee with pour over methods and will probably give you at least what works for them not to mention recommending a resting period. Broadly however my queues start from the roast not processing method and a light roast would be straight off the boil and finer.

To confirm this try cupping the coffee with different temps at 5 degree steps, 100c, 95c, 90c, etc... If you're having a hard time pulling out if its under/over contrasting it helps to pull out the differences. Such as which is more sour a, b, or c etc... (If it's too nuanced try larger steps) you should at least be able to pull out the one you prefer even if you can't articulate why and with hope land on a temp that works best.

You can do the same for any detail you're unsure about like grind level. I would test it with off the boil water but the key is to only test one thing at a time and to contrast it as the contrasting will help you figure out what is working and what is not and 3 is a good number for contrasting. Probably temp and grind will be the most practical to test for cupping. 3 equal sizes cups, 15gr of coffee in each, 200gr water, brew for 4 min, break crust skim surface and wait for another 5 for coffee to settle/cool.
