minimum dose size?

Jan 31, 2024 |

I use the Hario switch to brew my coffee and am trying to reduce my caffeine consumption. Hence I would like to brew smaller cups of coffee. I am currently using 10g of coffee with 160g of water. (1:16 Ratio) I am wondering if there is a minimum amount of coffee...

Coffee Fermentation Experiment #1

So I decided I want to test how a longer/2nd fermentation would affect the flavor of a coffee. I measured 1.4 lbs of Mexican Chiapas Coffee, and added the following for fermentation: 0.1 lbs honey raw unfiltered, 2 cups coffee cascara. I put it all in a large container and covered it all with water. I let it ferment for 4 days total, and dried it until it was its original weight of 1.4lbs.

It has a very new and distinct smell, cheesy is the best way to describe it. The color also became a mixture of green and brownish green.

I roasted it to a medium roast, along with the same coffee, but unfermented as a control. It took a very long time to expand, and was very quiet during first crack. The control was much louder.

The best way to describe the coffee pre fermentation is floral and smooth. A slight bite at the start and a nice smooth finish.

Post fermentation, after a day, that cheese-like smell has vanished. After brewing with a 1:15 ratio with pour over, its flavor is vastly different and super unique. It had zero bite to it at all and had a aftertaste that is best described as tasting like dill weed.

I just wish my palate was good enough to pick up more flavors.

I’m going to try this again with a few different coffees and tweak how I ferment it, any recommendations on what to change?
