Coffee "re-gassing" ??

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 "re-gassing" ??

I've been working on a batch of Guatemala Antigua beans from a local specialty coffee shop for about 2-3 weeks. For the first week or so, they were blooming quite nice and evenly with 2:1 water to grinds at 45 seconds in a Chemex. The resulting brews were so delicious!

However the last week or so, I've noticed a harsh/almost-burned smell coming from the beans that wasn't there before and the blooms are SO lumpy and 2-3 times larger than previously. The brews have become much more acrid/smokey/bitter and much less tasty. I took a break from them for 3 days and suddenly, terrible. What gives?? I've started double blooming just to get the bed to flatten and reduce some foam.

I store them in an Airscape at room temperature, out of the sun, and freshly grind them using an Ode2 at a medium grind setting (though I've been playing with coarseness to get brew time where I want it). Every other variable has been roughly the same. So why the sudden change in the bloom and how can coffee suddenly become gassier? Afaik, they should have released most of their C02 by now.

TLDR: My 2-3 week old beans are suddenly causing a much harsher brew with less delicious subtle flavors and blooms are 2-3 times their original size and very foamy.
