Thanks for the addition to the group. Seriously considering building a drum roaster along the lines of oldgrumpus's. Love the design and craftsmanship.

Caffeine 'traffic light' detects coffee jitter levels
Dan
Cute idea, if only it had more precision than just three levels. The title is mistaken. Coffee "jitters" doesn't come from caffeine, but a yet to be identified chemical in coffee, but not tea or chocolate.

The science behind the invention is here:

1 pound electric sample roaster, 3 pound direct-flame roaster, both handmade; modified Mazzer Mini grinder, LaSpaziale Vivaldi II automatic espresso machine. When the electricity goes out I make vacpot coffee from beans ground on my Zassenhaus hand grinder, and heat the water with a teakettle on the gas range.
