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. http://news.cnet....er-levels/ The science behind the invention is here: http://www.nature...02255.html 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.
