[IDEA] Engineer's Coffee (Version 3): Coffee Beans + Updated caffeine extraction technique

[DATE] 2016, 1M, 9 __________________________ [INFO] This is engineer's coffee, refined through practice. Optimized for strength and low-cost. __________________________ [MATERIALS] Coffee beans, Coffee filter, mini-stapler, mixer. __________________________ [METHOD] 1/ Mix beans into powder, 2/ put ~3/4 tablespoon of powder into coffee filter, 3/ seal up filter with staple to make a "coffee bag", 4/ put two "coffee bags" into a water container, 5/ fill container with boiling water and close, 6/ wait 1 or 2 days for strong coffee; 1 week for strongest coffee. __________________________ [OBSERVATIONS / OPTIMIZATION] 1/ Its found that multiple smaller coffee bags produced stronger coffee than a single large coffee bag; 2/ Longer time submerged into boiling water seems to make the coffee stronger, however, there are diminishing returns; one week submerged = better strength, but two weeks submerged = better by just a little. At least one day submerged would provide "adequate" strength, which can be considered minimum. 3/ Multiple water containers can be used, so that coffee of good strength will be available at all time. __________________________
