Some days, I brew coffee that tastes award winning! Other days, I brew coffee that tastes like a chemical hazard. I figured if I wanted to improve, I ought to be more aware about what I'm doing currently, and thus I began to keep a tiny journal.
This tiny journal became a spreadsheet, became a series of spreadsheets, became... this, Brewing by Numbers. I made this for myself, but if you've been having similar wonderings, then may this help you too ;)
