Brewing a better cup at home
Four things that matter more than the machine: water, grind, ratio and time.
Water
Filtered, just off the boil. Coffee is 98% water; taste yours first.
Grind
Grind just before brewing. A burr grinder, even a hand one, beats any blade.
Ratio
Start at 1:16 — 15 g of coffee to 240 g of water — and adjust to taste.
Time
For a pour-over, aim for three minutes. Faster is thin, slower is bitter.
