Your coffee nostr:nprofile1qqsph3c2q9yt8uckmgelu0yf7glruudvfluesqn7cuftjpwdynm2gygpz3mhxue69uhhyetvv9ujuerpd46hxtnfduq3qamnwvaz7tmwdaehgu3wwa5kuegpzpmhxue69uhkummnw3ezumrpdejqwk5cd9 your rules, but my advice don't do drip, burns the coffee doesn't do full extraction, pour over or French press would be my picks.

In general light roast more flavours, i like City roast, darker roast usually disguise shitty coffee, but again is your taste that matters
