Here’s your friendly crash course from bean to cup. We start at origin: Arabica brings nuance and sweetness; Robusta’s bolder, higher in caffeine, and more bitter. Processing shapes flavor—washed = clean/bright, natural = fruity/wild, honey = in‑between. Roast levels? Light highlights origin, medium balances, dark leans roasty and bittersweet.

Buy fresh (look for a roast date). Single-origin for distinct notes; blends for consistency. Store beans airtight, opaque, cool, and dry—away from heat, light, and oxygen. Not finishing the bag soon? Freeze in airtight portions and thaw sealed to avoid condensation.

Gear matters: a burr grinder beats a blade every time; use a scale. Water makes up most of your coffee—clean and filtered is best. Brew around 195–205°F (90–96°C). Match grind to method: espresso fine; AeroPress fine–medium; pour‑over medium‑fine; drip medium; French press/cold brew coarse.

Start with 1:15–1:17 (coffee:water) for pour‑over/drip; espresso about 1:2 by weight. Bloom fresh grounds, then pour steady. Taste and tweak: sour/thin = under‑extracted (grind finer or brew longer); bitter/astringent = over‑extracted (grind coarser or brew shorter). Steaming milk? Aim for silky microfoam around 130–150°F.

Clean your gear, keep notes, stay curious. That’s the whole delicious adventure.
