Fresh brewed coffee often pours at 160–185°F (71–85°C), hot enough to scald; cooling 3–5 minutes brings it nearer sip range.

French press coffee needs a coarse, breadcrumb-like grind so the mesh filters cleanly and the cup stays smooth.

For a cafetiere, grind coffee coarse like sea salt so it steeps 4 minutes, tastes sweet, and leaves less grit in the mug.

After caffeine, breastfeeding is usually fine; feed first, then wait 1–2 hours, since milk caffeine peaks near 1 hour.

200 mg of caffeine usually feels active for 4–6 hours, and smaller effects can linger close to 10 hours.

Most people sleep better if they stop drinking caffeinated tea 2–4 hours before bed, and earlier if they’re sensitive to caffeine.

Espresso grind is fine like table salt, set so a 1:2 shot runs 25–30 seconds; go finer if it gushes, coarser if it chokes.

Coffee grounds should be finer for espresso and coarser for cold brew, with drip and pour-over in the middle.

Breastfeeding after caffeine is often fine right away, and waiting 1–2 hours after a drink lowers the caffeine level in milk.

200 mg of caffeine can delay sleep for 6–10 hours, and some people still feel it into the next day.
