Every “nailed it” sharpens the starting recipe for your exact setup — your next bag starts even closer. Enjoy the cup.

Tip: a second bag in the same order ships with the same free-shipping love.

Sour or weak — here’s the move.

• Grind one step finer. Sour usually means the water ran through too fast.
• Or go hotter. A few degrees up rounds out sharp edges.
• Espresso: if the shot runs under ~20 seconds, finer grind — keep the dose the same.

Change one thing, brew one cup. Still off? Stefan will dial it with you:

Bitter — here’s the move.

• Grind one step coarser. Bitter usually means over-extraction.
• Or go cooler. Drop the water a few degrees.
• Espresso: if the shot drags past ~35 seconds, coarser grind.

Watery or flat — here’s the move.

• Tighten the ratio. Try 1:15 instead of 1:16 (a bit more coffee).
• Grind finer or extend the brew ~30 seconds.
• Check freshness of the grind — grind right before brewing if you can.
