Exercise 3 - solution

Paper vs permanent filters:
- Body: paper gives clear, light-bodied coffee; permanent filters do not normally remove oils and essences, so the cup is fuller.
- Oils: paper traps them; metal, nylon or porcelain mesh does not.
- Upkeep: paper is thrown away with the grounds; permanent filters cut cost and waste but need cleaning.

Model pour-over plan (example): Rinse and set up the filter, add medium-fine grounds (chapter 5). Pour a little hot water to bloom for 30 to 45 seconds (from the chapter). Then pour slowly in a circle (from the chapter). Ratio about 15-18:1 (chapter 6; the drip article gives none). Water temperature near 93-96 C (guess, borrowed from the press recipe; check). Total time about 3 minutes (guess; check).
