Tips for Better Coffee

Water quality matters. Use filtered water — chlorine and minerals affect taste significantly. Water should be 195-205°F (90-96°C) for hot brewing. Boiling water scorches coffee.

Grind fresh. Coffee begins losing flavor within 15 minutes of grinding. A burr grinder produces more consistent particle sizes than a blade grinder.

1 tablespoon ≈ 5g of ground coffee. A kitchen scale is the most accurate way to measure, but tablespoons work in a pinch.
