Barista Champion Debunks Mold Fears, Focuses on Carafe and Water Quality
Heather Perry, a two-time U.S. Barista Champion and CEO of Klatch Coffee, advises home brewers that mold fears are largely unfounded. She emphasizes that the carafe, not the water reservoir, is the primary area for flavor-affecting residue. Perry recommends using filtered water with minerals, wiping grinders to remove oils, and storing coffee in the freezer rather than the fridge to maintain freshness.
