This course of is called oxidation, says Bucknavage, and can create sure “off” flavors.
Bucknavage provides that yeast, lactic acid micro organism, and different spoilage micro organism can develop the longer that chilly brew espresso sits, which might trigger it to bitter and ferment like alcohol.
