* If aging sour beer on whole fruit, use a punch-down tool frequently so that the low pH kills any mold that might be present before it begins to grow. CO2 CO² may be helping the fruit to float, and punching-down the fruit will help to release that CO2CO². Homebrewers can gently swirl their carboys to accomplish the same thing. Purging the headspace with CO² will also help prevent mold growth.
