Adding flavor on the cold side can be fun and adds a whole new dynamic to your beer. Warning though, since this isn’t part of the natural brewing process these processes open the door to contamination. Great care must be taken in sanitation and preparation to ensure product quality is maintained.
Adding Fruit: There are about four ways to add fruit to your beer.
Fresh fruit; first clean it thoroughly, then freeze it and grind it up (Freezing helps lower the microbial count and breaks down the cell walls).
