Most fruit has natural bacteria on it's skin. If you add it with no preparation, you risk an infection. Due to the alcohol in the beer, any infection will take months to show itself. However, it is a gamble, and you might be OK. The beer has alcohol, which will prevent many potential infectious bacteria from reproducing.
Adding fruit to the boil will cause pectin haze in the beer. It will also cause a lot of the volatiles (aromas) to evaporate either during the boil, or during the initial fermentation.
What should you do?!?
- You can freeze fruit. The freezing action will kill most yeasts and bacteria. You can add the fruit straight from the freezer.
- You can pasteurize the fruit. Heat in a little water yo about 145 F and hold for 20 minutes.
