Brewing beers with fruit additions is both fun and delicious, especially as the weather warms and we drag on into summer. But like with any brewing additive, there are many variations and schools of thought on the easiest and best ways to flavor a fruit beer.

Once you’ve chosen a fruit flavor to impart in your beer – choosing the flavor is a different argument for a different day – there are generally three different methods and times you can choose to flavor your beer: during the boil, during the conditioning, or at bottling time. I have used all three with varying results.
Adding fruit during the boil creates the strongest fruit flavors – especially if you use real, fresh or frozen berries – but also requires the most fruit. One hint I found very useful (although much messier) is rather than putting the berries in a muslin bag, add lose berries to the boil so that when you pour from the kettle into your fermenter through a funnel, you essentially create a filter of berries through which the wort has to pass, sucking out even more fruit juice and flavor.

The second option is adding fruit (usually either whole fruit or a puree like those from Oregon Fruit Products) to your secondary and aging/conditioning the beer on a bed of fruit for a few weeks. This requires less fruit volume than adding during the boil and results in a great aroma, but less fruit flavor is absorbed into the beer this way. Of course this is not necessarily a bad thing; it all depends on the presence you would like the fruit to play in your beer. Often it will be a matter of trial and error until you find your preferred method of fruiting.
Lastly, the option which is probably the easiest and most cost effective would be to add a few ounces (to taste) of fruit extract to your bucket just prior to bottling. The main downside to this method, however, is that the resulting flavors can often be very syrupy—like a Seadog Blueberry for a commercial comparison – and not taste authentic enough for most seasoned homebrewers.

Whichever method you choose (and again, I recommend playing with all three), flavoring your beer with fruit is a fun and welcome summer brewing experiment. To take this a step further, try brewing a recipe or a style which would not normally call for fruit, like a Coconut Coffee Stout; or a fruit not normally found in beer, like a Kiwi Wit, and see what happens. Good luck and happy brewing!
