The most obvious fruit and beer combination is witbiers and oranges. Witbiers incorporate orange peels in the brewing process giving it a predominant citrus flavour that is enhanced when paired with oranges. The high levels of malt in the wheat used in witbiers cuts through the strong acidity in oranges.
Apples are best paired with a brown ale. The sweet juice and grainy texture of apples compare well with the malty sweetness of the beer. Caramel and apples have always been a winning combination, making the caramel notes in brown ales a perfect match for apples.
Although fruit is generally light in flavour and should be paired with a lighter beer like a pilsner, strawberries are one of the stronger fruits and pair best with a stout. The taste of strawberry lasts long on the palette so it is important to match it with a beer that does the same, like a stout. Stouts also have subtle hints of chocolate making it a great pair with strawberries.
Fruit and beer can make a surprisingly tasty combination. Many beers contain traces of fruit which makes it a good match. Other subtle undertones in some beers compare and contrast nicely with the different flavours of fruit.
