The beer is so tartly thirst-cutting that Germans calm it with raspberry juice or essence of woodruff. The city's Kindl brewery sends not only its Berliner Weisse beer but also the sweetening syrups to soothe the thirsts of America. These, too, are sharply refreshing, with a taste that reminds some drinkers of passion-fruit. Belgians sometimes sweeten them with grenadine, but connoisseurs prefer them straight. The best known example, available in the U.S, is Rodenbach.
Wheat beers are different in Belgium.
They are flavoured with Curacao orange peels and ground coriander seeds. One of the best I have tasted is actually made in the U.S., by the Brooklyn Brewery. It's called Blanche de Brooklyn. Crisp, dry, and deliciously drinkable. There is nothing more obviously summery that a fruit beer.
