“Green Walnut” is a surprising and innovative Lambic beer of Oud Beersel. For the production of the Green Walnut real fruit is used, in the same way as for the Oude Kriek of Oud Beersel. In July the still green walnuts are gathered in the Oud Beersel orchard and are added to the Lambic beer that matured in wooden wine barrels. After the bottle fermentation this sparkling walnut Lambic of Oud Beersel is called Green Walnut, which is a strong companion for blue-veined cheese, dried ham and salads with nuts.
