Kasteel Rouge 0.0 is an alcohol-free Belgian cherry fruit beer, made in the specialty style. It is brewed without alcohol rather than blended from a base, so it drinks as a beer in its own right. The aroma leads with cherries and a touch of elderflower. To taste it is sweet and smooth, with dark cherry, soft malt and a faint berry edge, while a mild acidity leaves it slightly tart and refreshing. It is deep ruby red in the glass with a soft, creamy head and only a gentle fizz. The finish is balanced, clean and fruity, ending on a slightly sweet aftertaste.
