Rodenbach is a sour ale blend of 1/4 aged "mother beer" - which has matured in oak at least two years - with 3/4 of a younger, sweeter counterpart. A great introduction to the Flemish sour ale style, the brew pours a hazy brown color with auburn highlights and a small beige head. Aromas include sour cherry, vinegar, dark berry, green apple and grape with notes of sour candy, caramel and coffee.
