Cuvée Freddy Bosbes from Brouwerij Alvinne is a complex sour ale at 8% ABV, aged in red wine barrels and macerated with blueberries. This amber-hued beer marries the characteristic acidity of Alvinne's proprietary Morpheus yeast with the elegant tannins and subtle warmth imparted by oak. The result is a rich, fruited sour layered with blueberry, red wine and dark fruit complexity.

The taste unfolds in stages: initially tart and sour, followed by notes of blueberry skin, cherry and vinous character. Woody and earthy undertones provide structure, while a hint of caramel offers balance. Medium-bodied with soft carbonation, this is an elegant, nuanced beer that honours the Flemish sour ale tradition.
