Raspberry lambic was once a rarity and only produced for a few weeks during the summer. Frank Boon was the first brewer to again prepare a raspberry lambic in the summer of 1976. More than 300 grams per litre of fresh raspberries give Framboise Boon a fresh fruity taste. The young lambic supports the flavour. But this is very much about raspberries, not the lambic. Of course we do not use artificial flavourings, only real raspberries.
