As the name suggests, Pêche Mel' Bush (Pêche Mel Scaldis) is a marriage between Bush Ambrée, perhaps the strongest of Belgian beers, and ripe peach juice. Allegedly it was students who came up with the concept (and the name): they mixed a 'beer cocktail' that was a simple blend of Bush Ambrée and a peach-based geuze.
Dubuisson adopted the idea, but their take on Bush-plus-peaches makes use of their own recipe, involving a heavy dosing of Bush Ambrée with natural peach extracts. The brewery introduced Pêche Mel Bush in 2009. With an ABV of 8.5% the brewery puts in a good claim for having the 'strongest fruit-flavoured beer' in Belgium.
