I had a “Tilquin Quetsche” bottle pour recently at Hops & Pie in Denver, CO. It was listed as 5.8% and described as:
“Unfiltered, Unpasteurized & 100% bottle conditioned Ale Re-fermented in Oak Barrels with Raspberries”.
None of their beer is listed at 5.8% and none of their Quetsche beers have raspberries (as far as I know).
What beer was this? Or was this a misprint?
