The closest thing that I can think of to that concoction that has proven palatable is the Leinenkugle Berry Weiss beer. I first encountered that particular brew at a nice minor league ball park in one of our suburbs where Leinie is one of the sponsors and is served cold and in large cups for a reasonable price (remember that a beer at US Cellular Field, home of the White Sox, is now $6.25). Anyway, the Berry Weiss and it's Lemon Weiss brother are great for a hot summer day. When i first tasted it I immediately said "Shandy!" and all of the folks around me had no idea what I was talking about.

Apparently, this Panache thing requires that genuine French bottle lemonade.

Best
