strange - I never woulda thought about hoppy with Hennepin. sounds like marketing term du jour as opposed to reality.
Hennepin is meh, in my book. Lagunitas Farmhouse Ale is a bit better, but I do not pretend to know that style well.
Ommegang's Witte is fantastic though - odd to spend 6 bucks on a bomber of it when you can make 12gal of tasty wit for less than $40 (including all propane, etc costs). but it is a GREAT representation of the style. Don't let Hennepin turn you off of them.
