Huh, that's interesting. I have one beer I brew all the time and ferment it at 24C, which is a bit above 73F, and I get mostly phenolics like a Wit-bier. If I rehydrate the pack I don't get very much of anything.. Sort of just slight this and slight that.
My experience had lead me to believe that mash regimen / grain bill has much to do with the flavors of a good Bavarian style hefe. And either way, it's something I love about this hobby -- so much diversity of outcome. Cheers!
