there are a LOT of dark malts in there. was it black? magnum seems a little strange for a weizen, too. as long as it came out good!
i try to use tettnanger whenever possible for my wheat beers. i've only got 2.25 ounces left, tho
maybe i can get some rhizomes this year...i need to at least save some for the summer so i can make an AG version of my american "hoppy" hefeweizen.
i usually regulate my temp to the low 60s, too. i'm not worrying so much for this one...looks like it's going to be in the 68-70 range. a little more banana, probably...we'll see how this yeast takes care of it.
