A friend asked my opinion on this recipe. I have never made a Dunkel, so I thought I would send it out for feedback.

Any suggestions on mash schedule, and fermentation temps?

TIA

I'm no expert, but don't you need some 2-row or somehting in there for an enzyme source?

1. Double decoction, 50-60-70C.

2. 68F.

Also, you are pushing the envelope on the wheat malt percentage, rice hulls are a must (at least if I were brewing this).

Wheat malt and munich/vienna malt have enough enzymes to convert themselves. No grain adjuncts, no need for two row.

Ben, all those malts can easily convert themselves, so no worries about enzymes.

This sin't a style I brew, but I generally see recipes for it that have a lot more Munich. Comments, anyone?
LIfe begins at 60...1.060, that is.

Well, this recipe wouldn't be an "Imperial Dunkelweizen", and the 74% wheat seems to be at the limit for this, but it would look to make a pretty good dunkelweizen, IMHO. If its Erdinger weizen you're aiming for, it should be in the ballpark. Schneider Aventinus Weizenbock it ain't.

Thanks for all of the input. After reviewing all of your comments and doing a little research this is what I came up with. Basically I just increased the Munich from 1# to 3# and decided to use the unused portion of the hops (1/4 oz) as FWH. The OG is now up to 1.073, which should make it Imperial.
