Was hoping to find time to make this one today, but time's getting away from me, and triple decoction (+ decoction mash-out) can take some time. From BeerSmith:

NOTE: This brew meets most of the criteria for the Weizenbock style, except for colour. I figure if you can have a Maibock as a pale bock, why cannot a similar wheat bock exist?
Maybe Tuesday while I get a rego check and tune-up (for the car, not me...or the brew-rig).
I have assumed the same evap rate as my old BBQ burner (which will be wrong), and have also (upon recommendation) assumed a reduction of AA% to 1.8 for my hops. I will sparge more (volume) and hope for a higher extract efficiency.
Will be a good chance to test the Chinese spiral burner (with stand). Have borrowed an adjustable HP reg from MHB. Seems pretty good, and I'm scared to give it full bickies. I put the 80 litre s/s keg-like pot on, with 30l water and it's up to boil in about 20 min (or less), from tap temp. If it turn up the burner valve too much, the flame reflects off the pot and goes under the ring and is likely to burn my back verandah, despite being raised on bricks, too. Burner cost - $30. Two thumbs up!
