My steam hefeweizen is still in the primary, happily fermenting away. Fermentation has slowed now, but the krausen hasn't quite fallen, so I will probably give it a couple of weeks yet before I check FG and rack to a keg. I'll be sure to say how it turned out. But this was my first hefeweizen, first steam infusion mash, and first 5 gallon AG batch, so I don't really have anything to compare it to for quality!
It was REALLY easy to do the mutistep mash, though. I did a protein rest and a mash-out at the end, which I had never done before. All I did was open the steam valve and stir every now and then -- foolproof! (Perfect for me!)
