To brew this beer and to really get the maximum expression of flavors, you have to step mash. And since we do not have a big fancy electric system capable of step mashing 10 gallons of beer at a time at full water volume... we have to do infusion step mashing.
So my advice, learn about step mashing. Learn the sciency stuff. If you want to make world class Belgian beers this is the key.
UPDATE: The BDSA is as we expected it to be. It is delicious. But we are getting adventurous and with 5 gallons, we are adding bourbon soaked oak chips, and bourbon soaked cherries. That should be pretty fantastic. We will keep you posted.
