(not yet rated)
Beer Style: Dubbel
Recipe Type: all-grain
Yield: 5 gallons
Description:
Adapted from 'Halo Dubbel' from the October 2003 BYO Trappist Ale article by Horst Dornbusch. Because Trappist Ales are unique from other Ales, it is worth checking out the full article here: byo.com/malt/item/1525-trappist-ale
A few things to note in case you don't want to read the full article cited above. Trappist Ales are usually a simple one step single infusion mash for 90 minutes. The sparge and boil are also usually 90 minutes. They have a unique fermentation process, may use multiple strains of yeast, and are usually bottle conditioned for an extended period of time. You may just want to go ahead and read that article cited above.
As for how we adapted this recipe, the original recipe called for Pale and Crystal malts, all of which are available to the gluten free brewer. We increased the grain and fermentable sugar bill 20% in order to get closer to the 6.6% ABV of the original recipe. For the yeasts, we are substituting the liquid yeasts for the gluten free Mangrove Jack's M41 Belgian Ale and M47 Belgian Abbey dry yeasts. The yeast strains need to be fairly alcohol tolerant, which we did not confirm, so you may want to do a little homework in regards to which yeasts to use.

If you didn't read the original BYO article for any previous sections, you should at minimum read the following excerpt:
"Because Trappist brews have a relatively high starting gravity, it is a good idea for a healthy cell count to pitch two packages of (yeast). Alternatively you can use just one package of yeast and save money by making a yeast starter. Rack the brew off its debris after about two weeks. Then keep it undisturbed for another two to three weeks. Rack the beer again and prime it with sugar. At this point, to aid in bottle conditioning, add the remaining package of yeast. This yeast ought to be fairly alcohol-tolerant. Package immediately after priming and inoculating.
...Keep both your fermentation and your conditioning temperature constant at around 68F. You can start tasting the beer after about a month, but it will get much better after a conditioning rest of about half a year."
