Imperial Vanilla Milk Stout Recipe
Posted on September 8, 2012
Big stouts and vanilla is a natural pair. Add a touch of creamy sweetness, and you’ve got a winner. This recipe has a luscious mouth feel from the flaked barley and crystal malts, smooth roast flavors of coffee and chocolate, subtle dark fruit notes, and a slight sweetness from the lactose. This is a slightly sweet beer, but not nearly as sweet as many commercial sweet stouts.

Water
Carbon-filtered Seattle water which is very soft. All salts added to grist before mashing in.
2 g Epsom Salts (Magnesium Sulfate)
2.0 g Gypsum (Calcium Sulfate)
4.0 g Calcium Chloride (Calcium Chloride)
4.0 g Baking Soda ()
Mash
60 Minute Saccharification Rest at 152° F
10 Minute Mashout Rest at 170° F
(I do a second hot water infusion to mashout)
Sparge at 170° F and collect sufficient runnings to hit pre-boil volumes.
Fermentation
- Chill wort to 64° F and pitch yeast slurry.
- Set temp controller to 66° F and allow to rise to this temp.
- Ferment at 66-68° F until beer is 2-6 points from terminal gravity then raise temp to 72° F. Hold at 72° F for 2 days.
- Chill fermenter to 34° F. Rack beer off yeast into clean container with bourbon soaked vanilla beans (include the bourbon as well).
- Age 1 month on vanilla beans before packaging.
Keys to Brewing
- Controlling fermentation temperatures and pitching a clean healthy yeast slurry is important in preventing hot alcohols in this beer that would distract from its rich, smooth qualities.
- Use fresh high-quality vanilla beans. If they look dried out, they are probably old and shouldn’t be used. Beans should be sticky, almost tacky to the touch. I’d recommend sourcing these online from specific vanilla retailers who move a lot of beans (as opposed to the ones that may languish for months in the homebrew shop).
Whoops think I may have doubled up on the roast barley !! when doubling the receipe
