I had every intention of making a pumpkin beer in a couple weeks, after pipelining some simple, small SMaSH Pale Ales to feature Cluster and Styrian Celeja hops in two otherwise identical brews. I had even toasted up 8 ounces of malt to a nice, nutty, medium toast, to be divided up between the two pale ales. I had even made up 8 ounces of a home-roasted caramel malt, made from soaking grain and caramelizing it in the oven and then roasting it to dry it out. I had done these things for Pale Ales.
The gods of homebrew hurled my butternut squash upon the ground. It cracked at the top, splitting evenly down the center, and halfway down the fruit.
Immediately, I roasted the squash to make some use out of it. If I had left it alone, it would have just rotted like that.
So... That was not part of our dinner plans, just yet.
Beer gods demanded Butternut Squash Beer.
Interesting fact: Most homebrewers who make pumpkin beer are probably already making butternut squash beer, because most commercial cans of pumpkin puree are actually a type of butternut squash, or a hybrid variety of squash/pumpkin called Dickenson Field Squash. Actual pumpkin, if you made it into a pie, would be a golden yellow color, not the orange we know and assume means pumpkin. Butternut Squash is what people are really thinking about, when they're imagining the flavor of pumpkin in their mind. It's richer, deeper, with a bright orange color, and it's a perfect thing to make beer with on an early autumn day!
I cobbled together a recipe with what I had lying around. Fortunately, I did have some more interesting malts in the brewcloset. (Plus some fresh spices straight from Grenada courtesy of my wife, whose family harvest cocoa, cinnamon, and amazing nutmeg and send it to us from their farm. Nutmeg and cinnamon were both from Grenada!)
This batch turned into a 3 gallon brew when I lost track of how much water I was pouring into the darn brew kettle... The end result was around 3 gallons, right?
I pulled up my edition of iBrewmaster...
BUTTERNUT STOUT!
3 gallons, thereabouts
OG: 1.062
FG: 1.017
30 SRM
(estimated mash efficiency of 86%)
3 pounds of Rahr 2-Row Pale
1 pound of Munich Malt
8 ounces of home-toasted malt
8 ounces of home-made caramel malt, est. at 100L-140L
6 ounces of Caraffa I
6 ounces of Dark Brown Sugar, added to the boil
half of a roasted butternut Squash for about 1.5 pounds, pureed
@60 minutes use 1 ounce of Cluster hops for about 40 IBU
@15 minutes, add one small cinnamon stick, 1/2 tsp of fresh-ground Nutmeg, .25 ounces of grated, fresh Ginger
Include in the full Primary (or secondary instead, if you plan to use one) with 1/4 of the cooked, pureed butternut squash
Pitch 1 full packet of Safale S-04
With Brew-in-a-bag, and a very fine grind, I'm expecting a super efficiency. I also did another overnight mash. In fact, my overnight mash went long because I got pulled away for some stuff for work in the morning, and could not get to the wort after eight hours. It was a thirteen-hour mash, then. I set the oven to 180 degrees when my wort, on the stovetop, was protein resting at 122 degrees for twenty minutes. By the time I got the wort to 154 degrees, the oven had reached 180 degrees. I put my kettle inside to mash overnight, and flipped the oven off. When I woke up, before I got an e-mail from work, I had flipped the oven back on to buy someself some more time, to 200 degrees. I had started the mash at ten o'clock, and didn't mash-out until almost eleven-fifteen.
And, my grind was very small, too. I was really aiming to pulverize this stuff, because I wanted to give BIAB a real go of it with a finer grind.
Anyway, woot for butternut squash! There's still a quarter of the squash sitting in the fridge for my wife.
Of note:
The squash that I put into the primary fermenter was microwaved just before putting it into the primary good and long, to make sure it was completely cooked and to make sure it was completely sanitary. It seemed like the easiest way to sanitize something that likes being cooked in a microwave, right?
Of note: Pictures of a brewday that was messy and spontaneous and fun.
The smell in the primary, just before pitching, was stunning. A milder dark roast, with Caraffa I instead of chocolate and medium-toasted malts instead of dark roasted malts, may not be the "perfect to style" stout, but it does ease into the stout flavors, allowing the butternut pie flavor with the sweetness of the caramel malts, to shine over the top of the dark, thick brew!
It's the sort of thing that makes me want to use exclamation points. Because the squash fell! I can make it into beer! The beer smells really good! Everything is working!
BUTTERNUT STOUT!
