Jolly Pumpkin Experimental Batch
For my next batch I decided to venture into the world of culturing up yeast from the bottle of a non-filtered commerical beer. I figured what better yeast to culture then the house strain from Jolly Pumpkin (if they really even have one specific house strain). I have always loved the aroma and flavor their yeast provides the Noel de Calabaza so I decided to use the dregs from two bottles of that beer to get this one going. I started the processing of growing up the yeast about a month ago and I'm at the point where I have a really healthy batch of yeast. I'm sure the character of the yeast and ratio of regular "Belgian yeast" to wild yeast has change over the course of building this starter up but it's still smelling and tasting great. If you are wondering what the heck I'm talking about take a look at this article. I can't wait to get this beer brewed and in bottles. Here is the recipe.
5 Gallon Batch
Brew Day = 09 Jan 2010
6 lbs of German Pilsner Malt
4 lbs of American two row
1.5 lb of raw wheat
.5 lb Barley (Flaked)
.25 Crystal 80
60 Minute – 0.5 oz of Nelson Sauvin (11.5 AA)
30 Minute – 0.5 oz of Simcoe
KO – 1 oz of Centennial and 1 oz of Amarillo
Dry – 1 oz of Centennial and 1 oz of Amarillo
Used the dregs from a 2007 Jolly Pumpkin Noel de Calabaza bottle. Did an initial starter on the 2007 bottle and then a second step up and added the dregs from the 2009 bottle. Grew it up 4 times and then will do a starter before using.
Pre-Boil Gravity = 1.041
OG = 1.057
FG = 1.012
ABV = 5.8%
IBU = 32
Mash at 149 degrees F with 3.8 gallons of water
90 Minute Boil
I'm still tossing around the idea of adding some fruit to the secondary or maybe even some honey and letting it sit in the secondary fermentor for a month or two. Does anyone have any thoughts on that? I know the Jolly Pumpkin culture has some brett and other wild yeast in it and want to make sure some of that character comes through. Although I'm also dosing this with a nice aroma addition of some American hops. Basically this recipe is roughly based on Jolly Pumpkins Bam Bier. Open to suggestions. Let it take it's course of a regular 3 week fermentation. Or let it sit through a longer secondary process and introduce some fruit and/or honey into the secondary?
