Check-in: Partigyle Pumpkin Barleywine

Based on my blog stats, it appears that you all have enjoyed my post on partigyle brewing. Or, at least, wondered what the hell it was. In fact, that post has narrowly edged out my post on Adam's Vienna Lager con Agave y Limon for page views. I greatly appreciate all the page views, but I would appreciate comments even more. Just sayin'. Anyway, because of the popularity of the partigyle post, I decided to do a check-in on the pumpkin barleywine.

About 3-4 days after pitching SafAle US-05 to the initial 3 gallons of wort, I added the washed yeast cake of White Labs WLP099 Super High Gravity Ale yeast from Golem pale ale along with 1 lb. table sugar. Since adding the WLP099, I've added another pound of sugar every 2 days or so. Tonight, I took a gravity reading before adding the 4th pound of sugar. After adjusting for the water in the sugar syrup, the OG calculated to 1.123. My hydrometer read 1.013 for an estimated ABV of 14.5%! This is higher than I've ever gone before, as a previous beer (A Russian Imperial Stout) pushed just over 13% ABV. However, this barleywine has a bit further to go. This yeast is purported to tolerate up to ~25% ABV under the right conditions, so my goal is to try to push 20%. That means I'll be adding a total of around 6 lbs. of sugar. We'll see if this yeast conks out before that. I hope not, since it already tastes like bitter rocket fuel. At least one gallon of finished barleywine will get racked atop Jack Daniels bourbon barrel smoking chips. There maybe other weird and wild variations as well. Stay tuned! Who knows? Cheers!


Check out my gravity reading. Beersmith estimated 1.023. So much for that!

A Beer Without A Soul

When I set out to brew the epic partigyle batch described a few posts ago, I knew that the big beer--the barleywine--would require some special treatment. The White Labs WLP099 yeast I was planning to use to ferment this beer can tolerate up to 25% ABV and attenuate >80%. It is also a somewhat finicky yeast, requiring up to 4Xs the amount of yeast as a normal beer to chew through that much sugar. White Labs also recommends using multiple yeast nutrient additions, staggered additions of wort (I'm doing sugar additions), and regular aeration/oxygenation. I could manage yeast nutrient and aeration, but propagating that much yeast would be difficult. So, instead of stepping up a yeast starter multiple times or buying several vials of yeast (at $6.50/vial), I decided to ferment a starter beer (5 gallon batch), harvest and wash the resulting yeast cake, and use that in the barleywine. Such a strategy is often used when a homebrewer wants to pitch plenty of yeast in a high gravity beer.
Since the only purpose of this "starter" beer was to create massive numbers of viable yeast cells, it did not particularly matter what was in it. I decided to use up some bits of malt and old homegrown hops to make an English Pale Ale. As such, the beer did not really have a central theme or unifying principle. It was, essentially, soul-less, and it's flavor experience follows suit. Although my heart was not in this beer, that doesn't mean I missed out on a learning experience. I learned about using old hops, about a hop variety I haven't used before (Pacific Gem), and some of the characteristics of WLP099. The following is the beer's recipe and a tasting.

Recipe: Golem Pale Ale; 5 gallons; OG 1.060; ABV 7.2%

Grist:
10# US 2-Row Pale Malt  80%
1.5# Quick Grits  12%
1# Bairds Carastan Malt  8%

Hops:
1 oz. homegrown Nugget @ 90 min. (first wort hop)
1.75 oz homegrown Nugget @ 5 min.
.5 oz. homegrown Nugget (Dry Hop 7 days)
1 oz. Pacific Gem pellets (Dry Hop 7 days)

Other additions:
1 tsp. Irish Moss @ 15 min. boil
5g Gypsum (Calcium Sulfate) Mash 60 min. 

Yeast:
White Labs WLP099 Super High Gravity Ale yeast

Instructions:
Single infusion mash @ 152F for 60 min. Mash-out @ 168F for 10 min. Add Carastan malt after mashout and before Vorlauf/sparging. Boil down first gallon from mash tun by half (or more) for more color/flavor from grain. Add to last 5 min. of boil. Add 5 min. hop charge at flameout; simulate whirlpool by stirring hot wort for 20-30 min before further cooling 

Tasting:

A-Pours rather clear for a low flocculating yeast. A dark straw, pale orange, it looks a bit thin in the glass. Minimal head which lingers as a white ring around the edge of the glass. Small bubbles continue to stream endlessly upwards. A picture of lifeless, shallow beauty.

S-Muted berry and subtle oak. Some acetone and fusel alcohol underlies the fruit and oak. Smells reminiscent of berry jam.

M-medium bodied, carbonic sharpness, hint of hot-ness in the throat

T-grassy hops mixed with muted berry, carbonic bite, fruity yeast esters, acetone

Overall-I brewed it, so I will drink it. If I brewed this again, I would use fresh hops and a different yeast. Perhaps, if you decide to brew this or a similar beer, you can help it find a soul, but keep watch lest it ravage yours. Let me know how it goes. Many thanks. 

Cheers!

Until next time, BE FERMENTIVE!
