Belgian Quadruple | Meditation 32

Brew date: Sept. 18, 2015
#42 - 6 gal

I often find brewing to be a meditative experience. Spending the day outside, just enjoying the process and taking in the natural scene from my driveway. Apples quietly dropping from our tree. Birds chirping. The occasional passerby. Peaceful. A great way to kick off my birthday weekend and the perfect setting for this beer.

I've wanted to brew a Belgian quadruple ever since my first taste in 2007 at Brasserie V in Madison -- a great place for discovering Belgian and other European beers. The recipe is loosely inspired by several that I found, including clones for St. Bernardus Abt 12 and Westvleteren 12.

Brewing this batch did come with difficulties. The week leading up to brew day, I dutifully made a yeast starter, but to little visible effect. After a couple of days, I purchased another White Labs vial and added it to the starter, again with seemingly little effect. Finally, I pitched a pack of Wyeast 3787 Trappist yeast directly to the wort. It's now fermenting away, but I'm still not sure if that's due to the White Labs starter or the Wyeast pack.

Moreover, a hose slipped at the end of chilling and whirlpooling, causing a loss of almost a gallon of wort. Extremely unmeditative. I need to start using clamps to keep the hose in place.
