Saving Money: Simple Yeast Culturing Part II



The tools you will need.
I realize it's been a couple of months since I posted actual brewing advice. Today that all changes with another installment on yeast culturing.

Back in June, I wrote a blog on a Simple Yeast Culturing technique that allows you to reuse yeast from previous batches of beer. The simple method I presented required that you re-pitch the yeast within a month or so of cultivating it. But what happens if you wait longer to reuse? Well, you have to do a little extra work to bring the yeast out of hibernation.

Rousing older yeast isn't terribly complicated. Before pitching your hibernating yeast into a new batch of beer, you have to get it going the day before with a starter made from fresh, sterile wort. Here's a rundown of the procedure:
Yeast joins the fresh Wort.
  1. Mix 1/4-1/3 cup of DME (Dry Malt Extract) with 2 cups of water.
  2. Boil the mixture for 10-15 minutes to sterilize.
  3. Cool the fresh wort to 70F.
  4. Pour the wort into a sterilized container (a growler works great for this).
  5. Pitch the hibernating yeast into the cooled wort.
  6. Cover the container with sterilized aluminum foil and leave it out at room temperature.
  7. Swirl the liquid occasionally to keep oxygen flowing to the yeast.
  8. After 24 hours or so, the starter will be bubbling and ready to pitch into a fresh batch of beer.
Waiting for the magic to start.
Are there more scientific ways of doing this? Yep. Plus, there are lots of excellent guides out there if full-on yeast culturing sparks your interest. But for simply getting your old yeast going, this method works beautifully.

Out of the Bottle: Insert clever use of the word Wit here

My latest Wit was a hit at my friend's birthday party. He especially liked the beer's citrus components. Others found it to be light and refreshing. I heard no Blue Moon comparisons, which actually made me quite happy. Compared to My Wit's End , this beer is much closer to style. Unmalted Wheat is part of the reason, as there's much less grainy sweetness at work. Instead, the beer is crisp and dry. The bitter orange peel really does its thing. The peel's sharp flavor melds nicely with the sweet orange peel I also used. Coriander pushes the beer's spicy character along. If I were to change anything, it would be to dial it back a notch or two. Some light sourdough aromas round out the flavor and aroma. Despite the relatively low ABV of right around 5.0%, the beer sports a fairly hefty body. Overall, I'm quite happy with this Wit. Next time, I'll hold back on the coriander. Maybe I will even take a shot at a Turbid Mash, which sounds like a great sub...

Birthday Brewing: Dark Session Saison

I've been asked to brew all of the beer for my friend's Birthday. It's in mid-August, so I have to get everything going right now . There will be five beers in all: Dunkelweiss, Wit, Saison, Dark Saison and Kölsch. Rather than post all of the recipes at once, I'm going to spread them out into separate posts. My Session Saison and SMaSH Kölsch were already underway before I was asked to brew the other beers. The Dark Saison below is an extension of the Session Saison. I've expanded the original recipe to make a darker beer. CaraMunich Malt adds a little caramel sweetness, while Carafa II brings a light dark chocolate edge to the brew. The rest of the beer is as it was before, with the same hops and yeast. Adding extra grains does push the alcohol content up a bit, but the beer still shouldn't break the 5% ABV mark. I'm anxious to try my two Saisons out side by side and taste the difference that two extra grains can make. For five gallons: Grai...

In the Fermentor: Wood Aged Quadrupel-Imperial-Doppel-Barley-Weizen-Wee-Sour

Who says you can't have everything? Well, I'm doing just that by creating a beer that combines the best aspects of eight big beer styles: Quadrupel, Imperial Stout, Doppelbock, Barleywine, Weizenbock and Wee Heavy. But wait, there's more! The beer will be aged for year with everyone's favorite bacterias to make a Sour. On top of that, Sherry infused oak cubes will provide that little extra something. A massive grain-bill, plus a healthy dollop of Candi Sugar should push the alcohol content up over 11%. Compensating for the strength is a biting combination of Noble, English and American hops. A Decoction Mash gives the beer an extra bit of German character. Heavily caramelizing the First Runnings provides more depth of flavor than a standard boil. For that extra push over the cliff, 11 malts are working to make the beer one louder. I'm giving this one at least a year of fermentation before I even touch it. Here's the five gallon recipe: Grains: 4 ...
