I moved my Bitter from primary to secondary (P.G. 1.014) and reused the yeast cake on a flaked barley stout. The stout used a mass of grain that might have been a bit excessive, but the wort tasted pretty good and the O.G. was 1.054.

The bitter is quite mild and carbonation will probably make it a rather delicate beer. Delicate hop wise 🙂

Yeast washing is another way to harvest yeast from one batch of beer to use in another batch. This is a great way to save some money on brewing costs. The benefit over simply reusing a yeast cake from a batch is that you don’t have any of the trub, or nasty proteins, hop particles and gunk that settles to the bottom during primary fermentation. With yeast washing, you get just a healthy sample of yeast without any of that extra sluff.

Ironically, the idea for this came from Wyeast Labs, an Oregon laboratory that sells brewing yeast. Instead of rewriting their recommendation on how to wash yeast, I’m simply going to link to it.

Yeast Washing for the Home Brewer

There’s also an interesting article on acid washing yeast to remove extra gunk and hopefully improve fermentation. I’m going to stick with simple washing for now.

Yeast can be one of the most expensive parts of brewing. If you’re hooked on liquid yeast like me, the $5 a tube is about a third of the price of a batch. As much as I enjoy the work of the folks at the two major liquid yeast producers, I’d like to cut down on the amount I spend on yeast. I’m going to be writing about 3 easy ways of accomplishing this starting with the simplest: Reusing the yeast cake.

This is as simple as it sounds, and works quite well. Of course, you need to time the process so you’re done with primary fermentation on one batch at the same time as you brew. Here’s the basic idea. Beer 1 is ready to move from primary fermentation to secondary. Beer 2 has just cooled after brewing. Siphon Beer 1 into a sanitized vessel for secondary leaving as much of the sediment behind as possible.

Assuming Beer 1 smells ok, siphon Beer 2 directly on to the leftover yeast cake and trub. You might want to gently stir the beer to get some of the yeast into suspension. With any luck, Beer 2 will start fermenting quickly.

Considerations

• Any strong flavor or color from Beer 1 might manifest itself in Beer 2, so don’t brew an imperial stout and reuse the yeast cake for a kolsch.
• Be aware of any odd smells. If the yeast is bad or infected, reconsider using the cake.
• There will be all sorts of undesirable gunk left over from Beer 1. If this worries you, consider washing the yeast.
• Don’t use the yeast cake too many times. Yeast will mutate and its hard to know how your beer will taste

I bought a vacuum sealer yesterday so I could cut and bag my fresh hops without sacrificing their freshness to the freezer. The sealer I bought worked like a charm, and did an awesome job of compressing the hop packages. The most impressive part was how quickly I was able to slice up the 5 packages of hops and seal them in brewing quantities for later.

I smelled quite a few varieties last night, and Crystal was by far my favorite of the bunch. The aroma was stellar – citrus and pitch. I can’t wait to brew something special with them.

Today I brewed with an ounce of Galena for bittering and 2.2 oz of Fresh UK East Kent Goldings. I brewed a fairly traditional special bitter and used munich and British pale malt for flavor. The brew supply store didn’t have any Maris Otter.

I’ve added two new(er) recipes. Both should highlight the UK East Kent Golding’s that I got from my father-in-law for Christmas. One is Andy’s Special Bitter (ASB), the other Flaked Barley Stout.

For cost savings, I’m going to reuse the yeast cake. Naturally, I’ll be brewing the bitter first. Otherwise I might color and/or flavor pollute the bitter.
