New Season, New Beers

Although the first day of Autumn isn't until September 22^nd this year, most people feel like the start of September is, at least, the start of the end of Summer. Days get shorter and the air is cooler, and when the seasons start to change, so do the drinks we enjoy.

Now there is certainly nothing wrong with drinking a light pale ale during the fall and winter months, but after drinking these over the long hot summer, it is nice to try something new. Here are some styles of beers that you might want to start brewing now for the months ahead:

• Pumpkin Ale – Low alcohol ready for Halloween, High alcohol ready for Thanksgiving

• Christmas/Holiday Ales – Big alcohol needs time for aging just in time for Christmas

• Bock or Dopplebock – Great to lager through Fall/Early Winter

• Scotch Ale – One of my favorite cool weather beers. Small versions can be ready fairly soon, while others will need some age

• Bitters and ESB – Great transitional beers from the big hoppy summer beers

• Rauchbier, Browns, Porters, and Stouts are nice this time of year also.

 Time to get the Imperial Oaked Pumpkin Saison started.

 

Reusing your yeast

Have you ever thought about reusing yeast instead of purchasing more every time you brew beer?

It is a great way to save a little money and get a really good pitch rate, so here are a couple of options to get you started:

The easiest way to reuse the yeast is to just pour your new beer onto a yeast cake from a batch you just moved to secondary. This of course requires you to have a beer ready to ferment at the same time you are ready to move a previous beer to secondary. This technique also creates a HUGE pitch rate, which can actually lead to off flavors, or what can be referred to as being “too clean”, meaning there is no esters at all and makes for a strange flavored ale. Use this technique mainly when lagering, where you need a lot of yeast and are trying for a super clean flavor anyway. A popular use is going from a light lager, such as a pilsner, to a big alcohol lager like a bock or double bock.

The second easiest way is to pour or scoop a quart (or so) of your yeast cake from a finished batch into a growler, mason jar, or whatever you can easily sanitize and use for collection. This technique will allow you to put the airlocked container in a refrigerator and use it up to 10 days later without any issues. You can however go longer with this technique, but much like the liquid yeast you get at your home brew supply store, the cell count diminishes over time. You should be able to do a yeast starter within about a 6 month period of packaging, but your changes diminish over time.

Notes:

-- Always move from lighter colored (less hoppy) beers to darker, so your yeast doesn't impart any color (flavor) to the new beer.

--  Only use yeast from primary fermentation any time after fermentation has dropped your O.G in half.

--  Do not use yeast from secondary fermentation because they are fatigued and contain mutations that you don't want to start in another beer.

--  Only reusing your yeast to many times can also lead to a variant strain of yeast, that might be good, but possibly not as good as the original strain, so try and limit your reuses to 6 or less.

White Labs 001, Wyeast 1056, or Safale US-05?

This is a very common question. It seems there are two types of people; those who don't know that these are 3 brands of the same yeast strain, and the others that know, but have either some kind of brand loyalty for one or prejudice against the others. This post is mainly for those who do not know these are the exact same thing.

Yep it is true. All three yeast brands are derived from Sierra Nevada Pale Ale and are, for all purposes, the same yeast. Even John Palmer, author of How to Brew references them as the same:

“American, Californian, or Chico Ale,

A very "clean" tasting yeast, less esters than other types of ale yeast. Good for just about any type of ale. This strain usually derives from that used for Sierra Nevada Pale Ale. Medium attenuation, medium flocculation. Suggested fermentation temperature is 68°F.”

So is there a benefit to one over the other? Well it depends who you ask. If you ask a home brewer that has been brewing for 20+ years, they will probably tell you to stay away from dry yeast at all costs. If you ask a home brewer that has been brewing for 10+ years they will tell you that White Labs or Wyeast is the only way to go, depending on what they started out on, but if you talk to a new brewer, they will tell you that you should use whatever you would like. But who is right? Well, in my experience, nobody is really wrong.

The truth is if you home brewed 20 years ago, you probably struggled to get a good yeast, and or cultivated it yourself for something that was high quality and had predictable results. Dry yeast didn't have the quality or diversity that it has today.

According to their websites Wyeast started selling yeast almost 10 years before White Labs, but it is my impression, that for whatever reason many home brew supply stores carried White Labs almost exclusively during the late 90s, and I think this led to some brand loyalty from the home brewing community that finally had both a good supply and good variety of quality yeast.

These days most home brew supply stores carry both brands of liquid yeast, plus dry yeast strains, which have come a long way since the early 80s, both in quality and in variety, so how do you know what to pick.

Well, if the same strain is available in all three, let me give you the benefits of all the brands, so you can choose for yourself.

#1. Pitch Rate (how many yeast cells are available in a pack)

- Wyeast 100 billion (at time of packaging)
- White Labs 100 billion (at time of packaging)
- Safale US-05 200 billion (does not degrade over time)

Why you should care. Pitching the correct amount of yeast cells into your beer will help you with a few things. It will give you a good quick and healthy start to your fermentation which helps protect it from infection, helps to provide a thorough fermentation, and limits the amount of fruity esters created in your beer. The recommended pitch rate for a 1.048 starting gravity is 180 billion cells. So, since the cell count of liquid diminishes over time, by the time you get a packet or vial, you are probably around 80-90% of the viability, meaning it is a really good idea to buy two packs, or do a yeast starter. The cell count of dry yeast does not diminish noticeably over time, so you are good to go with one pack.

#2. Price (The amount of money you spend on the same strain of yeast)

- Wyeast $6-8
- White Labs $6-8
- Safale $3-5

Why you should care. Well, money doesn't grow on trees, and dry yeast is roughly half the price for twice the product.

#3. Viability (Is there live and active yeast available to start fermenting beer?)

- Wyeast smack pack (Yeast nutrient in inflatable pack will start live yeast producing CO2, which lets you know there is still viable yeast for pitching, or making a starter)
- White Labs vial (Clear vial lets you see yeast, but exposes yeast to light also. No way to tell if what you see is viable)
- Safale US-05 vacuum sealed package (Light and oxygen barrier pack keeps freeze dried yeast stable and doesn't need to be refrigerated, and will last a long time)

Why you should care. While there are dates printed on each brand, you don't know exactly what kind of conditions the yeast has been exposed to before you got it. Knowing that you have viable yeast can save you a lot of time and heart ache. There are few things worse than pitching your yeast, even in a starter, and having nothing happen.

 

#4. Flavor (This is, after all, why we brew beer in the first place)

I have personally tasted two identical beers brewed at the same time with the same kind of equipment with a similar pitch rate, fermented at the same temperature for the same amount of time, and I have tasted no difference between US-05 and 1056. I have also read countless threads of doubting brewers experiencing the same thing between all three brands. However, don't take my word for it, do a small batch of light beer yourself and see if you can notice a difference. Remember to do a blind taste test, if you are currently prejudice against other brands of yeast.

Why you should care. Because you want to have predictable and consistent results, so you can make your favorite beer again and again.

 

 

So, for my time and money, paying $7 or so for two packs of US-05 for an Imperial IPA vs, doing a two step starter, or paying roughly $35 for 5 packs of liquid, just can't be beat.

Want to save even more money and have the correct pitch rate? Just start saving some of your yeast from the trub of your last batch of beer. Use it over and over again... more on that to come.
