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)
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.
US-05 is my choice for convenience, higher cell count, and cost repectively. Just buy a few packets and leave them in the fridge for impromptu brewing session, insurance if some other beer doesnt start fermenting due todead yeast and you can then pitch a packet, or even to try an squeeze a few more points out of a beer that stopped fermenting and left you with too high of an FG. Don't overthink it, too much evidence on the side of US-05.
