Yeast

Yeast is what turns our wonderful wort into a bubbly brew. These little critters set to their work in our cooled wort and magically change the sugars we have created in our mash tuns, or poured from our cans of extract, into beer by the means of fermentation. All yeasts are different in small ways, just as people are. That is to say we are all people that breath in oxygen and breath out carbon dioxide, but we all are different in our own special ways. Yeasts are exactly the same. They all consume sugar and convert it into carbon dioxide and alcohol, but they all do so in similar but different ways that produce similar but different flavors. You can use yeast in several forms, and the most common to home brewers are Dried Yeasts and Liquid Yeasts.
We recommend using a liquid yeast every time you brew. It may cost a few pennies more per glass of beer but it is well worth it. Dry yeast will work fine if you can not find a liquid yeast source, but you will taste the difference. One way to reduce the characteristic ╥dried yeast flavor╙ is to control the temperature of the fermentation. Keep the fermenting wort at 68 degrees Fahrenheit by using a temperature controlled refrigerator and external thermostat. For considerably less money you can place your bucket/carboy in a cool bath of ice water with a wet towel or t-shirt draped over it and this will wick the cool water up and around the carboy/bucket keeping it cool.
Dry yeasts are easy to use. They come in a small paper pouch and all you have to do is tear them open and pour the yeast in to your wort. You can also hydrate your yeast by pouring it into cooled boiled water for 10 minutes prior to adding it to your fermenter.
Liquid yeasts used to scare many home brewers because they came in a “smack pack” that required several days to grow the yeast up to a usable amount.  Several companies now offer liquid yeasts in pitchable quantities that is you do not have to grow it up in a starter a few days before use after activating the ╥smack pack╙. Pitchable yeast needs to only be warmed up for several hours before adding it to your cooled wort. Take it out of the refrigerator and set it on the counter when you begin your mash, or half an hour or so before you begin your hour-long boil if using extract. It comes in a vial or tube you simply open and pour into your wort. Easy as 1..2..3..!!!!
The yeast we list here are from the companies that we have had the most experience in dealing and brewing with. Listed in Zymurgy Vol.21 No. 4 Nov/Dec 1998 is an extensive list of liquid yeasts by company. We will not attempt to reproduce that list here, but instead offer a smaller list of yeasts you will find in this book, and in your local homebrew store.

By each yeast are three items you will need in order to understand how that particular strain will work. First is the attenuation rate that is how much of the extract the yeast will turn into alcohol and carbon dioxide. If you have a starting gravity of 1048 (12 Plato) and are using yeast such as White Labs 001 that has an attenuation of 73 to 80, then you can expect your final gravity to be between 2.4 and 3.24 depending on the types of grain in your recipe. The second item listed is the flocculation of the yeast, that is how much yeast “sinks” or “drops outs”  of suspension after fermentation is complete. A high rate of flocculation would result in a clear beer, and a low rate would yield a cloudy beer such as a heffeweizen. Lastly we have listed the optimum fermentation temperature range that the yeast performs at best. That does not mean that if you cannot control the temperature of the fermentation that you should not use liquid yeast. You most certainly should use one; your results will still be far better than if you used dry yeast.

Wyeast 1214 Belgian Ale Yeast 72-75% / Medium / 58-68 : Banana estery flavor. With both clove-like phenolics and alcohol spice. Tartness often develops over time. Ferment warm or with inadequate aeration and you’re likely to get a bubblegum-like note. Intended for abbey beers, and works very well for that. And, depending on the wort composition, lots of banana notes.

Dry Ale Yeasts

As mentioned earlier dry yeast will work well in a pinch but there is no reason to not use a liquid yeast if you can purchase one. Some dry yeast strains preform better than others, but that is also a matter of personal opinion. A favorite is listed first!
Dry yeast should be rehydrated before use. This can be done by sprinkling the dried yeast into approximately 10 times its own weight of sterile water or wort and stirred, then left to sit covered for 15 minutes. Then the creamy mixture is pitched into the fermenter with the awaiting wort at the appropriate temperature. This ╥awakens╙ the yeast and allows it to become acclimated to a new wet environment. Nine out of ten times I brew and use dry yeast I have not hydrated the yeast and it always works out fine. If you hydrate you should notice the wort to start fermentation quicker and by all means this is a good thing!

SO4 Ale Yeast – a good English strain, very flocculent, forms a compact sediment and ferments quickly, neutral English character, can be estery if the temperature is not held below 70F.

S189 Lager Yeast – Originating from a famous German University, reported to be the most popular lager yeast worldwide. Develops the best of its lager characteristics when fermented at 50-57 degrees ferinheight. High sedimentation, good in Pilsners.

Coopers Ale Yeast : The Coopers is quite fruity fermented at 65F. It’s not phenolic at all and all the flavor is a very clean fruitiness.

Glenbrew Special Ale Yeast : Specially designed for use in “all malt” beers. Contains a special enzyme to obtain extremely low terminal gravities.

Edme Ale Yeast : Starts quick. Produces some fruity esters. Attenuative. Good reputation.

Lallemand Nottingham Yeast : This yeast is remarkable for its high degree of flocculation. It settles out very quickly and firmly. Very good reputation. Quick fermentation at 62F. It’s very clean and only very slightly fruity in the keg, but tastes/smells nutty in the bottled version. Nottingham appears to be relatively attenuative (more so than the Coopers). Many new Brewpubs in the 90s used and still use this yeast as a house strain or backup yeast in case there liquid cultures failed them.

Lallemand Windsor Yeast : Produces a beer which is clean and well balanced. This yeast produces an ale which is estery to both palate and nose with a slight fresh yeast flavor. Very good reputation. Not as quick as the Nottingham.

Munton-Fison Ale Yeast :Starts quick. Produces some fruity esters. Attenuative. Fair to good reputation. It is reported that a phenolic taste is no longer a problem due to some strain changes.

Red Star Ale Yeast : This brand had a very bad reputation in the past, and for a while
production was suspended. A different strain (AHY 43391) was selected by the company and is now being sold as Red Star Ale Yeast. The new strain is much improved! Apparent attenuation 76-78%.

Whitbread Ale Yeast : Fast starter. Distribution switched to Crosby and Baker with a change in the yeast. Very good reputation despite past quality problems.
