White Labs Yeast can be stored in a dry, dark location at cellar temperatures of approximately 50-55°F (10-13°C). It is important to store it away from any direct contact with light, especially sunlight or fluorescent lighting.
Refrigerators should be avoided because they provide too much humidity. The only exceptions are the Oyster Bay and San Francisco Bay strains, which can be stored in the refrigerator at all times. The yeast can be stored for up to 3 months if refrigerated and for 1-2 months if stored at cellar temperature.
It is best to store the yeast in an air-tight container or resealable foil pouch and always store at the proper temperature. It is very important to keep the yeast from being exposed to any oxidation or contamination, as this can affect the yeast’s viability.

Does brewing yeast expire?
No, brewing yeast does not expire. However, it is recommended to use the yeast within 6 months of purchase for the best results. After 6 months, the yeast will begin to lose its viability and may not perform as well in your beer.
How much yeast do I put in a white lab?
Assuming you are making a standard 5 gallon batch of white wine:
-For a dry wine use 35-45 grams of dry yeast or 3-4 grams of fresh yeast
-For a sweet wine use 45-60 grams of dry yeast or 5-6 grams of fresh yeast
-For a sparkling wine use 60-120 grams of dry yeast
How long do yeast cultures last?
Yeast cultures generally last for several weeks to several months if they are well cared for. However, if a yeast culture is not used for a while, it will slowly die off and will eventually need to be replaced.
How do you preserve yeast culture?
The best way to preserve yeast culture is to store it in a cool, dark place. Yeast culture can also be stored in the refrigerator, but it will not last as long.
How can you tell if yeast is still good?
You can tell if yeast is still good in a few ways. One way is to look at the expiration date on the yeast packet or jar. Another way is to check the color of the yeast. Active dry yeast should be a light brown color while fresh yeast should be creamy white.
You can also check to see if the yeast is still active by proofing it. To do this, mix the yeast with water and a little sugar. Then, wait 10 minutes to see if the mixture foams. If it does, your yeast is still good.
How do I know when my yeast starter is done?
There are a few ways to tell when your yeast starter is done:
1. You will see a layer of sediment at the bottom of the container.
2. The starter will have a slightly sour smell.
3. The starter will be less foamy than it was when you first started it.
4. The starter will have a slightly yellowish tint.
5. You will see small bubbles forming on the surface of the starter.
How long should yeast starter sit on stir plate?
Active dry yeast and fresh yeast should be proofed or rehydrated first by sprinkling or placing in a small amount of warm water (105-115°F) for about 5 minutes. This allows the yeast to rehydrate and become active before it is added to the starter.
If you add the yeast directly to the starter wort, it may not become as active and may not produce as much alcohol.
Yeast starters should be allowed to sit on a stir plate for 12-24 hours before being used. This allows the yeast to become fully active and produce enough alcohol to ferment the wort. If you use a yeast starter that has not been on a stir plate for long enough, it may not be as effective in fermenting the wort.
Why is homebrew 60 minutes boiled?
This is done to sanitize the equipment and ingredients. boiling for 60 minutes will kill any bacteria or wild yeast that may be present.
Is a 90 minute boil necessary?
A 90 minute boil is not always necessary, but it helps to ensure that all the wort is properly boiled and that any unwanted bacteria are killed. Boiling also helps to extract hops bitterness and to evaporate some of the water from the wort.
Should I stir the wort during the boil?
Yes, you should stir the wort during the boil to help it evenly distribute the heat. This will help to prevent any hot spots from forming and scorching the wort.
What happens if you boil wort too long?
If you boil wort for too long, the proteins will start to coagulate and fall out of solution. This will cause the beer to be hazy and can also lead to off-flavors.
Why does beer need to boil?
The brewing process of beer consists of many steps, but boiling is a key step in the process because it helps to extract flavors from the hops and also kills any harmful bacteria that may be present.
Boiling also helps to break down the wort, which is the sweet liquid that is extracted from the grain during the mashing process.
Does a longer boil increase gravity?
A longer boil will not increase the gravity of your beer. The gravity of your beer is dependent on the amount of fermentable sugars in your wort before boiling.
How long do you have to boil beer to remove alcohol?
It is not possible to remove all alcohol from beer through boiling. Some alcohol will remain in the beer after boiling.
Does White Labs yeast need a starter?
White Labs yeast is a high-quality yeast that does not need a starter. However, if you are using White Labs yeast for the first time, it is recommended to make a starter. This will ensure that the yeast is healthy and will give you the best possible results.
Is a stir plate necessary for yeast starter?
No, a stir plate is not necessary for yeast starter, but it does help to improve the health of the yeast and to increase the volume of the starter. A stir plate also helps to keep the yeast in suspension, which is important for oxygenation and for preventing the yeast from settling out and becoming dormant.
How much DME should a starter have?
In order to make a good estimate for how much DME you will need for your starter, consider how much wort you will want to produce in total. For a 5 gallon batch, you will need a bit more than 3 quarts of wort.
Using the ratio of 1 cup of DME to 1 gallon of wort, you can estimate that you will need approximately 3 and 1/3 cups of DME.
