To grow yeast requires:

  • PH level (acidity level ph7-ph1)
  • moisture
  • a temperature between 10 and 50ºC but ideally 30-37ºC
  • a food source such as sugar or flour.

1. Moisture- which is provided by milk or water

2. Warmth- on top of a oven or in a sunny place, which activates the yeast

3. Food- which is provided by sugar or flour

What if the yeast is not working in brewing beer?

There are several reasons this could happen: # The yeast was dead to begin with. # Something is wrong with the conditions for the yeast (temperature, infection, pollution). # The yeast was under pitched and is growing so slowly you can't tell. The solution to numbers 1 and 3 is to re-pitch the yeast as soon as it's apparent that the yeast is not growing. You'll want to use a starter if possible to give the yeast a good head start over any potential infection in the brew. The solution to number 2 is to correct any environmental problems (like temperature) and re-pitch the yeast as needed. If the problem is infection or pollution, however, the batch of beer is basically done for. You may not find this out until the re-pitched yeast also fails to grow. Yeast storage problems are usually the cause of number 1. Be sure to keep liquid yeast packets refrigerated until hours before they are ready to be used.
