I bought a yeast starter set up yesterday, which consisted of a flask and a 1/2 lb. of DME.
Is a stir plate required? If not, what is the best method, and how long, would I need to stir/prepare?
How far in advance can a starter be made? I am planning to brew next weekend, would it be too far ahead of time to make a starter this weekend?
Lastly, can I use dry yeast in the starter? Thats all I have on hand.
