When should I take yeast out of fridge?

Yeast taken out of a fridge needs some time to return from being dormant (or being of very low metabolic activity) and 24 hours at “room temperature”(20C) should be enough. If the yeast culture is active and has nutrients/sugars then it will ferment.

Water at 81° to 100°F is the optimum temperature range for the fermentation process. Water at 95°F is the fermentation temperature that yields the best result. Water at 140°F or higher is the kill zone for yeast. At temps like this or higher, you will have no viable live yeast left.

What happens if you add too much yeast?

Too much yeast could cause the dough to go flat by releasing gas before the flour is ready to expand. If you let the dough rise too long, it will start having a yeast or beer smell and taste and ultimately deflate or rise poorly in the oven and have a light crust.
