Yesterday, I brewed a Belgian Chocolate stout recipe from Briess. The yeast I am using is White Labs WLP575 Belgian style yeast. The yeast had just expired so I made a yeast starter a few days ago. I pitched the yeast into the wort at the temperature of 66F. This morning, the temperature was 74F; and right now, the temperature is 77F. Do I need to be concerned that the fermentation temperature is getting too high?
