This morning was the first time I made a starter using a stir plate. I made it this morning at 9 and made a batch of beer while it sat on the stir plate. Now the wort is sitting in the fermentor in my kitchen while the starter continues to make more yeast cells. Should I wait until morning to pitch the starter or should I pitch it now? The OG is 1.064. I'm a little concerned that letting the wort sit overnight, may result in an infection.
