From time to time I use C-Brite to sanitize. There are always a few teaspoons left in the bottom of the carboy after dumping the solution despite trying to get it all out. Today there were only a few minutes left to cool my wort completely. In that down time, I pitched the yeast into the fermentor. As I looked at it, I wondered if that little bit of solution would have an effect on the yeast being in direct contact. The yeast was out of the package no starter solution to dilute the yeast.
For the most part I pitch into the wort. Was trying to maximize time I guess. Any harm done?
