So, this was my first batch. 5 gallon full boil. Temps good & controlled with a stc-1000. Aerated with o2 wand. I pitched at 5:30 pm yesterday. Anyways, this is what I did wrong. When I went to dump the yeast into my glass carboy, I sprinkled the yeast on the funnel then immediately dumped the wort into the carboy....but the funnel had been sanitized with star san. Did I ruin the yeast?
