Ok, quick question. My second batch ever. I cooled the wort, poured it through a strainer into my primary, passed it between a couple buckets to aerate it, pitched the yeast, and capped it. After about 5 minutes I remembered I forgot the top off 2 gallons. I sanitized a bucket and dumped in two filtered gallons. Is this going FO mess up the batch??
You'll probably get a "Who knows" response seeing the amount of factors in your situation. It seems you understand that minimal handling is optimal - I'd bet you'll be fine considering the history of brewing beer. Besides - what are your options - you really want to re-sanitize and re-pitch? Give many, many more details just for S&G's.
