i was busy this week, and i did my mash later in the evening, and then sealed it up in a ale pail for a couple days (its now the weekend, so i can brew). when i opened the lid, it was already fermenting, krausen, bubbles, and all the other signs of fermentation. im not too worried since im going to boil it now, but i am wondering if that wild yeast is eating my fermentables, before my actual yeast strain can, and will that affect my OG/FG. still gonna make beer with it, just kinda curious.
