Ok so here is my problem i have 6 gal brew pales one of the lids had a gash in it because my drill bit caught it wrong when i was boring out the whole. any ways i plugged the gash and thought it was sealed, NOPE! so now my primary has been allowing a small amount of air all night. i pitched the yeast into it at 12am and discovered the problem at 11 am this morning. there is a large head of krausen on it. i changed the lid for a new one and its bubbling away nicely now. it looks fine do you think that this will be a contamination issue?
