I added yeast to my carboy Saturday afternoon, and the airlock blew off sometime Sunday while I was out. I think the reason is I added too much yeast. When I discovered it, I just assumed the batch was spoiled, and I left the airlock off the carboy. A fellow brewer told me it should be OK as long as I put the airlock back on. It is now Tuesday morning, and I've added the airlock back to the carboy, but my question is: should the batch be OK, or should I dump it?
