Let me begin by stating that I will be purchasing a hydrometer with my next visit to the brew store. I thought I wouldn't need one to get started. "Our ancestors made great beer without any fancy-shmancy contraptions!" Now I see the err of my ways.
Two weeks ago Saturday AM, I brewed a batch of LME pale. On Sunday evening I left on a trip. At this time there was not yet any activity in the airlock. Upon return (1 week +) there was no activity, not that there would be. Obviously, without the right equipment I have no way of knowing what, if anything, happened in the interim.
My plan is to RDWHAHB, but here is my question: What will be the result if there was little or no fermentation going on while I was away? Bad taste? Low alcohol? Toxic sludge?
