Mine bottomed out at 1012 I think, I think the instructions say 1014 or below but the instructions are sparse and not much cop on St Peters kits anyway.
I must admit it does seem low especially for this kit which actually has a nice body with it..
I am sure it will taste okay just seem how it goes, I would try one in a few weeks. I tried one of mine after 2 and it was drinkable then. Did you try a sample out of FV? I normally take a swig from the dregs of my bottling bucket.
Funny enough I had an original Ruby red last weekend it was given to me by a work mate who had a load and needed to get rid of some as they were close to their sell by date.. I don't know if age had affected it but it was very dark and I actually much preferred my own, it was still okay and nice if a little bitter.
The kit makes a very nice pint. Malty Fruity and I get that spicy hop finish.. I am sure you will enjoy yours.. by the sounds of things yours will be about 5.3%
