Bit disappointed on the lack of response to above question but , hey ho, cracked on today and bottled after filtering. Dropped it onto 5 campden tabs crushed despite no response from suppliers etc as to whether this is good or bad.
Managed to get 27 bottles and another 3/4 that will have to be disposed of in the proper way.
Verdict thus far - very impressed. Has good taste and body even at this early stage. Not sure if it is me or has the campdens altered the taste? Mmmm. Jury out on that one. Gut feeling is that I would bypass this stage next time and take a chance on anything that goes over the supposed 6 month stage.
