Co-op Sea Salt and Chardonnay Wine Vinegar Only ever found them in Portishead Co-op though. I am on a lifelong quest to find the greatest S & V flavour crisp, I've tried hundreds of them and the above effort from the Co-op is in my opinion by far and away the best. An honourable mention goes to the Shallot Vinegar flavoured crisps I found in France last week, a reyt posh S & V that one!
