K6 Cider Strong Refreshingly Different. It has always been presumed that 'X' means strength however premium liquids of a superior quality have always been marked with a 'K'. So when you want the ultimate in quality look for this K.
I bought a few cans, it tastes good (a WHOLE lot better than Special Brew etc!), and it'll knock you over for just over 3 quid...Bargain!
Erm - Drink responsibly??!!
