Is cider the new ale? Plenty seem to be turning their hand to it's production in these parts, and from what I've sampled locally, making a good job of it too. Pure North apparently nestles in the Holme Valley (now anything that nestles in the Holme Valley gets my vote!) and pride themselves on their preservative free product.
Little more I can't tell you but contacting Rob North through the website would be a step in the right direction. I can't honestly say that I've run into this cider at any festivals yet but it's certainly one to look out for and we wish everyone concerned the best of luck.
