Old Winchester is a much older (18 months) version of Lyburn Gold. The cheese is a dryer, harder and more crystalline cheese, becoming more reminiscent of an old gouda with a distinctive nuttiness in flavour.
Because Old Winchester is made with a vegetarian rennet, on a number of occasions the cheese is used as a vegetarian replacement for a hard, Italian cheese, and yet can still be used as a table cheese, it has that bit more versatility. This cheese is for those that like something much stronger.
