I moved to the best bit of England in 1980, and I've never known this to be said - cheddar is cheddar, mind you I can't speak for the heathen Yorkies. Here on God's favourite side of the Pennines we have the wonderful crumbly Lancashire, and locally we have Garstang Blue. On the dark side they have Wensleydale, which is fine if you can overccome geographical prejudice.
