It's a mild cheddar, Peter, usually sold sliced in a polystyrene tray at the front of the cheese carousel.
If your local Lidl stocks it, on 3 December if you're quick, you will have 3 varieties of cheddar, as Sobieski said.
West Country Farmhouse Mature 240g
Scottish Mature Coloured 240g
Isle of Man Vintage Reserve 240g
(6.99zl each)
The Farmhouse is likely to be the slightly gritty strong stuff which I don't like. Scottish Mature - no idea what that's like. Ditto Isle of Man Vintage Reserve - but probably very strong. They are all matured over 6 to 15 months, if that's a guide. They appear to be British made, so they should be good. They are fair to good value in price.
Don't know if its been mentioned, but Auchon have 21pln per kg Polish Cheddar
I bring hot news from the chilled cabinet at Auchan Wroc! Kerrygold Mature on a block - special offer seems to be 47zł a kg today and maybe tomorrow and for a limited period. Not much left there, however.

Much to my surprise, a local Lidl had these already yesterday, quite a lot too. They're not supposed to have them until tomorrow, and they had sold out of the last batch when I checked some days ago as above.
They're British-made, so probably are very good.
