Not a lot.
What we say:
Hamish saw this in the Co-Op in St Mawes and we thought it might be nice to try it. We have all been a bit annoyed by the adverts that emphasise that it is "cidre" not "cider" but really we can confirm it tastes just like cider. Hamish describes the taste as follows: "A deep flavour. With a rich aftertaste. Quite easy to swig. A warm feeling at the back of your throat. And when you drink it, it doesn't really feel like you have. A kind of melodic undertone."
Amazing.
