As above, Thomas and Rose Apple and Ginger is amazing. It's my favourite cider by far.As far as Rekorderlig goes, I tend to stick with Apple and Pear. The other flavours are far too sweet.
You could give Zeffer a go as well.
The Rekorderlig Elderflower one is pretty good but all of those type are still too sweet..Gimme a hard dry apple cider anyday though, great in summer.
We used to call the pink Rekorderlig cider "panty stripper" for obvious reasons
