I dunno, I've been in the UK and had proper scrumpy and other ciders and TBH there isn't a whole lot of difference to them besides being almost flat compared to my cheap juice ciders. Not enough anyway. I'm looking at getting some fresh unfiltered unpasteurised juice from out Thirlmere way to compare it but I'm in no hurry. Also helps that I've turned SWMBO onto sours (besides it being an expensive habit)
I find using Apple/pear juice means it won't ferment all the way dry.
Another option that I've used that worked reasonably is adding some well stewed tea.
