Hmm... first off, if you don't want a ridiculous alc. content, then don't add sugar! The best most purest ciders don't have added sugar. Okay, I've said that now, and will get off my soap box.
Out of curiosity, why did you stop at 1.030? That is really sweet. I'm in wine mode now, and that just seems really sweet and then you added more juice and honey. Glad to see you are going to keg it at that high of an FG. Bottles would not handle that at all.
I have a theory - I don't know if it is true or not, but I *think* JK Scrumpy cider gets juice with about 1.055 SG or so, allows it to ferment dry (1.000 or less) which gives them 7.1%, stabilize it, and then adds back in more apple juice to dilute it down to the bottled 6.0%. Posters have measured it out to be 1.025. It has one of the best apple flavors I've found in a cider, but I think it is because they added back allll that apple juice. Warning: soapbox moment - they are quite proud that they don't add sugar.
