Depends whether you want to physically stock it or not and what quantity you want to sell. Reckon the easiest way's to set yourself up as a broker and just buy and sell while leaving the alcohol at the distilleries. Try http://www.hmce.gov.uk/
and they might help
I agree with Pinotage if Robinson wants to sell in cases but I read "bulk" to mean large quantities i.e. drums, IBC's, tankers etc. and that comes under a different scheme. If we knew what bulk means then we could help a bit more
