"Also the Lewis & Gunn but it's too strong to drink many"

Do you perhaps mean Innis & Gunn?? Great stuff - Matured originally in used whisky barrels, for 37 days (Blonde) of 77 days (Dark). They also have one now matured in used rum barrels but I have yet to try that.

The creation of this beer has led to what must be a fairly novel type of recycling. The brewery uses the empty whisky barrels to mature their beer and the whisky distillery takes the barrels back again once the beer has been bottled to age a new batch of whisky.
