Ian, I had the opportunity to try the Committee Reserve in January at Las Vegas PLOWEDfest (aka Ardbeggeddon). One of the PLOWEDsters had recently visited Scotland and came home loaded down with 50 bottles of malt!!! (a 70cl bottle goes about 2 kg - so he had 100 kg of malt in his baggage!!!) One of his offerings was the ACR. Not even close to the best Ardbeg that I've ever tried, but very good for a young 'un. Primarily ex-bourbon casked whisky, most of it 8-10 years, with a bit of older malt added in to give it some depth.
Worth the 45 quid IMO.
Hope this helps,
