Bruichladdich Octomore (~130 ppm) and Ardberg Supernova (~100 ppm I think) are way up there beyond the Ardberg 10. Off the top of my head I'd guess the Ardberg 10 is something like 20-40 ppm. The "ppm", in the Scotch context, is for the amount of peat phenols, which is essentially a peatiness metric, and it is recently a competition metric, for some reason, between at least a few distillers ( http://blog.thewhiskyexchange.com/2009/03/bruichladdich-octomore-ardbeg-supernova-tasting/ http://blog.thewhiskyexchange.com/2009/03/bruichladdich-octo... as an example article but you can just google scotch ppm and get a ton of articles ). I haven't had the Octomore but the Supernova is not that great in my opinion. It was interesting to taste a Scotch intentionally that peaty, but I'd consider it more of a novelty than a great taste improvement. That said taste is an amazing thing, so it might be precisely your cup of tea. In terms of enjoyable smokiness I'm with you on the Ardberg, but in terms of the crazy +peatiness competition in Scotches, it isn't the winner.
