I buy my whisky from German websites, and they charge app. 25 Euros for a Laph 10, and around 37 for a 10 CS. I always think the latter is the best buy of the two (still, the 10 is a high quality malt, how can it sell for such a relatively cheap price?). Recently I was graciously sent a sample of a Signatory Laphroaig 11 Yrs finished in port wood at 46 % NC. It's a *fantastic* dram even if it, as far as I can tell, didn't spend much time in the port pipe.
Ian Henderson said, tongue-in-cheek I suppose, that people who state the 15 year old as their favourite do so because they don't like the pungent and peaty 10. I wonder, did he not refer to the CS?
However, just the other day I opened a bottle of the 40 % and was positively surprised. It was not at all as flat and dull as the bottle I bought a year ago. Much better, but still miles away from the CS.
