Laphroaig embraced the use of different types of casks with the Quarter Cask release of 2004. A NAS spirit, the Quarter Cask starts aging in the typical ex-bourbon barrels, then transferred to smaller “19th century-style quarter casks” as described on the the carton. The theory is that, with more surface-to-volume area of the smaller cask, the flavors from the oak are more quickly absorbed into the spirit. While that may be so, there is a noticeable mellowness seen only in older whiskies, so I would hold that aging has more to it than surface area. Who knows, maybe you could get a good whisky by dumping the spirit into a vat full of toothpicks for a couple months, but Scotland has that 3-year aging rule for whisky.
