We’re still on Island expressions, and time to address a No Age Statement offering from Laphroaig: the Quarter Cask. A quarter cask is a cask one quarter the capacity of a hogshead. More specifically, a sherry butt (500 liters). The Laphroaig folks use a 125 liter cask, which gives, compared the their normal casks, a 30% greater cask (interior) surface area for a given volume of whisky. A higher whisky-to-oak ratio.
That ratio, it is presumed, allows the goodness of the charred oak to infuse more quickly with the spirit, rendering a quicker maturation. They also point out that the surface-to-spirit ratio also increases the ‘Angel’s share’ of alcohol which evaporates out of the oak. True enough, and that evaporation is displaced with good sea air, of which Laphroaig distillery has plenty. In the end, this is a gambit to allow the whisky master to create a whisky with the balance and sophistication of a fully (e.g., 10 or 12-year) matured whisky with spirit what hasn’t aged as long. Alchemy, I say! Can you get gold from lead (well, without a nuclear reactor)?
