there is a Glenmorangie finished in Fino Sherry Casks, that should be dryer than Oloroso or the like. "Dry" is, I haste to mention of course a subjective category. In the Distillers Edition of the Classic Malts of Scotland the Glenkinchie is finished in Amontilado casks and the Oban in Fino sherry casks, too.
If you look for a dry accent in a malt, especially in the finish try the Northern Highland malts like Royal Brackla, Teaninich or from closed distilleries a Glen Mhor or Glen Albyn, a Millburn. Tomatin, for me the most southerly of the Northern Highland stills can be pleasantly dry. Old Pulteney of course, Clynelish, Brora.
