To make Balvenie DoubleWood, The Balvenie Malt Master takes whisky that has spent at least 12 years in traditional whisky casks, American Oak ex-bourbon barrels and hogsheads, and moves it to Spanish oak ex-Oloroso sherry casks for an additional nine months. The whisky is then transferred to large oak vessels called “tuns” for 3-4 months to allow the whiskies from individual casks to “marry”.
