Unpeated malted barley is used to create the Tobermory Single Malt, which is then aged for at least 10 years in oak barrels. In tiny amounts, a strongly peated whiskey called Ledaig—the name of the original distillery—is also produced. Several mixes, like as Scottish Leader and Black Bottle, include the malts. A private lake next to the Mishnish lochs provides water for the distillery. Prior proprietors had used the Tobermory moniker for both a single malt and a blended whiskey, confusing the branding. The distillery's capacity was increased in 1990, enabling it to produce a million liters of spirit annually. It employs four Oregon pine washbacks, a classic copper-domed cast iron mash tun, and four spirit stills. The whisky is aged in barrels that previously held sherry and bourbon whiskey. At the Deanston distillery, maturation takes place.
