The distillery was founded in 1823 in a former brewery, which had been founded in 1797 by John Sinclair. This unpeated malt is part of the Islands subregion of the Highlands. Its yeast and water are drawn from dark aromatic Isle of Mull peat lochans. The flavour is described as a light smoky nose, a medium dry profile with a smooth and fruity tang. The distillery also produces a smaller amount of peated whisky, Ledaig (pronounced Letch-ick), which is also the original name of the distillery.
Tobermory was originally a vatted malt, but was produced as a single malt after reopening in 1990.
