Lark Signature No. 151 Fire Trail is described as the purest expression of Lark's house style in the Signature numbered collection. The expression is matured in rare Port and Sherry casks sourced from Seppeltsfield Wines in the Barossa Valley, and then finished in ex-Bourbon and American oak wine casks. The Port and Sherry cask maturation delivers layers of dark fruit, fig, and spice, while the finishing in lighter American oak brings balance and integration to the Tasmanian single malt. Produced from Tasmanian barley, distilled in traditional copper pot stills, and bottled without chill-filtration. Bottled at 41.5% ABV. The number 151 designates this expression's place in Lark's internal batch numbering system.

Lark Distillery was founded in 1992 by Bill Lark in Hobart, Tasmania, and is widely credited as the pioneering distillery that launched the modern Australian craft whisky movement. Before Lark, Tasmanian whisky distillation had been suppressed since colonial-era licensing laws. Bill Lark successfully lobbied the Tasmanian government to amend those laws in 1992, opening the path for Tasmania's now-thriving whisky industry. The distillery is located on the Hobart waterfront and draws on Tasmanian barley, local peat from the highlands, and pristine mountain water. The Signature numbered series — Fire Trail, Devil's Storm, and Ruby Abyss — forms the distillery's global travel retail collection.
