Bunnahabhain is a Scottish whisky distillery located on the north-east coast of the Isle of Islay. It was founded in 1881 and is one of the oldest distilleries on the island. The distillery is known for producing a range of single malt whiskies that are typically unpeated or lightly peated, which is unusual for Islay whiskies. The water used in production comes from the Margadale spring and the malted barley is sourced from the mainland. Bunnahabhain whisky is aged in a combination of ex-bourbon and ex-sherry casks, which contributes to its unique flavor profile. An interesting fact about Bunnahabhain is that it was one of the few distilleries to remain open during World War II, producing whisky for the war effort.
