Larkfire, the brand that is described as “wild water” for whisky, has launched a new multi-pack as a response to an increase in demand.

The four-pack, priced £4, is available via the brand’s website.

Larkfire was created using natural water, which was chosen specifically to bring out the full flavour of whisky.

It is already stocked by venues including Boisdale Group venues in Mayfair, Belgravia, Canary Wharf and Bishopsgate. Soho Whisky Club also uses Larkfire for its tasting events, and Islington restaurant Frederick’s offers Larkfire alongside its range of world whiskies.

James McIntosh, co-founder of Larkfire, said: “Anyone wanting to enjoy a drink at home shouldn’t have to compromise on quality. We’ve recently seen a surge in demand and want to make sure we’re catering for our loyal customers as well as those new to Larkfire, or those buying it as a gift.

“Die-hard whisky fans know that tap water and bottled water interfere with the delicate flavours of whisky, due to the mineral content and added chlorine or fluoride. But Larkfire is a pure, naturally soft ‘wild’ water from Scotland that creates a natural chemistry, offering the very best for those enjoying a dram at home.”

McIntosh and his team travelled the length and breadth of Scotland to create award-winning Larkfire, and the brand was launched after a study by Swedish chemists Björn Karlsson and Ran Friedman in the Scientific Reports journal helped prove that water boosts the concentration of flavour compounds at the surface of whisky, enhancing the flavour.

 A percentage of Larkfire sales flow back into the Outer Hebrides via a partnership with The Stornoway Trust – a community landlord that looks after 69,000 acres of land on the Isle of Lewis, where the water is sourced.
