Dunnet Bay, the most northerly distillery in mainland Britain, is to launch its first vodka this month.
The wheat-based vodka will be hand-distilled and feature local botanicals.
It takes its name from Holy Grass, which is indigenous to the banks of the nearby Thurso River but sourced from elsewhere by the team due to its protected status locally.
The vodka will also be infused with Highland apple vapour and apple juice.
Holy Grass Vodka is the Caithness-based distillery's third release after Rose Rock Gin and Rock Rose Gin 'Navy Strength' were launched earlier this year.
Co-owner Martin Murray said: "Our Holy Grass Vodka is a tribute to Robert Dick, a legendary botanist from Tullibody, who lived in Thurso in the 1800s.
"As with Rock Rose Gin, we wanted to create a spirit that captures and celebrates the heritage of Caithness and its local botanicals.
"We are excited to be entering the craft vodka sector with such a unique offering."
Rock Rose Gin has won a number of awards, including a bronze medal at the 2015 San Francisco World Spirits Competition. nationally in 2015.
Rock Rose gin was recently chosen by the UKTI to take part in a gin-trade initiative across the US.
The distillery also won Best New Business at the Highlands & Islands Food & Drink Awards in October 2015.
It was opened by husband and wife team, Martin and Claire Murray in 2014.
