The new bottle uses biodegradable paint, cork with a wooden top and a paper seal to ensure it is 100 per cent recyclable.
Made by the Isle of Wight Distillery, the design aims to resemble a mermaid's tail and the colours of the sea. It has also been weighted forward to make it easy for bartenders to handle and there's a flange for easy pouring.
"There's now real style to our substance - this stunning bottle is the perfect showcase for what is a top-quality gin," said co-owner and head distiller, Xavier Baker.
"The investment has ensured that we can really push on - in a way that properly reflects our personally-held environmental concerns."
Mermaid Gin is the company's flagship spirit and is made with 10 ethically-sourced botanicals, including organic lemon zest, grains of paradise and rock samphire.
The company also produces a Navy Strength gin, a rum and a vodka so far with, "ambitious plans for 2019-20, with a range of extensions across all categories."
