Diageo has applied to patent a method of making naturally sparkling spirits in the UK, the company has confirmed.

The UK drinks giant said today (3 November) that it has filed a patent that describes how to create the sparkle. The patent details mixing a spirit with a yeast and a fermentable carbohydrate to create the sparkle.

Diageo said it is committed to innovation and that it is investing "significant amounts into new product development".

However, a spokesperson played down the prospect of Diageo, famous for spirits brands including Smirnoff vodka and Gordon's gin, unveiling a sparkling spirit in the UK.

She said: "There are no plans to launch any sparkling spirits in the UK at present."

Last week, Diageo confirmed it would begin trials of a red-coloured Guinness in the UK to revive flat sales of the iconic Irish stout. Guinness volumes in the UK were down 1% in the year to 30 June.
