Joint managing director Paul Burton said: “We don’t want to comment much because we don’t want to prejudice our case if it becomes a full-blown court case.
“But we are defending it robustly.
“It is a drink containing vodka, just as there are a lot of other drinks containing vodka, and it’s clearly labelled on the front as 22% abv and described as a classic schnapps drink”.
Diageo confirmed that it has “commenced proceedings against the makers of Vodkat for passing off and breach of regulations on the definition, description, presentation, labelling and the protection of geographical indications of spirit drinks”.
A statement for the company added: “It is inappropriate to comment further on pending legal proceedings.”
