A group representing independent brewers is taking on DB Breweries over the right to use a generic beer term.
Micro-brewer Green Man was stopped from using the term "radler" on one of its beers after DB said it had trademarked the name in 2003.
The Society of Beer Advocates says the term radler originates in Germany and came about in the 1920s when cyclists began stopping off for a beer and lemonade.
Secretary Greig McGill says the society believes the term is generic, just like the words stout and draught.
