The Champion Winter Beer of Britain is an award presented by the Campaign for Real Ale (CAMRA) at its annual Great British Beer Festival Winter.
The award is similar to the Champion Beer of Britain which is presented at the Great British Beer Festival.
Category winners are then re-judged to determine the supreme champion — the Champion Winter Beer of Britain.
Beers are split into categories depending on their style or strength with Speciality ale categories joining in 2023 from the main Champion Beer of Britain competition.
There were two National Winter Ales Festivals in 1997.
