International Women’s Collaboration Brew Day (IWCBD) is a worldwide annual event that takes place on and around 8th March every year to mark International Women’s Day.
Brewery teams and home brewers are encouraged to come together with their communities and local groups to celebrate women in the beer industry, and to create and release collaboration beers inspired by a central theme, raising funds for women’s causes.
The IWCBD campaign theme for 2027 is UNITE SUSTAIN – Sustaining beer means looking after both the planet and the people. From greener brewing to stronger communities and a more inclusive industry, for IWCBD 2027 we’re coming together to reflect on our roles in building something that lasts.
**We will open an initial Commitment to Brew sign up form on 30 October 2026.**
Through the IWCBD 2026 campaign £33,889 was raised across 88 brew day projects worldwide, with 1,153 participants!
