National Homebrew Day is observed annually on the first Saturday of May, with the next occurrence on May 2, 2026. This day was established by the American Homebrewers Association in 1988 to promote homebrewing and foster a sense of community among homebrewers across the United States. The celebration includes the central event known as the Big Brew, where homebrewers gather in public spaces to brew beer, cider, or mead together. Participants often follow an official recipe provided by the AHA, but they are free to choose any recipe they prefer. The day encourages individuals to engage in various activities such as attending local Big Brew events, organizing their own brewing sessions, or sharing their experiences on social media using hashtags like #NationalHomebrewDay and #BigBrew. The history of homebrewing dates back thousands of years, and it faced legal challenges in the U.S. until it was legalized in 1978.
