Another defunct badge, to gain Craft Brewer you had to add 25 beers to the untappd database. This was originally designed to be a follow on from Home Brewer (for adding 10 beers) and be followed up by another badge for adding 100 beers, Brew Master.
Unfortunately, instead of rewarding home brewers these badges instead incentivised users to add duplicate entries to the database. To stop this onslaught of beers such as Bud-Light and BuD LiGhT, the two badges were retired.
