Site Help | Adding Beers

To add a Beer, go to the "Beers" tab and select "Add Beer." It will prompt you for a country, then a brewery and once you select the brewery you'll be presented with a list of existing beers. If yours is not listed simply enter its name and complete the review, or click on an existing beer to review it. You can also add a beer from a brewers page.

Note: a user must have 20 beer reviews or more in order to add a new beer.
