Is it legal for brewers in CA to sell online?

Although we encourage you to follow the advice of the legal counsel of your choice, Bevv has diligently researched this matter and has been in direct contact with the California ABC to ensure compliance.  In the words of the California ABC itself, "The Department has determined as a matter of policy that it is permissible for those licensees to solicit and accept purchase orders for their alcoholic beverage products from consumers by direct mail, telephone, or on-line computer."
