As a coach at a private school, I'm quite certain that I would have my administration's support if I could secure a sponsorship from a beer company.
Public schools, though, would likely have a problem with a Bud (or other) logo on your team's shirt or robot.
I'm under the assumption that the school entity, not FIRST, would be the deciding factor.
NASCAR recently started allowing hard-liquor sponsorships on race cars. Previous to this season, these were not allowed because (obviously) the combination of drinking and driving doesn't seem to work. Sponsorships for teams are increasingly hard to come by, even at that level. This past off-season, there were enough teams that had potential sponsorships from companies like Jack Daniels and Smirnoff that NASCAR had to re-visit the issue and, in the end, the sponsorships were approved.
I don't think that FIRST should disallow these adult-oriented sponsorships. These decisions should be left up to the school system.
