One thing that could help (assuming your inclination is to take them as a sponsor) is to separate two elements, accepting money from a brewery and how the team advertises the sponsor, as is typical in FRC.

Yes, there are some folks that would be strongly opposed to any interaction due to personal beliefs surrounding alcohol. However, breweries and other food production facilities have increasingly large amount of process control, automation, etc... and they employ many STEM professionals.

However, as Billfred alluded to, I would not want to be seen as advertising alcohol at a high school robotics competition, whether directly or indirectly. You might be able to use this to your advantage to strike a middle ground. "We would love to have XYZ Brewery as a sponsor, but are unable to advertise alcohol or use the word brewery on our promotional material, would it be ok if we advertise an individual non-alcohol product as thanks for your sponsorship?"

If you strike that deal up front, it might help settle any concerns from folks that hear "brewery sponsorship" and jump to wild imagery of a pallet of beer showing up for Saturday lunches at build day and your team designing a still for SteamWorks. (which in a parallel universe, sounds pretty cool)
