Short Version: In addition to our valid IDs being rejected at Mystic, the staff was rude and condescending in doing so. Long Version: We had friends in town this weekend and wanted to take them on a mini brewery tour of Boston. Despite an awesome time at Trillium, Idle Hands, and Night Shift, our visit to Mystic left something to be desired. As young professionals in our early to mid twenties, we obviously expected to be IDed at Mystic. After presenting the bartender with 3 valid New York licenses, he told us that he couldn't serve us without seeing the hologram on the IDs. I know nothing about IDs so it's possible that in the dimly lit tasting room he just couldn't see the hologram or it's possible that NY IDs don't have a hologram or it's possible that since my ID is a few years old that it was before holograms were added, whatever. He then asked if we had any backup ID and we furnished a number of additional items ranging from debit cards to old college IDs to a corporate AmEx. Apparently this still wasn't enough so he called over another bartender. That bartender similarly didn't accept our IDs, so we gave up and left. It was disappointing enough-and a bit embarrassing-to have our valid licenses rejected; however, throughout the entire ideal the two bartenders were speaking to us condescendingly and smirking at us as if they "knew" that we had fake IDs and had "caught" us. I'm not sure what underage kids are trying to get drunk off of 2 oz. samples of saisons, but I understand with the recent sting at Wachusett that breweries need to be careful. Instead of being apologetic though we were treated like a bunch of kids presenting a blatantly phony ID. As we were exiting the brewery, we could hear the staff mocking us with other visitors to the tasting room. Although I was excited to try Mystic since I'm a recent saison convert and like supporting local breweries, I won't be returning. With so many local breweries like Jack's Abby, Trillium and Night Shift where the staff is friendly and and loves discussing their beer with you, I think I'll be content going elsewhere.
