I am over 21 and so are all my friends. If a guest were disrupting the tasting, I would create a natural social pause in the event and pull them aside and ask them to be more respectful if I felt comfortable. Another option for guests not engaging is to delay any of the fun aspects of the event (tasting, music, etc) until I can get everyone's attention. I would be very professional and earnest to keep the vibe light.

I organized an event for a previous employer, which was a social app that launched in LA. We found a loft on Venice Beach, invited over 200 locals and creatives, and got incredible DJs and free food/drinks from amazing brand sponsors. The event resulted in SO many new app downloads and a lot of UGC and beautiful content to fill up all our socials.

When I have hosted parties or brand events in the past, I liked to add personal touches to leave a lasting impression. This has included polaroid cameras with the brand's logo, special-shaped ice for drinks, a DJ spinning vinyl, and so forth.
