I will start by saying this item is not for all organizations. Any organization affiliated with addiction and recovery or even domestic violance as well as some religious affiliations may want to steer clear of this type of item out of respect for the attendees.
With that being said, items including an experience related to alcohol usually has a broad appeal.
Examples of Alcohol Related Live Auction Items
Wall of Wine. This is where all of the board members or auction committee members donate a bottle of wine (some bottles will be higher quality than others) until you have a collection of anywhere from 10-50 bottles of wine, and you sell it as a package. You will want to print any higher end bottles in your program, and ideally would print all of the bottles in the program so people can see what they are bidding. It is unrealistic and much less effective to verbally list all the bottles when introducing the item.
Wine Tasting. A private and exclusive wine tasting in someone's home with a professional Sommelier.
Private Brewery Party. Local microbreweries are popping up all over the place (especially here in Minneapolis), but a tour is not enough because really anyone can go tour a brewery. A private tasting party at the brewery for 10+ people with catering by a local food truck (or two) would be an item worth selling on live auction and would provide an exclusive appeal.
Wheel barrel of Booze. This item is always a hit. It is similar to the Wall of Wine, except it is an actual wheel barrel filled with alcohol. Arrange the alcohol so the higher end items are showing. You could also include glasses and garnishes (olives, cherries, frilly toothpicks, etc) in with the alcohol to fully stock the bar. This is an easy item to fill because auction committee members or board members would all go together to in contributing to this item. The winning bidder gets to take home their new wheel barrel and all of its contents.
