Witches and Wizards Spirits
2026-09-26 17:00 - 21:00
The Witches are back at the Moss Mansion! So get ready to don your witch costumes and come down to the Moss to kick off this spooky season! Enjoy this five-part witchy cocktail experience that will take you through the house and grounds of the Moss Mansion, all while celebrating wonderful witch genres, new and old. Each cocktail station will celebrate a different witchy theme, so costumes off all genres, historic and pop culture are encouraged! Start your season of the witch at the Moss Mansion’s Witches and Wizards Spirits Event!

We will be testing your magic at each cocktail station and will reward your skill with one of our tasty, themed beverages!

5:00 pm – Doors Open…arrive at the time that suits you then check in and pick up your Time Ticket. Time Tickets will be given first come, first served. Once you have your time ticket, you can tour the grounds and enjoy the vendors until your assigned time, then you can enter the mansion.

7:00 pm – Best Costume competitions will be awarded. We love a competition and hope you do too, come dressed up as your favorite witch or wizard for the costume contest and be prepared to strut your stuff. If you are chosen for the contest, you will meet at the pub and display your gorgeous get-up for our panel of judges to vote on!

Your reservation and payment of $55 includes admission to the mansion and grounds, five tastings of our specialty spirits (mocktails available too). There will be food available for purchase, as well as beer at our pub.

Know before you go: You will need to report to the back of the Mansion upon arrival, at the “check-in” station. Your group will be assigned a time to get into the mansion. Time assignments are first come, first served, and groups will enter Moss Mansion (for spirits tastings stations) every 5 minutes. The last admission to the house will be 8:00pm. Spirit stations will be located on three levels of the mansion and outside, so be ready for plenty of stairs with sensible shoes. Please bring a form of ID if you purchased a 21 and over ticket. Reservations are not eligible for a refund but may be transferred by calling 406-256-5100.
