Advent Kit
Over 2 years, I have created 36 advent calendars with the following supplies. They feel premium and have held up well. This kit is 2oz bottles which splits a 750ml bottle 12 ways.
2oz bottles, 72 pack
What's to love: The box comes with 72 two-once bottles. This will serve to fill 3 calendars of 24 bottles. The twist tops are great and allow for easy reuse. My recommendation is to buy them before you need them because product availability and shipping can be delayed the later you go in October and November.
Where to find: 72 Pack 2oz Tasting Bottles
Advent Sticker Pack
What's to love: These stickers are fun, the perfect size, and provide a unique experience each day. The first year I went with a multipack that brought variation across calendars but I realized it's best if each pack has the same look and feel because it simplifies the filling process. Lastly, the brown background color of these is a nice complement against the caramel color of whiskey.
Boxes for 24 bottles
What's to love: The bottles above come in a 72-pack and can't be repurposed for distribution of your calendar. These boxes are the closest fix I could find and nicely fit 24 bottles on a single layer allowing for a better presentation. I cut the styrofoam inserts from the above box and placed them into these boxes.
