Fermenting Jar (local brew store or a large jar with stopper and fermentation air-lock) (size will depend on how much you make)
You can make small batches in a 1/2 gallon mason jar with a recap lid, stopper and fermentation lock) this is flexible! use what you have don't go buy a bunch of stuff unless you really think you wanna do more.
Lemon Balm (Melissa officinalis) (fresh plant, you will need large amounts depending on how much you make)
Apple Pie Spice or other sweet spices like cinnamon.
Local or at least Organic Wildflower Honey
Redstar (red package) wine yeast.
