They also make a bunch of other weird flavors I want to try.. Garlic, Beer Flavored, Cheese Cake, Potato Chip, etc. I'll let you guys explore the rest, just type in "japanese food drops" in the search on this website, but here's a link to the wine ones: http://www.jlist.com/product/KAN054
If anyone tries them let me know how you like.
