This particular KitKat has a few fewer calories than the average one. Most of the other varieties are 110-120 calories for two fingers. This one is only 100. That vinegar must be good for you!
Yes, you read that right. This is a vinegar flavored KitKat. This sounds a lot stranger to us Western folks perhaps than to Japanese people, who actually have "drinking vinegar" which they consume for health purposes. That is why there is a picture of a refreshing glass of iced vinegar on the front of the box.
If you're interested, there's a survey about the vinegar drinking habits of Japanese folks on the excellent web site, What Japan Thinks. According to the survey, about 56% of Japanese people have at one time or another drunk vinegar. The biggest reason they drink it appears to be to relieve fatigue. Mind you, I don't believe vinegar necessarily helps with anything health-wise, but I'm betting that it probably isn't bad for you and there's probably a chance it's beneficial.
The packaging is interesting because they're using the same inner package wrapper design as the apple KitKat. However, this is a white chocolate-based KitKat rather than a milk one like the plain apple variety.
The bar smells mildly of apple. There is no scent of vinegar that I could detect. The first bite of this tasted like apple cider. I didn't have much of a sense of the vinegar taste until the second bite where it leaped up and tickled the back of my nose. As I finished off the first finger, I had a strong sense of apple vinegar flavor building up.
The surprising thing about this is that it's really not bad. It's not the sort of thing that you'd sample and think the flavors are discordant. The apple vinegar flavor offsets the sweetness of the white chocolate without creating a weird combination. My feelings about this are similar to the ones I had with the Muscat of Alexandria KitKat. That is that I think it's interesting and am happy to have sampled something unique, but I won't be craving it or buying it again. Once is enough.
Note that there is also a lemon vinegar KitKat on the market, but I haven't run across it yet. Both the apple and lemon vinegar KitKats are part of a campaign by Nestlé to get people to use chilled KitKats in summer sweets preparations. There are recipes for concoctions on the cooking web site. The apple vinegar recipes include one for "healthy ice" which is a frozen concoction including (among other ingredients) apples, sugar, condensed milk, cocoa powder and the apple vinegar KitKat. There's also a recipe for "refreshing mousse" which includes the same KitKat, tofu, honey, and yogurt.
