Kit Kat is a chocolate-covered wafer biscuit bar confection that was created by Rowntree's of York, England, and is now produced globally by Nestlé (which acquired Rowntree in 1988)with the exception of the United States where it is made under license by The Hershey Company. Each bar consists of fingers composed of three layers of wafer, covered in an outer layer of chocolate. Each finger can be snapped from the bar separately. Bars typically have two or four fingers, although the larger Kit Kat Chunky bars are a single solid block marked into three sections.
Many varieties of Kit Kat have existed, either permanently or as limited editions, such as those sold to commemorate festivals such as St. Valentine's Day. In Japan, Nestlé has introduced over 200 different flavours since 2000, including ginger ale, soy sauce, creme brulee, green tea, banana and wasabi.The flavours are designed to appeal to younger buyers, and are often bought as good-luck gifts as the brand name echoes the Japanese phrase “Kitto Katsu”, roughly translating as “surely win.”
The Kit Kat Orange was the first flavour variant to be introduced in the United Kingdom, in 1996 and 1998 in Ireland. It was followed in 1997 by the Kit Kat Dark and Kit Kat Mint. All three were available as permanent editions of the two-finger multipack in the United Kingdom, along with the Kit Kat Original, the Kit Kat White, and from 2012 the Kit Kat Cookies & Cream.
A wide variety of promotional items exist, ranging from traditional merchandise (such as mugs, pens, oven gloves and tea-towels) to less common items such as coats for small dogs. Recently in Japan, Kit Kats have come packaged with CD singles, and a special limited edition double pack of Kit Kat Crispy Monogatari came bundled with a mini book featuring six short stories, one of which was written by Suzuki Koji, author of the Ring cycle series. In Japan, Kit Kats are also available in jars that are dispensed from vending machines.
