Kerava is a small town of just over 37 000 people. There are a couple of things that are of interest in Kerava. The Sinebrychoff Brewery is located here and was founded in 1819. As of 1999, it is a subsidiary of Carlsberg Breweries. The Koff brand and lager and porter is produced by Sinebrychoff, as well as the Karhu brand. It also owns the license for Coca-Cola, Fanta, Sprite, Bonaqua, Powerade, Schweppes, and Dr. Pepper for Finland. It also produces its own soft drinks - Muumi and Smurffi.  Keravan Vankila is also located here and is an open prison. An open prison is one in which prisoners are trusted to complete sentences with minimal supervision and perimeter security. Prisoners are not locked up in their prison cells. In some cases, prisoners are allowed to take up employment while serving their sentence. Most of the time, these prisoners are considered low risk to the public. The idea here, of course, is to rehabilitate prisoners rather than punish them.
