In a glass jar or pitcher, combine pineapple, brown sugar, water, and cloves and leave to ferment for three days. I couldn't tell, but this drink may contain trace levels of alcohol. However, if you leave it to ferment for too long, you'll get pineapple vinegar. Personally, I like my drinks with a bit of a kick, so I stop there sometimes. Pineapple juice does not produce alcohol on its own. The pineapple itself is very acidic, which prevents any other substance from forming into alcohol. However, during the processing of making pineapple juice, some of the acidity is removed through a process called "caramelization". This means that some sugars in the pineapple are converted into different compounds due to the heat used during processing. As these sugars break down they give off carbon dioxide gas which leaves behind only alcohol and acetic acid. Alcohol has many health benefits when consumed in moderation. It can be useful as an antiseptic agent and may even help prevent certain types of cancers. But if you drink more than this periodically you will become intoxicated, with all the risks that brings. It's important to note that this recipe contains alcohol. If you're pregnant or breast-feeding, should avoid drinking any type of beverage containing alcohol. If you do decide to make this at home, use clove oil instead of cloves.
