Blueberry Wine
What is wine? Basically, wine is fermented fruit juice. Typically grapes are used to make wine because grapes have the right balance of sugars, acids and enzymes to make good wine [Footnote 2]. This is important because the workhorse behind wine is yeast. Yeast is a tiny organism that under the right conditions will consume simple sugars. As it consumes these sugars, one of the byproducts is alcohol.
