Sip Some Wine with BV Thermal

Have you ever wondered what the difference is between white wines and red wines? To make white wines, grapes are fermented without their skins, whereas red wines are made from grapes fermented with their skins.  Yeast is added to the juice of crushed grapes or other fruits.  This conversion of sugar into alcohol is called fermentation.  In the mid-1800s, Louis Pasteur (the scientist who created pasteurization) studied fermentation.  A few decades later, Eduard Buechner’s experiments with fermentation earned him a Nobel Prize and helped usher in the era of biochemistry.  But even before these 19th century scientists researched fermentation, wine and other alcohol was produced since ancient times.  There is evidence of an ancient Chinese recipe for fermented rice and honey.  By the end of the first century B.C.E., wine had spread commercially across the Roman empire.  Up until the mid-20th century, fermentation was done using naturally-occurring yeasts.  This led to inconsistency and sometimes spoilage.  Commercial wineries now use brewer’s yeast (a pure starter strain of a Mediterranean yeast), which results in quality wine production.  Temperature influences how quickly and efficiently yeast changes sugar into alcohol, therefore, chillers are necessary for accurate temperature control.  To help with your wine-making process, BV Thermal has portable chillers that are easy-to-use.  For more information on our portable chillers, go to
