Fermentation of apple cider is the process by which yeast converts the apple sugars into ethyl alcohol and carbon dioxide. It occurs in two steps. First, yeast converts the sugar to alcohol and then bacteria of lactic acid convert the natural malic acid into carbon dioxide. This hard cider contains 2-3% solids and 2-8% alcohol. Fermentation occurs in presence of these components such as sulfur dioxide, yeast, sugar, and natural acids. Sulfur dioxide is typically added to the freshly pressed juice before fermentation is allowed to begin. It also has the effect of killing most of the bacteria and yeasts present in the freshly squeezed juice.

.  The Pomme d’Alouette Orchard provides apples to a national maker of “hard” apple cider.  The recent growth of consumer demand for cider has encouraged the orchard to plant new apple trees in order to increase substantially its production of apples. The orchard is considering the purchase of a new variety of apple tree.  NeuApfel, developers of the new variety, claim a square acre planted in the new variety will produce the same average yield (in tons) of apples each year as the...
