Perry a group of esters that affords them their prominent pear aroma. Another important attribute of perry pears that distinguishes them from cider apples is their relatively higher content ratio of sorbitol to other sugars, such as fructose. Because sorbitol is not readily fermented by yeast, it is not converted to ethanol, and perry therefore tends to have more residual sugar than cider produced from the fermentation of apples. In addition to producing a sweeter beverage, sorbitol also contributes to increased body and a softer mouthfeel in the finished perry. Compared to apples, pear pressing is made more difficult by the
Alcoholic drink jugs suggest that intentionally fermented drinks existed at least as early as the Neolithic period (cir. 10,000 BC). Many animals also consume alcohol when given the opportunity and are affected in much the same way as humans, although humans are the only species known to produce alcoholic drinks intentionally.
