8. Here's where things get a little more technical. Photosynthesis from the
sun creates a chemical called 'sucrose', which the hormones in the
vines then convert into sugars. These sugars are then sent to the
berries (which will later become grapes) and hydrolyzed into glucose
and fructose. The more fructose and glucose in the berries, the more
flavor and aroma producing compounds are created, making for a
tastier wine. In simple terms, heavy sucrose (sugar) levels alongside
minimal water concentration from a harsh environment allow the
grapes to become full of life and body, thus making some mighty tasty
vino juice.
