Severe pruning reduces the number of nodes from which will emerge the shoots bearing the next season's crop.

False. The most important sugars in grape juice are glucose and fructose.
28. How would a wine be aged in barrels to minimize its exposure to air?
False. Sulfur dioxide levels are monitored throughout winemaking and small amounts are added whenever they are needed.
Women have to weigh the increased risk of breast cancer against the cardioprotective effect of moderate drinking as well as possible effects on the fetus if they are pregnant.
Three things happen: alcohol and water evaporate through the sides of the container - concentrating the wine; some oxygen dissolves in the wine - allowing oxygen-dependent maturation reactions to occur slowly; and substances - color - odor - and flav
The barrels would be sealed tight - rotated 30 degrees to wet the bung and tighten the seal - and not opened until the aging was complete.
