How Picking Conditions Affect Grapes & Wine





Many people don’t know that growing and picking conditions affect the qualities of the grapes and wine. For example, grapes become ripe much quicker in warmer climates (i.e. closer to the equator). Or that many vineyards test chemical components of the grape when determining if it’s ready. Every single factor that you can think of has some effect on the grape.


Certain wines like sparkling wines require grapes that are picked slightly before they reach ripeness, so as to maintain some acidity. There are some qualities that can only be detected by humans however. This is why some vineyards and wineries still use humans to pick grapes as opposed to machines. A machine cannot detect broken skin on a grape, which could be a big risk.


There are actually a certain variety of grapes that can only be handpicked, and they are required for dessert wines among many other types. These ‘botrytis bunches’ are essentially grapes with fungus growing on them. Similar to the fuzzy grey growth you will see on strawberries, this fungus comes in many varieties. This is where growing conditions are important, because dryer climates grow a form of this known as ‘noble rot’. In this case, more liquid leaves the grape and results in a concentrated grape.


This is why it is important for some vineyards to only have human pickers. Without a human’s intuition diseased grapes may get into wine and make people sick. Many people also believe that picking grapes during the nighttime and daytime have different effects on sugar levels. It has also been said that grapes that are picked during a rain have a ‘watery’ taste. All in all, the growing and picking conditions of grapes have a large effect on the quality of grapes and wine you will receive.
