While sipping on your favourite glass of wine – be it white or red, have you ever wondered how your wine was harvested and what needs to be considered before harvesting?
There are five key rules as to what needs to be considered before a complete harvest. Harvesters inspect the colour of the grapes very intricately; red grapes grow from green grapes then gradually turn red. The redder grape, the richer in flavour will be. Harvesters know that this can take some time and need to consider the weather before the optimal ripeness of the grape before harvesting.
Clearly observing the stems of the grapes can indicate whether or not they are ready to be harvested. When the stems turn brown, this is a clear indication that the grapes are ready to be harvested. As sugars increase in each grape, the grape will appear plumper which will allow for easier removal of the grapes in clusters. Harvesters can also test the ripeness by tasting the grapes. If they find that the texture of the seeds are more chewable and the colour brown, then this means the grapes are ripe enough for harvesting.
When tasting the grapes, the riper they are the sweeter flavour they will have. If there is a hint of bitterness in the skin or seeds then the grapes will need to mature more before being harvested. As time has gone on and technology developed, there are many tools that winemakers can make use of to test the quality and other factors before accurate harvesting.
