One of the most crucial processes for growers of gʀᴀᴘᴇvines is gʀᴀᴘᴇ harvesting. The day of harvest is celebrated with fiestas by producers in many nations because it is such a wonderful occasion.
Gʀᴀᴘᴇ harvesting typically begins 30 to 70 days following fruit set, when the color of the berries changes from green to yellow (for wʜɪᴛe kinds) or red-purple (for red varieties). Typically, at this time, the fruits’ sugar content rises while their acid content falls. In general, most kinds develop in the northern hemisphere between August and November, while they do so between March and August in the southern hemisphere.
The ideal time to harvest gʀᴀᴘᴇs, nevertheless, is difficult to determine. The quality of the finished product is greatly influenced by the environment, the soil, the position of the variety, and the growing ᴍᴇᴛʜods. In order to attain the appropriate quality qualities, producers harvest various types or varieties at various maturation stages.
Hand-harvesting of Gʀᴀᴘᴇs
Gʀᴀᴘᴇs are often hand-harvested. Knives and/or electric or manual shears are used during hand harvesting. After cutting full bunches, workers transfer them to the winery (for wine varietals) or to designated warehouses by placing them in collection baskets (table gʀᴀᴘᴇs varieties). Only manual harvesting is permitted for kinds of table gʀᴀᴘᴇs. They would be bruised if they were harvested mechanically. Table gʀᴀᴘᴇs are chilled after being picked before being moved to storage facilities for packaging.
Mechanical Harvest of Gʀᴀᴘᴇs.
Only wine types are used for this technique. In order for the gʀᴀᴘᴇs to fall to a conveyor belt, sophisticated machinery that pass through the rows of the vineyard shake the plants using rubber or other materials. After being collected, extraneous objects are eliminated via a series of webs before the gʀᴀᴘᴇs are brought to a designated dump. After that, they are immediately taken to the winery. These harvesting equipment costs several hundred thousand dollars.
However, many farmers claim that it is extremely challenging to find and retain a large number of sᴋɪʟʟed workers when harvesting is taking place. In order to harvest a large area of vineyard in a single day without having to worry about recruiting and hiring groups of sᴋɪʟʟed people, they therefore explore switching to mechanical harvesting of gʀᴀᴘᴇs. However, for gʀᴀᴘᴇs with very thin skin, mechanical picking is not an option. Many gʀᴀᴘᴇs will undoubtedly shatter in such a situation, which could promote bacterial growth and oxidation.
Fruits like gʀᴀᴘᴇs are delicate. Producers work to get them either to the packing facilities (table gʀᴀᴘᴇs) or the winery as soon as feasible after harvest. Refrigerator tractors are necessary to carry table gʀᴀᴘᴇs across vast distances.
