Grape harvest/transport

Mechanical harvest transport does not follow the same rules. The harvested grapes should be brought rapidly to the winery after the juice has been separated from the solid parts to the extent... 

During mechanical harvesting, the grapes are transported in high-capacity containers. Speed and hygiene are even more important in this case, since the grapes are inevitably partially crushed with this method.

Diverse methods, adapted to each winery, are used to transport the harvest from grapevine to winery. In world-renowned vineyards, small-capacity containers are carefully manipulated by hand. In most vineyards, the harvest is transported in shallow bed trailers or trucks. Whatever the container capacity, the grapes should be transported intact without being crushed. Transport containers should also be kept clean. If the transport time is long the grapes... 

Whether manually or mechanically harvested, the grapes should be transported rapidly to the winery in containers that minimize berry crushing. 

GRAPE JUICE. In laboratory tests, unfermented grape juice caused mild attack (2 mpy) of 1100,3003, and 3004 alloys at room temperature. Aluminum alloy equipment has been used for harvesting grapes and grape juice has been transported in aluminum alloy tank cars (see Fruit and Fruit Juices). See also Ref (4) pp. 88, 91. (6) p. 10.
