Medieval grape harvesting.

The *harvesting of wine grapes* (Vintage) is one of the most crucial steps
in the process of winemaking. The time of harvest is determined primarily
by the ripeness of the grape as measured by sugar, acid and tannin levels
with winemakers basing their decision to pick based on the style of wine
they wish to produce. The weather can also shape the timetable of
harvesting with the threat of heat, rain, hail, and frost which can damage
the grapes and bring about various vine diseases. In addition to
determining the time of the harvest, winemakers and vineyard owners must
also determine whether to utilize hand pickers or mechanical harvesters.
The harvest season typically falls between August & October in the Northern
Hemisphere and February & April in the Southern Hemisphere. With various
climate conditions, grape varieties, and wine styles the harvesting of
grapes could happen in every month of the calendar year somewhere in the
world. In the New World it is often referred to as the /crush/.^[1]

*Harvest season[edit]*

The majority of the world's wine producing regions lie between the
temperate latitudes of 30° and 50° in both hemispheres with regions
lying closer to the equator typically harvesting earlier due to their
warmer climates. In the Northern Hemisphere, vineyards in Cyprus begin
harvesting as early as July. In California some sparkling wine grapes are
harvested in late July to early August at a slightly unripe point to help
maintain acidity in the wine. The majority of Northern Hemisphere
harvesting occurs in late August to early
