Alsace is a highly diversified agricultural region with cereals, livestock farming, market gardening, orchards and hops. It is particularly well known for its wines and vineyards, which stretch all along the Vosges mountains. The VitiVina¹ cooperative explains the life cycle of trellis strings, from installation to the end of their useful life.

The Alsace appellation area stretches over 120 km, covering 15,606 hectares of vineyards, representing 3.5% of France’s AOC² vineyards and 4.5% of Alsace’s agricultural land.

Vine training in Alsace

Trellising allows the vine shoots to be trained upwards to prevent them from falling under their own weight and deteriorating. Once raised, the branches are secured with two polypropylene strings and a clip, usually made of metal, except in the case of manual trellising, where they may be made of photodegradable materials.

In Alsace, trellising is mainly carried out mechanically on gently sloping hillsides and flat plots. The row spacing, 1.6 to 2 metres, allows for the passage of machinery, tractors and trellising machines. This is also explained by the associated gains in working time and labour savings. With mechanical trellising, it is thus possible to cover 3 to 4 hectares per day.

There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrassing hidden in the middle of text. All the Lorem Ipsum generators on the Internet tend to repeat predefined chunks as necessary, making this the first true generator on the Internet. It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which looks reasonable. The generated Lorem Ipsum is therefore always free from repetition, injected humour, or non-characteristic words etc.
