Spanish translation?

A Spanish winery website says of their wine

Estos viñedos están plantados en vaso, y en secano, en las montañas del término municipal de Villarroya de la Sierra, en pleno Sistema Ibérico, predominando el suelo arcilloso.

Google translate turns that into

These vineyards are planted in glass, and in dry land, in the mountains of the municipality of Villarroya de la Sierra, in the heart of the Iberian System, predominantly clayey soil.

Vaso is translated as Glass by Google and Spanish - English online dictionaries.

What does the winery mean here by 'vasa'?

There’s a discussion on Guildsomm that suggests it’s term that refers to a training system comparable to head-training (the “goblet” system, hence “glass,” I guess).

[Robin Garr]

"vaso" means glass, a drinking glass, but it also means vase. I wonder if this refers to a style of trellising for the vines.

[Robin Garr]

Yep, that's it. From importer Kobrand's website:

Vine Training & Pruning
Methods of Viticulture
Bush or Gobelet
In Mediterranean or hot wine
regions, vines are bush trained
(called bush in California,
gobelet in southern France,
en vaso in Spain, alberello in
southern Italy and Sicily). The
leaves protect bunches from harsh
sunlight and receive light from
any orientation. These tend to
be older, low-density vineyards.
(1,000-5,000 vines/hectare)

Many thanks (and apologies for not posting thanks earlier).

Yes, translation make sense. I was thinking on the lines of soil type.
