Thinning out

Reduction of the grape crop as a quality-improving measure in the vineyard, also known as thinning out, berry thinning, green pruning and green harvest, as well as French vendange vert (green harvest) or éclaircissage. The reason for this is that high yield and high grape quality are mutually exclusive. By removing grapes, an increased accumulation of various substances in the remaining grapes of the vine is achieved. The effects are an increase in extract substances, higher must weight, optimisation of the leaf-fruit ratio, higher colour intensity in red wines and better resistance to drought. Apart from the general increase in quality, a positive long-term effect can be achieved especially with young plants, because they can develop much better.

Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.
