Single Estate - Terroir
Single Estate indicates that a winery uses fruit (grapes) only from its own estate and does not blend grapes from other regions or estates.
Terroir is a word that has no translation in any other language and denotes the set of above and below-ground characteristics that make a vineyard unique. The soil, subsoil, slope, orientation, climate, microclimate, and, of course, the specific varieties planted there are just some of the factors that make up the terroir, as long as they result in wines that are both high quality and recognizable. In other words, it is a 'monopoly of taste', as stated in the book "The Art and Science of Wine" by Halliday and Johnson.
Today, wine is of great value, both for the economy and for its beneficial properties to human health. Quality control is the process of ensuring that the availability, reliability, maintainability, and manufacturability of a product are standardized. Quality control as a process must take into account the stages of planning, control, and improvement. Quality, in this sense, does not only refer to the durability of a product but also implies compliance with economic profitability, commercial development, and technical safety standards set by the company's management.
Protected Geographical Indication
Geographical Indications (GIs) protect intellectual property rights for specific products whose qualities are specifically linked to the region of production. The PGI emphasizes the link between the specific geographical area and the name of the product, where a particular quality, reputation, or other characteristics can be attributed primarily to its geographical origin. For most products, at least one of the stages of production, processing, or preparation takes place in the area concerned.
In the case of wines, this means that at least 80 % of the grapes used must come exclusively from the geographical area in which the wine is actually produced.
