Wine tasting aims to formulate a reliable and truthful judgment about its intrinsic and extrinsic qualities. Experts and professionals in the wine sector need to have a standard measure in order to be able to arrive at an unambiguous evaluation. The ISO glass model for wine tasting responds perfectly to this purpose. It was conceived around the 1950s following the development of studies aimed at achieving a perfect taste-olfactory perception. We offer the best quality ISO glasses. Our wine glasses are perfect for events, fairs and events dedicated to wine and its world.
ISO glass: in search of the perfect tasting
Wine tasting can be assimilated to the discovery of the many secrets that the nectar of the gods hides through the color, the scents and the tactile sensations that are released upon tasting. Indeed, it can be considered a wonderful world that thrills in anticipation of being known to express itself freely. Wine is a bit of all of this. To achieve this goal, however, the correct instrumentation is required, of which the main protagonist is the ISO tasting glass. The wine tasting glass has very specific characteristics to be able to grasp the more than minimal nuances. First of all, its shape is defined as an elongated egg due to the characteristic rounded shape of the bottom which tapers gradually upwards. This allows to convey the aromas that are released in the large part in contact with the air left in the glass. It is well known, in fact, that the glass must be filled about 1/3 to leave enough space for the air that acts as a vehicle for the scents that rise towards the nose. However, great discoveries do not arise by chance. They are almost always the result of very specific research and experimentation. In fact, it is due to Jules Chauvet, an esteemed taster and winemaker from Beaujolais, the theory that the relationship between volume and surface of wine glasses is in correlation with the development of aromas. The latter are conveyed towards the narrow mouth in a decisive way to make them reach the nose.
Characteristics of the ISO glass for wine tasting
The dimensions and characteristics of this particular tasting glass, so dear to every enthusiast and professional wine taster, have been codified and registered by the International Standards Organization, hence the initials ISO. To be filled correctly, the wine tasting glass must contain 50ml of wine to describe a perfect hemisphere. in this way, above it, the quantity of oxygen remains sufficient to allow the development of the characteristic scents. The air surface / volume ratio of wine has been studied in order to give priority to the finest and most elegant aromas, leaving behind the so-called ordinary aromas. The ISO tasting glass must be made of transparent glass, absolutely colorless, with the half crystal technique. This means that a lead content of 9% must be included. The total capacity is between 210 and 225 ml. Decorations, inlays and various processes that could distract the taster during the wine evaluation operation are banned.
Accessories for tasting: use and care of the ISO glass
The ISO wine tasting glass is considered to all intents and purposes an iron of the trade for sommeliers and professionals in the wine sector. For this reason, its care must be punctual and rigorous in order to maintain its characteristics unaltered over time. At first use but also afterwards it must not be treated with detergents or soaps. These products, although they can guarantee hygiene and cleanliness, could interfere with wine tasting. Perfumes and residues would pollute the liquid compromising the success of the tasting. Furthermore, the use of soap favors the formation of a film on the walls of the wine glasses that would let the wine slide quickly without the possibility of giving an adequate judgment on its alcohol content and consistency. We must not forget, in fact, that the bows are an essential element of judgment. Therefore, the advice is to use hot water for the first wash followed by a second wash with vinegar in adequate quantity to wet the entire internal surface of the ISO tasting glass. Then, rinse with distilled water or water with a low limestone content. For drying it is advisable to use lint-free linen tea towels. Finally, during the course you have to hold the wine glass with your hand under the cup, avoiding taking it by the stem. This operation could cause twisting with consequent breakage of the tasting glasses.
The world of wine in the showcase
The wine sector fairs and events aim to make sommeliers, enthusiasts and professionals participate in this wonderful world made of sensations, aromas and scents. Vinitaly, Prowine, Salone del Gusto, VitignoItalia, Milan Wine Fest are some examples of annual events that involve an extraordinary number of visitors who have the opportunity to test and taste the most varied wine products. These events can be considered a showcase of the world of wine, whose protagonists are the wine glasses that shine with their own light.
