What is ullage?
ullage is a medium English word that means "space in the upper part of the barrel, bottle or barrel." It is used in a wide range of industries to refer to either a liquid that is missing from a container or to a space that remained this missing liquid. This term usually occurs in the evaluation of wine bottles in which Ullage can be a critical factor in determining quality and cost, especially in older bottles of wine.
The roots of this word are quite interesting. Ullage is derived from the Latin oculus , "eye", the term that was borrowed to refer to the bunghole in the barrel. The French accepted this word as ouiller , "fill the barrel" and the Normans brought him to England as "Ullage" who used it to refer to the level of barrels to Bunghole. Finally, Ullage came to refer to an empty space in any kind of container, from a bottle of juice to a rocket.
Ullage is critical in the wine. Ullage happens over time when wine in a bottle of pomThe alu evaporates and the level of ullage can change radically if the wine is poorly treated or cork is defective. Ullage is usually described in terms of shoulder and neck of the bottle. Many new wines are filled to the neck, while Ullage slowly slips around the shoulder over time. Looking at the lists of old wines for sale, you may have noticed the "Ullage" links that the buyers use to get some tracks into a state of wine and cork.
If ullage in a bottle of wine is significant, it can support oxidation, causing the wine to go out. For this reason, wine barrels and bottles must be completed regularly, ensuring that the wine level remains high. Some wineries offer a recording service in older years, allowing consumers to bring wine bottles so that their cork can be removed and the bottle can end with storage.
6 For this reason, it is good to check the wine in the store before purchasing and assess Ullage. When purchasing older years, ullage should always be considered and if it isUllage high, the seller should be asked if the wine ended. Oxidation prevents the culmination, but it can also affect the taste of the wine and its value.
