A large Kvevri held at the Georgian National Museum of Tbilisi. Kvevri or Qvevri (Georgian: ქვევრი [ˈkʰvɛvɾi]) - also known as Ch'uri (Georgian: ჭური [ˈtʃʼuɾi]) in Western Georgia - are large earthenware vessels used for the fermentation, storage and aging of traditional Georgian wine.
Wine is a complex mixture of chemical compounds in a hydro-alcoholic solution with a pH around 4. The chemistry of wine and its resultant quality depend on achieving a balance between three aspects of the berries used to make the wine: their sugar content, acidity and the presence of secondary compounds.
The excavations of the winery were completed in 2010. The winery consists of fermentation vats, a wine press, storage jars, pottery shards, and is believed to be at least a thousand years older than the winery unearthed in the West Bank in 1963, which is the second-oldest currently known.

In this process the wine is drained into a secondary vessel, allowing the cap to settle to a bottom and loosen the seeds that are trapped in the pulps. As the wine drains, a filter captures the seeds and removes them from the wine. The wine is then returned the first vessel. Demi-muid A large oak barrel that holds 159 gallons (600 liters). In ...
In surface filtration, the wine passes through a thin membrane. Running the wine parallel to the filter surface, known as cross-flow filtration, will minimize the filter clogging. The finest surface filtration, microfiltration, can sterilize the wine by trapping all yeast and, optionally, bacteria, and so is often done immediately prior to ...
The Speyer wine bottle (or Römerwein [1]) is a sealed vessel, presumed to contain liquid wine, and so named because it was unearthed from a Roman tomb found near Speyer, Germany. It contained the world's oldest known liquid wine (dated to about AD 325), until 2024, when a 1st century AD urn within a Roman tomb - found in 2019 in the southern ...
Buckminsterfullerene (C 60) and the 60 atoms of this molecule are arranged in a cage-like structure and the framework resembles a soccer ball; the molecule has an icosahedral symmetry. [ citation needed ] C 60 has versatile applications due to its macromolecular cage structure; for example, it can be used for water purification, catalysis, bio ...
Thus, the wine-water mixture would be withdrawn from the krater with other vessels, such as a kyathos (pl.: kyathoi), an amphora (pl.: amphorai), [1] or a kylix (pl.: kylikes). [1] In fact, Homer 's Odyssey [ 2 ] describes a steward drawing wine from a krater at a banquet and then running to and fro pouring the wine into guests' drinking cups.
