Potassium bitartrate
From EncycloWine
Potassium bitartrate is a byproduct of winemaking. It is also known as "cream of tartar". It is a potassium acid salt of tartaric acid.
Potassium bitartrate crystals found in wine bottles that have been subjected to cold temperatures. The cold treatment process usually applied to white and rosé wines is mainly aimed at precipitating this salt.
tartrates: Potassium bitartrate is an insoluble by-product of tartaric acid. It can form as a harmless but aesthetically undesirable crystalline deposit in bottle.
Authentic port is from the Douro River Valley of Portugal.
Potassium bitartrate
The crystals that sometimes precipitate in bottled wine, but which are normally removed by cold-stabilization. Made of the same compounds as Cream of Tartar.
These Potassium Bitartrate crystals, or Cream of Tarter, are harmless, and do not affect the flavor of the wine.
COLOR-RED WINES - When young, many red wines have significant proportions of blue coloration, making them appear purple.
This process removes excess tartaric acid that, if untreated, might later form potassium bitartrate crystals, which can show up in wine bottles or on corks.
Once the isoelectric pH of tartaric acid is reached and continues to increase, the bound tartaric acid becomes free tartaric acid (H2T-) which changes into potassium bitartrate (HT-) which, in turn, ...
This process removes excess tartaric acid that may form potassium bitartrate crystals, which can show up in bottled wine or on corks.
This comes from the harmless crystals of potassium bitartrate (cream of tartar in the spice section of the grocery store) which precipitate out of the wine when the temperature is dropped.
Crust - Sediment, generally potassium bitartrate, that adheres to the inside of a wine bottle.
Cult wines - Wines for which committed buyers will pay large sums of money because of their desirbility and rarity.
Beeswing
A light potassium bitartrate sediment, mostly found in Port.
Bentonite
Bentonite is a type of clay hat can be used as a fining agent and wine clarification.
Harmless crystals of potassium bitartrate that may form in cask or bottle (often on the cork) from the tartaric acid naturally present in wine.
Terroir ...
Potassium also exists in grapes, and when these two things bind together under chilly conditions, they form little potassium bitartrate crystals, which then settle to the bottom of the bottle. They're completely harmless, and quite natural.
Components of tartaric acid, including potassium bitartrate and cream of tartar, they are less soluble in alcoholic solutions than in grape juice and solidify at cooler temperatures (such as those found in a refrigerator); ...
The perception of creaminess is generally picked up at the back of the throat and through the finish of the wine.
