Found some crystalline precipitate in the bottle or cup
So, worried that this wine is fake?
can i drink it?
Today, let’s talk about the sediment of wine
Across the ocean just to meet you, Baxian Guohai Wine Industry, the wine expert around you plj6858
There are three types of precipitation
The first: caused by long-term storage of aged wine
During long-term storage of wine
The pigments in liquor combine with organic components such as polysaccharides and proteins
Formation of colloidal precipitates
it’s thin and black
You don’t have to worry about this kind of precipitation
This means the bottle has a certain age
It should be an old wine!
The second: tartrate pre-cooling crystallization precipitation
The main organic acid in grapes is tartaric acid
Tartaric acid is an important source of acidity in grapes
It is also one of the sources of grape flavor
below -5°C
Tartaric acid easily forms crystals
Both red wine and white wine will have such crystal precipitation

white wine crystal precipitation
Generally speaking, especially during the winter when wine is being shipped north
This precipitation will appear, it is crystalline
Appears on the top, bottom or body of the bottle
The occurrence of this precipitation can at least explain
This is how grape juice is brewed, and the quality is relatively more guaranteed.
The third type: wine lees precipitation
Usually, after wine fermentation is complete
Dead yeast in wine will be filtered out
Later, some winemakers took an unusual path
put dead yeast in a bottle
Yeast lysis releases polysaccharides, amino acids, fatty acids, proteins and other components
The wine is then given its special flavor and complexity during the aging process.
