What is the sediment in the wine bottle?

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.
