Why does soy sauce liquor turn yellow, and is yellowing necessarily good wine?

Why soy sauce white wine color will turn yellow?

First of all, we have to be clear that the yellowing of white wine is more complicated, it is closely related to the raw materials of wine, brewing process, storage time and environment and other factors. The situation is not the same for different flavors, not all flavors of white wine will turn yellow.

There are three main factors that contribute to the yellowing of white wine:

1, the wine inside the acid ester ketone and other aroma substances of the role of color.

There are some subtle reaction changes in the brewing of white wine, so that the wine body contains, alcohols acids, esters, ketones and other main aroma substances, such as: lactic acid ethyl ester, ethyl acetate, acetic acid, malic acid and other compounds, these ketone compounds are varying degrees of yellow color, which makes the wine body color with yellow. The yellow color at this time is the beneficial performance of good wine.

2, after the volatilization of alcohol coloring.

White wine storage process, the body of the slow and complex chemical changes occurring within the aldehydes and ketones to increase the content of compounds, so the longer the soy sauce-type white wine storage time, the more obvious this presentation reaction will also be the more yellow the color of the wine. Therefore, there is a folk saying that the older the wine, the more yellow it will become. This yellow color is also a beneficial manifestation of good wine.

3, the sediment in the white wine to make the body of the wine is contaminated discoloration.

There are trace impurities in the wine such as suspended solids, however, these impurities are not visible to the naked eye for some time, only causing a slight color change. For example, white wine in contact with iron containers can cause yellowing, turbidity and precipitation, which occurs due to rust soaking into the wine. This yellow color is not needed for good wine.

Now micro-yellow is not the only standard of good old wine, we are looking for quality soy sauce wine when you have to pay attention to the scam, now a lot of unscrupulous merchants in the white wine to add pigment to increase the yellow, I hope you do not just to see the color.
