Interesting video.
If I remember correctly, Louis Pasteur studied tartaric acid, and discovered its optical isomers.
Thank you.

Potassium bitatrate deposits on the barrel or tank when you cool down the wine sufficiently, tartaric acid and potassium are present in grapes in naturally large quantities. Cold stabilizing white wine is typically when you would create a lot of tartrate crystals in the vessel

thanks for that - biggest/thickest piece of tartrate deposit i've ever seen. These are usually small like sand particles. This is crystal growth. i searched and found your video because i have a barrel of wine which needs acid reduction from tartrate formation and i'm looking for how to encourage it. so far, i think i will add some seed crystals to the barrel so it can start forming from those. i think you can add depth to your video by combining to add quick opinion by winemaker. thanks for showing that big crystal!

It's Louis Pasteur that discover tartaric acide is optically active. But Pasteur didn't discover vaccine. He was chemist not biologists

The optical isomerism of tartaric acid were indeed discovered in wine, by none other than the great chemist Pasteur!

as a material of fact, red wine is a buffer solution because of the salts and acids in it and that is why drinking moderately wine with foods It helps digesting the meals.

Miguel Ángel Simón Fernández

tartaric acid salts, bitartrates, must be precipitated to stabilize wine. this is usually done by cooling to reduce solubility

KC4H5O6, Cream of tartar, plus sugar, plus vanilla, boiled together, forms the syrup combined with carbonated water to make cream soda. You can buy the cream of tartar cheaply at "organic" food places that sell walnuts, dried fruit, teas, etc., by the scoop. Or buy it in the spice aisle if you want little jars that cost a mint. This is also a decent way to clean aluminum pots and pans and make meringues stiffen better.

I don't know if tartaric acid was discovered first in wine, but it the german name for it is 'Weinsäure' - which means 'wine acid'.

Tartaric acid is the main acid present in wine. Grapes are a little bit different from other fruits since they stores mainly tartaric acid, and other fruits stores malic and citric acid. So as it ferments, the grape juice has about 5 to 8 gr/l of tartaric acid. That acid reacts with potassium also in the juice and creates potassium tartrate, that precipitates in crystals and form that kind of lumps in wine barrels and vats. The one professor has probably was formed in many years of wine storage.

Sediment in wine should be more pottasium hydrogen tartrate (also called "wine stone") than the tartaric acis itself.

rtpoe 2 months ago

Tartaric acid is present in grapes in significant amounts. When the juice is fermented, the potassium acid salts (tartarates) bind with the various particulates in the juice and settle out or crystallize. It's a normal part of the fermentation process. Winemakers even add tartaric acid to the wine to adjust the flavor balance.

I am a gardener and I have a Concord grape arbor. In juicing grapes, you have to heat up the grapes, filter the pulp in a strainer and a juice bag and let the juice settle in the refrigerator overnight. You had to carefully skim the juice off of the top for juice or jellies. The sediment on the bottom of the vessel you had the juice in is mostly tartaric acid with the fine pulp mixed in. Tartaric acid (cream of tarter) powder mixed with an equal amount of baking soda (Sodium Bicarbonate) is a simple baking powder for leavening biscuits and such. Grape juices and jellies have a little in it. My frozen Popsicles made from the bottom of a batch had too much tartaric acid in them. Eating one of those popsicles after supper caused a very painful gastritis the next morning. Eating too much tartaric acid will irritate your duodenum and cause bile to back into your stomach. Not pleasant.

Tartaric Acid is often times harvested and used in baking. Can be used as a leavening agent but is less effective than sodium bicarbonate (baking soda).

Tartaric acid is almost the last step in the krebs cycle. It also has a highly suspected link to neurological disorders in youth.
Generally you can fix it by supplementing with malic acid but then your just covering up whats really wrong.

When Jesus turned water into wine did he remember to add tartaric acid and if so, where did he get the carbon atoms from? This whole miracle business is starting to sound a bit fishy to me, to be honest! haha.

And yeah, this would be potassium hydrogen tartarate, which is rather insoluble. (Also known as cream of tartar.) Actual tartaric acid will easily concentrate into a syrup before crystallizing.
