What is EA in wine?

Ethyl acetate is perceived as the odour of nail polish remover and has a reported sensory threshold of 12 mg/L. Ethyl acetate is the major ester produced by yeast and at low levels can contribute ‘fruity’ aroma properties and add complexity to wine.

Which is derived from fermented juice of grapes?

What is TCA wine?

TCA is an acronym for the chemical compound 2,4,6-trichloroanisole, which is responsible for the aromas and flavors often called “corkiness” in wine or “cork taint,” though if a winemaking team only looks at corks, they will miss many other places it can hide.

VA is often associated with oxidation problems in a wine due to the fact that both result from overexposure to oxygen and/or a lack of sulfur dioxide management. Acetic acid bacteria require oxygen to grow and proliferate.

Why does my wine smell like nail polish remover?

Acetic acid builds up in wine when there’s too much exposure to oxygen during winemaking and is usually caused by acetobacter (the vinegar-making bacteria!). Volatile acidity is considered a fault at higher levels (1.4 g/L in red and 1.2 g/L in white) and can smell sharp like nail polish remover.

What does TCA smell like?

Recent research indicates that TCA itself has no smell, but it appears to suppress olfaction in such a way that presents as dull or moldy odors. Some researchers believe humans are sensitive to cork taint because TCA’s musty smell is similar to mold in food, which could potentially be harmful to us.

What’s the difference between Shiraz and Syrah?

How do you reduce VA in wine?

Ensure that the high-VA wine is sterile filtered before blending. In higher-VA wines (greater than or equal to 0.7 g/L acetic acid), winemakers can use reverse osmosis (RO) to lower the acetic acid concentration. Following RO, the wine can be blended with an uncontaminated and lower-VA wine.
