Wine contains natural preservatives such as tannin, sugar and alcohol, [2] and can be preserved through physical preservation methods, such as storage at an appropriate temperature. [3] However, bacterial growth is still possible, so chemical preservatives are added to most wines.
Wine is very susceptible to changes in temperature, with temperature control being an important consideration in wine storage. If the wine is exposed to too high a temperature (in excess of 77 °F (25 °C)) for long periods of time, it may be spoiled or become "corked" and develop off-flavors that taste raisiny or stewed.

Says Stewart of his chosen method, “As the owner of a busy wine bar where we typically open a few dozen bottles of wine a night, wine storage is extremely important. After quite a bit of ...
Biogenic amines have been implicated as a potential cause of red wine headaches. In wine, histamine, cadaverine, phenylethylamine, putrescine, and tyramine have all been detected. These amines are created by the degradation of amino acids found in grape must and left over from the breakdown of dead yeast cells after fermentation.
Ethanolamine (2-aminoethanol, monoethanolamine, ETA, or MEA) is a naturally occurring organic chemical compound with the formula HOCH 2 CH 2 NH 2 or C 2 H 7 NO. [8] The molecule is bifunctional, containing both a primary amine and a primary alcohol.
A wine fault or defect is an unpleasant characteristic of a wine often resulting from poor winemaking practices or storage conditions, and leading to wine spoilage. Many of the compounds that cause wine faults are already naturally present in wine but at insufficient concentrations to adversely affect it.
A glass of red wine. The health effects of wine are mainly determined by its active ingredient – alcohol. [1] [2] Preliminary studies found that drinking small quantities of wine (up to one standard drink per day for women and one to two drinks per day for men), particularly of red wine, may be associated with a decreased risk of cardiovascular diseases, cognitive decline, stroke, diabetes ...
