Atypical Aging (ATA) was first detected in Germany in 1988 in the wine growing area in Franconia. Thereafter, in all the German wine growing regions ATA was expressed more or less severe. It was detected in all white wine varieties and also in Ros? wines, but never in red wines. Mainly it was found in light wines, like base wines for sparkling wines. In over-cropped vineyards and in such with a low water table, that means on dry sites. Looking around whether this phenomenon is a solely German problem, it quickly became clear, that this unpleasant odor defect can be found around the world. In Europe ATA has been detected so far in Austria, Switzerland, Italy, and France. But also it has been found overseas. In wines from the Finger Lakes it has been recognized for several years, but it was not taken into account as a separate fault. Originally it seen as a fault coming from mixing native American or American-French hybrid wines into a vinifera wine. But California, Oregon, Australia, New-Zealand and South Africa experience this defect. If some more countries would show the fault in their wines, it would not be surprising.
