A complete and up-to-date ranking list for such wines is difficult to obtain, as the market is constantly changing. Very expensive wines are almost without exception produced on the basis of extremely low yields and with the most elaborate methods, often "handmade", often in small quantities of only a few thousand bottles. The term garage wine is also used for these. For a single 0.75 litre bottle of such absolute top-quality wines one has to pay at least 100 to 200, in some cases up to 500 Euros and for older and/or outstanding vintages up to five and not so rarely ten times that amount. Apart from outstanding quality, historical background or famous previous owners are also important for the high value of a wine bottle. This means that there are collectors who do not purchase such wines at all for the purpose of enjoyment.
