The year 1443 was a catastrophic year for Viennese viticulture. The wine was so extreme angry that even the iron tires of the barrels were allegedly attacked. In Viennese vernacular, the term "Reifbeißer" was created (this name for sour wine is still valid today). The wine could not be drunk and was therefore poured onto the streets. Emperor Friedrich III. (1415-1493) then banned the "pouring away of God's gifts" in severe threats of punishment and ordered the inedible wine to be used to extinguish the lime and produce the mortar during the expansion of St. Stephen's Church in Vienna. But this was more than just a fix, because the addition of wine causes the almost insoluble calcium tartrate (which of course was not known at the time).
As a result, the mortar gains a lot of resistance to damaging chemical influences. Many sources report that the use of wine in making mortar Wien and the surrounding area was a very common practice at that time. In the winegrowing community Falkenstein in the Weinviertel (Lower Austria) there is a wine educational trail. One of the objects on display is a wine barrel on which the tires have cracked. A blackboard mentions the term "tire biter" and the year 1456. The Falkensteiner of this year was also extremely acidic that he might. was also used for a mortar.
