Mayor joined the traditional grape harvest at , the smallest vineyard in Vienna. The site belongs to Weingut Mayer am Pfarrplatz, where owner Hans Schmid and head Thomas Podsednik are managing the 2026 seasonal collection.
The 2026 harvest faces significant challenges, with Schmid expecting yield losses of 25 percent. To save plants, crews manually reduced grape loads on vines. Additionally, the American grapevine leafhopper was sighted in Vienna for the first time this year.
This pest can transmit Flavescence dorée, requiring immediate uprooting of infested vines. President of the Vienna Viticulture Association Norbert Walter noted that drip irrigation is being used to support vines as cellar stocks drop by 30 to 40 percent.
