The origins of wine-growing in Dainbach certainly date back to the early Middle Ages. Wine-growing in Dainbach was revitalised by the founder of the Roto company, Wilhelm Frank, who comes from Dainbach. As a result of his efforts, new vines of the Müller-Thurgau and Gutedel grape variety were planted at the start of the 1970s at the “Dainbacher Alte Burg” (Old Dainbach Castle) site. From the start of the 70s to the beginning of 2001, these vineyards were processed solely by his company. Since 2002, these vineyards have been leased to a young viniculturalist from Gerlachsheim.
The entire vineyard now covers the “Dainbacher Alte Burg” site (3.3 ha), which is wholly owned by the company. This area is planted with 1.3 hectares of the Müller-Thurgau grape variety, 1.14 hectares of the Grauer Burgunder, 0.6 hectares of the Schwarzriesling, 0.15 hectares of the Tauberschwarz and 0.1 of the Gutedel grape varieties. The wine produced from there is bottled in Bocksbeutel and wine bottles by neighbouring Becksteiner Winzer eG and can also be bought from there, among other places.
