The estate is located in the municipality of Retzstadt (Maindreieck area) in the German wine-growing region Franconia. Own wines have been developed since 2004, although the family has had its own vineyards for over three generations. By linking the family production companies to the "Koch family of vintners", Andreas Koch has managed to put together a manageable range of wines. The vineyards in the Retztal and adjacent Maintal comprise five hectares of vineyards in individual layers Benediktusberg (Retzbach), Langenberg (Retzstadt) and stone (Stetten). They are predominantly with the white wine varieties Silvaner, Müller-Thurgau, Rieslaner, Kernling and Pinot Gris ( Pinot gris ), as well as with the red Pinot Noir varieties ( Pinot Noir ), Black Riesling ( Pinot Meunier ) and Domina planted. The management is carried out in a conventional, environmentally friendly manner according to the philosophy of the house "in harmony with nature".
As a certified Slow food producer the company pays particular attention to varietal and Parcels -Typicity placed. The wines are fermented partly chilled or with Yeast storage (sur lie) expanded. The red wines, however, mature in Barrique or in large wooden barrel. The wines are produced in the three lines "New Franconia", "Classic Franconia" and "Exotic Franconia". Premium wines include QUERICUS Benediktusberg Spätburgunder Spätlese dry, Langenberg Rieslaner Spätlese dry and Langenberg BAROCK Silvaner Spätlese dry. Around 12,000 bottles of wine are produced annually. The company also offers services related to wine and nature. Senior head Monika Koch is a trained tour guide for the Franconian Wine Experience and organizes guided vineyard hikes with a tasting "Experience wine where it grows". Andreas Koch is part of the Generation Riesling young wine association.
