German wine is primarily produced in the west of Germany, along the river Rhine and its tributaries, with the oldest plantations going back to the Roman era. Approximately 60 percent of German wine is produced in the state of Rhineland-Palatinate, where 6 of the 13 regions (Anbaugebiete) for quality wine are situated. Germany has about 103,000 hectares of vineyard, which is around one tenth of the vineyard surface in Spain, France or Italy. The total wine production is usually around 10 million hectoliters annually, corresponding to 1.3 billion bottles, which places Germany as the eighth-largest wine-producing country in the world. White wine accounts for almost two thirds of the total production.
Steep vineyards on Rüdesheimer Berg overlooking the river Rhine. These vineyards are located in the southwestern part of the region Rheingau at a bend in the river. These vineyards are planted with Riesling grapes, with some Spätburgunder (Pinot noir), and produce some of the finest wine in Germany.

Vine trellising according to the Pfälzer Kammertbau system traditional to the Palatinate, where it was widely used until the 18th century. In an all-wooden version (without the steel wires), this system is supposed to date back to Roman times.

In viticulture, ripeness is the completion of the ripening process of wine grapes on the vine which signals the beginning of harvest. What exactly constitutes ripeness will vary depending on what style of wine is being produced and what the winemaker and viticulturist personally believe constitutes ripeness. Once the grapes are harvested, the physical and chemical components of the grape which will influence a wine's quality are essentially set so determining the optimal moment of ripeness for harvest may be considered the most crucial decision in winemaking.

Pinot noir grapes in the early stages of veraison. As the grapes ripen, the concentration of phenolic compounds like anthocyanins replaces the green color of chlorophyll in the grape berries which makes them black instead.
Pinot noir grapes that are destined for sparkling wine will be considered ripe much earlier than Pinot noir destined for still red wine.
Vineyard management techniques such as canopy management can influence the ripening process of grapes by balancing the amount of foliage needed for photosynthesis versus excessive foliage that shades the grapes and competes for the grapevine's resources.
