The Mosel wine region is located in the south-west of Germany - and takes its name from the Moselle River which the vineyards are planted along. The area is Germany's 5th largest in volume but is the leading region in terms of international prestige. The region includes the valleys and rivers of Moselle, Saar, and Ruwer near Koblenz and Trier.
The vineyards overlooking the river are some of the worlds steepest, with some at 65° degree inclines, one of the steepest vineyard in the world is the ‘Calmont’ vineyard located near the village of Bremm. The Mosel region is famous for its white wines made from Riesling. The Mosel wine region is continental in location, but is marked by very cool temperatures - so the best vineyard sites have south - southwest facing slopes.

 

Because of the increased exposure to direct sunlight that aid slightly in the ripening of the grapes. The soils in the area are dominated by porous slate which has ideal drainage for the regions heavy rainfall and also relatively good heat retaining properties. During the ripening summer months the weather can be warm, but rarely hot, with the average temperatures in July reaching only 18-20ºC.
The steep slopes along the river are extremely labour intensive - another reason they regarded as some of the worlds most difficult vineyards to manage. Mechanical harvesting is impractical and an extremely high number of man hours are needed to tend the vines, a great more than on flat terrain. Grapevines are individually staked to the slopes without connecting wires so that vineyard workers can move around the vines more easily.
A positive characteristic for working with Riesling - is that in this terroir, it can create a wine of finesse and elegance that would escape most other grape varietals. White grape varietals cover around 90% of the region's total vineyard surface. The wines of the Upper Mosel are characterized by their low alcohol at around 6-9% Alc./vol range with intense fruit driven aromas and lifted acidity.
The wines of the Middle Mosel are considered the most balanced wines of German, some of the countries finest wines - and able to age gracefully for 50-100 years. 
The wines of the Mosel region are traditionally presented in tall green coloured ‘hock style’ wine bottles, this is to distinguish Mosel wines from the 'brown' bottle wines of the Rheinhessen. The Mosel is also well known for its 'Eiswein' production with the area's characteristic high acidity combined with the sweetness produced by the concentration of the sugars in the frozen grapes.
