Siebengebirge (Wine District)
The Siebengebirge wine growing district ("Bereich") is part of the Mittelrhein wine growing region and is made up entirely of the Petersberg site ("Großlage"). The district is named for the Siebengebirge mountain range, located within the municipal boundaries of Bad Honnef and Königswinter. The acreage under cultivation once exceeded 500 hectares, of which today only about 20 hectares remain. Vineyards The site comprises nine vineyards, located in the towns of Niederdollendorf and Oberdollendorf (part of the city of Königswinter), Königswinter proper, Rhöndorf (part of the city of Bad Honnef) and Beuel (part of the city of Bonn). The vineyards of Sülzenberg, Laurentiusberg and Rosenhügel cover the western slope of the Dollendorfer Hardt hill on a soil made up of loam and loess on greywacke. The vineyards of Goldfüßchen, Heisterberg and Longenburgerberg in neighbouring Niederdollendorf have a sandy loam base. The largest vineyards by far are on the slopes of the Drach ...

Vineyards Oberdollendorf
A vineyard (; also ) is a plantation of grape-bearing vines, grown mainly for winemaking, but also raisins, table grapes and non-alcoholic grape juice. The science, practice and study of vineyard production is known as viticulture. Vineyards are often characterised by their ''terroir'', a French term loosely translating as "a sense of place" that refers to the specific geographical and geological characteristics of grapevine plantations, which may be imparted to the wine itself. History The earliest evidence of wine production dates from between 6000 and 5000 BC. Wine making technology improved considerably with the ancient Greeks but it wasn't until the end of the Roman Empire that cultivation techniques as we know them were common throughout Europe. In medieval Europe the Church was a staunch supporter of wine, which was necessary for the celebration of the Mass. During the lengthy instability of the Middle Ages, the monasteries maintained and developed viticultural pract ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Siebengebirge
The (), occasionally Sieben Mountains or Seven Mountains, are a hill range of the German Central Uplands on the east bank of the Middle Rhine, southeast of Bonn. Description The area, located in the municipalities of Bad Honnef and Königswinter, consists of more than 40 hills. The hills are of ancient volcanic origin and came into being between 28 and 15 million years ago. Much of the territory covered by Sieben Hills belongs to the Sieben Hills Nature Park (''Naturpark Siebengebirge''), which is under environmental protection. The highest peak is the Ölberg at 460 metres above sea level. It is a popular tourist destination for hiking, because of its natural environment.

Bad Honnef
Bad Honnef () is a spa town in Germany near Bonn in the Rhein-Sieg district, North Rhine-Westphalia. It is located on the border of the neighbouring state Rhineland-Palatinate. To the north it lies on the slopes of the Drachenfels (“Dragon's Rock”) mountain, part of the Siebengebirge. Overview Bad Honnef is home to a mineral spring called the ("Dragon Spring") which was discovered in 1897. This discovery led to Honnef, as the town was called at the time, transforming from a wine-growing town to a spa town, adding the prefix Bad to its name. The mineral spring has been used for both drinking and bathing. The villages of Aegidienberg, Selhof and Rhöndorf are considered to be part of Bad Honnef. During his term as first chancellor of the Federal Republic of Germany (then West Germany), Konrad Adenauer lived (and died) in Bad Honnef, as it was near Bonn, then the capital of the republic.

Bonn
The federal city of Bonn ( lat, Bonna) is a city on the banks of the Rhine in the German state of North Rhine-Westphalia, with a population of over 300,000. About south-southeast of Cologne, Bonn is in the southernmost part of the Rhine-Ruhr region, Germany's largest metropolitan area, with over 11 million inhabitants. It is a university city and the birthplace of Ludwig van Beethoven. Founded in the 1st century BC as a Roman settlement in the province Germania Inferior, Bonn is one of Germany's oldest cities. It was the capital city of the Electorate of Cologne from 1597 to 1794, and residence of the Archbishops and Prince-electors of Cologne. From 1949 to 1990, Bonn was the capital of West Germany, and Germany's present constitution, the Basic Law, was declared in the city in 1949. The era when Bonn served as the capital of West Germany is referred to by historians as the Bonn Republic. From 1990 to 1999, Bonn served as the seat of government – but no longer capital – ...

Loam
Loam (in geology and soil science) is soil composed mostly of sand (particle size > ), silt (particle size > ), and a smaller amount of clay (particle size < ). By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively. These proportions can vary to a degree, however, and result in different types of loam soils: sandy loam, silty loam, clay loam, sandy clay loam, silty clay loam, and loam. In the , textural classification triangle, the only soil that is not predominantly sand, silt, or clay is called "loam". Loam soils generally contain more nutrients, moisture, and |
Loess
Loess (, ; from german: Löss ) is a clastic, predominantly silt-sized sediment that is formed by the accumulation of wind-blown dust. Ten percent of Earth's land area is covered by loess or similar deposits. Loess is a periglacial or aeolian (windborne) sediment, defined as an accumulation of 20% or less of clay and a balance of roughly equal parts sand and silt (with a typical grain size from 20 to 50 micrometers), often loosely cemented by calcium carbonate. It is usually homogeneous and highly porous and is traversed by vertical capillaries that permit the sediment to fracture and form vertical bluffs. Properties Loess is homogeneous, porous, friable, pale yellow or buff, slightly coherent, typically non- stratified and often calcareous. Loess grains are angular, with little polishing or rounding, and composed of crystals of quartz, feldspar, mica and other minerals. Loess can be described as a rich, dust-like soil. Loess deposits may become very thick, more than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greywacke
Greywacke or graywacke (German ''grauwacke'', signifying a grey, earthy rock) is a variety of sandstone generally characterized by its hardness, dark color, and poorly sorted angular grains of quartz, feldspar, and small rock fragments or lithic fragments set in a compact, clay-fine matrix. It is a texturally immature sedimentary rock generally found in Paleozoic strata. The larger grains can be sand- to gravel-sized, and matrix materials generally constitute more than 15% of the rock by volume. The term "greywacke" can be confusing, since it can refer to either the immature (rock fragment) aspect of the rock or its fine-grained (clay) component. The origin of greywacke was unknown until turbidity currents and turbidites were understood, since, according to the normal laws of sedimentation, gravel, sand and mud should not be laid down together. Geologists now attribute its formation to submarine avalanches or strong turbidity currents. These actions churn sediment and cause mi ...

Drachenfels (Siebengebirge)
The Drachenfels ("Dragon's Rock", ) is a hill () in the Siebengebirge uplands between Königswinter and Bad Honnef in Germany. The hill was formed by rising magma that could not break through to the surface, and then cooled and became solid underneath. It is the subject of much tourism and romanticism in the North Rhine-Westphalia area. History The ruined castle Burg Drachenfels, on the summit of the hill, was built between 1138 and 1167 by Archbishop Arnold I of Cologne and bears the same name. It was originally intended for the protection of the Cologne region from any assault from the south. Originally it consisted of a ''bergfried'' with court, chapel and living quarters for servants. The castle was slighted in 1634, during the Thirty Years' War, by the Protestant Swedes and never rebuilt. As a strategic asset it had outlived its usefulness. Erosion due to the continued quarrying undermined much of the remains and only a small part is left today. The rock, like the ...

Trachytic
Trachyte () is an extrusive igneous rock composed mostly of alkali feldspar. It is usually light-colored and aphanitic (fine-grained), with minor amounts of mafic minerals, and is formed by the rapid cooling of lava enriched with silica and alkali metals. It is the volcanic equivalent of syenite. Trachyte is common wherever alkali magma is erupted, including in late stages of ocean island volcanismMacDonald 1983, pp. 51-52 and in continental rift valleys, above mantle plumes,Philpotts and Ague 2009, pp. 390-394 and in areas of back-arc extension. Trachyte has also been found in Gale crater on Mars. Trachyte has been used as decorative building stone and was extensively used as dimension stone in the Roman Empire and the Republic of Venice. Chemical composition Trachyte has a silica content of 60 to 65% and an alkali oxide content of over 7%. This gives it less SiO2 than rhyolite and more (Na2O plus K2O) than dacite. These chemical differences are consistent with the position ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
