What percentage of Germany’s vineyard area is Riesling?
Nearly 25%
What country is the world’s largest producer of Riesling?
Germany
What is Liebfraumilch?
Inexpensive, medium sweet wines produced from Muller-Thurgau and Kerner, specifically developed to produce high yields of ripe grapes in the cold German climate. Accounted for 60% of all German wine exports by the 1980s but has since plummeted
What important vineyards in Germany were planted in the 12th century?
Schloss Johannisberg and Kloster Eberbach (both in the Rheingau)
What caused the German wine industry to decline in the 17th century?
The 30 years war, which saw the flat valley plains where vines were planted torn up for grain production, pushing vineyards onto the steeper slopes
What is the basis for German wine laws, and when was this introduced?
Must weigth of grapes, introduced in the 1830s
When did Germany become a unified country?
1871
What happened to the German wine industry between 1895 and 1945?
Area under vine halved due to phylloxera, mildew, then the world wars. It has more than doubled since
What post-war changes took place in the German wine industry? What was this called?
Emphasis on bulk production of reliably ripe grapes, like Muller-Thurgau, sourcing from multiple regions to ensure volume, and a major program of vineyard restructuring that consolidated fragmented sites, built access roads, and made mechanization possible (called Flurbereinigung)
When was the 5th German wine law passed, and what did it do?
1971, laying the foundation for modern German production based on protected geographical labeling and classification of styles based on must weights
Where do the bulk of Germany’s wine-producing regions lie?
49-50’N, making them some of the mot northerly in the world
What is the overall climate of German wine country?
Cool continental
What factors influence site selection in Germany?
Most vineyards are along the Rhine and its tributaries, which radiate heat, temperature, and extend the growing season. Best vineyards on steep, south-facing slopes for max sun exposure. Some reach 70% grade
What are the main viticultural threats in Germany?
Frost (although mitigated by rivers and slopes), and wet summers that increase fungal diseases, dilution, and sometimes hail
What role do mountain ranges play in German viticulture? What are the main ranges?
Taunus and Haardt mountains shelter vineyard areas from cold winds and the worst rain (although vineyards are relatively low, usually below 200M)
What is different about Baden’s climate compared to the rest of Germany?
More southerly, toward the Swiss border, and is noticeably drier, warmer, and sunnier (although cool areas still have frost risk)
What role does dark slate soil play in German viticulture? Where is it found?
Slate retains heat during the day and radiaties it out at night, helping ripening in the Mosel and Ahr
Where are calcareous soils found in Germany, and what is planted in them?
Baden, Pfalz, and Rheinhessen, where it is mostly planted to Spatburgunder (PN), Pinot Blanc, and Chardonnay, and Franken, where it produces Sylvaner
What unique expense is incurred in steep slope vineyards of Germany, and where is this most common?
Steepest sites in Mosel and Rheingau have such major erosion problems that owners must winch soil and rocks back up the slopes
How many hectares are there under vine in Germany? Where does this rank in the EU?
100,000 ha, 7th in the EU
What are the maximum yields for Deutscher Wein, Landwein, and Qualitatswein?
Varies by region, but typically 150 hl/ha for Deutscher Wein and Landwein, and 105 hl/ha for Qualitatswein
Besides climate change, what has contributed to reduced vintage variation in Germany?
Better clonal selection (particularly with black grapes), summer pruning, green harvesting, and selective hand harvesting
What is Flurbereinigung?
The program of modernization and mechanization Germany undertook in its vineyards after WW2
Why is canopy management so important in Germany?
It is essential for maximizing sun exposure and ensure air circulation (to reduce disease pressure)
