Germany Flashcards
Germany Climate
- Germany’s main wine-producing regions lie around 49–50°N, making them amongst the most northerly in the world. Overall, the climate is cool and continental.
Germany Growing environment and grape growing (Site selection)
- At this latitude, site selection is essential. Most of Germany’s vineyards are situated along the river Rhine and its tributaries.
- The rivers play a vital role in radiating heat; moderating temperature and extending the growing season.
Germany Growing environment and grape growing (Best sites)
- The best vineyards are often on steep, south- facing slopes to maximum sun exposure.
- Some of the slopes are extremely steep, reaching gradients of 70 per cent overlooking the Mosel.
Germany Growing environment and grape growing (winter, spring summer, autumn)
- Winters can be very cold, usually cold enough for the production of Eiswein.
- In spring, frosts are a major risk, although this is mitigated by the rivers and planting on slopes.
- Summers are warm but also wet; rainfall averages between 500 and 800 mm and much of it falls in the summer. This increases the risk of fungal disease, dilution of grapes and, in heavy storms, hail.
- Autumns, however, are long and dry, allowing for long ripening periods during which grapes can develop the high levels of natural sugar required for Prädikatswein and the morning mists along the rivers are ideal for the development of botrytis.
Germany Growing environment and grape growing (Mountain ranges)
- Also important are mountain ranges, such as the Taunus and Haardt, which shelter the vineyards areas from cold winds and the worst of the rain.
- However, at such high latitudes, vineyards are planted at relatively low altitudes, mainly below 200 metres above sea level.
Germany Growing environment and grape growing (Baden)
- Baden is further south, stretching towards the Swiss border.
- It is noticeably drier, warmer and sunnier than the others, although in cooler areas, spring frosts can still be a concern.
Germany Growing environment and grape growing (SOIL)
- Germany’s vineyards are planted on a wide variety of soils. Soil type plays an important role in fruit ripening in the coolest regions. In Mosel and Ahr, for example, dark-coloured slate retains heat during the day and radiates it out again at night.
- There are significant pockets of calcareous soils.
- In Baden, Pfalz and Rheinhessen, it is planted with Spätburgunder (Pinot Noir), Weissburgunder (Pinot Blanc) and Chardonnay, whilst in Franken, it produces some of the best Silvaner. Grauburgunder (Pinot Gris) prefers heavy, more clayey soils.
- Producers are increasingly interested in how grape varieties, especially Riesling, perform differently and show varying flavour profiles when grown in different soils.
Germany Growing environment and grape growing (SOIL issues)
- On the steep slopes, such as those in the Mosel and Rheingau, erosion is a major problem and vineyard owners are regularly forced to winch soil and rocks back up the slopes adding to the cost of vineyard maintenance.
Germany vineyard management (yield history)
- In 2018, Germany had the seventh largest area under vine in Europe at around 100,000 ha. Average annual production has been around 9 million hL in recent years.
- Yields vary from vintage to vintage and from region to region but, in Rheinhessen and Pfalz, they can average over 100 hL/ha and, in the past, were even higher.
- In the 1980s, due to EU regulations, Germany was forced to impose lower maximum yields but, whilst these vary from region to region, they are still around 150 hL/ha for Deutscher Wein and Landwein, and 105 hL/ha for Qualitätswein
- Quality-minded producers, however, work with much lower yields
Germany vineyard management (Vintage variation)
- Many of Germany’s vineyards are at the northernmost limit for ripening grapes.
- There is considerable vintage variation and, in the coolest years and sites, grapes can fail to ripen fully.
- However, vintage variation has been reducing in recent years. Whilst this is undoubtedly due in part to climate change, there have also been significant advances in vineyard management techniques, led by the various research institutes
Germany vineyard management( techniques that improve fruit ripeness)
- Fruit ripeness has been improved by better clonal selection (especially amongst black grape varieties), summer pruning, green harvesting and selective hand harvesting.
Germany vineyard management( the importance of canopy management)
- Good canopy management is essential to maximise sun exposure and also to improve air circulation in order to reduce the risk of disease caused by the wet summers.
Germany vineyard management(vine training)
- On the slopes, vines were traditionally staked individually with canes tied at the top. However, this method is labour-intensive and requires skills which are gradually being lost and so, as a result of Flurbereinigung, all but the steepest vineyards now use single and double replacement-cane pruning with VSP trellising and Pendelbogen.
Germany vineyard management(Pendelbogen)
- Pendelbogen is replacement-cane pruning with the canes arched in the trellis.
- The arching of the canes is thought to improve the flow of sap in the vine and increase the number of viable buds, in turn increasing yields
Germany vineyard management (organic/biodynamic)
- Germany is not widely suited to organic and biodynamic viticulture. Because of the risk of disease, growers still have to spray their crops regularly
- In Mosel, often the only practicable way to do this is by helicopter and it is likely that sprays would drift onto neighbouring vineyards, risking an organic producers’ accreditation.
- Despite this, around 9 per cent of German vineyards are certified organic. There is considerable support for sustainable viticulture and many estates employ some elements where they can.
Germany vineyard management (mechanization)
- The topography of many German vineyards is also challenging. On steeper slopes, vineyards are terraced or planted up the slopes. Mechanisation is difficult or even impossible and, in some cases, they are so steep that equipment and workers have to be winched up and down.
- Although new technology is being introduced (such as small caterpillar tractors that can negotiate steep slopes), and Flurbereinigung has improved accessibility and efficiency, the steeply sloped vineyards require substantially more labour than flatter sites.
- This increases costs significantly and often only Riesling can command appropriate, sustainable prices.
Germany vineyard management (labour)
- Even on flatter sites, labour costs are often higher than in other wine-producing regions.
- Whilst mechanisation is now widespread, German wine law requires grapes for wines of Beerenauslese level and above to be hand-harvested and many producers still hand harvest for other Prädikatsweine to ensure healthy, fully ripe fruit.
- Large-scale commercial operations producing high-volume, inexpensive wines are highly mechanised and efficient, however.
German grape varieties overview
- Because of the cool climate, German wine production has traditionally been focused on white wine and grape varieties which can naturally tolerate the conditions, such as Riesling, or which have been bred specifically for that purpose
German grape varieties history
- In 1980, 90 per cent of grapes planted were white.
- However, since then, red wine production has increased significantly and, in 2017, 39 per cent of plantings were black.
- Much of Germany’s red wine used to be light and fruity, often with residual sugar but quality has improved greatly, thanks to the development of better clones, particularly of Spätburgunder and Dornfelder, better vineyard management and winemaking techniques, as well as increasing temperatures in the vineyard.
- Since the 1990s, plantings of Grauburgunder, Weissburgunder and, to a lesser extent, Chardonnay have also risen considerably. Otherwise, there are only small plantings of other international varieties, with Merlot, Cabernet Sauvignon and Sauvignon Blanc showing some promise but in very limited volumes.
- Grape varieties need not be stated on German wine labels but usually are.

Riesling vine characteristics
- Riesling accounts for 23 per cent of all plantings. It has proven so successful because it can survive the cold German winters and, being late budding with thick wood, is relatively frost resistant.
- However, it is late-ripening and needs good sun exposure and dry autumns; in cooler years and sites, it may not ripen fully. Because of this, plantings fell in the 1970s and 1980s as producers turned to the more reliable German crosses which could readily achieve the must weights required by law.
- However, improved vineyard management techniques and rising temperatures have led to greater consistency of ripening and plantings have recovered and are continuing to grow.

Riesling wine styles
- Riesling produces high-quality wines in a full range of styles, from dry to sweet. It retains high acidity even when fully ripe, providing balance in sweet wines and giving the wines significant potential for ageing.
- In the right conditions, it can produce high natural levels of sugar and is susceptible to botrytis, making it ideal for producing sweet wines.
- Riesling is capable of making wines with pronounced intensity and great aromatic complexity. Depending on ripeness, fruit flavours range from green fruit to tropical. It can also show floral aromas, such as white flowers or honeysuckle. With age, the wines develop toast, honeyed and petrol-like aromas.
müller-Thurgau vine characteristics
- Müller-Thurgau (sometimes known as Rivaner) was one of the earliest German crosses. Earlier- ripening than Riesling, it can produce high yields in almost any conditions.
- It was Germany’s most planted grape variety in the 1970s and 1980s and was widely used in the production of inexpensive blends such as Liebfraumilch. However, as the popularity of such wines has fallen, plantings have more than halved.
