Climatical conditions(Vinifera)
• High heat summation (at least 1000 degree days with a base of 10oC)
• Sunlight (growth, sugar production, acid reduction) • Good lee conditions• No rain during flowering (June/July) and ripening
(September/October) • Long period with no frost, preferable 150 -180 days
or more (areas near the coast)• Avoid areas with night frost in the spring (‘frost holes’)

Soil conditions• ‘Ordinary Danish agricultural soil’ is OK
(avoid too sandy and too clayish soils)• pH app. 6,5 (certain hybrids a little lower 5,5 – 6) • Deep, well drained soil (deep ploughing / grubning)

Soil conditionsWarm soil:
Advantage: A long growing season – (takes advantage of the bright light in the beginning of the season).Disadvantage: Early budburst increases the risk of damages by night frost.
Fertile soil:
Often a disadvantage because of vegetative growth (little crop) and bad ripening of wood and buds (damage by winter frost). For the same reason: Don’t apply too much N (ca. 50 kg/ha)

Grape varieties• Vinifera (traditional, European varieties)
– Often very susceptible to mildew (Oideum) and downy/’false’ mildew (Peronospora)
– Often difficult to grow (sensitive to climatic conditions)– Not so winter hardy (minus 10-15 oC or maybe a little more)– Makes good wine
• Hybrids (1st generation crossings between V. vinifera and North American and Asian vines – especially V. riparia, V. rupestris and V. amurensis)– Often more resistant to mildew and downy/’false’ mildew– Often easier to grow (more vitality)– More winter hardy– Not permitted in the EU for making quality wine
• Interspecific varieties (back crossings to V. vinifera)– Attempt to combine all the good qualities from both Vinifera and
hybrids (some of these interspecific varieties are permitted in the EU)
![Page 20: Winegrowing in Denmark Winegrower, winemaker and adviser: Peter Lorenzen Bullerupvej 13 DK-5240 Odense NØ Denmark Tel.: +45 66 10 01 67 Mob.: +45 40 31.](https://reader035.fdocument.pub/reader035/viewer/2022062314/56649e8f5503460f94b9279f/html5/thumbnails/20.jpg)

The most grown varieties in Denmark
• Vinifera– Madeleine Angevine (W)– Ortega (W)– Siegerrebe (W)
• Hybrids – Leon Millot (R)– Marechal Foch (R)
• Interspecific varieties– Rondo (R)– Regent (R)– Orion (W)– Perle of Zalas (W) Approved varieties in Denmark
Orion
• Interesting new varieties- Solaris (W)- Acolon (R)- Bolero (R)- Reberger (R)- Cabernet Cortis (R)
W = White R = Red

November 2006 Peter Lorenzen 21
Rootstocks• Primarily to avoid attacks from the root aphid
(Phylloxera)
• It also affects the growing conditions of the vines: Budburst, earliness, ripening of the wood etc.
• There is a great need in Denmark for trials in growing different rootstocks in different soils (and on different varieties)
• Common rootstocks in Denmark are– SO4– Börner– 125AA– 5BB Approved rootstocks in Denmark
Interesting ’new’ rootstocks:

November 2006 Peter Lorenzen 22
Pests and diseases• Fungal diseases
– Mildew (Oideum)– Downy or false Mildew
(Peronospora)– Grey Mould
• Pests– Phylloxera (grafting)– Deer (fencing)– Hares (plant tubes) – Water vole– Birds (netting) – Wasps (traps) – Snails
• Other damages– Rot (grey rot)
– ‘Hens and chickens’ – Stem necrosis – Frost damages (bud
necrosis) – Lack of nutrition
(especially magnesium) – Draught damages – Spraying damages – Hail – Cracks in the berries – Night frost in the spring

Commercial winegrowing in DK
• Approved by the EU in August 2000• Today around 25-30 registered, Danish winegrowers• Area: Around 15-20 ha (permission to plant 99 ha – like
Sweden and Ireland)• 8 Danish winegrowers had wine for sale in 2004 (app.
5000 litres in all).• In 2005 10 -12 winegrowers are expected to produce
around15.000 litres of wine in all.• 2006 is going to beat all records. • Read more (in Danish) at http://www.vinavl.dk/
o In Sweden I know of three commercial winegrowers• Read more (in Swedish): www.svenskavinodlare.se
o As far as I know, Norway has no commercial vineyards (any more)?

LegislationCouncil Regulation (EC) No 1493/1999 of 17 May 1999 - on the common organisation of the market in wine
Danish rules:
Three categories of wine:
• Table wine (Vin de table, Tafelwein, Vino da Tavola etc.)
• Table wine with geographical indication (Vin de pays, Landwein, Indicazione geografica tipica, Regional wine etc.)
• Quality wine (AOC, QmBA, DOC etc.)

November 2006 Peter Lorenzen 25
Vintage
• Data from the Danish vintage reports– Up to app. 1 kg/m2 in good years– Corresponding to 10 tons pr. ha = app. 4000 litres of wine
(around 5000 bottles)
• Rule of thumb under Danish conditions:– One to two bottles of wine pr. vine– Corresponding to 3.000 to 6.000 bottles pr. ha in good years
• In the year 2004 only 5 – 10 % yield !!
