Czech wine law classifies wine according to the origin of the grapes and the ripeness of the grapes determined by measuring the must weight in the grape juice at the time of harvest.
Sugar content is expressed in units of °NM on the Czecho-Slovak Normalised Must-Weight Scale "Normalizovaný moštoměr", which indicates how many kilograms of sugar are contained in one hundred litres of grape juice. One degree on the NM scale is equivalent to one kilogram of natural sugar in 100 litres of grape must.
Czech wine is typically labeled with its variety, detailed description of its origin, and wine quality attributes.
In general, wine produced from grapes with a higher must-weight level and from a single vineyard is considered higher quality.
MORAVIA "Vinařská oblast Morava"
This region stretches from the southernmost point of the Morava (March) river up as far as the area lying to the west of Brno. Altogether you will find here almost 96% of the total of registered vineyards in the Czech Republic. With a view to the prevailing climatic and geographical conditions the ripening of grapes takes place at a slower rate. That is why a larger amount and greater diversity of the aromatic substances are concentrated in them.
The Moravian Wine Region is divided into four sub-regions
Velké Pavlovice sub-region
BOHEMIA "Vinařská oblast Čechy"
Bohemia is home to a relatively tiny collection of vineyards that are among the most northerly in Europe. They are situated around 50° north latitude, the same as Wiesbaden in the Rheingau.
The Bohemian Wine Region is divided into two sub-regions
A Czech wine label will typically specify the wine's origin with one or more of the following terms
Wine Region "Vinařská oblast" - Moravia "Morava", Czech "Čechy"
Subregion "Vinařská podoblast" - e.g. "Velkopavlovická"
Wine Village "Vinařská obec"
1. QUALITY WINE WITH SPECIAL ATTRIBUTES
"Jakostní víno s přívlastkem"
These are the highest gualy wines. They must originate from a single wine subregion and the grape varieties, their origin, must weight levels, and weight must be verified by the Czech State Agricultural&Food Inspectorate
(SZPI). Chaptalisation is not permitted.
2. QUALITY WINE "Jakostní víno"
Wine produced from grapes grown in the Czech Republic within a single wine region. Yields must not exceed 12 tons/hectare and must-weight levels must be no less than 15 °NM.
Quality Varietal Wine "Jakostní víno odrůdové"
Wine made from at most three grape varieties
Quality Brand Wine "Jakostní víno známkové"
Wine that is a blend (cuveé) of at least two grape varieties
3. COUNTRY WINE "Zemské víno"
Wine produced from grapes originating from the Czech Republic, must-weight levels must be no less than 14 °NM.
4. TABLE WINE "Stolní víno"
Wine produced from grapes originating from any country in the EU. This is the lowest wine category.
CATEGORIES ACCORDING TO THE CONTENT OF RESIDUAL SUGAR
A wine which fermented to dryness and its residual sugar content is not exceeding:
max. 4 g residual sugar per litre or
max. 9 g residual sugar per litre should the difference in residual sugar and the total acidity content converted into tartaric acid be 2 grams or less.
To be labelled as a semi-dry wine it must contain:
max. 12 g residual sugar per litre or
max. 18 g residual sugar per litre should the difference in residual sugar and the total acidity content converted into tartaric acid be 10 grams or less.
The residual-sugar content in the wine is greater that the highest value stipulated for semi-dry wines, but reaches a maximum of 45 g per 1 litre.
According to the legislative regulations this is a wine with a residual-sugar content of at least 45 g per litre.
QUALITY AND ECOLOGICAL
During the course of the past 20 years wine production in the Czech Republic has been transformed significantly. Winemakers have bought and started to employ the most modern technology available, aimed strictly at improving the quality of wine as opposed to just achieving the greatest possible quantity, and also made a great stride forward to adopting environmentally friendly viti-vinicultural practices. One can find a huge range of organic wines and organic vineyards, but even the majority of other (non-organic) winemakers take great pains to approach the cultivation of their grapes and the production of their wine in the most ecological way. For instance, they keep the use of chemicals to the absolute minimum and the production of grapes and the wines made from them in the Czech Republic are almost totally ecological.
