Mikulovská wine grown in Mikulovská than any other Moravian region. The most planted red varieties are Saint Laurent ("Svatovavrinecké", 310 ha), Blaufränkisch ("Frankovka", 248 ha), Zweigelt ("Zweigeltrebe", 181 ha), and Pinot noir ("Rulandské modré", 172 ha). Plantings of Blauer Portugieser ("Modrý Portugal", 92 ha) has decreased rapidly, while Cabernet Sauvignon (89 ha) has increased. The Czech Wine Classification System, set in the Viticulture Act of 2004, is based on the sugar content of the grapes at harvest. Sugar content is measured using the Normalizovaný moštomer (°NM) scale, a measure of how many kilograms of sugar are in 100 litres of must. 1
Ripeness in viticulture .75 TA will have almost a 30:1 Brix:TA ratio. According to the Davis researchers, the most balanced table wines tend to have a Brix to TA ratio between 30:1 - 35:1. Another method is to multiply the pH reading by itself and then multiply that number by the Brix reading. Using this method, when white wine grapes gets close to 200 and red wine grapes close to 260, it can be a good rule of thumb of when to harvest. For example, white wine grapes have a pH of 3.3 and Brix of 20, after going through that formula they
