Bulgarian wine exports rose by an annual 16% to 25.14 million litres in the first half of 2012, the agriculture ministry said.
Sales of Bulgarian wine on the domestic market amounted to 46.96 million litres in the January-June period, up by an annual 13%, the ministry said in a statement on Tuesday.
In the first six months of the year Russia, Romania, Poland and the Czech Republic were the country's main foreign markets for wine.
The 2012 grape harvest is expected to be 30% lower than a year earlier due to low winter temperatures and prolonged drought during the summer months. The quality of the grapes, however, is high, the statement added.
Bulgaria produced a total of 105 million litres of wine last year. The country exported some 65.6 million litres of wine in 2011, with Russia being the biggest foreign market.
