This work deals with the anaerobic treatment of grape marcs. In this work we tested two varieties of wine. Veltlínské zelené and Zweigletrebe. Tests were carried out in the Republic reference laboratory at Mendel University in Brno under mesophilic anaerobic conditions for 24 days in 0.003 m3 reactors and for 26 day in 0.120 m3 reactors. Biogas production and methane content were monitored daily during the test. The measurement results of testing variety Veltlínské zelené were: Substance loads ratio 0.496 kg.kg-1 - specific production of biogas 0.415 m3.kg-1, specific production of methane 0.246 m3.kg-1 and average concentration of methane in biogas was 59.3%. Substance loads ratio 0.099 kg.kg-1 - specific production of biogas 0.656 m3.kg-1, specific production of methane 0.262 m3.kg-1 and average concentration of methane in biogas was 39.8 %. The measurement results of testing variety Zweigeltrebe were: Substance loads ratio 0.496 kg.kg-1 - specific production of biogas 0.378 m3.kg-1, specific production of methane 0.234 m3.kg-1 and average concentration of methane in biogas was 61.9 %. Substance loads ratio 0.095 kg.kg-1 - specific production of biogas 0.544 m3.kg-1, specific production of methane 0.262 m3.kg-1 and average concentration of methane in biogas was 48.9 %.
