Is the process fermentation can produce methane?

Answer 1

Not usually. Fermentation by yeast usually involves the breakdown of glucose into carbon dioxide and ethanol (alcohol). This is an anaerobic method of obtaining energy used by the yeast. If the yeast are exposed to larger amounts of oxygen they switch to aerobic respiration and produce acetic acid (vinegar) instead.

If your fermentation is producing methane then I would guess that your fermentation process has been contaminated by a fungus or bacterium

Answer 2

its produces ethyl alcohol methane gas is produced when things rot

Methanogenesis or biomethanation is the formation of methane by microbes. This is an important and widespread form of microbial metabolism. In most environments, it is the final step in the decomposition of biomass. (from wikpaedia)
