is there any relationship between grass and wood biomass.
i have successfully generated methane gas from grass and am thinking of extending my effort to use it as an alternative fuel for smoking fish in Ghana. But the flavour presented by the smoked fish as a result of using the firewood to smoke the fish is not evident when the methane gas is used for the smoking.
Am wondering if it is necessary to experiment to find out whether a particular grass species can have a characteristic chemical composition to a particular wood or tree species in terms of the flavour; despite the higher amount of fibre in wood.

The flavor added to meat from using wood to barbecue or smoke comes from incomplete combustion of carbon. The chemicals produced include polycyclic aromatic hydrocarbons. If you are trying to cook using the methane produced from the fermentation grass you will not get a smokey flavor because of the pretty thorough combustion. I suppose you could smoke the fish using the dried grass an generate some smokey flavor from the incomplete combustion of the grassy biomass.
