In-line with earlier statements, I'd say no blasts or bombs through ignition with flint and steel. Not even from a torch. Ignition through fire-spread may cause a barrel to heat up to sufficiently high temperatures and cause explosive mixtures to form in significant, combustible quantities. Nonetheless, the explosions from such barrels shouldn't exceed those of normal orc bombs. I'd say make fire spread able to cause a barrel with more than 5% ethanol to ignite and cause a minor blast. Only fire-spread! No blast - blast propagation! It takes ethanol to evaporate and mix with oxygen in proper concentrations to get an explosive gas mixture. Too high ethanol concentration even cancels out explosivity, but for the sake of simplicity and gameplay fun, I'd say forget about upper explosion limits ...

For reference, see this post for the original notion of blowing barrels through fire-spread:
