Just a passing bout of curiosity here. In the movies, they roll a wooden barrel of ale out and it foams up in their mugs.. But how pressure-tight could an oak barrel be? I'd guess the first carbonated beers came about when somebody invented strong enough glass bottles, but that's just picking a guess out of the air. Any historians here who'd know stuff like this?

Carbonation dates back to Ancient Egyptian times, using it from springs where it naturally occurs.In technology circles, it wasn't 'invented' until
1772 by Joseph Priestley by 'impregnating liquids with fixed air (carbon dioxide today)'. However, the egyptians used the carbonated water from the spring (already carbonated), whereas Joseph created the process of carbonating.An oak barrel can be plenty pressure tight. In fact, one of the brewing books gave instructions for making beer 'on the wood'.
