I use air-tight and nuke-proof surplus explosive projectile cannisters.  I can fit 6 cans upright and at least one on its side in there.  Every time I pop the cannister open to retrieve a bottle I can smell gas.  I think I'll go to a more enviro-friendly solution with refillable containers, though.
