I have no alcohol - Help!

[StSaint]

Okay so i'm in Black Plague, at the point where you're outside and must set light to the barrels to blow a hole in the snow, and i've put the cloth into the barrel, and it won't light. Now I know the walkthroughs i've seen all say I need to use the Alcohol on the cloth, but one issue: I HAVE NO ALCOHOL. I know there was alcohol at the start of the game, when I used it on the syringe, but after that it disappeared, and as far as i'm aware that's the only one you get. Can you help me? Please hurry, i'm really enjoying this game and i'd hate something like this to break my stride with it.
