The liver is the major processor of alcohol in the human body.

Your liver cannot store alcohol. It metabolises about 90 per cent of the alcohol you drink, (the rest is excreted through your urine and sweat). Your liver can process about 10g - or a small drink an hour, any remaining alcohol circulates in your blood until it can be broken down - this is how ‘blood alcohol concentration’ is assessed for drink drive limits, for example.

I agree with hippy.

The comment "It takes 8 hours to digest something" is misleading.
