An Australian standard drink is 10 g alcohol.
An American standard drink is 14 g alcohol.
In Japan it is 19.75 grams (25 ml) alcohol.
Tod suspects that Japan's drinking policies were written at a nomikai (aka a booze-up, kegger, or boy's night out).
So a 750 ml bottle of wine is 5 drinks in the US, 7.5 in Australia, and about 4 in Japan. A 500 ml beer is 2 drinks in Australia. In Japan, 500 ml of beer is 1 drink. 12 oz (350 ml) of beer is 1 drink in the US.
How much alcohol makes you too drunk to do whatever? After 6 American drinks/8.5 Australian drinks/4.3 Japanese drinks (taken in as homemade frozen margaritas) in 3 hours, I am finding it a little more difficult than usual to type, but conversation is flowing nicely and I can still walk straight.
As Jimmy Liggins sang, "I ain't drunk, I'm just drinkin'!" but I'm nowhere near Dead Kennedys levels here.
MORNING AFTER UPDATE: I wronged the math in our frozen margaritas. Tod thinks our jigger is 45 ml, but it is actually only 30ml. So I really had 4.3 American drinks/6 Australian drinks/3 Japanese drinks. Not too drunk after all.
And in case you wonder what our favorite margarita recipe is, it comes from Drink Boy: http://www.drinkboy.com/Cocktails/recipes/Margarita.html To make it frozen, we blend it with ice.
After the Dead Kennedies comment I was expecting the morning after update to be about something else.
I'm a total lightweight then. If I have even a sip over two glasses of wine I get the spins.
