I dropped into one of my local liquor stores last night after noticing they had kegs of beer outside.

CO2 is 2,378 yen for 5kg with a 5,000 yen security deposit.

If it is for 1 or 2 days they will lend a beer serving machine, but not for longer. To buy one outright costs around 300,000 yen.

Shocking price for a beer machine, but on the other hand, I’ve no idea what model it is – it could be a small single tap or it could be an automatic or it could be a big monster with its own chiller.

But the price of CO2 is excellent, and they will deliver it to my house (because I’m local). Given that a tank will last a year, you can’t really quibble at 2,378 yen, can you? That’s around $20-25.
