What do elves drink?

Tonight's beverage is a glass of oatmeal stout. I'm assuming it's a health drink because oats are healthy, it's virtually drinking porridge. Plus on the side it states, "with hints of chocolate, liquorice and dandelion and burdock."

But the main thing is it has a picture of a Christmas elf on it and no elf would lend his image to an unhealthy beverage.

But it got me thinking. Santa gets sherry in every British house and milk in the USA. But no one ever thinks of the elves. Even the reindeers get carrots left out but no one leaves anything for the hard working elves.

Santa's fat, elves are not. Says everything doesn't it?
