Barack Obama has praised the Hobgoblin beer given to him by David Cameron as "excellent".
The Prime Minister and US President swapped beers at the G20 Summit in Toronto, Canada. Cameron was given a bottle of Chicago's Goose Island 312.
The exchange followed a bet made between the two leaders about the outcome of England versus USA in the World Cup — it was a draw so both paid up.
Obama said he had drunk the Hobgoblin ale, brewed by Marston's owned Wychwood, cold.
"We have just concluded some excellent discussions, including whether the beers from our hometowns that we exchanged are best served warm or cold," he said.
Cameron said he drank the Goose Island 312 while watching the World Cup.
"I enjoyed it so much that when I watched Germany beat Argentina, I actually cheered for Germany," Cameron said.
"That's something that's a big admission for a British person to make, so the beer is obviously very effective."
