I heard about this beer made at the westvleteren abbey while in Belgium and drove a couple hours to get to the abbey...it was closed. Back in England I phoned every Monday (?) to try and reserve a case, I called hundreds of times, every Monday for months and couldn't get through. Finally I drove back to the abbey, through France so I could eat and drink a little on the way and they were open.
The abbey has a restaurant where they serve home made Hanm, home made cheese, on homemade bread with their beer. One of the finest meals I've ever had, simple but perfection in every item. At 12% I could only have one beer and still be able to drive but I could have had more....many more. When you go to the restaurant you can buy a six pack of beer, my wife and I each got one of course and treated each bottle like treasure.
