Since most brewing yeasts couldn't survive and make beer at that level, the brewers had to get creative with freezing to make brews at such a level.
There are some beers on the markets should you want to try any of them it would be best to hire a cab to bring you home or at least a designated driver, so if you want to try one of these beers OK, just don't drive its not worth it !!!!!!!!
