I heard they tweaked the recipe just a bit, although I suppose each year is a unique blend of various age statements, wood finishes, and yeast strains. If you consider that this is possibly the most expensive beer in the world, it is pennies compared to the most expensive bottle of wine or spirit. But, it is an investment in an experience of imbibing...which does it for some, not so much for others. At 25abv or so, I consider it similar to sipping a bit of Madeira. Seriously crazy.
Sitting on a bottle of 2008. Nom nom.
