Released after five years on the yeast, this is still a young, tartly aggressive bubbly. It is in fact by far the most acidic of Iron Horse’s current stable of superb bubblies. But it’s enormously rich, offering a wealth of subtle lime, peach, strawberry, toast and sourdough bread flavors that impress with both depth and length, as well as sheer class. Wonderful now, and should age effortlessly for six to eight years.——S.H.(12/31/2007)—— 93
