I had a unique opportunity to try 2018-03 alongside the 04 batch. I ordered a 2 oz pour, and the bar just finished the last ounce of 03 and poured a measure of 04 in a separate glencairn. It might be purely the power of suggestion but I feel like I can taste the additional months in the barrel. In spite of the 04 bottle being newly cracked, it is mellower and sweeter, rounded and richer than the younger, peppery 03. N: Maple syrup and buttered toast, licorice, peanut butter, vanilla, roasted nuts. P: Pecan pie, ice cream, anise, raisins, Graham crackers. F: long, sweet, tannic barrel notes, molasses.
