It's now 4 years since I last brewed this recipe, and 31 years since the very first time! Doubling the recipe from July 3, 2021 in order to be able to age a larger quantity since it improves so much with time. Note: The yeast used was Omega OYL-005 Irish Ale Yeast (not in the drop-down menu choices). Cost ~ $125.00 for 13 gallons
