Notes

Jonathan Eckles and Allison Eckles of Savannah, GA, a member of the Savannah Brewers League homebrew club, won a gold medal in Category 28: Spiced Beer in the 2023 National Homebrew Competition Final Round in San Diego. The Eckles’s Sweet Stout earned gold out of 132 entries.

Use carbon-filtered Savannah municipal water from Floridan aquifer. Mash at 152°F (67°C) for approximately 60 min. (I sparged too cold, at 125°F (52°C) and did not get good extraction. Suggest warmer sparge.) Ferment at 65°F (18°C). Grind cocoa nibs in coffee grinder and sterilize with ethanol prior to addition. Soak vanilla beans overnight in ethanol to enhance flavor extraction. If is not sweet enough after secondary, add another 8 oz. (227 g) lactose. (Note that ethanol can be any spirit of your choice.)
