Gose

First, wash all brewing tools (4L stainless steel stockpot, 2L glass fermentation jug, airlock, long-handled stirring spoon, fine-mesh strainer, siphon, 4 x 16oz sealable glass bottles) with hot soapy water, then soak all surfaces that will touch cooled beer in no-rinse food-grade brewing sanitizer for 1 full minute per manufacturer instructions. Poor sanitization is the top cause of spoiled homebrew, so do not skip this step; work on a clean, uncluttered kitchen countertop.

Heat 1.7L (7 cups) of filtered water in the sanitized stockpot to 67°C (153°F) over medium heat, then add all crushed pilsner malt and crushed malted wheat, stirring thoroughly to eliminate any dry grain clumps. Hold the temperature steady at 65-68°C (149-154°F) over the lowest heat setting for 60 minutes, keeping the pot covered and checking temperature with a digital thermometer every 10 minutes to avoid overheating. The mixture will smell like sweet, bready porridge as grain starches convert to fermentable sugar.

After the 60-minute mash, pour the grain mixture through a sanitized fine-mesh strainer into a second clean pot, gently rinsing (sparging) the leftover grain solids with 800ml (3.3 cups) of 77°C (170°F) filtered water to extract remaining sugars. Bring the strained sweet golden liquid (called wort) to a gentle rolling boil over medium-high heat, then add the measured Hallertau hops. Maintain this steady boil for 60 minutes, adjusting heat as needed to prevent sticky boilovers; add the crushed coriander seed and sea salt to the boiling wort during the final 5 minutes of cooking.

Once the 60-minute boil finishes, turn off the heat and move the pot to a clean kitchen sink filled with ice water and ice cubes to create an ice bath. Chill the wort until it reaches 21°C (70°F), which takes approximately 20 minutes, stirring gently every 5 minutes to speed cooling. Once cooled, stir in the measured food-grade lactic acid, tasting with a clean spoon to confirm a bright, tart flavor similar to mild lemonade, not aggressively sour. Strain the cooled wort into your sanitized fermentation jug, leaving any thick hop/grain sediment (called trub) behind in the pot.

Sprinkle the full sachet of dried German ale yeast directly onto the surface of the cooled wort in the fermentation jug, then seal the jug with a sanitized rubber stopper and airlock filled halfway with sanitizer solution. Store the sealed jug in a dark, temperature-stable spot held at a consistent 18-20°C (65-68°F) for 14 full days. You will see small bubbles rising through the airlock within 24-48 hours as active fermentation begins, and bubbling will slow to a near stop once primary fermentation is complete.

After 14 days of primary fermentation, siphon the clear, lightly hazy Gose into 4 sanitized 16oz (473ml) sealable glass bottles, adding 1g (1/4 tsp) of dextrose to each bottle to feed residual yeast and create natural carbonation. Seal bottles tightly with sanitized metal bottle caps, then return them to the same dark, 18-20°C (65-68°F) storage spot for 7 additional days to build carbonation and mellow tart flavors. Before serving, chill bottles in the refrigerator for 24 hours to reach 4°C (40°F) for optimal refreshment.
