Malt Beverages & Seltzers Recipe

Sanitize

Thoroughly sanitize all fermenting equipment, spoons, thermometer and bottles using a no-rinse food-grade sanitizer per manufacturer instructions.

Steep specialty grain

Place the crystal/caramel malt in a mesh grain bag. Heat 1.5 liters of the water to 68–72°C. Add the grain bag and steep for 20 minutes, keeping temperature steady. Remove the bag, allow it to drain into the kettle, and discard the grains.

Dissolve malt extracts and sugars

Bring the steeped water to a gentle boil. Remove from heat and stir in the pale malt extract until fully dissolved to avoid scorching. Return to a light boil, then add the corn/cane sugar and stir until dissolved.

Boil and clarifier (optional)

Boil the wort for 10 minutes. If using Irish moss or other clarifier, add it with 5 minutes left in the boil. This short boil reduces hop bitterness and sanitizes the wort for an extract-style malt beverage.

Cool wort

After the boil, quickly cool the wort to 18–24°C using an ice bath or wort chiller. Top up with cool, filtered water to reach the final volume (~3.8 L / 1 gallon). Aerate the cooled wort by vigorous shaking, stirring, or splashing into the sanitized fermenter.

Pitch yeast

Measure and add yeast nutrient to the cooled wort, then pitch the brewer's yeast according to packaging (rehydrate dry yeast if recommended). Seal with an airlock and place in a dark area at a stable temperature appropriate for the yeast strain (typically 18–22°C for ale yeast).

Primary fermentation

Allow fermentation to proceed for 5–10 days until active bubbling slows and gravity has dropped substantially. Check specific gravity if you have a hydrometer; target final gravity will vary but should indicate fermentation near completion.

Optional fruit or flavor addition

If using fruit puree/juice or botanicals, sanitize additions (or use pasteurized puree). For fruit-forward batches: either add pasteurized fruit directly to secondary fermenter after racking off the primary yeast cake, or add a measured amount (400 g puree) during the last 2–3 days of primary for lighter character. If using citrus zest or extracts, add during secondary to preserve aroma. If using fresh fruit, consider a Campden tablet and potassium sorbate to stabilize before bottling if you want to halt fermentation and maintain sweetness—wait 24 hours after Campden before adding sorbate.

Secondary (optional)

Rack to a sanitized secondary fermenter for clearing if desired and allow 3–5 days for flavors to meld and solids to settle. This step improves clarity for seltzer-style finished products.

Conditioning and priming

If bottling: dissolve priming sugar (50 g) in 60 ml boiling water, cool, and add to sanitized bottling bucket. Transfer beer on top of the priming solution, mix gently to distribute, and bottle in sanitized bottles. If kegging: carbonate in the keg under CO2 to desired volumes (2.5–3 vols for fizzy malt beverages).

Bottle conditioning

Store bottles at 18–22°C for 7–14 days to allow carbonation to develop. Check carbonation by chilling a bottle and opening carefully. Refrigerate finished bottles and consume within a few weeks for best flavor if fruit was used, otherwise store cool and dark.

Preparing fruit puree or juice

If using fresh fruit, wash, chop and puree in a blender. For sanitation, heat the puree to 70°C for 5 minutes (pasteurize), cool rapidly and add to secondary fermenter or at bottling as directed above. If using store-bought pasteurized juice or puree, add directly to the secondary or during bottling stage as preferred.

Using botanicals or zest

For delicate aromatics (mint, basil, zest) add during secondary fermentation or in the final 24–48 hours of primary to preserve aroma. Alternatively steep herbs in 100 ml near-boiling water for 5 minutes, cool, and add the strained infusion to the fermenter. For extracts, add 0.5 tsp at bottling to dial in aroma — start small and adjust in future batches.

Stabilizing sweet fruit batches (optional)

If you want to stop fermentation and retain sweetness from fruit: add Campden tablet (crushed) to the fermenter (per package dosing) and wait 24 hours, then add potassium sorbate (0.5 tsp) before bottling. Note: these do not kill yeast completely; sanitation and proper handling remain important.

Turning malt beverage into seltzer-style drink

To produce a seltzer-style ready-to-drink product, brew the base beverage at lower gravity (reduce malt extract), ferment to dryness, then dilute with chilled seltzer water at serving to taste (typical ratio 3:1 beverage to seltzer). Add fruit puree or natural flavors at serving for bright aroma and low residual sugar.

Serving

Chill bottles or keg to 3–7°C. For a spritz/seltzer-style drink, pour one part chilled malt beverage over ice and top with 1 part chilled seltzer water; garnish with citrus or herbs as desired.

After bottling or kegging, clean all equipment immediately with a non-sanitizing brewery cleaner, then sanitize with a no-rinse sanitizer before next use. Dispose of spent grains and solids responsibly; sanitize work surfaces and store yeast packs per manufacturer instructions.
