Handcrafted Rum Recipe

1. Sanitation

Thoroughly sanitize fermentation vessel, spoons, airlock, and any tools with a no-rinse sanitizer. Good sanitation prevents off-flavors and bacterial spoilage.

2. Combine cane juice (or diluted molasses) and water in the sanitized fermentation vessel. If using molasses, dissolve 500 g granulated sugar into the combined liquids to reach a starting specific gravity around 1.070–1.090 (approx. 17–22 °Bx). Stir until completely dissolved and lukewarm (20–25°C / 68–77°F).

3. Measure and adjust acidity: add 1 tsp acid blend (or citric acid) and stir. This brings the pH to a favorable range for yeast (around 4.5–5.5).

4. Add yeast nutrient (2 tsp). This supports healthy fermentation when fermenting sugar-rich washes like molasses or pure cane juice.

5. Rehydrate the distiller's yeast according to packet instructions if required, then pitch into the wash. Seal the vessel with an airlock and place in a stable temperature environment of 20–28°C (68–82°F).

6. Ferment for 5–10 days until bubbling subsides and the specific gravity reaches 1.000–0.995 (or when active fermentation has fully stopped). For higher alcohol tolerance and cleaner profile, allow a slower, cooler ferment (5–7 days).

7. After fermentation is complete, cold crash the wash (if possible) to 4–10°C for 24–48 hours to help solids settle. Rack or siphon the clear wash off the lees into a sanitized container for distillation. Typical fermented volume here should be about 4 liters.

8. Set up a small pot still or column still according to manufacturer instructions. Ensure all joints are sealed and condenser is working. Use proper ventilation and follow local law — distillation of alcohol may be illegal without permits in your area.

9. Charge the still with the fermented wash (about 4 liters). Heat slowly and monitor temperature and output closely. Aim for a steady, gentle reflux that produces a clear, fragrant distillate.

10. Foreshots (heads) - safety cut

Discard the first fractions (foreshots) that come off: typically the first 20–50 ml from this batch size. These volatile compounds (including methanol) are unsafe to consume.

11. Heads

Collect heads separately after foreshots. Heads contain lighter, solvent-like aromas. For a cleaner rum, stop collecting heads when the temperature and aroma start to shift from sharp solvents to fruitier or cleaner alcohol — roughly until you have collected 5–10% of the expected final potable spirit volume.

12. Hearts

Begin collecting the hearts (the desirable drinking fraction) once the aroma is sweet, clean, with estery or molasses/cane notes. Collect hearts until you notice a decline in aroma quality or the proof drops to a predetermined cutoff (for small runs, many distillers cut hearts based on aroma and taste, or when distillate falls below ~40–50% ABV depending on method). Combine heart fractions; this is your clear raw rum.

13. Tails

As heavier, oily, or wet-wood aromas appear and the proof drops, stop collecting hearts and collect tails separately. Tails contain fusel oils and heavier congeners. You can save tails to redistill with a future run or discard. Optionally, polish the tails fraction by passing through activated charcoal (2 tbs) in a mesh bag to remove some off-notes.

14. Measure the volume and alcohol strength of the collected hearts. Typical yield from this wash will be roughly 700–900 ml of high-proof distillate depending on starting gravity and efficiency.

15. Prepare your aging vessel: if using oak chips, toast them in a dry pan for a few minutes until aromatic but not burnt, then allow to cool. Place 2 tbs of medium-toast oak chips into a small sanitized jar or into a small toasted oak barrel.

16. Pour the clear distillate (about 750 ml) into the jar or barrel. Add the split half vanilla bean and optional 10 g dried fruit/spices if making a spiced expression. Seal the jar or bung the barrel and store at room temperature out of direct sunlight.

17. Age for a minimum of 2 weeks to start extracting color and oak-derived flavors; for deeper color and complexity let it age 3–12 months, tasting periodically. For quick small-batch results, taste every 5–7 days in the first month and then monthly. When using oak chips, you will reach desired flavor faster than with a full stave barrel.

18. When the desired oak and flavor balance is reached, remove oak chips and any macerated solids. If you used optional spices, decide if you want to remove them after a short maceration (for subtle spice) or leave for longer (for stronger spice).

19. Proof down to bottling strength (typical rum 40–45% ABV) by adding chilled filtered water. Example: if distillate measures ~65% ABV at 750 ml and you want 40% ABV final, use the formula Vw = Vd*(Ad - Af)/Af where Vw is water volume, Vd is distillate volume, Ad is distillate ABV, Af is final ABV. For convenience, add approximately 125 ml water and check with a hydrometer/alcoholmeter, then adjust to taste.

20. Optional: add 1 tsp caramelized sugar dissolved in a little warm water to adjust color and round the mouthfeel. Mix thoroughly and let rest 24–72 hours for flavors to marry.

21. Filter the rum through fine mesh or coffee filter if needed to remove particulates, then bottle in sanitized glass bottles. Label with batch date and ABV.
