Handling the calamansi with clean hands and utensils is crucial to prevent contamination and ensure the safety of the fermented drink.

Creating the Base Calamansi Juice

Creating a flavourful base is essential for quality fermented calamansi liquor. One should begin by washing the calamansi thoroughly under running water, drying them afterwards to remove any lingering dirt or impurities. The aim is to extract the maximum amount of juice while discarding the seeds, as they can impart a bitter taste.

  1. Wash: Rinse the calamansi under cold, running water.

  2. Dry: Pat dry with a clean cloth or paper towel.

  3. Juice: Cut the calamansi in half and squeeze to extract the juice, straining to remove seeds and excess pulp.

  4. Measure: Collect 1 1/2 cups of calamansi juice for the recipe.

After juicing, sugar is typically added to the calamansi juice. The sugar acts as a food source for the bacteria that will drive the fermentation process.

  • Sugar: Incorporate a precise ratio to the juice – often, recipes call for about a cup of sugar to 800ml of water, but this can vary based on personal taste preferences.

Sanitation and Safety

Cleanliness is paramount in fermentation to ensure only the desired bacteria are present in the process. All equipment that will come into contact with the ingredients should be sterilized beforehand to eliminate any harmful microbes.

  • Containers: Use glass or food-grade plastic that has been thoroughly cleaned and sanitized.

  • Utensils: Ensure all spoons, measuring cups, and juicers are disinfected.

Once the calamansi juice and sugar base are ready, they must be transferred to the sanitized container for the fermentation to begin. Proper sanitation avoids the growth of unwanted microorganisms that could spoil the calamansi liquor.

The fermentation process for creating Calamansi liquor involves careful preparation of ingredients, maintaining a clean environment, and being patient as natural fermentation takes place. This guide will walk you through each step to ensure your citrus drink develops the desired taste and aroma.

Ingredients and Equipment

Ingredients:

  • Calamansi juice: 1 1/2 cups

  • Sugar: 1 cup (simple syrup or honey as alternatives)

  • Water: 800ml, preferably filtered

  • Yeast: wine yeast or a natural starter like ginger bug

Equipment:

  • Fermentation vessel: glass jar or food-grade plastic container

  • Airlock or cheesecloth and rubber band

  • Measuring utensils

  • Mixing spoon

  • Fine mesh strainer

  • Bottles for storage

Mixing and Primary Fermentation

Combine the calamansi juice, sugar, and water in your fermentation vessel. Stir the mixture until the sugar completely dissolves. Add your chosen yeast or starter, such as a small amount of ginger bug, to introduce the necessary microbes for fermentation.

Cover the container with an airlock or cheesecloth secured with a rubber band. This allows carbon dioxide to escape while keeping contaminants out. Store the vessel in a cool, dark place with a consistent temperature between 65-70 degrees Fahrenheit. The primary fermentation phase usually lasts about one week, though it can be shorter or longer depending on environmental factors and the potency of your yeast or starter.

Secondary Fermentation and Flavoring

After primary fermentation, strain the mixture to remove any pulp or sediment. For secondary fermentation, transfer the liquid to a clean container, leaving some headspace to allow for expansion. If extra flavor is desired, this is the stage to add complementary flavors like lemon, lime, or ginger.

Re-secure the cheesecloth or airlock and allow the calamansi liquor to ferment further. This could take additional weeks or months depending on the desired strength and flavor complexity. During this time, natural carbonation can develop, enhancing the texture of the liquor. The longer it ferments, the more nuanced the taste will become. Once the desired flavor profile is reached, transfer the finished liquor into bottles, seal them and store in a cool, dark place.

Finishing and Bottling

After the initial fermentation process, the next crucial steps are monitoring the brew's maturation and the bottling procedure, which will ensure the Calamansi liquor achieves the desired taste profile and clarity.

Monitoring Fermentation and Maturation

Successful fermentation relies on careful observation. One must monitor:

  • Acidity: Essential for taste balance and microbial stability.

  • Alcohol Content: Indicates the completion of fermentation when it stabilizes.

  • Fermentation Activity: Observing the cessation of bubble formation, which may be reminiscent of soda water effervescence, implies fermentation is nearing its end.

The brewer should taste the Calamansi liquor periodically to ensure it is developing the desired characteristics. Once the bubbling activity decreases significantly, this typically suggests that the sugars have been consumed and alcohol production is stable.

Clarifying and Bottling

Once the fermentation has subsided:

  1. Clarification:

    • Transfer the liquor into a clean vessel, leaving sediment behind.

    • Use cheesecloth to filter out any remaining particles, if necessary.

  2. Preparation for Bottling:

    • Ensure bottles are sanitized to prevent any contamination.

    • If creating a Calamansi hard lemonade or cocktail, consider the desired carbonation level which can be adjusted by adding a measured amount of sugar before bottling to induce secondary fermentation.

  3. Bottling:

    • Fill each bottle, leaving an appropriate headspace.

    • Seal with a tight-fitting cap.

After bottling, store the liquor in a cool, dark place for maturation. The duration of this period can vary depending on desired taste and alcohol content, much like the aging process of spirits or kombucha. The final product should offer a harmonious blend of Calamansi's unique citrus notes with the complexity that fermentation imparts.
