From Ingredient to Spirit
Craft distillation is, at its core, a series of transformations. A raw agricultural material (grain, fruit, sugarcane, coconut flower nectar) is converted into alcohol through fermentation, then concentrated and purified through distillation. The skill of the distiller lies in controlling every stage so that the final spirit expresses the best qualities of the original ingredient.
Here is what that process looks like at each stage.
Stage One: The Raw Material
Every spirit begins with a fermentable sugar source. The choice of raw material determines the fundamental character of the spirit before any process decisions are made.
Vodka and gin typically start with grain (wheat, rye, corn) or, in the case of Sanpatong Distillery, 100% pure cassava, a naturally gluten-free, non-GMO root crop. Rum starts with either molasses (a byproduct of sugar refining) or fresh sugarcane juice; the latter produces Rhum Agricole, a fundamentally different spirit. Brandy starts with fruit: grapes for grape brandy, apples for Calvados, and in Sanpatong's case, coconut flower nectar, mango, longan, lychee and other tropical fruits for its Eau de Vie collection and Fusion Gin base.
The quality of the raw material is the single most important factor in the quality of the final spirit. A craft distiller selects ingredients for their flavour contribution, not their price. An industrial producer selects for cost.
Stage Two: Fermentation
Fermentation is the process by which yeast converts the sugars in the raw material into alcohol. This stage is often underappreciated, but it is where much of the spirit's flavour profile is established.
The distiller's decisions at this stage include: which yeast strain to use (different strains produce different flavour compounds), the temperature at which fermentation takes place (lower temperatures generally produce cleaner, more refined fermentation), and how long to allow fermentation to continue.
Craft distillers typically favour slower, cooler fermentation because it produces fewer of the harsh congeners that create off-flavours. Sanpatong uses yeast cultures developed specifically for each base ingredient, with fully temperature-controlled fermentation, to ensure that the natural character of the raw material is preserved.
Industrial producers ferment as quickly as possible to maximise volume. The resulting off-flavours are then removed through aggressive filtration or masked with additives.
Stage Three: Distillation
Distillation is the process of heating the fermented liquid (called the 'wash' or 'wine') to separate the alcohol from the water and other compounds. Because alcohol evaporates at a lower temperature than water, heating the wash produces a vapour that is richer in alcohol. This vapour is then condensed back into liquid.
There are two primary distillation methods:
Column stills (continuous stills) produce spirit continuously and at high volume. They are efficient and consistent, but they tend to strip out much of the character of the raw material, producing a relatively neutral spirit. Column stills are standard in industrial production.
Pot stills (batch stills) process one batch at a time. They are slower and less efficient, but they give the distiller far greater control over what enters the final spirit. Because pot distillation retains more of the raw material's character, it produces spirits with more complexity and depth.
Copper is the preferred material for pot stills because it reacts with sulphur compounds in the vapour, removing undesirable flavours. This is a natural purification process that happens during distillation itself, not through chemical treatment afterwards.
Sanpatong uses multi-stage alembic copper pot stills with ambient-cooled copper reflux pipes. The reflux pipe allows vapour to rise, partially condense and fall back through the still, effectively providing additional refinement within a single distillation run. This achieves exceptional purity while preserving the character of the raw material.
The Heart Cut
During distillation, the spirit comes off the still in three fractions. The 'heads' (or foreshots) contain volatile compounds like methanol and acetone. The 'tails' (or feints) contain heavier compounds that contribute harshness and off-flavours. The 'heart' is the middle fraction, where the purest and most flavourful spirit is found.
A craft distiller makes the cut decisions manually, choosing precisely when to start and stop collecting the heart. These decisions are based on experience, sensory evaluation and knowledge of the specific raw material. The tighter the cut, the purer the heart, but the lower the yield.
Industrial producers make wider cuts to maximise volume, then deal with the resulting impurities through filtration and additives. Craft distillers take less spirit from each run but produce a cleaner, more characterful product.
Stage Four: Resting
After distillation, many craft spirits benefit from a resting period. This is not the same as ageing in barrels (though some spirits, like whisky and aged rum, do that as well). Resting allows the spirit to settle, for harsh volatile compounds to dissipate and for the flavour to integrate.
Sanpatong rests all spirits for a minimum of 120 days in bespoke stainless steel resting tanks before bottling. This is a deliberate quality step that most industrial producers skip entirely, preferring to move product from still to bottle as quickly as possible.
Stage Five: Bottling
In an additive-free operation, the only addition at bottling is water to bring the spirit to its final ABV. No colourings, sweeteners, flavourings or chemical smoothing agents are introduced.
For craft distillers committed to transparency, bottling is also the point at which batch numbers, vintage designations and other traceability information are applied. Sanpatong's Distiller's Reserve Eau de Vie collection, for example, is individually numbered and hand-signed, with each release designated by its vintage year (Millesime).
What 'Craft' Should Mean
The word 'craft' is not legally defined in most spirits markets. This means it is used freely by producers whose methods range from genuinely artisanal to barely distinguishable from industrial production.
At Sanpatong Distillery, craft means something specific: an integrated farm-to-bottle process with chemical-free ingredients, multi-stage copper pot still distillation, no activated carbon purification, no post-distillation additives and a minimum of 120 days resting before bottling. Every spirit is produced on site in Chiang Mai, from identified and traceable raw materials.
See It for Yourself
Understanding how spirits are made is valuable. Experiencing it first hand is better.
Sanpatong Distillery offers a Signature Distillery Tour and Tasting, where visitors can see the full production process from raw ingredient to finished spirit, and taste the results across the portfolio. For those wanting to go deeper, the Signature Cocktail Masterclass provides hands-on experience with Sanpatong spirits in a guided cocktail-making session.
Both experiences are available by arrangement. Contact tours@sanpatong.com to book.
Sanpatong Distillery is based in San Pa Tong, Chiang Mai, Thailand. All spirits are handcrafted through an integrated farm-to-bottle process.
