Copper Bain-Marie Alembic Still: Gentle Distillation for Thick Mashes Without Scorching

If you plan to work with dense fruit raw materials, grape pomace, or thick grain mashes, a standard distiller might not cut it. For these ambitious distilling projects, we recommend buying a Portuguese copper Bain-Marie alembic still. This professional-grade equipment guarantees gentle and even heating, completely eliminating the risk of ruining your batch with a burnt aftertaste.

Like all the distilling equipment in our shop, our water bath models are handcrafted by traditional, generational artisans in Portugal using highly purified, food-grade copper.

How Does the Bain-Marie (Water Bath) Distillation System Work?

The secret behind this premium copper still lies in the unique design of the boiler—it features a double-wall construction, often called a water jacket.

1. Water is poured into the jacket between the inner and outer walls.

2. The heat source (gas or electric stove) heats only the outer wall and the water inside the jacket.

3. The hot water gently and evenly transfers heat to the inner pot holding your mash.

Thanks to this physical process, the heating temperature of the mash never exceeds 100°C (212°F), which is the boiling point of water in the jacket. Direct contact between the thick mash and a scorching-hot bottom is completely prevented.

Key Advantages of the Water Jacket Alembic Still

Investing in a water-jacketed alembic still means securing the flawless quality of your spirits and your own peace of mind. Here are its key benefits:

• 100% Scorching Protection: Confidently distill unfiltered mashes, thick fruit purees, and dense grain washes. Nothing will stick to the bottom, ensuring your precious distillate never gets a bitter, burnt smell.

• Ideal for Pomace Distillation: Easily distill grape pomace with skins and seeds to extract maximum aroma and flavor.

• Precise Distillation Control: Uniform heating via the water layer makes the distillation process incredibly stable. This allows the distiller to make razor-sharp cuts between "heads" and "tails."

• Extends Copper Lifespan: The absence of burnt particles on the bottom makes cleaning the copper pot significantly easier and extends the overall lifespan of your equipment.

Essential Equipment for Crafting Premium Spirits

A copper water bath distiller is the number one choice for traditional spirits with a rich organoleptic profile, where distilling with solids is required:

• Grape Pomace Spirits: Classic Italian Grappa, Georgian Chacha, and French Marc.

• Fruit Distillates from Unfiltered Puree: Authentic Balkan Slivovitz (plum brandy), apricot schnapps, or thick apple and pear mashes.

• Grain Distillates ("Red Scheme"): Bourbon, Scotch whisky, and traditional rye Polugar (where the mash is distilled together with the spent grains).

What’s Included: Standard Configuration

The standard assembly of an authentic Portuguese Bain-Marie alembic includes:

1. Double-Walled Copper Pot Still: Equipped with inlets for filling and monitoring the water level in the jacket, as well as a safety valve to release excess steam pressure.

2. Traditional Copper Onion Dome (Alembic Helmet): Functions as an air deflegmator, naturally purifying vapors from sulfur compounds.

3. Swan Neck Condenser Pipe.

4. Condenser Cooling Tank with Coil: For fast, efficient condensation of alcohol vapors.
