The Different Types of Alcohol Stills in Australia?

It is both an art and a science to distill alcohol, which is why the type of stills used is critical to the process since it determines the efficiency, flavor, and quality of the final product. In Australia, the focus towards craft spirits, home distilling, and artisan production has developed interest in the market and thus a wide variety of alcohol stills is now available. Whether you are a hobbyist experimenting with small batches or a commercial distillery, there's a still to suit your needs. This article explores the different types of alcohol stills commonly used in Australia, their features, and their applications.

1.Pot Stills

Known for their simplicity and their ability to produce flavorful spirits, pot stills remain an industry favorite to this day. They are popular with craft distillers and home enthusiasts due to their ease of use.

Features:

1.Design: Consists of a pot (or boiler), a condenser, and a collection vessel.

2.Material: Usually copper for flavor enhancement, or stainless steel for greater durability.

3.Operation: Works on a batch process, meaning, works once for a single batch at a time.

Uses:

Pot stills perfectly serve the purpose of distilling brandy, rum, and whisky because they possess exquisite and intriguing flavors. They are used by small pot still distillers who value quality first over quantity.

Benefits:

●Produces spirits with strong flavor.

●Easy to use and service.

●Ideal for small and medium size production.

Drawbacks:

●Compared to column stills, they have lower purity of alcohol.

●They are not effective in mass production.

2.Column Stills (Fractionating Stills)

Commercial distilleries use column stills, or fractionating stills, which employ a continuous distillation process, as the name suggests.

Specifications:

1.Design: Contains multiple plates or trays to distill and remove impurities from alcohol.

2.Material: Should be Copper or Stainless Steel.

3.Operation: Simple, enables distillation to occur without disruption, and achieves maximum efficiency.

Uses:

Column stills are used for neutral spirits, vodka, and gin and even for industrials spirits with high concentration.

Benefits:

●Great throughput and high production rate.

●Makes spirits with high concentration of alcohol and purity.

●Ideal for large scale production.

Drawbacks:

●Expensive to construct in comparison to pot stills.

●Difficult to work with in regard to design complexity.

3.Reflux Still

Popular with small-scale producers and home distillers, reflux stills are a specific form of column still which aims to produce alcohol with high purity.

Characteristics:

1.Design: The reflux condenser enhances the alcohol seize by vaporization which makes it possible to retain sufficient alcohol for maximum purity.

2.Material: Usually constructed of stainless steel or copper alloys.

3.Operation: Achieves higher purity compared to pot stills, however, it does operate in a single batch mode.

Applications:

Reflux stills are purposed to achieve extraction of neutral spirits like Vodka or phenols from their oils.

Advantages:

●Achieves high purity alcohol up to 95% ABV.

●Compact and economical.

●Ideal for small to medium scale production.

Disadvantages:

●Lacks the depth of taste of pot stills.

●Takes a certain degree of proficiency to use correctly.

4.Hybrid Stills

Hybrid stills are customizable as they cater the functionalities of pot and column stills. Hence, they are very handy for distillers whose desire is to get branded beverage with distinct flavor or neutral spirit.

Features:

1.Design: Capable of working as both a pot still and reflux still.

2.Material: Copper or stainless steel.

3.Operation: Allows versatility in the type of distillation process done.

Applications:

Hybrid stills are useful in production of all types of spirits; whiskey, rum, vodka, even gin.

Advantages:

●Advanced technology in the spirit distillation industry.

●Ideal for small or medium scale production.

●Captures the advantages from pot and column stills.

Disadvantages:

●More expensive than single purpose stills.

●Needs more room and equipment.

5.Flute Stills

Flute stills are known as a specific type of column still adaptive” to allow the efficiency of distillation to be maximized and done uninterrupted.

Features:

1.Design: An outline of a flute with multiple plates.

2.Material: Uses copper which conducts heat very well.

3.Operation: Permits uninterrupted high volume distillation

Applications:

Flute stills are best optimised with rum and whisky production.

Advantages:

●Always yields positive results.

●Balanced flavor spirits are produced.

●Medium scale to large scale production can be done.

Disadvantages:

●Operating the valve is costly.

●Space and setup costs are high.

6.Alembic Stills

Alembic stills are often used for low volume distilling operations and are often referred to as traditional dish copper stills as they are onion shaped.

Features:

1.Design: A pot with a swan neck and heats the liquid in the condenser.

2.Material: The use of copper allows the pot to retain heat as well add flavor.

3.Operation: The batch distillation method.

Applications:

Alembic stills are most acclaimed for brandy, whisky, and essence oil distillation.

Advantages:

●Yields high flavoring spirits.

●Nice to look at and decorations

●Best used or fine production.

Disadvantages:

●Fewer whiskeys produced than with column stills.

●Cannot sustain large-scale production.

7.Continuous Stills

As for continuous stills, they are built for effective and commercial use as they tackle the issue of huge volumes on uninterrupted distillation.

Features:

1.Design: Designs includes continuous input of raw materials as well as output of distilled products.

2.Material: Made of stainless steel or copper.

3.Operation: High throughput process with minimal downtime.

Applications:

Continuous stills are suitable for use in the industrial alcohol and large-scale spirit manufacturing industries.

Advantages:

●Highly cost-efficient and economical for large-scale production.

●Less manual intervention needed.

Disadvantages:

●High and complex setup costs.

●Artisanal and small-scale production are not possible.

8.Mini Stills (Home Distilling Kits)

Mini stills are created to meet the needs of home distilling hobbyists. Easy and affordable to set up, they in no way compromise on performance.

Features:

1.Design: Portable and compact.

2.Material: Made of stainless steel or copper.

3.Operation: Easier batch distillation.

Applications:

Mini stills are perfect for home distilling essential oils, spirits, or herbal extractions.

Advantages:

●Affordable and simple to operate.

●Useful for beginners and for distilling small quantities.

Disadvantages:

●Inefficient and small scale.

●Large scale production of courses is difficult.

9.Vacuum Stills

The main feature of vacuum stills is the ability to perform distillation under lowered pressures. This allows delicate flavours and aromas to be distilled without damaging them through overcooking.

Features:

1.Design: Contains a vacuum pump to reduce pressure.

2.Material: Constructed from stainless steel or glass.

3.Operation: Lower the temperature when distilling to retain flavour integrity.

Essential oils, herbal extracts, and high-quality spirits are best produced using vacuum stills.
