Split Top Rotating Column Copper Alembic Stills

With the evolution of time and distilling techniques, this model has been perfected so as to be considered a semi-industrial home distilling unit. The rotating column model is very different from the traditional model in terms of the distilling process and results. It is unique in that it is able to yield a "purer" distillate and is considered a time-saver when you wish to distill various batches.

While the batch and water are mixed together in the traditional Portuguese copper alembic pot, with the rotating column still, the copper pot only functions as a water vapor generator. The batch is not placed in the pot but in the column, thus there is no direct contact with the water.

The column may have one or two copper sieve trays (depending on size) soldered to the column. These perforated copper trays not only separate the batch from the water but also allow the passage of vapors, considered a steam distillation process, ideal not only for alcoholic beverages but also for the distillation of essential oils.

These units are also considered as time-savers as while the water is at boiling point, the distiller can rotate the column to the side, discard the used batch and immediately refill it with a fresh batch, place the column back on the copper pot and proceed with a new distillation. Thus, there is no need to initiate each new distillation with cold water.

If the distiller is not satisfied with the quality or pureness of the distillate from the first distillation, a second rectifying or refining distillation may be carried out with the same unit. For this purpose, the first results are placed in the copper pot, the column is rotated to its side and the alembic head is attached directly on the pot to proceed with the rectifying distillation.

The smaller sizes may be used domestically unlike the larger models which require an adequate distillation area and knowledge by the distiller. Even though these alembic stills are recommended for experienced distillers, this does not mean that those who wish to start with home distilling should feel apprehensive when acquiring one of these models. There are various sizes available up to 300 liters. Models larger than 300 litres are not recommended, as pot is unable to generate the needed vapor to function correctly.

All unions are welded or soldered with lead-free brass or copper depending on location, this is known as a soldered union construction. Thicker copper sheeting is employed in manufacturing these alembics. All connecting parts between the swan neck and the condensing recipient come equipped with rapid brass locking unions to avoid the escape of vapours.

These models may be used for the distillation of alcoholic spirits, essential oils etc, but always bearing in mind that only solid organic materials can be placed in the column. For liquid distillations please refer to our Charentais alembic still.

Basic information on different distilling processes is available on this site and a list of precautions that should be taken into consideration for any model. You may also find a short sequence of pictures and explanatory text of a "Portuguese Experience" - the distillation of Grappa which will also help any newcomer even though this experience does not use the rotating column still.

The separate parts that make up a still have been designed and manufactured to fit together perfectly and seal off all vapours (thus the concave shape of the swan neck head). After years of usage some natural slack may occur between these parts and will need to be sealed off to prevent the escape of vapours. This is achieved with a very simple and rudimentary sealing technique.

Iberian Coppers Lda is proud of our standard line of products; a range of products that can compete with market values, without compromising on quality or safety.

Our standard products are high quality and completely hand made and unique. Many similar models can be found in the markets but we stand out because all our materials are tested and 100% lead free.

The guarantee time on our standard line is 2 years though our products are known to last for decades if taken care of properly. This line is perfect for the distiller who wishes to start experimenting with plants or alcohol spirits, and wants to find a good solution that's great value for money without having to opt between quality / value/ security.

We pride ourselves on improving our products and we have taken this to a whole new level with our premium products. Read below for more information on our Premium line.

Iberian Coppers has always lead the way when it comes to improving our products, coming up with new and better solutions that are built to last for generations to come. Striving to be better is what drove us to certify our products, and now these products are a testament to our improved standard in manufacturing and the safe materials that are used in each unique Premium copper alembic. Our customers can now be assured that what they are purchasing is high quality copper products, tested and manufactured in total safety with 100 % lead free soldering and these products are now CE certified.

We still have our standard competitive priced models which are completely safe and 100% lead free but our Premium line has achieved excellence with details such as:

* CE certification
* thicker copper sheets that require more manual labour and as a result become hand crafted master pieces,
* The alembic set comes complete with brass joints and couplings
* the condenser has a water inlet as well as a water outlet and more serpentine coils
* Brass solders are used instead of copper or phosphorous alloy solders.

These equipments, if treated well, can last an entire lifetime.
