Some producers feel that this unbalances their wine, and use spinning cones to reduce the alcohol by 1-2 percentage points. In this case the wine is passed through the column once to distill out the most volatile aroma compounds which are then put to one side while the wine goes through the column a second time at higher temperature to extract ...
The other bulbs can be used to collect the distillates sequentially, when the desired fraction is being collected the bulb is cooled with water or ice to aid condensation. A motor drive is often used to rotate the string of bulbs to reduce bumping , give even heating, and increase the surface area for evaporation.
Flambé is a technique where alcohol, such as brandy, is poured on top of a dish and then ignited to create a visual presentation. [3]A variation of the flambé tradition is employed in Japanese teppanyaki restaurants where a spirit is poured onto the griddle and then lit, providing both a dramatic start to the cooking, and a residue on the griddle which indicates to the chef which parts of ...

Riddling Also known as "Remuage " in French, part of the Méthode Champenoise process whereby bottles of sparkling wine are successively turned and gradually tilted upside down so that sediment settles into the necks of the bottles in preparation for degorgement.
Short-path vacuum distillation apparatus with vertical condenser (cold finger), to minimize the distillation path; 1: Still pot with stirrer bar/anti-bumping granules 2: Cold finger – bent to direct condensate 3: Cooling water out 4: cooling water in 5: Vacuum/gas inlet 6: Distillate flask/distillate.

A rotary evaporator [1] (rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.When referenced in the chemistry research literature, description of the use of this technique and equipment may include the phrase "rotary evaporator", though use is often rather signaled by other language (e.g., "the sample was evaporated ...
An alembic (from Arabic: الإنبيق, romanized: al-inbīq, originating from Ancient Greek: ἄμβιξ, romanized: ambix, 'cup, beaker') [1] [2] [3] is an alchemical still consisting of two vessels connected by a tube, used for distillation of liquids.
