Bentonite fining does have some disadvantages. Firstly, some aroma and flavour molecules are not immune from the attractive forces of the bentonite plates.
Bentonite is probably the choice of most winemakers, as it is easy to prepare and easy to use. It is prepared as a 5% slurry by mixing 50 grams of bentonite powder into one litre of hot water.

A Wyoming clay used to clear wines. It swells up in water then used as finings it absorbs proteins (haze particles) in the wine, dragging them to the bottom as a sediment.
Italian word meaning ‘White’.
Special "clay" which acts as a "fining" agent for the wine, in order to avoid the formation of a sediment in the bottle.

Bentonite - A type of clay used in wine clarification.
The Berthomeau Report - Commissioned by French Ministry of Agriculture to better position the wine industry for the future.
Bentonite - Fine clay containing a volcanic ash derivative called montromillonite, a hydrated silicate of magnesium that activates a precipitation in wine when used as a fining agent.
Bentonite: A natural clay which is used in fining (clearing) wines.
Berry: Common name given to an individual grape.
Berry Set: The fixing of tiny, newly pollenated berries to the stem.
Bentonite Clay often used in fining wine, particularly white. The bentonite removes protein, helping to ensure a perfectly clear wine in bottle.
Bentonite: A purified natural clay that is used in fining white wines for the purpose of correcting heat instability.

A brownish-gray clay which is dissolved in warm water then stirred into the fermenting wine.
BENTONITE: See Fining. Clay, found around Fort Benton in the USA that can be used as a fining agent. Because it is negatively charged, it attracts positively charged particles, causing large clumps to form & settle out.

Fine clay containing ash which activates precipitation when used as a fining agent in wine.
Bentonite has largely replaced all other fining agents. Such fining agents as gelatin, casein, isinglass, albumin, egg white, nylon, and PVPP (polyvinyl pyrrolidone) may be used for special purposes, including removal of excess tannin or colour.
A powdery clay found in Wyoming and Germany that is used as a fining agent to clarify wine.

Fining: Removing suspended solids from a cloudy wine by temperature adjustment, blending with an already cleared wine of the same variety, filtering, or adding a fining material such as egg white, milk, gelatin, casein, or bentonite.
A technique for clarifying wine (i.e. removing small sediment particles) using agents such as bentonite (powdered clay), isinglass (fish bladder), casein (milk protein), gelatin or egg whites.
A traditional technique for clarifying wines by adding material such as clay (bentonite), egg whites, gelatin or isinglass to wine containers. The clarifying agent attracts suspended particles and slowly sinks to the bottom, after which it is removed.
A coagulant such as bentonite, isinglass or egg white is added to the wine to collect proteins and other undesirable compounds.
It's usually accomplished by fining with an agent such as bentonite just prior to bottling. Fining collects the minute particles that cause cloudiness and settles them to the bottom of the storage vessel.
The most frequently used fining agents are activated carbon, activated charcoal, bentonite, casein, egg whites, gelatin, isinglass, nylon, and polyvinyl poly-pyrrolidone (PVPP).
Clarifying wines by adding egg whites or bentonite (clay) to wine; the eggs collect particles and sediment and slowly sink to the bottom. The wine is then racked leaving the solids behind.
Most, like gelatin, and egg whites, are proteins, while another is Bentonite a form of clay. The general concept is to add a substance to the wine that the cloudy particles will stick to, and fall to the bottom.
I have a question I am doing my first batch of wine red grapes. I am just wondering if I add my bentonite in the begining of my first racking, can I add it again in my second racking three weeks later or no? Read More ...
Europeans used to use ox blood. Today common fining agents are egg whites, gelatin, bentonite or diatomaceous earth. The fining agent combines with particles in the wine, causing them to settle to the bottom of the tank.
fining, clarification technique involving adding a fining agent (such as egg whites or bentonite) which attracts solids to fall to the bottom of a container.
This is usually done by adding egg whites or another fining agent (like bentonite) that using ionic bonding to attract the solids and drop them out of the wine. This technique removes the protein haze that sometimes forms.
Fining - this is done by adding a fining agent to the wine which causes the lees to fall to the bottom from where they can be racked off. The main fining agent for white wine is a clay called Bentonite.

A method of clarification of wine using a chemical agent that is added to the wine to which certain unwanted dissolved substances and microscopic particles will adhere and can then be removed. Agents used range from inorganic material like bentonite, ...
Fine: to reduce the solids content of wine after fermentation. In traditional operations, egg whites, milk solids or blood is used, more often, a fine clay called "bentonite" or the like is used.
The process of removing solid particles suspended in wine using any number of techniques including adding fining materials to the wine such as egg whites, gelatin, casein (milk proteins), or bentonite (clay).
Fining agents include egg white, milk, blood, gelatin, carbon, casein (the principal protein constituent of milk and cheese) and isinglass (an extract of sturgeon bladders). Heat stabilization is a fining process that uses bentonite (a clay of ...
Fining can lower high levels of tannin, remove haze and reduce color. Heat stabilization is another goal accomplished by fining, using bentonite (a clay of hydrated magnesium silicates) to remove protein, which may cloud a wine.
