Bentonite fining does have some disadvantages. Firstly, some aroma and flavour molecules are not immune from the attractive forces of the bentonite plates. Therefore, its use to fine out unwanted proteins can also produce an inadvertent loss of varietal character in the wine.
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.

Fine clay containing ash which activates precipitation when used as a fining agent in wine.
~ 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.
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 ~.
A wine-making shop will also have finings, sparkolloid and ~, which will attract the particulate matter that makes mead cloudy. This really speeds up the clearing process which can take months on it's own.
A traditional technique for clarifying wines by adding material such as clay (~), 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 ~, 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 ~ just prior to bottling. Fining collects the minute particles that cause cloudiness and settles them to the bottom of the storage vessel. The wine is then racked to separate the clear wine from the sediment.
The most frequently used fining agents are activated carbon, activated charcoal, ~, casein, egg whites, gelatin, isinglass, nylon, and polyvinyl poly-pyrrolidone (PVPP).
Fining: A technique for clarifying wine using agents such as ~ (powdered clay), gelatin or egg whites, which combine with sediment particles and cause them to settle to the bottom, where they can be easily removed.
fining, clarification technique involving adding a fining agent (such as egg whites or ~) which attracts solids to fall to the bottom of a container.

Fining—A technique for clarifying wine. Europeans used to use ox blood. Today common fining agents are egg whites, gelatin, ~ or diatomaceous earth. The fining agent combines with particles in the wine, causing them to settle to the bottom of the tank.
The winemaking process ensures the wine is thoroughly clarified (even if it may mean stripping the wine of some of its flavour) before it is bottled, by a process of fining (passing egg whites, ~ clay or other unsavoury substances through the fine to collect solid matter) and mechanical ...
Fining - The process of clarifying wine by removing suspended solids from wine before bottling. This is usually done by adding egg whites or another fining agent (like ~) that using ionic bonding to attract the solids and drop them out of the wine.
Yes every stave is tested for halo-anisoles. We test our oak just like you would test your cellar, using highly sensitive ~ trapping enhanced with blowers in conjunction with ETS Laboratories analysis.
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 ~.

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 "~" or the like is used.
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 ~ (a clay of hydrated magnesium silicates) to remove protein, ...
egg white, milk, blood, gelatin, carbon, casein (the principal protein constituent of milk and cheese) and isinglass (an extract of sturgeon bladders). Fining can lower high levels of tannin, remove haze and reduce color. Heat stabilization is another goal accomplished by fining, using ~ (a ...
