Dealing With Haze

MEMBERS ONLY

While haze can sometimes just be aesthetically off-putting and not a true flaw, it’s something many winemakers like to avoid. Get the scoop on reducing haze and other benefits, as well as drawbacks, that come with the use of fining agents.

Rules Of Fining

MEMBERS ONLY

Indeed, after using most fining agents there will be a layer of sediment generated and you’ll need to rack the wine off of it accordingly. Fining agents, by definition, are introduced into a wine to interact with whichever of the wine compounds you are trying to mitigate or reduce. For instance, bentonite is a natural

Fining Red Wines

Red wines are typically not fined as often as white wines, to which we often add bentonite in order to remove potentially haze-causing proteins. The tannin from the skins of red wines tends to bind with excess protein, the agglomeration of which will precipitate out during the fermentation process. Nor do we usually cold-stabilize red
