Description
Bentonite is widely used in wine clarification and stabilization around with world. It is relatively inexpensive and easy to use, however it is inefficient and the cost to the industry has been estimated at around $1 billion. Consequently, much research has been directed at improving bentonite efficiency and developing effective alternatives. Recent pilot studies have proven effective in reducing the amount of wine lost as lees by using inline dosing of bentonite and by protease addition and juice flash pasteurization prior to fermentation. Other recent developments in bentonite alternatives include carrageenan and zirconia additions as well as more research into effective proteases. This presentation will provide details on these latest advances in developing bentonite alternatives.
