Question: What is a simple explanation of fining & racking during wine making and why do it?
Answer: Some particles during wine production are not heavy enough to fall out of the wine by itself and remain suspended – such as very small dead yeast cells. This “cloudiness” can be cleared making the wine look brighter if the wine is fined by adding a substance (like egg whites, gelatine, isinglass, or bentonite) to precipitate them out so that the wine can then be racked (separation of the wine from the sediment) into another container. Some producers are against fining but even more are against filtering in the belief that it might strip essential aromas, colour, and flavours from the final wine.
