Top 10 weird wine ingredients

28th February, 2013 by Andy Young

10. Fining agents – blood powder, egg whites and isinglass

EggsAlthough not strictly ingredients nor added for flavour, some strange things may have gone through a wine prior to bottling during the fining process. The point of fining is to add something that will create an enzymatic bond with particles in the unfinished wine that cannot or are unlikely to be taken out during filtration.

In the past the rather terrifying sounding “blood powder” was used. Now egg whites, casein, gelatin and the famous isinglass (made from fish swim bladders) are more common.

Other fining agents include bentonite clay and charcoal – which is apparently particularly good at removing phenols that contribute to off-colouration and bad odours.
