Wines without sulfites

[Thomas]

ww, you mispeak. The majority of wines on the planet have sulfites added to them during the winemaking process and then some have it adjusted before bottling. Red wines require lower doses, generally, than do whites. Sulfites protect against oxidation.

If your friend is asthmatic, then he/she is smart to be wary, however, the sulfite levels in wine are quite low, and there is scant information regarding asthmatics reacting to wine.
