Should distilled or filtered water be used in making wine?
The easiest answer to this question is if you enjoy drinking your water, you can make your wine with it. The high levels of acids and minerals that are in a wine kit itself make any content in the water you use negligible. Chlorine levels in the public water supplies are federally regulated and are not high enough to affect your wine. Chlorine also dissipates very quickly into the atmosphere so any perceived flavour will dissipate during fermentation. If your house is equipped with a salt exchange water softener, that water can’t be used for winemaking because of the high levels of sodium.
