Don't it make your red wine, blue

[GreginND]

Has anyone else observed this before? I see it all the time here as our water is definitely on the alkaline side. This is some deeply colored MN1220 (an unnamed cousin of Marquette). You can see the anthocyanins change color when they are deprotonated. I love chemistry.

Bwahahahahahaha...... Very cool!

It isn't just your water. Our water does that also for Mn1200, Frontenac, Leon Millot and any other deeply pigmented wine. It also does it with elderberry wine. I always figured it just turned blue when diluted- didn't know the chemistry behind it.

It isn't just North Dakota water. I am in Missouri on city water. It happens so the time for us with almost all red wines.

It must be the chorine

No chlorine. Our city uses ozone. The color change is due to the alkaline water shifting the ph. The anthocyanins change color from red to blue. Not unlike red cabbage changing to blue with baking soda.

That's cool! :> Wish my water did that.
