I guess most of you guys already know
that a lot of fruit/vege juice can be use as ph indicator.
But I think I found a new one!
Hint : the comes in 750cc green bottles.

This morning when I was doing the dishes,
I filled the wine glass with tap water, it started out purple as expected.
Then it turned deep blue all by itself.
Humm..this is interesting.
So I put a drop of soap in it, and it turned back to purple.
Now if i can just get some acid to test it.
Tabasco! Just a drop of tabasco and the whole glass turned red!

I know grape juice are pH sensitive, but fermented?
It's fun because you only need a few drops,
and you can do whatever you want with the rest.
