Finish a 'Red wine' top....

[Kick]

I happen to have an uncle who owns a liquorstore. Perhaps he has some boxes of cheap wine that doesn't sell.

I'll keep this in mind for a future build

My brain says 'I don't think so'. I'm no expert but to my reasoning, red wine being organic would continue to break down over time (entropy), making it unstable (unlike inks and dyes). That might cause: (a) the stain to change colour, (b) the chemical reaction to cause damage to the finish or wood, (c) your hard worked and much loved axe to smell like a bottle of sour vinegar or worse, (d) all of the above or (e) some other disaster to occur. Then again, it could be (f) none of the above.

Haha, I think option d is the most probable

Haha, stain is cheaper indeed but what if you could tell all your friends that it took '100 bottles of Hardy's Merlot 2013' to finish it

It still can, just dont use it on your guitar

Tend to think it won't be colourfast and will most likely end up more brown than red as things age.

A while back a forum member tried beetroot as a staining property and the purple quickly turned brown once it started to oxidise.
