I have an old bottle of Mateus Rose sogrape portugal wine. It does not have a vintage date on it, but must have been sitting around my house for 20 years easy. Is it still good to drink or has it been overaged and now no longer any good.
Would appreciate any help.
This is a low cost industrial wine made for ready consumption.

In other words: "no".
But do try it. Don't expect to enjoy it, but at least you will then know how such wines develop.
This is a low-quality, low-priced wine made for immediate consumption. It should never have been aged at all, and should have been drunk (if at all) when first bought. So it's likely to be terrible now.
But it won't poison you; it just won't taste good. If it were me, I'd never throw away any bottle of wine without first opening and tasting it. It's not likely, but surprises do occur.
