After You Buy From The Antique Wine Company, How Do You Know The Wine's Age?
Reputable companies like these have super sophisticated techniques for verifying the authenticity of a bottle's age. They can utilize particle accelerators, and ion beams to literally determine the exact age of a bottle's glass, and therefore the wine contained therein. However, figuring out that for yourself is something different.
I don't know about you, but I don't have a particle accelerator at home, so I have to go off of visual cues. Given any type of red wine, you simply need to look at what type of red you're seeing in the glass, to really determine how well the wine has been aged.
Most typically a young wine is going to appear to be a purple-ish red. More reflecting the color of the fruits that went into the making of the wine. This occurs when the wine has not been aged for very long at all. But remember that's not bad, because not every wine needs to be aged 25 years for flavor. With most varieties there's no benefit to the aging process.
Usually you're going to see a ruby or garnet colored red. This is a sign that the wine has been aged more appropriately. That means a process that likely takes a few years or more. This is the height of maturity for any wine, and usually when the flavors are at their peak. Ruby being the younger, and a garnet being a slightly more aged variation.
Finally, a red brown wine is one that's starting to edge back down from it's height. Meaning that the wine is still healthy, and still has the flavor you're looking for, but has already hit the peak flavor potential. If you're looking for a well aged wine, this is the color you want.
