There's a lot more to wine than just type, color and alcohol content, but you really don't need to know a whole lot more than that to enjoy wine. Wait, let me rephrase that- there's not much more to know if you want to enjoy wine casually rather than embracing the science and the culture like a vintner or sommelier.
Most of us started out drinking wine for that warm and fuzzy feeling the alcohol provides but soon found ourselves wanting to learn more about wine to enhance our enjoyment of the drink.
Well, whatever you want to know aside from a breakdown of varieties, flavors or prices is probably covered on this chart created by Wine Investments appropriately entitled A Beginner's Guide To Wine. Cheers!
