To prevent such horror, wine accessory company Oenophilia invented Wino Sippers — a glass that's built with a straw feature to prevent teeth from getting stained.
Wino Sippers cost $24 for a set of two glasses, and each glass holds five ounces of wine. The glass fits right into your hand (kind of like a mug) so you can sip away without fear of spilling. After-all; we know that's alcohol abuse.
Of course you can always save yourself the $24 and just use a straw. Problem is finding on long enough to fit into the bottle. Don't act like you haven't thought about it.
