This may not be such an issue at the holidays, since it seems like there are always people around, but do you ever yearn for a glass of wine, but hate to open a new bottle because you know you won't (or at least you don't plan to) finish it?
If so, let me introduce you to Stacked. What is it? A tower of four individual cups of wine that snap together to equal a full bottle. It's perfect for sharing. Or not. For on the go, since it's already in a glass. Or staying at home, since you won't have to dirty any additional dishes (did I mention it's already in the glass?). It currently comes in four varietals: cabernet sauvignon, chardonnay, merlot, and pinot grigio. And, if you only feel like one glass, you no longer have to worry about wasting the rest of a bottle.
*Disclaimer: Stacked Wines has no idea who I am and they didn't ask me to say nice things about their product. I just wanted to share a new product that I found fun and innovative.
