QED stands for “Quod Erat Demonstrandum”—Latin for “Which was to be demonstrated.” At the end of a mathematical proof, you typically write QED. It basically means “I’m done; I’ve proven what I set out to prove.”

When we started our winery, our family and friends would say “You guys know a lot about wines, but can you make world class wine?”

Well, the proof is in the bottle – QED.
