You might feel a bit silly tearing through the wine bins like you're searching for your dropped keys. And Cullen said that he feels that people think he's "weird" when he starts digging around in the wine section of the warehouse.
But he doesn't let that stop him, and for good reason. Cullen said that different vintages are often mixed up in the bins together. If you forgo rooting around, you risk missing out on the best vintage.
That's because different vintages tend to be thrown in the bins together.
"Don't just grab the first bottle," Reyes told Business Insider. She said that while vintage might not matter as much for lower-end wines, for high-ticket bottles it's far more crucial.
Cullen also recommended checking beneath the wooden racks, where you might find a forgotten bottle of an otherwise sold-out wine.
Either way, it's a mistake to leave the warehouse without doing a thorough investigation of the available bottles.
