While Trader Joe's Fearless Flyer and social media accounts offer monthly specials that pique interest, shoppers have come to appreciate a different secret in the wine section.

TJ's marketing director Tara Miller suggested shopping from the end caps, as they contain "the wines that sell at the highest rate [...] those are gonna be really good."

Trade Joe's approachable price point, coupled with the wine buyer's knowledge, could make this tip very valuable and offer an opportunity to expand your horizons.

Some Trader Joe's wines might not have the winery's name on the label. While people may think the lack of information is a mistake or a bait-and-switch, the decision is intentional.

TJ's wine might be made by a well-known brand. Winemakers prefer to keep their partnership secret, as a bottle from the same winery may sell for double at a liquor store.

However, "Inside Trader Joe's" podcast co-host Matt Sloan explained that TJ's wine labels have a lot number that references a particular winery.

Even if the vintage is offered or another version of a particular wine, the same lot number is used. Remembering the lot number might lead to rediscovering a favorite sipper.
