Irene Jiang/Business Insider We recently hosted a Sam's Club wine tasting, trying out seven different Member's Mark offerings. Member's Mark is one of Sam's Club's private-label brands, and it boasts its own line of wines. These Sam's Club selections ended up provoking some strong reactions among our six reviewers. Tasters dished out unreserved praise, scathing criticism, and general "meh" reactions — often when describing the same exact wines. One thing that many of the reviewers did agree on was that most of these wines from the Walmart-owned retailer are worth their price. Sign up for Business Insider's retail newsletter, The Drive-Thru.

The private-label brand, which set about expanding its proverbial wine cellar in 2017, is sold by Walmart's members-only warehouse chain.
