Good balsamic vinegar can sound like an ingredient reserved for foodies with deep pockets and fancy restaurants. However, it belongs in every home kitchen. Fortunately, you don't have to pay an arm and a leg for a quality option. When Consumer Reports revealed its rankings of bottles priced under $20, it named Costco's Kirkland Signature Organic Balsamic Vinegar of Modena as the best all-around choice.

The review declared, "If you're going to stock just one balsamic, this is it." It went on to praise the flavor as "sweet, tangy, and fruity, with a bit of spice." Consumer Reports additionally noted that this item has the ideal consistency for drizzling. It hails from Modena, Italy, an area that has been making balsamic vinegar for around 1,000 years. The distinctive history and high quality of the products have earned them protected designations that ensure buyers are getting the real thing. The brand behind Kirkland balsamic is Acetum, whose connection with Costco reportedly dates back to 1999.

The retailer's partnership with Acetum has stood the test of time, but the price of this vinegar hasn't. While it cost just $14 when Consumer Reports reviewed it in December 2025, it's now just a hair under the $20 limit. As of this writing, it sells online for $39.99 for a two-pack.

Some customer feedback is just as positive as Consumer Reports'. The Kirkland Signature Organic balsamic earned 4.8 out of 5 stars with around 500 reviews. One shopper who praised it wrote, "[T]op shelf product, great value too." Another remarked, "Rich, bold, well aged, fruity, thick. As long as Costco keeps carrying, I will buy." Someone else shared, "Tried other brands and they can't compare."

Although Consumer Reports gave Kirkland its top all-around honors, it also named a few other superlatives worth considering for those who use their balsamic in particular ways. Those who primarily use it for dressings should grab Trader Joe's Gold Aceto Balsamico Di Modena, while shoppers who prioritize low prices above all else might find what they're looking for with Filippo Berio Balsamic Vinegar of Modena. What they all share is a stark difference in affordability compared to various high-end alternatives. Aged balsamic vinegar from Modena can be extremely pricey, with some 3.3-ounce bottles selling for over $200 apiece. But as the Kirkland Signature version proves, you could spend 10 times less and still get a quality product.
