What You Need To Know
Sauerkraut isn’t for everybody. The pungent acidity of fermented cabbage can be polarizing, but fans of this zesty condiment swear by its ability to add refreshing tang to rich meats or hearty potatoes. To find out which kraut is king, we tried six nationally available supermarket sauerkrauts plain, with hot dogs, and in pierogi. Sauerkraut has a similar tanginess to pickled foods, but unlike most supermarket pickles, sauerkraut contains no vinegar. Instead, it gets its acidity from fermentation: Shredded cabbage is sprinkled with salt, packed in containers, and left to sit at room temperature for 1 to 6 weeks. During this time, natural bacteria and yeasts eat away at sugars in the cabbage, leaving behind tart lactic acid in their wake. Once manufacturers deem the sauerkraut suitably tangy, it’s packed into jars, cans, or bags along with some water to prevent browning.
While it only takes three ingredients to make sauerkraut—cabbage, salt, and water—our tasters detected “off,” “chemical” flavors in three lower-ranked sauerkrauts. A peek at ingredient labels revealed that these products all added sodium benzoate and sodium bisulfate—preservatives that extend shelf life. With so few other ingredients to mask off-flavors, sauerkrauts with chemical preservatives had a prominent “fizzy,” “sulfuric,” almost “ammonia-like” quality, even when tasted atop hot dogs or in pierogi. Tasters preferred products that contained just the core three ingredients, calling them “fresher,” “brighter,” and “classic.”
Since salt enhances flavor, it wasn’t surprising that our favorite products also contain more sodium. We liked the “punchy,” “zippy” flavor of sauerkrauts with 200 milligrams of sodium or more per 2-tablespoon serving. No kraut was too salty for tasters, who thought more salt made for kraut with a hearty, fermented flavor; those with any less just tasted like wet cabbage.
What did surprise us, though, was that these sharper, brighter-tasting krauts were packaged in shelf-stable jars or cans, while lower-ranked products were packed in refrigerated plastic bags. Though we often assume that the products we buy in the refrigerated section of the supermarket are fresher than their shelf-stable counterparts, our science editor explained that in this case, they’re not. Unlike jars and cans, plastic bags let in small amounts of air over time, which degrades some of the sauerkraut’s pungent flavor. This is also why bagged products are the only ones to add preservatives: Unlike the canned and jarred krauts, their packaging alone isn’t enough to prevent the growth of microorganisms.

Everything We Tested
Recommended
With a “slight sweetness” and subtle notes of “zing” and “funk,” this jarred kraut lent a “bright” tanginess that “complemented” but “didn’t overpower” the main dish. Tasters thought this product’s “smaller” shreds were “soft,” with “just a bit of chew,” perfect for piling atop hot dogs and stuffing in pierogi.
This canned kraut was “bright” and “almost citrusy,” with “good tang” and a “subtle punch” of bitterness. Tasters liked that its “finer,” “more tender” shreds provided a “subtle crunch” and “clung nicely” to hot dogs.
Recommended with reservations
This “finely shredded,” “slightly crispy” canned sauerkraut nailed the ideal texture but fell short on flavor. Most tasters found this product “lacking in punch” and a bit “too mild,” though a few appreciated its “less pungent” tang.
With the lowest sodium of the bunch, this bagged brand was “vegetal” and “very mild,” bordering on “bland” for some tasters. Tasters liked that this kraut’s shreds were “smaller” and “more even” than other bagged brands, though a few noted some strands were “tough” and “squeaky.”
Though “moderately tangy,” with a “mild flavor” that was appreciated by some conservative tasters, this bagged kraut was permeated by a “chemical,” “almost chlorinated” sourness. Most tasters thought this brand’s texture was “rubbery” and “overly crisp,” “more like shredded cabbage than sauerkraut.”
Tasters were put off by this bagged brand’s “really uneven shreds” and “chewy,” “plastic texture.” Some also noted a “sour,” “yeasty” flavor, though most were fine with this brand’s “moderate” tanginess, especially in pierogi, where off-flavors were masked by other ingredients.
