  1. Jeff,
    Your products are terrific. I love the crunch of the Zauerkraut. It defines what sauerkraut should be: tangy, crisp and fresh. The Zymchi is a staple in our fridge, Thanks for healthy and delicious products.

    Jim and I tried the Zymchi today and bought a jar. We were at the St. Ann farmer’s market. The sour kraut was great and the zynchi was wonderful. We will be repeat customers and will tell our friends. Great job. thank you.

    My husband and I tried your Zymchi at the Mileager’s Indoor farmers market this past Sunday. We loved it and will be back to purchase more!!!

  4. Bought some of the Zymchi at the Milwaukee Indoor farmers market today, for my kimchi loving husband, who developed his love of it when serving in Korea in the ’70’s. We both loved it! Zesty, intricate, nuanced flavor unlike any other we’ve tried.

  5. Some years ago I had my first taste of kimchi at a local Korean restaurant and recall being thoroughly unimpressed, actually with that entire meal. What a pleasant surprise and delicious taste treat it was, by contrast, to recently sample my first spoonful of Zymbiotics Zimchi, a whole different animal altogether. The zingy flavor really “pops” and the ginger flavor really comes through in a most beguiling way. Needless to say, I have gone from being a kimchi naysayer to becoming hopelessly and joyfully addicted to this outstanding and super-fresh tasting product…

    I just purchased my second jar of Zimchi at Metcaff’s Sentry in Tosa and am finishing my jar of carrots as I write this. I love, love, love your products! Thank you.
    I certainly hope you do well in the future.

  7. Bought your Zimchi today at Outpost as an addition to the bibimbap I made. HUGE raves from my family, kids included! Nice and tangy with just a hint of heat. Delicious!

    I bought a jar of Zimchi about two weeks ago at Woodman’s in Oak Creek and would you believe that once I let my husband taste it he finished the entire jar. Being from a military family I as well as many of our friends and family have eaten Korean style kimchi and I got to say, Zimchi is so much better. Now I cant leave Woodman’s without 2-3 jars. Great tasting product! Wish you much success.

  9. I purchased Zimchi, Zauerkraut, and Ginger Zarrots a few months ago. I’ve just recently dove into the jars. I’m in love. I was even able to get my boyfriend to try each of the products and fermented foods aren’t his thing.

    Thank you for creating such a wonderful product.

  10. Jeff- Thanks for being at the Waukesha farmer’s market today. I bought some Zimchi this morning and made my wife some fish, Jasmin rice, and peas topped with your Zimchi for supper. Delicious! Hope to see you back there again!

    I bought a jar of the Zymchi last Saturday. It was totally gone by Monday evening. Must stock up for the winter!

    “The proof of pudding is in the tasting.” Or the Zimchi, or the Zauerkraut. Bought both at the Milwaukee Indoor Farmer’s Market @ Mitchell Domes, and it was BRILLIANT to offer samples. Thank you! One taste, and you know they’re great, they’re worth it! Took the Zauerkraut for my soon to be 86 year old Polish mom, (she should know) and she tasted, cocked her head, eyes went up as she savored, and she smiled and nodded. It’s the real deal people. Treat yourself, and the probiotics are a bonus!

  13. I am on my third jar of Zymchi. Not only am I enjoying the flavor.. I’m also enjoying the health benefits. I’m noticing a definite reduction in my Inflammation levels. I’ve thought about trying the other two flavors ….. but I’m hooked on the Zymchi.

  14. Wow! I tried Kimchi in the past and didn’t like it…I sampled Jeff’s Zimchi and was sold! Eating healthy feels good and great taste is an added benefit!
