At Sour Flower, we turn Hawaiʻi’s overflowing fruit into vibrant, small-batch vinegars—each one alive with flavor, rich in nutrients, and completely unique.

All of our vinegars share one powerful benefit: acetic acid, the core compound that supports blood sugar balance, digestion, and metabolism. But each fruit brings something different to the table—its own mix of polyphenols and antioxidants that help feed different microbes in your gut.

And the more microbial diversity you support, the stronger and more resilient your body becomes.

So why stick to just apples?

With our vinegar subscription box, you’ll get a rotating variety of fruity, bold, and totally original vinegars delivered right to your door. These aren’t just for salad dressing—try them in cookies, smoothies, steak sauces, stir-fries, even on fresh fruit or bread.

Now that you’ve got a steady supply, don’t hold back. Use the whole bottle. Try everything. Create boldly.

Sour Flower Vinegar

Each batch of vinegar is a singular creation, never to be repeated. A fleeting moment eternalized through fermenation. An eternal elixir.

We brew with the whole fruit, not just the juice, thus creating a potent polyphenol content and antioxidant profile. Imagine all the essential oils and flavors that are held in citrus peels?! It comes through in our full spectrum fruit vinegars.

Join us on the vinegar flavor odyssey as we co-create combinations that have never been made. Afterall, creativity is the true secret to a thriving life.

Experience novelty.

Fermentation

Anyone with fruit trees knows that processing fruit can be quite a challenge. It can be harvested, sold, preserved, or sadly, go to waste. Many homes have more fruit than they can handle, and we’re thrilled to turn that surplus into vinegar. It’s been wonderful to see our community rally around the idea of rescuing fruit together. Many of our creations are inspired by what others choose to share, and we’re truly grateful for that! Let us be your "composting" friends, ensuring that nothing goes to waste!
