Japanase Knotweed Vinegar Ingredients
- 1 cup lightly flavored vinegar - *a mildly flavored vinegar like white wine, champagne, or rice is ideal, but you can use white vinegar in a pinch - just dilute it by using 3/4 cup white vinegar and 1/4 cup of water
- 1/2 cup chopped Japanese knotweed


Step 1 - Add chopped japanese knotweed to vinegar and refrigerate

1. Place chopped knotweed in a jar and cover with vinegar. Store in the refrigerator and infuse for at least 48 hours, until the vinegar turns pink and takes on the bright flavors of the knotweed.

What does Japanese Knotweed Taste Like?

To put it simply: they taste like a more vegetal version of rhubarb! The flavor is sour and green, and the texture is crunchy and succulent. Use it where you’d use rhubarb, or anywhere you want a bright, punchy, and tart flavor. When infused into a vinegar, the flavor becomes quite citrusy and a bit floral – dare we say, like lemon juice?

How do I Prepare Japanese Knotweed?

Like any foraged green, proper preparation is key. Ants love Japanese Knotweed, so first be sure to thoroughly rinse the stalks. Then, remove leaves and tips from the knotweed – the best part is the stalks.
