I wonât be dabbing the dark stuff on my wrists anytime soon, but I always wondered if there was a cheaper alternative when I need the flavor services of deep, quality vinegar without emptying my wallet. Enter Chinese black vinegar. Donât call it soy sauce. Black vinegar is similar to regular rice vinegar (both are made from rice) but black vinegar is aged for a more mellow, complex and rich flavor as well as enhanced nutrient content, while rice vinegar maintains its sharpness and has a narrower flavor profile.
When vinegar reaches soil level it is quickly neutralized so that it is no longer acidic. The acetic acid in vinegar is converted to harmless acetate salts which have little effect on the weed. The weed just regrows and in a week or so, the weed is back. Vinegar is not a natural weed killer. Vinegar is about 5% acetic acid, the rest being water. Pickling vinegar is about 7% acetic acid, but even this is not strong enough to kill weeds. A higher concentration of acetic acid will kill some plants, but you need to use at least 20% acetic acid.
