I am experimenting with making my own vinegar for weed control. I use my Mr. Beer (2 gallon size) batch residue for the yeast and added 2 lbs of sugar. This ferments for 2 weeks and then I added 1/2 cup of Organic vinegar with Mother from the Health Store. This should have the vinegar bacteria and I will let this ferment for 2-4 weeks. I plan to test acid value to determine strength. So far, I have $2.20 in the batch to make 2 gallons. Normal 10% organic vinegar sells for around $9.00/gl. I usually need 2 gallons per summer to treat weeds. I will update this post with the results.
The bacteria are self limiting and will die if the acid concentration gets too high or oxygen too low. I will remove a little mother for the next batch and simply jug it up. It will keep as long as the cap is tight.
Vinegar strength is now at 9-10% so I will bottle it up as I have applied it to weeds and it killed in 2 days. I added 2 oz of orange oil ($15/QT) to each gallon so total cost per gallon is about $2.00. I am enjoying my backyard now watching the weeds die from my homeade vinegar while having a homemade beer! Microbes are great!
Just an update on vinegar use this summer. Total cost for 4 gallons- $8.00. It was all I needed for the weeds. I also used a gallon on my yard during fertilizing. I am keeping 1 gallon over the winter so I do not have to make it until it gets hot enough to grow the vinegar bac at the recommended temperature.
