Vivienne Harr and Fair Trade USA will introduce "Make a Stand Lemon Aid" at Molsberry Market in Santa Rosa on Sunday.
The organic bottled beverage will be sold in grocery stores across the Bay Area and customers can pay what they choose. Half of the profits will go to organizations that work to end child slavery.
Harr raised more than $100,000 last year when she set up a roadside lemonade stand in an effort to combat human trafficking.
