A Georgia-based sweet onion certifier has added another grower to its roster.

Collins, Ga.-based National Onion Labs Inc. announced Aug. 11 that Bakersfield, Calif.-based Country Sweet Produce has contracted to have its onions tested for sweetness, according to a National Onions Labs news release.

All of the onions grown by Country Sweet and tested thus far by National Onions Labs have met the company’s Certified Extra Sweet or Certified Sweet standards of sweetness.

National Onions Labs was founded in 1998 as a certifier of Vidalia sweet onions. It has since expanded its services to include other growing regions.
