A seven-year study conducted by Tetyana Kondratenko, a professor at the Institute of Horticulture of the National Academy of Sciences of Ukraine, has found that Jonagold apples grown in Podil and Transnistria have the best taste and appearance. The study revealed that these apples had the highest soluble solids and sugars, and the least amount of organic acids, resulting in a sweet and sour taste rated at 8.4–8.6 points. However, Jonagold apples grown in the Southern Steppe had excellent taste but lacked sufficient color covering. Apples of the same variety from other zones had more organic acids and a harmonious sweet-sour taste rated at 8.0–8.2 points.
