The Saaz Shine variety was registered in 2019. It was tested in two areas, Chrášťany (no irrigation) and Stekník (with irrigation), between 2017 and 2021. An average hop yield in Stekník is 2.62 t/ha and in Chrášťany it is 2.54 t/ha. No conclusive difference in yields was determined. An average content of alpha acids was 4.67% in Chrášťany and 3.18% in Stekník, therefore the content of alpha acids in Saaz from Chrášťany has been proven to be higher than in Stekník. There is a conclusively higher content of essential oils in hops from Chrášťany (0.65g/100 g) than from Stekník (0.34 g/100 g), but the composition of the essential oils is not conclusively different. The aroma of hop cones from both areas is identical. Their moderately intense scent can be described as a fine hop one with a background hint of fruit and citrus.
