Chemical and sensory characterization of new Czech flavor hop varieties (Juno, Saturn, Pluto, Ceres, Eris, and Jupiter) with evaluation of drought and disease resistance
Original language description
This study characterizes six new Czech flavor hop cultivars – Juno, Saturn, Pluto, Ceres, Eris, and Jupiter – using long-term datasets (2015 – 2025) that integrate chemistry, sensory profiling, and stress-resistance testing. Across cultivars, alpha acids were consistently moderate (4.6 – 7.2 % w/w), while total hop oils spanned 0.68 – 1.57 % w/w. These compact ranges, coupled with specific aroma profiles, support their suitability for dry hopping. Sensory results showed clear differentiation: Juno, Saturn, and Ceres expressed fruit-forward profiles, Pluto and Eris were citrus-driven, Jupiter exhibited a heavier woody-spicy character. Stress-tolerance assessments highlighted robust agronomic performance in several cultivars. Juno, Saturn, and Ceres combined favorable aroma with improved drought tolerance, among breeding lines tested in parallel, drought resistance frequently exceeded that of registered checks. Disease screening against downy mildew (Pseudoperonospora humuli) revealed high resistance in Saturn and very good resistance in Juno, Eris, and Ceres, whereas Pluto and Jupiter were less resistant. Overall, the new Czech flavor hops deliver modern aroma signatures with moderate alpha acids and practical advantages in drought and disease resilience. These traits have already driven adoption in Czech craft breweries and position the cultivars as versatile options for lager and top-fermented styles, particularly in dry-hopped applications.
