Description:
Bobek is a diploid hybrid between Northern Brewer and a TG seedling of unknown origin

Breeding Properties:
It is a medium late variety, its optimal picking time in Slovenia being between August 28th and September 5th. The plants have a form of a dense cylinder or basket, thin and marked­ly branched lateral shoots, with characteristical short internodes, so that the bloom set can be well over the average. The vines are thin, rough, of green - purple - greyish colour. The leaves are small, of deep green colour, with typical dense venation. The rootstock is suscep­tible to downy mildew, the leaves are resistant and the cones slightly sus­ceptible. The expected yield is about 2000 kg/ha. It has a well deve­loped root system. It is grown on moderately deep and deep clay soil. It is grown in Slovenia. Large planting distance is required. The re­commended pruning time in Slovenia is between April 1th and 10th. An average cone is 20 mm long and the average weight of 100 dry cones is 12 g. They are small, of round shape, dense, of green colour and do not get shattered when picked by a picking machine. The drying tem­perature does not exceed 65 °C.

Characteristic Ingredients and Brewing Quality:
Bobek has an intense and pleasant hoppy aroma. It contains 3.5 - 7 % of α - acids (28 - 34 % of cohumulone). The ratio between α - and β - acids is about 1. The essential oil content varies from 0.7 to 4.0 % of dry hops. The ratio between α - humulene and β - caryophyllene in the essential oil is about 3. Bobek has a good storage stability. Beer prepared with this variety has good organoleptical scores for its bitterness and aroma. It is worth mentioning that among all the hop varieties in Slovenia this one has the highest content of β -acids.
