The hybrid's ripening periods vary depending on the region: from early-maturing (110 days) to mid-early (90–100 days) or late-maturing. The plants have good vigor and an upright habit, which ensures resistance to lodging and convenience during harvesting.
The heads have a round shape and a dense internal structure; their weight ranges from 2.5–3.5 kg to 6.0–7.0 kg. The hybrid is suitable for fresh market sale and for processing, including fermentation. Intended for cultivation in temperate climates.
