Variety description

10 August 2026

The plant has high vigor with a semi-erect or spreading crown and medium shoot-forming ability. The nuts are medium to medium-large in size, have a round, slightly flattened shape, and a thick brown shell. The kernel yield is 40–50%.

The variety is late-maturing; the fruits fall in the second half of September. The tree shows pronounced protandry and requires a specific number of chill hours for flowering. The variety is sensitive to the hazelnut bud mite and is not suitable for planting on calcareous or dense soils.

The variety's produce is in demand in the confectionery industry, and the plant itself is recognized as a reliable pollinator for a number of other hazelnut varieties. In international practice, the variety is often compared with the Barcelona variety due to historical confusion in names.
