Variety description

10 August 2026

The variety is classified as a revived cultivar, re-introduced into small-scale production to satisfy the demand for original aromatic profiles. It is actively used in modern beer styles such as IPA, Pale Ale, and Pilsner.

The aromatic profile includes pronounced notes of coconut, complemented by shades of blood orange, apricot, mango, pineapple, and mandarin. The chemical composition is characterized by a beta-acid content of about 2.8% and a total oil volume of approximately 1.7 ml per 100 g of product.

Myrcene, humulene, farnesene, and caryophyllene predominate in the essential oil composition. Currently, the variety is grown in Poland on limited acreage; information on the morphological traits of the plant and detailed agrotechnics is absent from open publications.
