Kirin II Hops: Profile & Substitutions
Description
Kirin II is a cornerstone of Japanese brewing heritage, representing a meticulous effort by the Kirin Brewery Hop Research Farm to perfect the "Noble" hop within Japan’s unique climate. Developed from a cross of Saaz and White Vine, this variety was designed to bridge the gap between the spicy elegance of Czech landrace hops and the agricultural requirements of the Nagano and Tohoku regions. Due to its status as a major variety in Japan, it is often grown exclusively under brewery contracts, making it a professional-grade staple for the domestic industry. Kirin II is defined by its restraint and purity; it remains a favorite for brewers who value the subtle, sophisticated balance required for world-class lagers, offering a polished finish that is both traditional and uniquely Japanese.
The profile of Kirin II is a serene and intricate arrangement of early spring blossoms and mild herbal spice. It leads with a primary bouquet of wildflower honey, sweet hay, and dried lavender, followed by a sophisticated secondary layer of soft lemon zest and a whisper of white pepper. Because of its high farnesene and humulene content, it lacks any harsh resinous edges, providing a "silky" aromatic presence that integrates perfectly with the delicate rice and pilsner malts common in Japanese brewing. On the palate, the bitterness is incredibly gentle, leaving a crisp, refreshing, and slightly earthy finish. It is the definitive choice for brewers seeking a "luminous" hop character that emphasizes elegance, tradition, and absolute clarity.
