The Crystal hop has a distinct aroma and flavour profile that includes notes of wood, green floral, and fruit with herb and spice accents of cinnamon, nutmeg, and black pepper.

The alpha acid content in Crystal hops can vary from crop to crop, but typically falls within the range of 3.5% to 6.2%. This moderate alpha acid content sets Crystal hops apart from other varieties and contributes to their well-rounded flavour profile.

Longer boil times result in the isomerization of more alpha acids, leading to increased bitterness in the final beer.

The total oil composition of Crystal hops includes Myrcene, Humulene, Caryophyllene, and Farnesene, each contributing distinct flavours and aromas. Myrcene imparts resinous, citrus, and fruity notes, while Humulene adds woody, noble, and spicy flavours. Caryophyllene contributes pepper, woody, and herbal notes, and Farnesene adds fresh, green, and floral flavours.
