Chemical and Brewing Values
Sorachi Ace alpha acids range from 11–16%, averaging 13.5%. These acids are crucial for bittering when hops are boiled. Brewers use this percentage to calculate International Bitterness Units and balance malt sweetness.
Beta acids for Sorachi Ace are around 6–8%, averaging 7%. Unlike alpha acids, beta acids don't contribute much to bitterness during boiling. They are important for aroma evolution and beer stability over time.
The alpha–beta ratio for Sorachi Ace is between 1:1 and 3:1, averaging 2:1. Co-humulone makes up about 23–28% of alpha acids, averaging 25.5%. This influences bitterness perception, with higher levels creating a sharper bite and lower levels a smoother taste.
Hop Storage Index for Sorachi Ace is about 28% (0.275). This indicates good storage stability but warns of degradation at room temperature for six months or more. Cold storage is essential to preserve alpha acids and volatile oils.
- Total oils: 1.0–3.0 mL per 100 g, average ~2 mL/100 g.
- Myrcene: 45–55% (roughly 50%) — provides citrus, fruit, and resinous top notes but evaporates quickly.
- Humulene: 20–26% (about 23%) — adds woody, earthy, and herbal tones that persist longer than myrcene.
- Caryophyllene: 7–11% (around 9%) — brings spicy, peppery character and supports depth in the mid-palate.
- Farnesene: 2–5% (near 3.5%) — contributes green, floral nuances that are subtle but noticeable in dry-hop aroma.
- Other components (β-pinene, linalool, geraniol, selinene): 3–26% combined, shaping complexity in aroma and flavor.
Understanding hop oil composition explains why Sorachi Ace behaves differently at various stages. High myrcene content gives bright citrus and tropical notes during late or dry hopping. These terpenes are volatile, affecting aroma survival during whirlpool rest or extended dry-hop contact.
Humulene and caryophyllene provide stable woody and spicy elements that endure heat and time. Farnesene and minor alcohols like linalool and geraniol add delicate floral and geranium-like lifts. Crop year variability means checking current spec sheets is crucial before finalizing a recipe.
When planning bittering and aroma targets, use Sorachi Ace brewing values as a guide. Calculate IBUs from alpha acid percentage, consider HSI for inventory turnover, and match additions to hop oil composition for the desired citrus, herbal, or floral profile in the finished beer.
