- Cone density: Moderate to tight
- Seasonal maturity: Mid season
- Yield amount: Moderate yield
- Growth rate: Moderate to vigorous
- Susceptible to: Verticillium wilt, downy mildew
- Resistant to: Some strains have been developed with resistance to various diseases
Oil and Acid Profiles
The oil and acid composition of Hallertau hops lends to the complex and subtle flavor. It contains a blend of essential oils that are harmonious with the traditional lagers and ales they are often used in.
- Alpha acid composition: 3.5-5.5%
- Beta acid composition: 3.0-4.0%
- Co-humulone composition: 18-25%
- Alpha-Beta ratio: 0.9-1.5
- Total oils (ml/100g): 0.5-1.0
Oil Composition:
- Myrcene oil composition: 20-30%
- Humulene oil composition: 35-50%

This composition gives Hallertau its characteristic floral, herbal, and spicy notes, with a hint of grassy character. The overall flavor profile can be described as a mixture of floral and earthy tones that complement the beer without overwhelming it with bitterness.
Its storability is moderate, meaning that while it can maintain its properties for a time after harvest, it should ideally be used as fresh as possible to preserve its delicate aroma and flavor contributions.
Cultivation and Usage
Growing and Harvesting
Hallertau hops, originating from Bavaria, Germany, have a rich history of cultivation dating back to the year 736. These hops prefer a specific microclimate found in the Hallertau region, which is known to be the world’s largest hop-growing area. Due to their susceptibility to diseases like powdery mildew,
Hallertauer Mittelfrüh, one of the primary varieties, requires careful management and a knowledgeable approach to cultivation. Harvest typically occurs early in the season and great care is taken to ensure that the crop retains its delicate aromatic properties.
Brewing Applications
Hallertau hops are renowned for their noble flavors and aromas, characterized by floral, spicy, and woody notes. The total oil content, including myrcene and humulene oil, lends a subtle complexity to the beer without overwhelming bitterness.
These hops are primarily used for their aroma contributions in traditional German beers such as lagers, pilsners, and wheat beers, and have found their place in crafting American lagers and Belgian ales. Brewers often use them in dry hopping techniques to enhance the beer’s bouquet.
Market and Substitution
While Hallertau Mittelfrüh remains a sought-after variety, it can be difficult to grow, leading to the development of more disease-resistant substitutes like Liberty, Crystal, and Hallertau Tradition. These varieties aim to capture the essence of the classic Hallertauer Mittelfrüh profile.
Brewers looking to purchase these hops can browse various online stockists such as Yakima Valley Hops, Hops Direct, and Great Fermentations. Despite substitutes, the unique Hallertau aroma and flavor profile make the original variety irreplaceable for many aficionados.
