Green Spring Technology's Hop Extracts Enhance Craft Beer Formula Innovation

Hops (Humulus lupulus L.), the “soul” of beer, not only impart their distinctive bitterness and aroma but also serve vital functions such as inhibiting bacterial growth, preventing spoilage, and maintaining foam stability. Today, with the booming craft beer industry, the demand for precise control over hop flavor profiles has become increasingly prominent.

Green Spring Technology, deeply rooted in the hop extract field, has launched a new generation of hop extract products based on extensive research into over 400 flavor compounds. This series overcomes the limitations of traditional raw materials by achieving precise control over flavor substances through innovative technology, providing craft brewers with more stable and creative ingredient solutions.

Compared to traditional raw materials, Green Spring Technology's hop extracts offer the following distinct advantages:

· Precise flavor profile control ensuring high batch-to-batch consistency

· Complete preservation of active hop components, enhancing beer flavor complexity

· Adaptability to diverse brewing processes, meeting customized formulation needs

1  Green Spring Technology Hop Extracts: Empowering Craft Beer Flavor Innovation Through Science

Hops are the soul of beer, with their flavor compounds and stability directly determining beer quality and character. Leveraging deep research into hop flavor compounds, Green Spring Technology transforms the flavor mysteries of natural hops into stable, efficient, and precisely controllable extract products through technological innovation. This provides solid assurance and boundless possibilities for craft brewers' recipe innovation.

1.1 Precision Control and Solutions for Bitterness Compounds

The α-acids, β-acids, and polyphenols within hop glands are the core sources of beer bitterness. Through scientific methods, Green Spring Technology achieves precise control over these compounds:

☆ Efficient Conversion and Stability of α-Acids

Through optimized processes, α-acids are efficiently converted into iso-α-acids during boiling, ensuring highly stable and predictable International Bitterness Units (IBU) values. This guarantees precise reproducibility in recipe design.

☆ Preservation of β-Acids and Flavor Freshness

Maximizes retention of β-acids and their oxidation products, effectively counteracting bitterness decline during beer storage. This significantly extends flavor freshness and consistency.

☆Precise Polyphenol Management

 By controlling polyphenol types and levels, we reduce astringency from excess polyphenols, delivering pure bitterness and smooth mouthfeel for enhanced beer drinkability.

Green Spring Technology's bitterness extract products drastically reduce bitterness fluctuations caused by raw material batch variations, providing brewers with a reliable “flavor constant.” This allows them to focus on flavor creativity and pairing experiments, accelerating new product development cycles.

1.2 Analysis and Stabilization of Aroma Compounds

Beer aroma originates from hop essential oils, comprising only 0.5%–3.0% of the total, with complex and volatile compositions. Through advanced analytical and extraction technologies, Green Spring Technology achieves precise control over key aroma components:

★ Superior Retention of Key Aroma Compounds

Focusing on high-boiling-point, stable oxygenated compounds (e.g., terpenols, esters), process optimization enables efficient extraction and protection, ensuring their characteristic aromas are fully preserved in the final product.

★ Effective Reduction of Undesirable Flavors

Targeting sulfur compounds and aldehydes/ketones prone to mold growth and green off-flavors, process controls significantly reduce their levels, safeguarding the purity and pleasantness of beer aroma at the source.

Green Spring Technology's aroma extract products effectively resolve the issue of aroma fluctuations in natural hops caused by variety, vintage, and storage conditions, delivering highly consistent and predictable aroma performance in every batch.

1.3 Comprehensive Solutions: Empowering Craft Beer Formula Innovation

Green Spring Technology is committed to translating complex flavor science research into simple, easy-to-use ingredient solutions:
