Pelletized Centennial hop is a globally traded brewing input, typically supplied as dried hop pellets (commonly Type 90) for bittering, aroma, and dry-hopping applications. Centennial is a U.S.-origin cultivar from the USDA breeding program in Washington State, and commercial supply is closely tied to the U.S. Pacific Northwest hop system and merchant/processor networks. The broader global hop industry is concentrated in a small set of producing countries (notably the United States and Germany), and international trade is shaped by annual harvest cycles, contracting, and cold-storage inventory management. Demand exposure is strongly linked to the beer sector (including craft and hop-forward styles), with buyer specifications centered on alpha acids, essential oils, moisture, and oxidation/stability indicators.

Specification
Major VarietiesCentennial
Physical Attributes- Pelletized form produced from milled dried hop cones (commonly Type 90 pellets in global trade).
- Olive-green cylindrical pellets are a typical visual descriptor for standard hop pellets.
Compositional Metrics- Alpha acids and beta acids are core buyer specifications; Centennial alpha acid is commonly reported in a crop-year-dependent range (USDA cultivar record provides reference ranges).
- Total hop oils and oil composition are commonly specified for aroma planning; Centennial is described as citrus-floral in USDA cultivar documentation.
- Moisture content and oxidation/stability indicators (e.g., hop storage stability concepts) are monitored because hop aroma and bittering potential degrade with oxygen and heat.
Grades- Type 90 (non-enriched) pellets and Type 45 (lupulin-enriched) pellets are widely used hop-product classes; most Centennial pellets supplied for brewing are Type 90 unless explicitly sold as enriched products.
Packaging- Oxygen-barrier foil packs (often vacuum sealed) with inert-gas flushing are common for hop pellets to slow oxidation.
- Bulk pack sizes (e.g., multi-kilogram foil packs in cartons) are common in commercial brewing supply chains.
ProcessingPellet format improves homogeneity and handling versus whole cones and is widely used for kettle additions, whirlpool additions, and dry hopping (depending on brewery practice).
Supply Chain
Value Chain- Harvest hop cones -> kiln drying -> baling -> milling -> pelletizing (Type 90 typical) -> inert-gas/vacuum packaging -> cold storage -> export/import distribution -> brewery use
Demand Drivers- Brewing demand for citrus-floral American hop profiles associated with Centennial in hop-forward beer styles.
- Operational preference for pellet format due to dosing convenience, product homogeneity, and storage/transport efficiency relative to whole-cone hops.
Temperature- Cold storage is commonly recommended for hop pellets to reduce oxidation-driven loss of alpha acids and aroma compounds; room-temperature storage can materially degrade hop quality over time (cultivar stability notes exist in USDA documentation for Centennial).
Atmosphere Control- Inert-gas packaging and low-oxygen handling are widely used for hop pellets to slow degradation during storage and transit.
Shelf Life- Shelf-life and brewing performance are sensitive to oxygen exposure and temperature; storage stability at room temperature can be poor for Centennial per USDA cultivar documentation, supporting the commercial practice of cold-chain storage for pellets.
Risks
Supply Concentration HighCentennial is a U.S.-origin cultivar and commercial supply is closely tied to the U.S. hop system (Pacific Northwest). A localized production or processing disruption (weather shocks, wildfire smoke, water constraints, facility outages, or logistics disruption during the post-harvest processing window) can tighten availability for this specific variety and force substitution or reformulation in export markets.Use multi-origin or multi-variety recipes where feasible, secure forward contracts with defined substitute options, and maintain cold-stored safety inventory for critical brewing programs.
Climate MediumHeat, drought, and wildfire/smoke events in major hop regions can affect cone development, yields, and sensory quality, increasing year-to-year variability and contract fulfillment risk for aroma varieties.Monitor seasonal crop conditions, diversify procurement across growers/merchants, and consider sensory/analytical acceptance bands that allow controlled lot blending.
Quality Degradation MediumHop pellets can lose bittering potential and aroma through oxidation, especially when exposed to oxygen and higher temperatures; Centennial has documented sensitivity to room-temperature storage in USDA cultivar records, elevating the importance of packaging integrity and cold storage.Require low-oxygen packaging specs, verify packaging seals on receipt, and maintain cold-chain storage through distribution and brewery inventory rotation.
Regulatory Compliance MediumMarket access can depend on import documentation and conformity schemes (e.g., EU import conditions requiring an attestation of equivalence for hops and hop products), and on compliance with pesticide residue limits.Align supplier documentation to destination requirements, implement residue and contaminant testing plans, and maintain traceability to lot level.
Sustainability- Agricultural input intensity and plant-protection practices (pesticide use and residue compliance) are recurring sustainability and market-access themes for hops used in global beer supply chains.
- Water and heat stress risk in key hop-growing regions can pressure yields and quality, with implications for supply reliability and contracting performance.
- Energy use and packaging footprint associated with pelletization, inert-gas packaging, and cold storage are material contributors to lifecycle impacts for pellet hop products.
Labor & Social- Seasonal agricultural labor availability and compliance (including worker protections) is relevant for hop harvesting and processing in major hop origins.
- Worker health and safety risks (notably around agrochemical handling and processing operations) are a social compliance theme for hop supply chains.
FAQ
What does “Type 90” mean for hop pellets like Centennial?Type 90 (T90) generally refers to standard hop pellets where about 90 kg of pellets are produced from 100 kg of raw hops, with the pellet composition remaining close to the original hop material. Industry references such as hop processors and merchants describe Type 90 as the non-enriched, widely used pellet format for brewhouse and dry-hopping applications.
Why are Centennial hop pellets commonly kept in cold storage?Hop pellets lose bittering potential and aroma when exposed to oxygen and higher temperatures, so cold storage and low-oxygen packaging are used to slow degradation. The USDA cultivar documentation for Centennial notes poor room-temperature storage stability, which supports the commercial practice of cold storage for pellet hop products.
Where does Centennial hop primarily come from in global trade?Centennial is a U.S.-origin hop cultivar from the USDA hop breeding program in Washington State, and commercial supply is most closely associated with the U.S. hop production system centered in Washington, Oregon, and Idaho. For buyers, this means availability and pricing are highly sensitive to U.S. crop outcomes and post-harvest processing capacity.
