Hops

Hops suppliers and sourcing guide

Hops are the female cones (strobiles) of Humulus lupulus, a climbing plant grown mainly in the US Pacific Northwest, Germany and the Czech Republic. The cones are kiln dried and sold whole, pelletized, or as extracts made with carbon dioxide or ethanol. Brewing buys most hops by variety and alpha-acid content; supplement and beverage makers use dried cone powder or extracts, sometimes standardized to bitter acids or xanthohumol.

Forms and grades of hops

Suppliers sell different products under the same name. Specify the one you need.

  • Whole dried cones

    Kiln-dried strobiles, baled and sold by variety and crop year.

  • Pellets

    Milled cones pressed into pellets (type 90 or concentrated type 45 lupulin) and packed under inert gas.

  • CO2 extract

    Resin extract made with supercritical or liquid carbon dioxide, sold by alpha-acid content.

  • Powder or dry extract

    Milled cones or ethanol or water extract dried to a powder for capsules and drinks, sometimes standardized to xanthohumol or bitter acids by HPLC.

  • Modified hop extracts

    Isomerized or reduced extracts used in brewing for bitterness and light stability, made under specific regulatory conditions.

What to check on the COA

Compare each result with your own specification when the lot arrives.

Alpha and beta acids
Alpha acids and beta acids by HPLC (ASBC or EBC methods) or by conductometric titration, the main commercial spec for brewing hops.
Hop oil content
Total essential oil by steam distillation, reported in mL per 100 g.
Marker assay (HPLC)
Xanthohumol or other markers for supplement-grade extracts, with the method named on the COA.
Heavy metals
Lead, arsenic, cadmium and mercury, usually by ICP-MS, checked against the buyer's limits and Prop 65 exposure targets where relevant.
Pesticide residues
Multi-residue screen, required for organic claims and commonly requested for conventional material.
Residual solvents
For extracts made with ethanol or other solvents, residual solvent levels against USP <467> or the buyer's spec.

Storage, lots and expiry

Storage and shelf life

Hops lose alpha acids and oil and develop off odors through oxidation, so keep cones and pellets cold (often at or below 0 C) in oxygen-barrier packaging flushed with nitrogen. Extracts and powders should be sealed, refrigerated where the supplier requires it and protected from light. Shelf life follows the supplier's spec, with alpha acids or the marker assay rechecked at retest.

Lots and expiry dates

Alpha-acid, oil and xanthohumol content vary by variety, crop year and storage time, so always buy and adjust on the lot COA. Record the variety, crop year, supplier lot and packaging date, and use oldest stock first.

Frequently asked questions

What forms of hops can brands buy?

Common forms include whole dried cones, pellets, cO2 extract, powder or dry extract and modified hop extracts. Ask each supplier for the specification sheet of the exact grade they quote.

What should the COA for hops include?

Expect alpha and beta acids, hop oil content, marker assay (HPLC), heavy metals, pesticide residues and residual solvents, each with its method, specification and result for that lot.

How should hops be stored?

Hops lose alpha acids and oil and develop off odors through oxidation, so keep cones and pellets cold (often at or below 0 C) in oxygen-barrier packaging flushed with nitrogen. Extracts and powders should be sealed, refrigerated where the supplier requires it and protected from light. Shelf life follows the supplier's spec, with alpha acids or the marker assay rechecked at retest.

What is the regulatory status of hops?

21 CFR 182.20 lists hops (Humulus lupulus L.) among essential oils, oleoresins (solvent-free) and natural extractives generally recognized as safe for their intended use. 21 CFR 172.560 permits modified hop extract as a food additive used as a flavoring agent in the brewing of beer, made by listed processes. Health Canada's Hops natural health product monograph lists Humulus lupulus with the dried strobile as the source part.
