CO2 hop extract products are produced from soft, hop pellets by supercritical CO2 extraction. CO2 hop extract is the pure resin extract of hops containing alpha acids, beta acids, and hop oils, and is designed to deliver clean bitterness and hop aroma in the kettle boil. CO2 hop extract typically contains 45-65% alpha acid, 15-35% beta acid and 5-15% oil. CO2 hop extract can be produced from any hop variety but is typically available in several high alpha varieties. Informational summaries for these hop varieties are available at yakimachief.com.
Application:
CO2 hop extract is primarily used as a kettle hop ingredient to provide clean bitterness and hop character to beer. It also improves physical stability and contributes to consistency.
The aroma of the CO2 hop extract is variety specific. Perception of hoppy character and various related notes in beer are also variety specific in some instances and will depend on the quantity of extract added and the time of addition during kettle boil. CO2 hop extract is primarily utilized in bittering applications with high alpha varieties so aroma is limited.
CO2 hop extract is primarily used as a kettle hop ingredient to provide clean bitterness and hop character to beer. It also improves physical stability and contributes to consistency. Traditionally, kettle hopping with extract will also lead to improved trub formation and improved antimicrobial and anti-foaming properties. Add CO2 hop extract in wort early during kettle boil for bitterness and late during kettle boil for aroma. Based on quantity required, CO2 hop extract packaged in custom tins can be directly flushed with hot wort in the brew kettle or in specific by-pass dosing systems or heated to 122°F – 140°F (50°C – 60°C) and poured directly into the kettle. Heating temperature and time may depend on variety. Addition rates depend on the alpha concentration of the extract.
1. PACKAGING
Standard packaging is available in 55-gallon steel drums, or in 0.5 kg, 1 kg, 2 kg, 3 kg and 4 kg tins containing 200 g to 2.4 kg alpha acids.
2. STORAGE
Uniformity of CO2 hop extract can be achieved with lot sizes up to 10,000 kg. The inner coating of metal tins and drums are approved by the FDA for use with food products and meet the requirements of Food Additive Regulation 21 CFR 175.300. Tins are marked with 16-9000 food grade ink. CO2 hop extract may be stored at room temperature, preferably between 41°F and 77°F (5°C and 25°C) or in cold storage conditions, preferably between 30°F and 41°F (-1°C and 5°C). CO2 hop extract will remain stable in closed containers for three (3) years when stored at room temperature and five (5) years when stored in cold storage.
