OIL RICH CO2 EXTRACT / CO2 HOP OIL EMULSION
Purpose The convenient and consistent alternative to ‘dry hopping’ for the provision of hop aroma and flavour to beer post fermentation.
Composition Emulsion made from oil rich CO2 extract and containing the essential oil of hop and soft resins in an aqueous emulsion with food grade emulsifiers. The oil content is standardised to 2,500 ppm (0.25%) by volume, while the soft resin content is dependent upon variety. The emulsions convey the characteristic aroma and flavour of the hops from which they are prepared. Further information on the characteristics of individual hop varieties, please see the Hop Variety Data Sheets on the Barth Haas Group Website:
Datasheet.
Use The addition of 40 to 80 ml of emulsion per hectolitre of beer corresponds to 1 or 2 ppm of oil. The emulsion is preferably metered into the beer stream before or after conditioning but before final filtration. Alternatively, the emulsion may be added directly to the cask during filling and before the addition of finings.
Packaging Normally available from Botanix in sterile 22.5, 40 or 50 litre stainless steel kegs or 25 litre polydrums. Smaller packages are available.
Storage Store in unopened containers. For prolonged storage (up to 6 months) we recommend cold storage at 3o – 6o C. Partly used containers should not be stored owing to the risk that sterility may be compromised.
