CO₂-Hop Extract

Appearance

Golden green to amber in color, CO₂-Extract is a thick syrup (depending on the hop variety and extraction conditions).

Flavor

The flavor characteristics of the original hops are almost completely retained in CO₂-Extract. Early additions of CO₂-Extract during wort boiling mainly serve to impart bitterness.

Utilization

CO₂-Extract If CO₂-Extract is boiled for at least 50 minutes, utilization within the range of 32 - 38 % can be expected. Actual utilization will vary from brewery to brewery due to differences in equipment and process conditions.

Quality

All Hopsteiner® products are processed in facilities which fulfill internationally recognized quality standards. A monitoring system for residues is in place.

Our products are delivered in their respective recommended standard packaging. Alternatives may be possible upon customer request.
Standard packages of our processing plants in the USA (US) and Germany (DE) are:

• Cans 0.5 - 3.1 kg (DE)
• Cans 0.5 - 4.0 kg (US)
• Pail 4 - 20 kg (US)
• Drum 200 kg (US / DE)

Filling can be done as gramm extract or gramm alpha acids. The extract can be adjusted to a specific bitter content by admixing tannin extract or glucose syrup.

CO₂-Extract is typically added to the wort kettle as a complete or partial replacement for leaf hops or hop pellets.

Dosage

Kettle additions of CO₂-Extract are based on the concentration of alpha acids, an estimated or known utilization and the desired intensity of bitterness in the beer.

Application

Pre-warming cans of CO₂-Extract is not necessary. Suspending punctured cans in the boiling wort will ensure that all of the extract is completely flushed out into the kettle. If CO₂-Extract is added by means of automatic dosing units, it should be warmed to 45 °C (113 °F) and gently mixed to ensure perfect dosing.

Storage

The recommended storage temperature in the original unopened packaging is  < 10 °C.

Short-term, transport-related temperature deviations do not affect product quality.

Best Before Date

Under the recommended storage conditions, the shelf life from the date of production/ packaging is at least 8 years.
