Total Resin Extract

Appearance

Dark green in color, TRE is a thick syrup/paste.

Flavor

The flavor and especially the bitter characteristics of the original hops are completely retained. Early additions of TRE during wort boiling mainly serve to impart bitterness.

Utilization

If TRE is boiled for at least 50 minutes, utilization within the range of 30 - 40 % 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)
• Drum 200 kg (US / DE)

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

Dosage

Kettle additions of TRE are based on the concentration of bitter substances (CBV), an estimated or known utilization and the desired intensity of bitterness in the beer.

Application

Pre-warming cans of TRE 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 TRE 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 (50 °F).

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.

Safety

Ensure good ventilation of the workplace and wear personal protective equipment. Avoid contact with eyes and skin. Do not inhale vapors or dusts. For full safety information, please refer to the relevant Hopsteiner® safety data sheet.

International approved methods listed in commitees such as ASBC or Analytica-EBC using current standards are applied.

Product analytics

• Analytica EBC 7.6 (LCV)
• ASBC Hops-8 (II) (LCV)
• Analytica-EBC 7.8 (HPLC)
• ASBC Hops-16 (HPLC)

The product is normally dosed according to its Conductometric Bitter Value (CBV) as this value better represents its bitterness potential.

Note: CBV = LCV (EBC 7.6) + 50 % of iso-alpha acids (EBC 7.8)

• Analytica-EBC 7.10 (Distillation)
• ASBC Hops-13 (Distillation)
