Description
Flex 2 kg – liquid hop extract for bittering
Flex from BarthHaas is a liquid, concentrated hop product made from pure hops and designed for bittering in breweries. It has 65% alpha acid, contains no solid material and is poured straight into the kettle at the start of the boil. Hop additions can be reduced considerably compared with pellets, and wort losses to vegetative material are almost eliminated.
Please note: This product is only available in Norway.
Features
- 65% alpha acid and 100% liquid
- Gives even, consistent bitterness
- Better alpha acid utilisation than pellets
- Little hop trub, higher yield and easier cleaning
- Used for bittering only, with little or no effect on hop aroma
How to use Flex
Add Flex to the kettle at the start of the boil. The alpha acids must be isomerised during the boil, just as with hops and pellets. The dose is calculated from the alpha acid content and the expected utilisation, which varies with plant and process. The density is close to 1 g/ml, so Flex can also be measured by volume.
If the product has been stored cold, oil may separate or the product may stratify. BarthHaas then recommends warming it to 30–35 °C and shaking or stirring until even before use.

Frequently asked questions about Flex
When should Flex be added?
At the start of the boil. The alpha acids must be boiled to convert them into iso-alpha acids, just as with pellets.
How much Flex do I need?
Calculate the dose from the 65% alpha acid and the expected utilisation, typically 25–35%. Actual utilisation varies with plant and process, so adjust according to your own measurements.
Should Flex be stored in the freezer?
No. BarthHaas recommends 13–24 °C. If the product is stored below 13 °C, oil may separate. Warm it to 30–35 °C and shake or stir before use.
How long does Flex keep?
Best within 36 months of production. An opened container can be used for up to 12 months if stored correctly and the product is no older than 36 months in total.
Does Flex add hop aroma?
No. Flex is designed for bittering and has little or no effect on aroma. Add aroma hops as usual late in the boil or for dry hopping.
