Traditionally, barley is used as the raw material for the production of beer. Today, breakthrough technology is making brewing more diverse than ever before with the use of enzymes. Enzymes are needed to digest cell walls, release amino acids, and breakdown starch into fermentable sugars.

Ondea® Pro is a multi-enzyme blend formulated to secure efficient viscosity, turbidity reduction, protein degradation, and controlled attenuation. With 6 different enzyme activities, the brewing possibilities are unlimited with the use of Ondea® Pro. Ondea® Pro can be used to take the guesswork out of your brewing, whether you would like to brew traditionally to improve your brewing process, use high adjuncts, brew a gluten free beer, or brew with raw barley or a new raw material altogether to cut costs and/or create new flavors. The horizon is wide open when you choose to brew with Ondea® Pro!!!

Benefits of using Ondea® Pro:
  • Higher extract yield
  • Efficient wort and beer filtration
  • Control of FAN (free amino nitrogen) and fermentability
  • Improve foam stability and body
  • High adjunct decoction is possible
  • High Gravity Brewing with up to 26°P (first wort) is possible
  • Production of high-quality beer
  • Enables the use of unmalted barley
  • Flexible sourcing of raw materials

What other people say about Ondea® Pro in articles

"In summary, this investigation demonstrates that the Ondea® Pro barley brewing system is capable of efficiently producing high quality wort, in most respects comparable to traditional malt brewing."

Article in Journal of the American Society of Brewing Chemists · January 2014, The influence of malt quality on malt brewing and barley quality on barley brewing with ondea pro, compared by small-scale analysis

"Ondea® Pro and malt, resulted in higher extract levels than were observed for reference mashing, using either 100% malt reference or 100% barley reference and Ondea® Pro enzymes. Synergistic mashing effects between barley, Ondea® Pro and malt were observed for mash quality and efficiency parameters, particularly wort fermentability."

Published online in Wiley Online Library · 27 April 2016, Comparison of the impact on the performance of small-scale mashing with different proportions of unmalted barley, Ondea Pro®, malt and rice

What brewers are saying

"Rice has limited enzymes, recently I used Ondeo® Pro in my experimental brewery, I have seen drastic increase in extract yield, efficiency of my wort and beer filtration."

Dosing Range

Recommended Dosing Parameters:
0.55g – 1g/lb of Grist/Barley
0.73g - 1.46g/lb of Grist for Gluten Free Brewing
(Dosage depends on malt quality, adjunct ratio, and type of raw material)
Dose can be calculated to be added by volume.
Ondea® Pro Density: 1.21 g/ml
(Eg: 100g / 1.21g/ml = 82.7mL)

Dosing instructions

After determining your dose from above, Ondea® Pro should be added during Mash-In, starting when around one-third of the grist has been loaded into the mash tun.


Recommended storage: 0-10 °C (32-50 °F) Packaging must be kept intact, dry, and away from sunlight. Please follow the recommendations and use the product before the best-before date to avoid the need for a higher dosage. Best before: You will find the best-before date in the certificate of analysis or on the product label. The product gives optimal performance when stored as recommended and used prior to the best-before date.


Can you make a high quality beer with barley?

Brewers and independent taste panels recognize that barley beer made with Ondea® Pro have similar scores as normal high quality beer, making it suitable for blending with conventional beers. Demonstrating that most types of beers can be made based on Ondea® brewing.
An example with Ondea® pilsner demonstrates similar composition to a malt based pilsner with respect to Plato, alcohol, haze, pH, gravity, CO2, foam, RDF, etc. – and, most importantly, similar taste, as illustrated in below figure

Will Ondea® Pro change the flavor of my beer?

No, it does not change the flavor of the beer. In fact, the use of Ondea® Pro can potentially reduce off-flavors related to brewing with high amounts of barley.
Quotes from a Novozymes report "100% barley brewing - experiences with Novozymes Ondea® Pro"
"The first 100% barley beers were very light in taste in order to show that the Ondea brewing concept did not give rise to any off-flavours normally associated with traditional brewing with high barley inclusion. Any beer type can be made using Ondea brewing by simply exchanging the barley pilsner-type malt with raw barley and Ondea Pro."
"The success of the Ondea brewing concept is tightly linked to the question: ”Can you make good beer without malt?” Our experience, based on a busy year and more than 100 trials with Ondea Pro, gives rise to a clear and distinct YES in answer to this question. The quality of the 100% barley beer based on Ondea brewing has impressed the brewers. 'Surprisingly good' – 'tastes like normal beer' – 'no off-flavors' have been some of the most frequent comments we
have heard."

What is the delivery time?

Delivery time is 3-5 work days. All orders are shipped viavia UPS ground / UPS 3 Day select after processing. (whichever option is fastest) This option is used to minimize the time that the product is at ambient temperature in order to maintain product integrity.

How do I add Ondea® Pro?

Ondea® Pro is added during the mashing step. The enzyme is added after the mash tun is about 1/4 filled, but it does not need to be precise. The most important is that there are some liquid in the mash tun before you add Ondea® Pro, so the enzymes can be evenly distributed, and does not get stuck in the bottom.

When you pour Ondea® Pro into the mash tun, add the liquid slowly to get an even distribution.
