Save money on brewing - Achieve higher efficiency

Ultraflo® Max is a high-performing blend of β-glucanase and an arabinoxylanase that makes it possible to degrade both major cell wall components to ensure minimum viscosity and get the best wort separation and beer filtration. This enzyme blend will break down β-glucans and arabinoxylans into non-viscous polysaccharides and thus increasing extract run off of a more concentrated wort.

Benefits of using Ultraflo® Max:
  • Increase brew house efficiency and save on material costs
  • Consistent and high-speed wort filtration
  • Consistently increase brew house capacity
  • Avoid stuck mashes
  • Helps to reduce or eliminate production variations due to varying quality of raw materials
  • Maximize flexibility of mashing temperature profile
  • Helps to increase yields during High/Very High Gravity Brewing
  • Minimize brew house and beer filtration capacity cost

What other people say about Ultraflo® Max

"I've now used Maturex and Ultraflo in a few beers and I've been very impressed with the results. ... I've also brewed several times with Ultraflow max. It really helped with a high wheat beer (a gose) and now that I’ve got the dosage right, it helps pretty significantly with my New England IPAs (pretty wheat and oat heavy). So, cheers to you all at brewingwithenzymes, I’m a pretty happy brewer over here."

- Matt White, Owner & Brewer at Beachcrest Brewing Company
"First time using it today and we raised the efficiency by 6% which is awesome. I’m sure we’ll be ordering in the near future. We appreciate your help!"
- Bruno Simão and Alex Boettcher, Brewers at Arundel Cellars Brewing Company

"Ultraflo Max has exceeded all of our expectations. We have increased our average brew house efficiency from ~75% to ~91% since using this product. It has become a MUST have during brew days!"


"The enzyme is working excellent on our high gravity and high adjunct beers!

So far we have used it in a few higher gravity NE IPA's and have gotten 3-5% better efficiency. I think we can increase the number as we dial in the dosage rate. Our biggest success yet is a 19.5 Plato stout that we make a fair amount of this time of year. Its loaded with wheat and oats and is normally a huge pain to lauter and efficiency is all over the place/ inconsistent. With the Ultraflo we have been nailing our efficiencies and the ease/ time to lauter is saving us 30-60 minutes per batch, 3 batches per week."

-Andrew Blakeslee, Thomas Hooker Brewery


"It has increased our efficiency pretty noticeably and the runoff is much faster. I definitely want to try it on our recipes with a large amount of flaked and raw wheat."

-Ryan Bichon, Hoof Hearted Brewing


"We have been brewing with Ultraflo Max for about 2 months. This has been a life saver. Totally changes the viscosity of the wort and our pumps run so much smoother and because of that it also helps helps overall brew day efficiency. Thanks!"

-Jeffery Gattens, Four City Brewing Company


"We recently used both Ultraflo Max and Ceremix Flex in our seasonal hefeweizen, Banana Hammock. The combination of enzymes allowed us to use a locally grown wheat in place of a pre-gelatinized national brand. We saw an increase in body from the raw wheat, as well as a slight rise in overall mash efficiency while using the enzymes when compared to previous years."

-Brandon Ridings, Ono Brewing Company


"With Ultraflo® Max, we were able to eliminate human error and stuck mashes while saving time in our brew house."

-Charles Porter, Founder and Brewmaster, Little Beast Brewing

Dosing Instructions

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


Ultraflo® Max is a concentrated product and when used properly, cannot only provide you with the added benefits listed above, but it can save you money too. Below is a calculated Cost/BBL, based on an average brewing recipe, where Ultraflo® Max is dosed at the highest recommended dose based on Malt to achieve a final beer of ~6.5% ABV. These values do not take into account any added benefits, such as cost savings, and illustrates that this product will pay for itself.
1.1 lb (500g) at $49:
  • Cost/BBL = $0.44/bbl
  • Produces ~113 bbl of beer
2.2 lb (1000g) at $79:
  • Cost/BBL = $0.35/bbl
  • Produces ~227 bbl of beer
Disclaimer: These Cost/BBL values are calculated are based on a standard brewed beer and in no way represents actual values received from the use of this product. Actual values may differ from the calculated values displayed here and thus, are solely used for informational purposes only. Novozymes cannot guarantee the Cost/BBL values received using this product matching the values here, due to the variables associated with the brewing process and will have to be optimized for your individual brewing process.  

Optimum pH and Temperature

The optimal working conditions for the Ultraflo® Max:
Temperature range: 45°C - 70°C (113°F - 158°F)
pH range: 4.0–6.5.


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.

Dosing Range

Recommended Dosing Parameters:
Dose in weight: 0.090 gram/lb of grain
Dose in volume: 0.077 ml/lb grain
(Density of Ultraflo Max is 1.18 g/ml)
For 10 bbl brew using 600 lbs of grain you should dose in:
0.090g/lb * 600lbs = 54 grams of Ultraflo Max
(dose by volume: 54(g)/1.18(g/mL) = 45.76 mL)
Ultraflo® Max can be overdosed, resulting in a collapsed bed, which can reduce efficiency and lead to stuck mashes. We recommend a starting point of 0.090 gram/lbs of grain on your first batch, before you begin experimenting with dosing.
Dosage depends on malt quality, adjunct ratio, and type of raw material, so it may require some experimentation.
  • For high amount of adjunct you may increase the dose of Ultraflo® Max by 10-30 %.
  • If you have low quality malt you may need to increase the dose by 10-20 %.

Can I reduce my Mash or Lautering time using Ultraflo® Max?

A time reduction in mashing and/or lautering can possibly be achieved through optimizing the dose of your particular recipe and through monitoring the extraction rates during the mash. We have had customers decreasing their mashing time from 120 to 90 min, while keeping the same efficiency.

How does Ultraflo ®Max work in the mash?

Ultraflo® Max is made up of a β-glucanase and an arabinoxylanase, which makes it possible to degrade unmodified cell wall components of malted barley into non-viscous polysaccharides, resulting in a reduction of viscosity and thus significantly improving beer filtration. Ultraflo® Max provides far better performance than even the best well-modified malt, especially for beer filtration.  

Will Ultraflo® Max change the taste of my beer?

Ultraflo® Max will not change the flavor of your beer. The main benefit of using Ultraflo® Max is an increase in brewhouse efficiency. With this increase in efficiency, the mash extraction of sugars will be more concentrated and therefore will have to be optimized for your brewing process. It is recommended to measure your extraction rates during the mash in order to align your sugar profiles batch to batch and reduce your raw materials as needed to maintain the same extraction rates.

Are there concerns around using Ultraflo® Max?

Ultraflo® Max is known for its performance and added benefits, such as increased efficiency, and there should be no concerns when using Ultraflo® Max as long as the recommended dosing parameters are followed. The only concern for Ultraflo® Max around not following these recommendations is, it can be overdosed which can lead to a collapsed mash bed due to over degrading the cell walls in the malt and leading to poor circulation and possible stuck mashes.

What is the delivery time?

Delivery time is 4-5 work days. All orders are shipped via UPS ground / UPS 3 Day select after processing. (Whicever is fastest) This option is used to minimize the time that the product is at ambient temperature in order to maintain product integrity.  

We recommend that you order your product at least 14 days before you schedule your brewing with the enzyme, in case of delays

How do I add Ultraflo® Max?

Ultraflo® Max is added during the mashing step. The enzyme is added after the mash tun is about 1/3 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 Ultraflo® Max, so the enzymes can be evenly distributed, and does not get stuck in the bottom.

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


Will Ultraflo® Max affect the haze in NEIPAs?

No, Ultraflo® Max is a cellulase blend that works on breaking down beta-glucans and arabino-xylans and will not affect the proteins that contribute to the haze found in NEIPAs.

Will Ultraflo® Max affect fermentation/attenuation?

No, Ultraflo® Max works to breakdown unmodified cell walls to decrease wort viscosity and in doing so exposes more accessible sugars in the mash and can increase the specific gravity of the wort. Ultraflo® Max will not affect attenuation or cause the fermentation to finish dry.
