Does beta-glucanase affect the taste of Hazy IPA?

Hazy IPA is the most popular style of craft beer. It's praised for its soft mouthfeel, restrained bitterness and juicy aroma. Ultraflo Max can help you lauter faster and get better extraction. But will it affect the soft creamy mouthfeel of hazy IPA? We’ve made a simple experiment to find out.

What contributes to the taste of hazy IPA?

Hazy IPA is the most popular style of craft beer. It's praised for its soft mouthfeel, restrained bitterness and juicy aroma. Let's talk a bit about the soft mouthfeel of a hazy IPA. There are a few factors that contribute to it – dextrins, proteins, starches, glycerol, beta-glucans. Let's focus on beta-glucans. The rich source of this polysaccharide are oats, flake oats and malted oats as well, but to a lesser account. They are great in providing this silky creamy soft mouthfeel of hazy IPA, but they cause a lot of problems on the brewhouse with lautering, sparging and mash filtration. Solution to those problems is Ultraflo Max which is a mix of beta glucanase and arabinoxylanase. It will help you lauter faster, it will help you get better extraction. But will it affect the soft creamy mouthfeel of hazy IPA? Will it affect the haziness of hazy IPA? We've made a simple experiment to find out. 

What was the experiment about?

For this experiment I've used commercial double hazy IPA with 18 Plato starting gravity, 7.7% alcohol, 17% of grist of that beer were malted oats, flake oats and flake wheat. They should provide a bit of silky creamy soft mouthfeel to this beer. So, how the degradation of beta glucans which are considered to be important factor of the mouthfeel would affect this beer? To perform the experiment I use equivalent of 40 grams of Ultraflo Max per 100 kilograms of grist, which is double the recommended dose. I've placed the beers in water bed with temperature starting at 40 degrees Celsius and during two hours it was raised up to 70 degrees Celsius. So it was about the same time and temperatures as mashing. After the digestion, the beers were cooled and stored in the fridge for the experiment the next day. On the experiment day there were 31 tasters and they were experienced beer geeks, beer aficionados, homebrewers, professional brewers, so people who know their beer. Each of the participants were given three samples - two samples were digested beer, one was not digested. Their task was to find the odd one, the odd sample so it was a simple triangle test. Of those 31 participants only 11 were able to identify the unique sample and even some of those who guessed right admitted they were only guessing because they couldn't find any difference whatsoever. These results show us that there were no significant differences between the samples. 

What conclusions could we draw from this experiment? 

It seems that beta glucans are not that important factors in building the body of the beer, of building this soft juicy creamy silky whatever you call it mouthfeel of hazy IPA. There are other factors to consider when we are building recipes for hazy IPA – proteins, water chemistry, yeast, hops, glycerol production of the yeast during fermentation. There are a lot of factors, ethanol even, so beta glucans may not be as important as some of us may think. And what about the haziness of hazy IPA? Well, the main factor contributing to that are proteins, not beta glucans. So why use oats in hazy IPA? Well there are rich sources of proteins and they have this distinctive taste which we like in hazy soft juicy beers. You can use Ultraflo Max with a beer that has a high level of oats and you can have all the benefits of using oats without the obvious drawbacks. But don't just take my word for it, contact us, order a free sample of Ultraflo Max, test it for yourself and brew great beers. Cheers!
