Though phenolic character and diastatic ability frequently appear together in brewing strains, they are not really connected at a genetic level. Take a look at which strains are just phenolic, which are phenolic and diastatic, and which are just diastatic. You might be surprised.

NA and LA beer has made huge strides in quality and availability in recent years, but large hurdles remain for creating it safely. Are you set up to manage risk and create tasty beer without alcohol?

Get a better grip on diastatic yeast to improve your protection from a potentially devastating cross-contamination.

Media that gives a snapshot of actual diastatic activity covers gaps in current testing and adds more insight to diastatic cross-contamination screening. This is something new from Omega Yeast researchers.

Omega Yeast’s researchers tweaked standard LCSM so it alerts to the strains it had previously been missing. Just take a look at how standard LCSM and the optimized version perform differently. Scary!

There’s so much space for activities.

This improved recipe for LCSM, developed by Omega Yeast’s researchers, covers gaps you may not have been aware existed with standard commercial LCSM.

Omega Yeast’s R&D team gives phenolic strains’ fruity esters a tap take-over, making former Belgian and Hefeweizen strains into something clean and fruity, and a new tool for more modern styles.

Gram staining and catalase testing are lab tools that when considered together help you assess what threat a contaminant might pose. It’s not what each test tests for that’s the point really, it’s more about identifying characteristics that differentiate groups of bacteria, so you know what you’re likely to be dealing with.

There’s more than one way to get lactic acidity in beer. Let’s get brighter about Lactobacillus.

Omega Yeast’s researchers can make diastatic strains non-diastatic. That means there are now a couple of ways to avoid the risks those strains posed, while keeping more of what you love about saison.

When yeast leaves some of its discarded things around, it tends to pick up after itself (well, with a little encouragement). Then again, sometimes it just has too much on its plate. That’s where ALDC comes in. ALDC is like the Marie Kondo of diacetyl. It gets rid of what will later become a mess before it even starts. And it can be even more effective when yeast are enabled to produce it.

One especially sweet, thick IPA style and one extremely dry, thin one may have something good together when they combine signature elements.

You might be someone who avoids a bloated pack, but once it’s discounted, maybe it starts to look pretty good. Should you go for it? Why are some of us even suspicious of a swollen pack in the first place?

Incisive new strains can deliver something novel, or they can make something that already exists even better. In this series of articles, we look at modern strains through the lens of ​‘new’ or ​‘improved,’ deliver helpful takes on some yeast fundamentals (like esters, attenuation, and more), and finish with some juicy research: a new technology giving greater command of clarity and haze. Top Crop’s annual newsprint edition is available online or in print.

Using technique to improve clarity in your beers.

A more perfect system never existed for testing haze and flavor, thanks to the discovery of yeast’s hazy gene. In two brews differing only by the presence or absence of yeast-determined haze, blind tasters couldn’t pinpoint which was which. That begs the question, does haze contribute to flavor?

Since healthy yeast’s role in stable haze formation is a new concept, a lot of mysterious haze outcomes experienced by brewers can be helped via understanding yeast.

Yeast-derived haze can be substantial. How much has a lot to do with interaction with dry hopping. Here, see the surprising clarifying effect of an early-fermentation dry hop in a double dry hop scenario.
