    GMO yeast producing hop oils without the hops? I'm all for it! Some, we'll just say "less than informed folks", might not be as excited.

    Really interesting news. Not surprised a scientist decided to tackle modifying unicellular yeast to see if they could do more things with it. Will be a different world when brewers are double dry yeasting at various gravities to get the hop flavors we want :wink:

    This will get banned quickly in Europe and have all the free range ethical omnivores up in arms in the USA. Soon, we'll see an organization called PETY formed.

    I think they just unlocked the secret of Romulan Ale.

    Yeast can do all kinds of neat things. Making lactic acid is one of them, but making terpenoids is even more so.

    That's cool and all but how does it TASTE? I remain highly skeptical until I know that key bit of information.

    If this becomes commercially viable I can see it's use by home brewers who simply want to make a decent house beer.

    I haven't seen him around here in a long time, but I would be really interested in what @Peter_Wolfe thinks of this.

    It's all fun and games until the power goes out on the security fences and they rampage out of the paddocks.

    It'll be an interesting time when you can combine hop and yeast blends for flavor and bitterness.

    The answer is in the post you are responding to

    ".....In a double-blind taste test of two batches of the final hop-free pale ale compared to a regularly brewed pale ale, tasters found the hop-free beer to have more of the style’s characteristically bitter flavors....."

    I have to assume @Hayden34 sas really referring to the enjoyablensss.

    For example, you can create many ind tastes where you ask people whether both of these cakes (one with stevia and one with sugar) have that sweetness we associate with cake. That does not answer whether it is "as good." Just because it is substitutable does not mean it tastes the same. I literally cannot think of anything that I can substitute that tastes "exactly the same." (Per the example above, I hate Stevia.)

    Yes, but deep into the future and space Burton water will be available from hydrogen, oxygen, and Druidic incantations. It is written. Real ale is safe for almost eternity.

    Apparently, a biochemist at UC-Berkeley has done some bio-engineering (read the article for a more detailed description of what, exactly, he's doing) that effectively has created a yeast strain that imparts the flavor and aroma of hops--specifically Cascade.

    I admit that my initial reaction was skepticism, *but* apparently they worked with Lagunitas to convene a blind tasting with over 40 people and the beer with genetically engineered yeast and no hops performed well against traditionally-hopped beers.

    Obviously, it's a LOOOOOOOOONG ways away from having a meaningful impact in the actual commercial beer market. Can it be done with other hop varietals besides Cascade? Is it scalable? Can it be done at a price point that makes it a viable alternative to actual hops? Are brewers who have infrastructure and processes aligned to make beer with hops going to want to move in another direction? Would there be a different set of implications for Big Beer vs. smaller independent brewpubs and taproom size breweries?

    And that's before we get into the uphill marketing battle of getting beer enthusiasts to buy into a beer without hops tasting the same as or better than the traditional IPAs they are accustomed to. It's one thing to convince people doing a blind taste test--most consumers aren't going to be conducting blind tastings, and there are some who won't even entertain the idea enough to buy a bottle/six pack in the first place.

    Here's another article that summarizes the Times article, in case you have hit your limit on free articles at NYT:

    The NYT article was an interesting read with much discussion about hop flavor. How was bitterness achieved in the hop-less beer?

    Cheers!

    P.S. The answer to my question was in another article:

    “They then asked Charles Bamforth, a malting and brewing authority at UC Davis, to brew a beer from three of the most promising strains, using hops only in the initial stage of brewing – the wort – to get the bitterness without the hoppy flavor. Hop flavor was supplied only by the new yeast strains. Bamforth also brewed a beer with standard yeast and hops, and asked a former student, Lagunitas’s Donaldson, to conduct a blind comparison taste test with 27 brewery employees.”

    Why not just use non gmo real hops?

    Of course, unless they change the TTB rules (or somehow get the yeast recognized as a "hop product"), brewers would have to have their labels approved by the FDA, a different Federal bureaucracy than the one they regularly work under, and whose labeling requirements are different and more complicated than the TTB's.

    But do the regulations say anything about the quantity of hops? Would one "hop" per batch suffice? :wink:

    I'm still around, lurking. Just very busy with work and newborn kids.

    I met Charles Denby, the individual whose lab is doing all the work at Berkeley, at the World Brewing Congress in 2016. He told me about the project and I told him I was intrigued and would be happy to help run trials with him. I can't say a ton about it yet because it's early on, but I can say I started running pilot trials with his yeast earlier this year. I've made six brews to date using Dr. Denby's modified strains.

    First - the article is all kinds of stupid. The yeast strains have nothing to do with bitterness whatsoever. The strains are modified to include genes from basil and mint plants so that they can manufacture terpenes (aroma flavor compounds) identical to those already produced in hop trichomes. Bitter acid synthesis is unaltered.

    I can say with some certainty that they're absolutely not a total replacement for hops, but they might be a good way to augment or change and add to the overall hop flavor in a beer. I'll know a lot more in a couple months, but early trials seem promising.

    Personal Partially Related Rant (feel free to stop reading here):
    I'll add this about GMO, because I know people always want to focus on that. If you're someone who considers themselves a supporter of sustainability, clean energy, and a clean environment (which I personally am), you should absolutely be an ardent and enthusiastic supporter of GMO technology. This doesn't mean that you need to support corporate ownership of it (everyone always wants to talk about Monsanto, which only distracts from the actual subject), but GMO itself is the only way we're going to feed the current and future population of the planet earth without permanently harming it and numerous other species. The alternative is dramatically reducing our population, and I don't foresee anyone volunteering to do that.

    My one concern would be that they have to use much more yeast than normal to get the flavor right. Not all people can tolerate a ton of yeast in their diets. I'd prefer good old hops myself. Cool to see scientists working on beer though.

    Your information is always great. I'm glad you are still around, but there are more important priorities than BA, clearly.
