Confessions of a Yeast Abuser

denny's picture

I have a confession to make...I am a yeast abuser. And I have been for years. Yes, I know all the "rules" and try to follow them, but sometimes I fail and resort to....yeast abuse. Recently I brewed a batch of my Rye IPA recipe on my Zymatic. Looking in the fridge, I saw some WY1450 with a date of June 26, 2015....10 months old. I thought "I could make a starter with that", but then I thought "Damn, that would take effort".

Episode 10 - You've Got Questions, We've got "Answers"

drew's picture

It's Episode 10 and it's finally time to see if we're as smart as we say we are. We discuss the listener response to our Session Beer efforts and promise to post a kickass list of session beer recipes. (Link below) We run off to the pub and discuss the recently concluded Pacific Northwest Homebrewers Conference and the lameness of "pink washing" and silly sexism.

Session Beer Day Recipe Bonanza - 14+ Recipes For You To Brew

drew's picture

Inspired by Lew Bryson's appearance in Episode 9 of the podcast, we decided if we were going to talk session beers and promote the idea of session beers, then maybe we oughta give you some recipes. So we reached out to a bunch of folks, both known and not so known, and asked "hey, give us your favorite Session Beer recipe!"

Have You Seen Ester?

I remember back to when I brewed my first batch of beer. It seems like yesterday; however, over two decades have elapsed since that faithful day. Much in the world of home brewing has improved dramatically during the last twenty years. An improvement that comes readily to mind is ingredient quality. Those of us who were participating in the hobby during the first home brewing boom can attest to having to work with hops that were often brown and malt that was past its prime. Small-scale brewers used to receive macro brewer cast-offs, and home brewers received the macro cast-offs that small-scale brewers rejected. While poor ingredient quality and selection are a thing of the past, there are areas of home brewing that have changed very little in the last twenty years. One such area is an understanding of fermentation byproducts. We have transitioned from a hobby with an incomplete understanding of fermentation byproducts that fermented at room temperature to a hobby that uses temperature-controlled fermentation chambers to mask our incomplete understanding of fermentation byproducts. The topics covered in this blog entry are fermentation byproducts and the role that they play in beer flavor.

Olive Oil vs. No Aeration

drew's picture

In September 2005, Grady Hull of New Belgium, developed a new technique of strengthening yeast in storage by adding olive oil. The theory was that yeast use oxygen to synthesize sterols to build stronger, better cell walls so instead of introducing beer staling oxygen to the mix - why not add a tiny drop of cheap olive oil, a source of sterols, directly and let the yeast do it's thing. Cheap olive oil vs. expensive aeration equipment

Subject: 

Does the addition of olive oil to a fermenter replicate the organoleptic impact of aeration on a the beer versus doing no aeration at all?

Episode 7 - A New Faction

In Episode 7 - Denny and Drew take a spin through listener reactions to the first experiment results unleashed online and in the podcast. Then it's off to the pub where they discuss the rise of homebrewing around the globe (focused on an article about Indian homebrewers), Denny wields the eraser of correction about the beers he tried from Barrel of Monks and Drew talks up Lew Bryson's Session Beer Day project.

Comparing First Wort Hopping to 60 minute Bittering Additions

drew's picture

Some studies have shown that First Wort Hopping (FWH) actually produces about 10 percent more measureable IBUs than a 60-minute addition, but it tastes less bitter. Is this true? Should we all be First Wort Hopping our beers. Wait a tick - what's First Wort Hopping? Simple - it's a process of adding a hop addition into the boil kettle immediately as you begin running off from the mash tun. The hops stay in and you boil them for the full time of the boil.

Subject: 

How does the bittering from FWH compare to the bittering from a 60-minute addition?

Writeup: Yeast Comparison of the "same" strain - Wyeast 1056 / WLP001

drew's picture

The Subjects Under Question (courtesy Bob) For our very first experiment we asked our IGORs to tackle a fairly simple experiment. Can tasters detect a difference between the same wort fermented with the classics Wyeast 1056 American Ale (nee Chico) and White Labs WLP001 California Ale? See the link above for the full writeup on the parameters of the experiment.

Episode 6 - What's Your Faction?

In Episode 6 - Denny and Drew look to even more listener feedback. In the pub we promulgate a public service announcement near and dear to Denny's heart, investigate rumors of nefarious hop dealings and reminisce about Denny's time in the big snowy territory of Vail. And then we go to the lab where we discuss the first ever results delivered by our IGOR crew. Is there a discernable difference between Wyeast 1056 and WLP001?

Episode 5 - Whirlpooling Around the Yeast Bay

drew's picture

In Episode 5 - Denny and Drew look back at the Brew Year's Resolutions where we've had a bunch of feedback from listeners. We talk in the pub about the latest in acquisitions with the sweet spicy addition of hypocrisy - throw in a little competition and Denny's soon to be appearance in Vail. After that we return to the lab to present our second experiment.

Hop Whirlpool - Does steeping at lower temperature improve final hop character?

drew's picture

If you're gunning for big hop aroma to your beer without the grassiness of dry hopping, traditional practice calls for a large dose of hops after the boil has concluded. These "whirlpool" hops, so called because properly the wort is cycled to create a whirlpool, are thought to give a big dose of aromatic hop oils that aren't volatilized by the high heat and action of a boil.

Subject: 

Does steeping at a reduced whirlpool temperature (~120F) provide more robust hop character from the same hop charge compared to more traditional brewing practices of adding whirlpool hops just post boil

The Dangers of Brewing with Grapefruit

TLDR - BIG TAKEAWAY - A quick plea to brewers everywhere - for the love of all of everyone - label if your beer uses grapefruit in it. Turns out there's a chance of it causing some nasty side effects. (Actually for that matter - be kind to everyone and label your beers with anything outside the core four.) Edited to add - Taking feedback from various parts of the community and adjusting language to be less hyperbolic Not that long ago, grapefruit was an American breakfast staple.

Episode 4 - Brew Year's Resolutions (A Meditation on Possible Failure) and the Best Amendment

drew's picture

In Episode 4 - Denny and Drew reflect on the feedback we received about our discussion of the decline of homebrewing before we head to the Pub to talk about socially conscious brewing projects like Lady Justice Brewing in Denver and we talk about the Brew Tube community and how they're coming together after a loss.

Episode 3 - Over a Barrel, Experimentally

drew's picture

PROFANITY WARNING - There are a few unbleeped blue utterances in this podcast - if you're sensitive to blueness, please wear headphones! In Episode 3 - Denny and Drew start out in the Pub talking about a distressing topic - the possible decline of homebrewing, the causes and what all of us can do about it. Then we get into the real meat of our whole show as we head into the Experimental Brewing Labs in Casa Verde - it's experimentation time!
