A friendly place for friends who drink

[TobyG]

Since I'm home sick wearing a Brulosohphy shirt, I figured I'd go read. These were not conducted by Marshall, but by other contributors.
xBmt 1: Shaken vs No oxygenation - No significant difference achieved but not high gravity beer (it was an IPA) and not as many participants since him and family and friends drank too much and one keg blew. Only 1 person picked right.
xBmt 2: Shaken vs Oxygenated - No significant difference achieved. Only 9/21 could tell a difference.
xBmt 3: Oxygenated vs No oxygenation - Close to a significant difference, but not quite. High gravity beer needed 17 correct to achieve significance and hit 16.

TL;DR: You want to use either shaking or oxygenation, but not enough data to really say if one is reliably better than the other.

Not nessecarily so

http://braukaiser.com/wiki/index.ph...ity_and_efficiency_in_single_infusion_mashing

The TL,Dr version is thin mashes = better efficiency without any increase in fermentability and/or attenuation.

That's pretty interesting to hear, thanks for that link. Like he mentioned, most home brewing literature that speaks about mashing says that it does have an effect to do the maltose production variations.

By better.I mean slightly cleaner. Not something I would stress about. I made a lot of good brews without the O2 set up.

Lag time does not bother me, so that is not it. I never really pay attention to it anyway. I am not talking a huge drop in fg just a couple of points. more noticable in high gravity brews.

They got to 8 ppm by filling the headspace with O2 and then shaking. I just re-read the link. It conflicts with the amout of disolved O2 that Whitelabs says you can get.

Again not something that would say that everyone had to rush out and get.

 

[DisturbdChemist]

That's exactly right. I have never actually tried the multiple rounds of oxygen route though. It would be interesting to see a side by side experiment on two beers to test it. Even on these milds everyone is brewing, its impossible to get the correct amount of oxygen in without a stone.

New Belgium and others used olive oil to provide enough aeration to the wort.

Water. About to cool down a test.

Late lunch/snack time.

I think I could eat my weight in jalapeño stuffed olives.
Wife went to have lunch with our daughter today at a brew pub. I get a text saying she's bringing home baby. She gets me.

I figure I'll weigh in on the discussion. If anyone cares or is reading this. I'm a shaker. I siphon out of the BK holding the tubing toward the top of the fermenter so that it splashes as it fills up, usually creating foam. Then after I pitch an adequate amount of yeast, I shake the crap out of it. Usually have visible activity before I go to bed that night if in pitch mid-late afternoon. Never had a problem with lag time except the time I didn't pitch enough yeast. And under-attenuation has never been an issue.
But according to everyone here, I don't brew, so what do I know.

Wow, I had to look that up. Pretty interesting stuff. The few articles I read even mention the advantage of olive oil over oxygen in long term storage and not becoming stale like regular beer. I think I'll stick to oxygen unless the apocalypse happens and I have a bunch of oil sitting around.

I read about it a while ago, and the ideal amount of olive oil was so tiny it didn't make any sense on the homebrew level. Maybe for New Belgium brewing huge batches and using 1 drop of oil.

I tested out a venturi setup with a Tee I had on hand that worked pretty well and frothy, but it's definitely too large. Need to bottleneck beforehand to increase the velocity, would be nice to get it up to 12fps so it's turbulent.

That looks like a good solution.

Yeah I seem to recall it being less than a pinhead's worth. I'll probably try it out sometime, just dunk a toothpick in oil and then the beer or something. I'm not too worried about what a drop of oil will do to head retention. Or conversely maybe that's the trick to making a sweet huge stout. Love the ones that have such an oily mouthfeel it coats your tongue for minutes afterwards. "Secret ingredients: 10% flaked rye, three drops EVOO)

I'm glad this thread has reverted back to science once again.

Thanks Psy!

What happened? I blacked out.

 

[BigPerm]

I heard in an interview with Jamil Zainasheff that, especially on a high gravity like a RIS, without a stone its almost impossible to get enough O2 in solution. He recommended for a RIS to hit it with O2 2-4 times in the first 12 hours. My plan is once before pitching and again a few hours later.

Since this conversation seemed to be calling my name, we brewed a RIS Saturday. OG - 1.106. Primary fermentation was with a 2month old yeast cake of WY3787, fed 4 days prior. Pure O2 for about 60-90 seconds per fermenter (split 3 ways. 3787 will make you pay...). It still took about a full 24 hours to get going, but was sitting at 63 ambient. Moved to 70, and here we are 36 hours later.

Looks like Brulosophy did a series of experiments earlier this year. Someone should go read all 3 and summarize them for the benefit of the thread

xBmt #1 - shaken vs non-shaken IPA. OG = 1.070. Both finished at 1.016. 1 carboy was shaken for around 3 min before adding yeast. No noticeable difference it time to krausen. Only 1 of 7 people guessed the shaken one correctly.

xBmt #2 - O2 vs shaken. OG = 1.053. one keg shaken for 90 second. FG was 'slightly different' but exact numbers not given. The other was given pure O2 for 2 minutes (.5 micron). No difference in taste and not statistically significant number of people could tell the difference.

xBmt #3 - O2 vs nothing. Barleywine OG 1.096. 5 minutes of O2 with .5 micron stone vs nothing for the other. Fermentation started around the same for both. O2 batch went longer. Nothing batch FG = 1.026. O2 batch FG = 1.020. 16 of 36 selected the O2 batch. The author said he thought the O2 batch tasted cleaner. The nothing batch had slight yeast off flavor.

Your welcome.
My other option was to actually work...

I think they used 500mL per 100bbl batch. In homebrew scale it does not make since. Maybe just a huge abv beer

YOU ALL SHOULD BE BURNED FOR WITCH CRAFT!
Everybody knows that beer ferments only by the grace of the Lord.

Honestly, these lengthy diversions make this thread way better than the other. Lot of collective experience here.

Off topic. Thanks Ryan!

I dunno, before this post there was a long time of no pictures of of beers being drunk. I'm reporting everyone, myself included.

Yeah those and the root beer one are just way too sweet. Nasty. But I'm not a diabeetus soda drinker.

I've cut way back on soft drinks in the last few years, down to 1 or 2 a week. Of course, that consumption was taken up by beer, so I guess it's a wash.

Please tell me you cut the shiiiit out of your thumb while cobbling that together.

Also, packing tape band aid? Winning.

I liked it. It's pretty approachable. Light tartness, bit of funk, malty base. I don't know how it's changed with time, but I like it.

Good to hear, I just wasn't a fan last couple times I had one. I'll throw another in the fridge for science. Cheers!

Yea, I still have 2 root beers out of a 6 and I gave 2 away

Dragon Paw Berliner from Hourglass. Is $30 for a pitcher of Stille Nacht a fair price?
