There's Some Bad Info Going Around

[MrManifesto]

Many single cell organisms, especially ones that lack strong membranes (like yeast) have a defense mechanism where they build a layer of protein/lipid around themselves to help reduce the impact of cold/dryness (otherwise the internal water pressure would cause them to burst for instance). It should come as no surprise that it might use this structure to help propagate when more optimal conditions return. Most microbiology textbooks discuss this in some detail. You might want to start there.

Ahh ok, sounds like something I'll look into. Thanks for the response.

it's trehalose that is the yeast 'anti stress'. They purposely stress the yeast to produce this in the drying process to increase viability (but then they have to deal with the trehalase enzyme, but that's another topic and I'd hate to be an 'information nazi').

There are many mechanisms which yeast uses to survive less-than-optimal environments.

That being said, I do always keep trehalose and glycogen in mind. And so I think it's time to add more fuel to the fire...

I cold crash my starters, and decant/pitch the starter right out of the fridge, in order to take advantage of these reserves instead of letting the yeast *waste* it while warming up. That's right - when I pitch, the temperature of the yeast is just above freezing (and the temperature of the wort is just below my desired ferm temp.)

Now that you know how I pitch my yeast... who here ****ING HATES MY GUTS?

I do!!!! No, not really. Although I'm sure you've irritated somebody. I've never done it this way, just assuming that the quick temperature change would be bad for the yeast. I might be confusing yeast with tropical fish...

It's always cool to learn about different techniques, especially if the info comes from someone with some info on why it works. If I like it enough, I'll give it a shot (I'm going to try pitching cold yeast), if not, I move on. Easy as that. Sharing the info is the key.

 

[sudsmcgee]

Not me. I cold pitch starters as well.

 

[wildwest450]

Cold pitching is nothing new, I do it on every batch.

I just had a blast reading all ten pages of this mess.

Now you've hurt my feelings.

I work too much. Thank god for the comedy on this forum, I think I'd melt into the overstuffed chair in front of my desk without it.

 

[Jonathanquist]

I personally drop potassium sorbate tablets and I get fantastic results

 

[ReverseApacheMaster]

When I pitch yeast I just grab a handful of the liquid out of the wyeast pouch and toss it in like I'm shooting my load.

Skeet skeet skeet!

Pitching yeast onto wort is so, yesterday.

I always pitch my wort onto my yeast.

 

[johnnybrew]

Y'all need to take this to more of a literal meaning and actually pitch your yeast. I make a challenging game out of it and try to throw curve balls and sliders, but stay away from the spit balls for fear of infection.

 

[Hammy71]

What? No response today? C'mon gang. We can't let this meaningless thread die out!! I mean, surely you all are at least aerating your yeast by shaking the packet of yeast before you pitch it!

 

[ClarnoBrewer]

I make a 5 gallon starter. Then I don't even have to brew beer. I call it no-brew pitching. It's the latest awesome-alternative-cutting-edge-unique method. You have to use pre-hopped yeast, though.

 

[rollinred]

I use secondaries for my starters :rockin:Its the only way to go

Now that's funny!.....even for a Colt's fan.

 

[bwomp313]

earlier people were talking about how the liquid yeast companies say that their yeast is ready to pitch for 5 gallon batches below 1.060. my thought on this is that they don't want to have to sell larger pouches for more money because people new to brewing wouldn't want to spend that much money as liquid yeast is expensive as is. They'd just go with the dry stuff.

So many ways to brew. That's the most fun part about the hobby.

+1 CB. Best advice given on this thread tonight. IMHO.

 

[Skagdog]

so........what you're saying is don't make a starter and don't aerate? or is it do make a starter and don't aerate? wait maybe it's make a starter and aerate. Yeah, it's either that or don't make a starter and do aerate.

Got it, thanks for the advice!

^^^^JOKE^^^^

+1 for the diversity of the learning process and developing a personally efficient brew day!

 

[ClarnoBrewer]

Or just go buy a 4-pack of DFH! Wait, it's over-rated. Maybe that's a different thread...

I think what we all learned here is to stop telling n00bs that their beer has stalled at 1.030 because they didn't aerate with dry yeast. Especially after they tell us it's fermenting at 50f with 5lbs of crystal malt in it.

 

[jonmohno]

I think saying do what works for you is too black and white.Its way too hard to tell if wether or not aerating or not did good or bad for your beer.Oxygen is gennerally good for yeast, ive seen a few brands that say its not neccessary,and people that have no problem with it.Sometimes you dont know whatto do that what works for you,involves whether its pitch rate,starters,aerating,water ph.etc...... Im still not shure but have a good assumption my water has more to do with anything really. But that is not doing what works for me,because i still dont know., In the mean time there is always still good beer to drink. And this post may have just made every body all the dumber for reading it,ha.

Yeah ,just dont tell that to Sam. Im seing your dead people too. What? Yah it seemed weird but was somewhat brilliant and dumb at the same time,again,what?

 

[ClarnoBrewer]

Nah, I actually take Sam's side in that one. I was just trying to stir things a little more. Dunno why. This thread has turned into an opportunity to be ridiculous.

[seabass07]

I guess I'm a bit late to the party.

Safale us-04 says to sprinkle directly into the wort. It doesn't say anything about rehydrating. I do agree that the instructions are messed up. I don't understand why whitelabs says a vile is good for 5 gallons of 1.060 wort and then works with Jamil with his calculator and a book saying the opposite. I have a hard time believing what they are saying with so many contradictions.

That said, I'll have to try not aerating next time I use dry yeast since people's results seem to back up the no aeration thing. Since it really is all about the beer, use what works.

 

[SwampassJ]

Right, and who is making 3% beer here? I want them BANNED!

We are the 3%.
