Harvesting Yeast from bottle dregs...

Posted by wyzazz on January 3, 2012 at 10:50 AM

So here is the situation, I want to brew a Chimay Blue clone but I don't have any Wyeast 1214.  Sure, I could buy yeast from the LHBS but that would be the easy way out.  So I pulled a bottle of Chimay Blue (Grand Reserve) from the kegerator and popped the top!  Poor me, I need to drink the whole thing to get to the dregs at the bottom.



So I began the arduous task, a piece of sanitized foil, tulip glass & spray bottle of sanitizer to start things off.  I popped the cork and poured my first glass.  Then I spritzed the neck/mouth of the bottle with Star San and capped it with the sanitized foil. 


Next I made around 3/4 of a pint of 1.020 starter to step the yeast up slowly and delicately.  3/4oz of DME and 3/4 pint of water will give you approximately 1.020 wort so I put this all in to a saucepan with a pinch of yeast nutrient and boiled for 15 minutes.  Once finished I put the covered pot of wort in a water bath and sanitized a pint mason jar to prepare it for the yeast starter.  Oh, and had another glass of Chimay.  ;)



After the wort was cool I added it to the sanitized mason jar and had another glass of Chimay, to get down to the bottle dregs.  After sanitizing the bottle mouth one more time I poured it in to the mason jar and set it down in the basement on the kegerator to (hopefully) ferment and create a nice fresh culture of Chimay Yeast. 



Once I get some activity in this small starter (it can take 4-5 days when stepping up from bottle dregs) I'll let it ferment out and put it in to a 1 quart starter @ 1.030 to grow more, and then yet again with a 2 quart starter @ 1.030 to grow again.  This will give me enough yeast to build up to a proper starter based on the gravity of my beer.  It's a little bit of work, but well worth the results!

I'm fairly sure I've read that Chimay uses a different strain at bottling then from the yeast they use for fermentation but I could be wrong. Denny Conn's stated that it's the same strain and I can't for the life of me recall where I read what I did. Either way cool write up and looking forward to seeing how it comes out.

Thanks, we shall certainly see how it all turns out. I've stepped this up 3X so far, now I just need to make some time to brew!

My starter turned cidery and sour smelling, didn't taste all that good either. It was a very dark color and didn't look appealing at all. I ditched it. I read of a few others having the exact same experience when harvesting from Chimay bottles so I don't feel too bad about it. I suspect that this is a different strain than their fermentation strain as you mentioned. Looks like I'll pick up some yeast from the LHBS for my next Belgian. ;)
