Adding yeast at bottling..?

Post by darthballs » Sat Jul 27, 2013 3:39 pm

I am just bottling a dubbel (in 330ml bottles) I have brewed at 8.2% and am toying with adding some T-58 to about 10-15 bottles to compare the difference. Anyone have any thoughts on this or tried it before? Also how much because I have no idea how much to add to each bottle..??

To note, I am also adding sugar to each bottle as the last couple of times I have batch primed the bottles have been a tad flat...

Cheers

Back in the day I used to add fresh yeast to beers I had lagered as they looked bright, like there was no yeast left, but I tried a few without repitching and they still carbonated. I have never repitched since. I don't know how long you have been bulk conditioning your dubbel, but I never add more yeast at bottling time anymore. I think you only need to do this if you filter your beer. I have lagered vienna lagers and Bocks for upto 6 months at 2C and just racked off, batch primed and bottled. No need to repitch fresh yeast. It may take 3-4 weeks to fully carbonate after lagering, but it is still conditioning in the bottle, so what's the rush.

If you do want to repitch you should skim a spoonful of the krausen off the top of an active ferment and add that to your bottling bucket. It doesn't need much. I don't think it'd necessary though and you are just introducing another risk of infection.

By the way be careful adding extra sugar to your bottles and bulk prime in a bucket, you could end up with bottle bombs. I usually add 70g of dextrose (boiled for 15 minutes) to the bottom of the bottling bucket and then rack the beer on top of that. Give it a little stir when it's finished and that's it. I never have a problem with under carbonated beer. Belgian beers can take a little more fizz, but I would say 120g max for a 5 gallon brew.

HI there,

thanks for the advice on the yeast, as I'd had zero replies I decided against adding any yeast as the brew had achieved my expected gravity 1012 at bottling so I am happy with it. Now it's just the waiting. A week or two in the house and then plunge it into the back of my garage/brewery with it's nice darkness and consistent cool temperature. Time will make this a winner I am sure. I just need to be more patient, think I have been drinking my more recent brews too rapidly. I'm gonna leave this at least 8 weeks before I try even one bottle. I didn't batch prime this brew at all, I only put a painstakingly measured teapsoon of sugar into each bottle so I shouldn't get any bombs.

I will post up the brewday and pics in the next few days as I have several to catch up on the forums :D
