Re: A bit of an oops with my Barley Mash
- Hi Gavin,
If you need to re-pitch yeast in the later stages of a fermentation, it
can be quite difficult. First off, you should always rehdrate dried
yeast from a packet before pitching and never pitch directly into a
The best way is to make a starter batch in a large jar say a quart or
so, add some sugar (1/8th pound or so - 2 oz.) and some nutrients (1/2
teaspoon) along with no hotter then 110F water. Add your dried yeast
and let sit for about 10 minutes. Cover with plastic or a cover with a
hole and give it a shake. You can let this sit for overnight giving it
a good shake a few times to aerate it and next day or so, you should
have a nice starter with a good colony of yeast to pitch.
Here are a few tips for this from E. C. Kraus:
1. Pre-Start The Yeast. Make a wine yeast starter 1 to 2 days before you
start the wine. This allows the yeast to hit the wine with its feet
so to speak.
A yeast starter is simply a mixture of sugars with a boosted level of
nutrients, usually about 1 pint in size for every 5 gallons of wine to
made. Just mix it up, add the yeast, and allow it to do a
Once the starter's fermentation starts to slow down, it is then ready to
be added to the prepared wine batch, usually around 1-1/2 to 2-1/2 days.
This will give you much faster results and if it is a stuck
fermentation in the latter stages, by adding this to a small portion of
the stuck fermentation, you should see bubbles in a few hours. Keep
adding more of the stuck fermentation till it gets going again, provided
there is enough sugar left..... Frankly, I have not had a stuck
fermentation since i can remember.

re-pitching the yeast and adding sugar. How do I know the batch has
re-started? Will I get bubbling almost instantaneously when re-pitching
in the anaerobic phase? I ask because I always pitch from the packet and
don't use a starter, so it takes about a day for any action to happen.
