Stirring Fermentation

[Yamamotors]

Hello guys!
I've been thinking lately about using the stirring plate with the fermentation bucket.
The rationale: rousing top fermenting yeasts back into suspension.
The theoretical risks: oxidize the precious beer and putting yeasts on mechanical stress.

Any thoughts or previous experiences?

Ill be interested in this as well. I have been considering this for a lager fermentation using immobilized yeast. I think co2 in solution also stresses yeast. Stirred fermentation would probably reduce co2 levels during the process.

I'm also interested...I wonder how well it would work on those pesky, super-flocculating british yeast strains that like to drop out so quickly...maybe if you could turn the speed way down so that the yeast is kept in suspension but not in a raging whirlpool.

Would oxidation be that much of a concern in a Carboy with a stopper and airlock?

Indeed, so I can only figure the mechanical stress issue now...

I think you will find the information you want here.

My mistake; Chris Whites' comment about making a thin beer by stirring fermentor is not in the book.

if the yeast were not already stirring the whole deal i'd say this was a good idea. a solution looking for a problem.

Ok, sorry for wasting your prrrecious time!

oh, don't think that! there is a long thread on here where someone made a huge stir plate for their carboy, look it up.
