Kick starting stuck fermentation with fermenting wort?

[puravida]

I have two brews on the go at the moment started within days of each other.
One stopped bubbling after 48hrs and it still a good 10 points away from it's FG at the dreaded 1020 where a number of my past brews have stuck.

The other is still going like the clappers.

The only difference is I rehydrated the yeast for brew number 2 about an hour before I pitched it. (great advice from this forum!!! :thumb: )

My question is - can I take a sample of the wort that is fermenting and stick it in the stuck batch to kick start it???
How much? A 100ml turkey baster full perhaps?? :hmm:

How about syphoning some of the yeast from the bottom of your fermenting brew and adding that.

that's a good idea....

Though i think normal instructions normally say rehydrate for 15 mins, stir, wait another 15 mins, then pitch. Don't know what difference doing it for an hour would make.
