Reusing yeast from current primary

[djonesax]

I want to brew a beer this weekend and harvest some yeast from a batch that I have had in the fermenter for 6 days and it still has some krausen on top. I have washed yeast in the past and have used slurries, but has anyone ever tried just taking a pint out of the primary with some of the krausen and dumping it into the new wort?

Unless one is performing a science experiment, pulling a pint of fermenting wort to inoculate another batch is going to be an epic underpitch that likely will not end well...

Cheers!

Lol. Noted...

It's a little late now (ideally done during the most active fermentation), but look into top cropping.

Thanks I did look into it after asking the question and may do it next time. Could I crop top directly into another wort?

That's the best way to do it. I would time my brews accordingly.

Not all strains work particularly well. The yeast-forward ones (Hefe, Belgian, English) strains tend to work best.

I just dump a new, usually bigger beer, on top of the yeast cake. Great way to make a starter!

It's also a great way to grossly overpitch...
