DIP Hopping

[John Holgreaves]

I am guessing that DIP Hopping for 50 mins. at 70C will yield about 5% IBU's . Anybody know how to calculate this more accurately? Thanks

What is DIP hopping?

What is DIP hopping?

Adding hops to your fermenter and then steeping in wort or water at 70c for 50 mins or so. I do this while I boil the wort.
Loads of information on the net for the finer points and advantages. I have done about 10 brews with this method and I am very pleased with the results.

Presumably you mean steeping then adding to the fermenter, not the other way around.

No steep in the empty fermenter.

Am I missing something, or isn't this basically the same as adding a late hop addition after the wort has cooled to 70°C ?

The hops stay in the fermenter after yeast has been added.

Theory is the myrcene is gassed off during the hop dip, and biotransformstion occurs once yeast gets to work which means you have more of the fruity compounds from the hops and less of vegetal ones.

It will depend on quantity and AA of particular hop.

At 70c you are getting about 10% of the equivalent boil ibus for that time I believe
