Cold Crashing

Any tips on effective cold crashing and for how long to do it.

To cut a long story short, I've dry hopped my beer without bags using both pellets and leaf but they are now floating on the krausen. I'm hoping they'll drop naturally but no sign of it yet.

If i cold crash before bottling:

a) how long do I it for?
b) what temp do i do it at?

NB* disclaimer: it is an NEIPA and i did think about entering into the comp but I'm not now as it definitely won't be ready in time!

The NEIPA comp isn't for a month, that's plenty of time to cold crash and carbonate it.

To answer your question, as cold as you can get it without freezing really. 1c to 4c would be optimal. If you have a fridge, that's ideal, if not, I once cold crashed using a bucket of icy water. Stick a few ice cream tubs of water in the freezer and you can have decent blocks of ice made up in a few hours.

Leaf hops you should be able to filter out using a muslin bag over your siphon.

Thanks! Yeah I got a fermentation with temp control so i'll see how low I can go.

its tasting good so far, murky as hell but fermenting nicely.

Peeking inside the fermenter to add hops and seeing the sea of green muck, heaving and burping c02 every so often was an experience...it felt like I was looking a delicious smelling green smoothie going by the smell

I did the same with NEIPA from Wee County's recent brewday in Boyne Brewhouse. Dryhopped with pellets, like I usually do, but was left with a shitload of them lying on top of the krausen.
I crashed to 3deg for 24 hrs just, cos I was worried about losing the cloudiness you want for a NEIPA.
Worked out grand, all the hop material crashed out, but I was left with the little cloudy beauty in the attached photo.

Well would ye look at that.   8)

So I set the temp to three yesterday, thinking it would drop quick but its slow. It was 12C this morning, and I could see the hop pellets dropping slow.

So does cold crashing for 24 hours mean dropping to the desired temp for 24 hours or actually holding at 3C for 24 hours? I don't want to overdo it.

Only held it at 3 for about 12 hrs, it took a fair while to get down to 3 (had a higher than normal ferm temp of 23)

I did a 200g dry hop there Thursday morning, started dropping Friday morning, kegged Sunday afternoon. Only got to about 5C, but it was enough to drop the hops, even with no gelatin or fining.

Here's a screengrab from the BrewPi log of it.
