Coopers NEIPA

So, I would take another FG reading and bottle. I have a brew in the shed thats done but sometimes still bubbles. I will take another reading today .
Had a late night last night with Gash on his Video cast thing so i wont be kegging today Lol.
But the only way to know if your brew has stopped fermenting is by taking another reading. Yeast are funny critters. Dont worry about the Krausen sometimes it just wants to float and I dont know why. Cheers mate. It will be awesome.

Its just the hops, they up the wort, nucleation points etc.. this is where cold crashing will drop it out fast, 2 or 3 days, Cheers!~

Nice one, cheers

At the end of the boil
Probably best to watch the video if you havent seen it.
yeah you dry hop early in the ferment, about day 3, then again once ferment is just about finished, usually day 7 or 8.
The dry hop can be the same hops yes, and the same amounts, its up to you, but more hops in a neipa is good, just gotta watch your fermenter type and how much hop you can use before its just going to be coming out the tap. You can split the 40/40/20 in two if you like and use that or go whole hog and use that amount each dry hop.

Ok. Sometimes I do a one dry neipa, sometimes I do a two hop, it kind of depends on how fast the yeast is working, if its going well and fast the often isnt much time for two dry hops.
In regards to bitterness you wont get any real bitterness from dry hops, only chance there is if you get hop matter into the final beer which we try to avoid, and what is sometimes called perceived bitterness, but the amounts we are talking here that shouldnt be a problem.
Cascade instead of centennial will be fine, its a little less "powerful" but just as tasty and just as aromatic, some would say its a better choice for dry hop.

My suggestion would be, since you're worried about the amount of hop debris would be to add the first dry hop when you pitch the yeast, so maybe 20g each of citra/cascade/galaxy.
I would pitch two packs of yeast if you can.
Follow the ferment, keep an eye on it. When you see the krausen (foam on top) drop down, it maybe 5cm thick after the first 2 or 3 Days, when you notice it drop too about <5mm thick, often day 5 or 6 then dry hop the second time., 20g each of citra/cascade/galaxy. or if taking readings once it gets to about 1.018, at that time you raise the temperature of the ferment if possible a couple of degrees and the beer should be done in 3 or 4 days.
Do not let an NEIPA sit for 2 or 3 weeks in the fermenter. It shouldnt take that long, healthy yeast pitch.
Then be extremely careful with bottling or kegging, no bulk priming, no shaking bottles, avoid oxygen at all costs. Plastic bottles are the best for neipa, two carb drops, squeeze air out and cap. Drink ASAP as soon as the bottles feel very hard, maybe a week, maybe 2, stick one in the fridge and try it. This is not a beer to age. NEIPA is one hard beer to get right! Keep the faith though
I think thats it!
Keep asking questions if I've missed something, Cheers!
