I think haziness is from the hops, murkiness is from the higher % of oats. Once I started getting into the 15% range, it stayed juice like even after 2+ weeks in the keg.
I usually use 5-8% flaked oats in most of my beers in addition with wheat (5-30%) depending on the beer...saison, wit, stout, pale ales, IPAs etc.
Ive done multiple hop experiments...large whirlpool, dry hopping on day 2 of fermentation, double dry hopping. Used various yeast and they all eventually drop out pretty darn clear and I don't use any finings.
It wasn't until I doubled the oats, that the murkiness stayed.
The last 50 gallon batch we did was a partigyle IPA and Pale.
The IPA, late hopped, whirlpooled and double dry hopped split into multiple fermenters with 007, 1318, conan, 644, s-05. all murky.
The pale ale. all boiled hops. split with 1318, 007 and s-05. some dry hopped, some not. I'd say about 1/2 the hop additions as the IPA. but all were still murky. water profile was the same 150/100 in favor of chloride
I like hazy IPAs, the murkiness doesnt matter to me, but serving it to people that dont know the trend, they always raise an eyebrow. And then after they taste it, theyre like whoa! ok, nevermind. so it would be great to get the flavor profile without the murkiness. if thats possible.
