Definitely a ton of whole grains in NB one. I tightened my corona down a smudge after that grind there and it's friggin pulverized it! I can't believe the different feel of stirring it in to the water, will see if I hit target. Mashing as we speak, I might have to back off a tiny bit next time bc I really don't want tannins.
Keep an eye on PH and you will not have a tannin issue. a 24" french whip is pretty awesome to mash in with if you decide to keep it tight. they are like 10$ off amazon.
