For a little while now I've been using https://www.epiphanymalt.com/ ,located in North Carolina.
Haven't used any of their malts that disappointed. Prefer grain grown/malted as close to me as possible.
A couple of individual crushed batches are ordered at a time from https://www.atlanticbrewsupply.com/ which is down the street
from Epiphany. I usually get the order in 2 days from UPS.
I just bought a sack of Peterson's quality malt pale ale malt here in Vermont. I'm excited to try it. It was actually competitive in price to what I can get from larger companies at my local shops. If it's good I'll buy their other malts too.
Brewing is just like baking and cooking. Using the freshest possible ingredients makes a world of difference.
Many here encourage supporting a LHBS, wouldn't that also apply to farmers and maltsters ?
For the scale of most homebrewers, grain cost differences are minimal, if any.
I'm picky on the ingredients chosen, currently on a quest to find the best dried bitter and sweet orange peel.
Ordering small amounts of each, smelling and tasting them, then tossing the losers.
For sweet orange the winner is

Pound is a lot, vacuum sealed in separate portions. No winner yet for dried bitter orange peel.
