I'm very partial to Austin Homebrew; fresh and can be purchased in 1 pound increments.
That said, I'm about to switch to either Briess Organic at Seven Bridges, or Northern Brewer's Organic because SWMBO wants organic. I prefer Northern Brewer because of reduced shipping time and a smaller size (3.15 lb), but my next order will be from Seven Bridges and the 4.4 lb LME because they have organic rye.
