I know I'm resurrecting an old thread here, but I have brewed a couple beers with this malt now, so I figured I would chime in.
The comparisons to continental pilsner malt are off - this is more akin to a British pale malt. I got more color from it (in a SMaSH), than I ever got from Fawcett or Simpson's MO or GP. Also, the salted popcorn thing isn't how I would describe the flavor, but I understand where they're coming from. I would describe it more as bready. However, where I find maris otter, optic, halcyon, and golden promise to all be pretty smooth and slightly sweet compared to, say GW Pale Ale Malt; this malt is not only sweet, but very bready and bold. I used it in a strong US-hopped bitter (SMaSH w/Ahtanum) and in an American brown ale. In both beers the base malt stood out too much for me. I won't be buying it again, but I could see it working in smaller quantities in place of Vienna malt, perhaps.
