A recipe I want to brew calls for 3 oz of roasted barley (300L). I was going to use Brewmaster's Warehouse as my supply source, but I noticed that they only offer "Simpson's Roasted Barley" which is listed at 500L.
Can I just sub 2 oz of this to maintain approximately the same color? What about taste? Will there be a noticeable difference between 3oz of 300L and 2oz of 500L?
