Long story short, they are in the same plant family but contain different chemicals and therefore are used differently. Most importantly, I saw these 2 beers, had a chuckle, and decided they should be reviewed together as a theme.
O'Fallon Brewery is from Missouri. The label of their Hemp Hop Rye ale simply says it is a "malt beverage brewed with hemp seeds." Sadly their website does not currently have information on this beer and I'd like to know their intent. What kind of flavor or other characteristics do the hemp seeds add? This is a very pretty amber beer, with a sweet smell; I picked up on pears and a bit of the rye. The beer is a nice amber ale with a little extra flavor from the rye and caramel malts. Overall, very nice. I'd have this again. B+
