You probably didn't know, but National Mustard Day was on August 1.
A brewer is celebrating by adding the spicy condiment to its beer! 'Oskar Blues' has teamed up with French's Mustard to make a mustard brew.
It's available at its taprooms in Colorado and Brevard, North Carolina - which is near Asheville.
By the way, National Mustard Day was created in 1991 by The National Mustard Museum in Wisconsin.
