This set contains one vial each of yellow mustard seed, brown mustard seed, horseradish powder, sea salt and instructions, an empty 6 oz. jar to store your finished mustard and a blank tag for labeling! Comes with (almost) everything you need to make your own beer mustard. Just add white or apple cider vinegar and the beer (or hard cider) of your choice. If you do not want to use alcohol, we offer an alternative recipe with just vinegar. All instructions included. We pack in small batches so you can be assured the spice you are getting is fresh, flavorful and aromatic. You'll smell and taste the difference right away. You care about what you eat. We do too.
