I don't know what kind of vanilla this is, but I opened it today and it has NO vanilla smell whatsoever.  I've never in my life seen vanilla like this.  In disgust, i rummaged around my cabinet and found another brand that I had from THREE years ago, opened it, and it smelled delicious.  Three years later!  This Nielson Massey one is going in the trash.  I recommend looking for a Mexican vanilla.
