GLUTEN FREE CONFIDENCE SCORE: 8/10

Despite its name, buckwheat actually does not contain wheat and is gluten-free. Therefore, buckwheat flour is usually gluten-free – the main reason that it may not be totally gluten-free is if it is produced on shared equipment (therefore making is susceptible to cross-contamination). One brand of buckwheat flour that we know is certified gluten is Arrowhead Mill buckwheat flour.
