Buckwheat honey is a highly nutritious honey made by bees that collect nectar from buckwheat flowers. Buckwheat has tiny flowers, which means bees that make buckwheat honey have to work extra hard to collect enough nectar. Buckwheat honey can range in color from dark purple to black. In general, it looks like your average, amber-colored honey with a slight reddish tint. Buckwheat flowers are often dark in color, which leads to the rich color of buckwheat honey. Buckwheat honey isn’t as sweet as traditional honey.
