Cream of tartar crystals

False colour scanning electron micrograph of crystals of potassium hydrogen tartrate, also known as cream of tartar.

Grapes are unusual in that they produce large quantities of tartaric acid, together with some malic acid, whereas most fruits contain citric & malic acid. Magnification: X 40 at 6x7cmsize.
