The yeast Saccharomyces cerevisiae Ellipsoideus is the strain most commonly used during wine production. This variety generally produces wine with an alcohol content of 6-14% and produces fermentation products that give different wines distinct flavors.
All internal angles are 120 degrees. A regular hexagon has 6 rotational symmetries (rotational symmetry of order six) and 6 reflection symmetries (six lines of symmetry), making up the dihedral group D6. The longest diagonals of a regular hexagon, connecting diametrically opposite vertices, are twice the length of one side.
A hexahedron is a polyhedron with six faces. There are seven convex hexahedra, corresponding through graph duality with the seven hexahedral graphs. The illustration below shows the seven hexahedra (top line), their skeletons (middle line), and the hexahedral graphs whose duals correspond to the polyhedra and their skeletons (bottom line).
