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.
Regular hexagons have six sides of equal length and interior angles that add up to 720 degrees. Hexagons don't have to have sides of equal length, though. Any closed shape with six sides is a hexagon. Hexagons that have sides of unequal length can be referred to as arbitrary hexagons. However, in a neat turn, according to Wolfram MathWorld, connecting the centroids of any arbitrary hexagon will result in a regular hexagon with six equal sides.
