As we replace bonding pairs with nonbonding pairs the molecular geometry changes to seesaw (four bonding and one nonbonding), T-shaped (three bonding and two nonbonding) and linear (two bonding and three nonbonding).
There are 12 bottles in a standard case of wine. Each of those bottles normally contains 750 milliliters of wine, giving the case a total of 9 liters. If a case contains anything other than 12 bottles, the wine manufacturer or seller usually notes the change for consumers.
Mechanization creeps into hand operations over time and sparkling wine is no exception. Although we could riddle all the bottles by hand, it is cheaper to do it in bins, 400 bottles at a time. Four hundred bottles are stacked upside down in a square bin about 3 feet on a side and 3 feet high.
