The olives are soaked for 30 to 40 days in a solution of water and salt (brine.) Sometimes the olives are soaked in fresh water first before being brined.
The brine solution has to be changed frequently during that period, because the olives ferment in it. As they ferment, they create lactic acid, which helps to give brine-cured olives their typical sour taste. The olives end up with shiny, smooth surfaces.
The brining not only removes bitterness but seasons the olives as well. The olives, though, will end up saltier than Lye-Cured Olives would.
After brining, the olives are either pickled or preserved in an oil marinade.
Brine-Cured Olives cost more than Lye-Cured Olives because the process takes longer.
