The alcohol may be a monohydric alcohol and an aqueous alcohol, such as an aqueous alcohol having a concentration of at least about 15% alcohol-by-weight. The low-free fatty acid phase may include oil and at least one impurity. The low-free fatty acid phase may be cooled, and the oil may be separated from the at least one impurity.
