Provided herein are methods of producing (+)-manool comprising: contacting geranylgeranyl diphosphate with an copalyl diphosphate (CPP) synthase to form a (9S, 10S)-copalyl diphosphate wherein the CPP synthase comprises an amino acid sequence having at least 90%, 95%, 98%, 99% and 100% sequence identity to a polypeptide selected from the group consisting of SEQ ID NO: 1 and SEQ ID NO:2; and contacting the CPP with a sclareol synthase enzyme to form (+)-manool.
