The Liquor the Marc Keeps

Closing the Dry-Matter and Anthocyanin Balances of Twenty-Four Pilot Decoctions of One Lot of Roselle Calyces

A paper from the School of Underlying Conditions follows the dry matter and the monomeric anthocyanin of twenty-four pilot decoctions of one lot of dried roselle calyces into the extract, the liquor held in the spent marc, the marc solid and an unrecovered remainder. The dry-matter balance closes in every run while the anthocyanin balance closes in none, its shortfall rising with hold time from a fixed loss of about 5%, and the free-drained marc keeps a richer liquor than the bulk, which pressing recovers.
