"Grape-Must" represents a complete guide to processing grapes for the purpose of wine making, written by F. T. Bioletti. Frederic Theodore Bioletti (1865 - 1939) was an English-born American vintner. He studied at the University of California, Berkeley from 1889 to 1900, where he worked with prominent soil scientist Professor E.W. Hilgard. His work with Hilgard on the fermentation of wines under different conditions were significant in helping California vintners to refine their wine production practices and improving the resulting wines. Bioletti was the first chair of the Department of Viticulture and Enology and founded the grape breeding program at the University of California Agricultural Experiment Station. In this volume, Bioletti outlines the various steps of grape processing from extraction to bottling, making it a must-read for those with an interest in winemaking and its basic processes. Contents include: "Gathering and Care of the Grapes", "Extraction of Juice", "Sulfiting, Settling, Racking, Fining", "Final Clearing", "Pasteurizing, Settling, Addition or Acid, Filtering", "Conversion", "Bottling", "Corking", "Sterilizing", etc. Many vintage books such as this are becoming increasingly scarce and expensive. We are republishing this volume now in an affordable, modern, high-quality edition complete with a specially-commissioned new biography of the author and introduction on winemaking.
