Two industry heavyweights spell out how great wine is made, keying on the critical decisions - and their ramifications - made at every step. The specific how's and why's of grape growing: fertilizing, canopy management, crop thinning, soil types, climate differences, etc., and then on to winemaking: sulfur additions, cold soaking, fermetation vessels and temperatures, extended maceration, aging, racking, filtering, etc., right up to and including bottling, and how each decision affects the final product. The differences in growing/making light vs. full bodied whites, reds, sparklers and dessert wines. Excellent sections on the use of oak, wine faults and more. Good stuff. Read it.
