Harvey Wallbanger I can be made!". Notes Harvey Wallbanger The Harvey Wallbanger is a mixed drink made with vodka, Galliano, and orange juice. The Harvey Wallbanger appears in literature as early as 1971. The cocktail is reputed to have been invented in 1952 by three-time world champion mixologist Donato "Duke" Antone, and named by Antone after a surfer frequenting Antone's Blackwatch Bar in Los Angeles. However, recent research by culinary historians casts doubt on this theory. Robert Simonson goes so far as to say that "no sane person ever believed that story." Simonson emphasizes the lack of a historical record for any
Orange juice d-galacturonic acid unit along with blocks of L-rhamnose regions that have side chains of arabinose, galactose, and xylose. Pectin methyl-esterase is the enzyme responsible for hydrolyzing carboxymethyl esters and liberating free carboxyl groups and methyl alcohols. The free carboxyl groups interact with cations to form insoluble pectic acid divalent metal ion complexes. These metal ion complexes precipitate in the juice and carry all the colloids in orange juice with it. The enzyme would flocculate the cloud and clarify the orange juice. Thus, in order to keep the orange juice cloud intact, it is vital to inactivate pectinesterase. Pectinesterase is inactivated
