The chardonnay grape juice undergoes a two-stage fermentation process in oak barrels The riesling wines are aged in the stainless steel tanks for approximately a year The chardonnays are aged in the oak barrels for about two years A machine bottles the wine and corks the bottles Each bottle is manually labeled with the name of the vintner, vintage, and variety The bottles are manually packed in 12-bottle cases The cases are hand-stamped with the same information that the bottles received The wine is shipped to wine distributors and retailers, mainly in central New York Generally, about 100 cases are shipped at a time This is done during the slow winter months This is done when needed, and on a routine basis for preventive maintenance
