Liquor sampling jobs refer either to quality assurance positions in which you sample liquor during the distillation and aging process to ensure that liquor meets quality standards, or else to a position as a sales representative for a liquor distributor or liquor company. As a sales representative, your duties are to host in-store tasting events at liquor stores to promote an alcohol brand, attend trade shows and other festivals, provide free samples and product knowledge to customers or potential customers, and answer questions related to your employer’s products.
