Question: Ken and Jackie Smith just purchased a small winery in the Napa Valley of northern California. One thing they noticed when they were investigating the winery is that the owners never placed the "100% Napa Valley" certification mark on their bottles. Now that they own the winery Ken and Jackie are looking into using the mark. Investigate what is required to place the "100% Napa Valley" certification mark on a bottle of wine. If Ken and Jackie's winery qualifies, should they use the mark?
