Packaged Facts

The report comprises two volumes: the first, Market, Products and Trends, analyzes sales and growth potential for gourmet and premium foods and beverages, focusing on ready-to-eat meals (including frozen, refrigerated, and shelf-stable meals, soups, appetizers, and frozen pizza); baked goods (from artisan breads to crackers, cookies, and cakes), pasta, and grains; cheese; fresh produce (including packaged salads); condiments and sauces; candy, both chocolate and non-chocolate; ice cream and frozen desserts; and non-alcoholic beverages (from bottled water and ready-to-drink “adult sodas” to specialty coffees and teas).

Volume 2, Consumer Profiles, lays out the demographics for gourmet consumers overall and for the strongly gourmet-oriented “foodies.” Coverage includes data on weekly grocery shopping expenditures, responsiveness to grocery advertising media, and patterns by supermarket chain (ranging from Wal-Mart to Whole Foods).
