Introduced last summer, the line is already a $1 billion brand.

MINNEAPOLIS — Target is bolstering its year-old private-label Good & Gather grocery brand via the addition of hundreds of new items as well as the introduction of premium foods under the new Good & Gather Signature label.

New premium offerings will include small-batch Italian sauces, specialty coffees and gourmet pastas and pizzas, Target said in announcing the expansion, which rolls out this fall.

An addition of some 600 new offerings will take the Good & Gather line to 2,000 items, making it Target’s largest in-house brand by assortment. Good & Gather is already a $1 billion brand for the retailer.

“Food plays such an important role in our guests’ lives,” says Stephanie Lundquist, executive vice president and president, Food & Beverage, Target. “And now, as guests are eating and cooking at home — and appreciating good value — more than ever, Good & Gather’s delicious, high-quality assortment and affordable price continues to set Target apart, while helping our guests discover the joy of food every day. And they’re going to love what we’re serving up this fall.”

The new items will appear at Target stores in dairy, coffee, deli, bread and baking, snacks, produce, beverage, meal essentials, frozen and frozen seafood displays. Select items will also be available on the company’s e-commerce platform.
