Introducing Temperature State: An Omni Lens for Food
Shoppers choose food by temperature state—Fresh, Frozen, Refrigerated, or Shelf Stable—across in-store and online channels, and those decisions shape broader consumer behavior trends across U.S. retailers. Until now, there has not been a single, comparable way to measure those choices consistently across banners, fulfillment models, and retail environments. NIQ Expanded Omnishopper’s Temperature State closes that gap with an omni-consistent view of shopper insights that helps retailers and manufacturers quantify missions, substitution, and cross-channel movement. In practice, Temperature State reveals who is buying, what they are switching to and from, and where dollars are leaking—so teams can make better decisions on assortment, space, pricing, promotion, and activation.
First in a series: Temperature State raises new questions—so we’re publishing a short series on the most debated topics in U.S. food retail. This launch article focuses on Grocery Center Store (Shelf Stable)—separating facts from assumptions about what’s driving sales. Coming next: Article 2: Amazon same-day delivery update.
How Temperature State Works
Temperature State groups Grocery Food purchases into four easy-to-read temperature forms—Shelf Stable, Fresh, Refrigerated, and Frozen—using a single, consistent approach across in-store and online transactions (including both UPC-coded and random-weight items).

Three Center Store Myths Temperature State Finally Busts
Myth 1 — “Center Store is a drag on Grocery Food sales.“
Reality: Grocery Center Store (AKA Shelf Stable) remains foundational to Grocery Food and contributes meaningfully to growth. When you view the latest 52 weeks of data by temperature state, Shelf Stable’s contribution is proportional to its size within Grocery rather than underperforming.
Implication: Treat Shelf Stable like a growth platform—not a down lever—by protecting availability and promo where it’s driving gains.

Myth 2 — “The Grocery perimeter is stealing Center Store sales.”
Reality: Temperature State shows that while Grocery Shelf Stable is growing overall, some Shelf Stable dollars are shifting—and that net movement is not to Fresh, Refrigerated, or Frozen items within Grocery. Instead, the shift is largely cross‑channel, with Shelf Stable sales moving to Shelf Stable formats outside Grocery, rather than to the Grocery perimeter.
This indicates that competitive pressure is coming from where shoppers are buying Shelf Stable items, not from increased substitution within the store.
Implication: To sustain Shelf Stable growth within Grocery, prioritize strengthening Shelf Stable competitiveness outside Grocery—including pricing, availability, pack architecture, and channel presence—before focusing on perimeter adjacencies that may not address the true source of sales shifting.

Myth 3 — “Grocery Center Store growth is driven only by price inflation.”
Reality: While price plays a role, Grocery Center Store growth is not driven by price alone. Temperature State shows that changes in buyers and occasions also contribute meaningfully to performance. By separating growth into its core drivers, teams can see whether Shelf Stable gains are coming from more shoppers, more trips, or pricing effects, rather than assuming inflation is the sole factor.
This creates a more complete and accurate picture of what’s actually powering category performance—and challenges the idea that Shelf Stable growth is merely a price story.
Implication: Use the NIQ Expanded Omnishopper driver view to identify the right growth lever—win more buyers, increase shopping occasions, or optimize pricing and pack architecture—because each requires a different commercial strategy.
