How about Breyers whipping air into the product to increase volume.

For all their recent faults, that's not something they do.

If you ever look at ice cream at a store at high elevation, the store
brands will typically have the lids popping off from the expansion of
the excessive air. The Breyer's and the Haagen Daaz will have their lids
intact. I notice this whenever I'm up near Lake Tahoe and buy ice cream.
