My guess offhand is that they keep enough empties on hand to make sure there's a good supply. Checking around on the web, I've seen that it's not just Gallo that ships outbound loads, but other food and canned goods suppliers. As a result, you're going to see a lot of insulated and plug-door cars, at least on outbound loads, but you're also going to see lumber coming inbound for the transload.
