I don’t know if anyone bothers(because it can’t be stored just by pumping it back down an oil well, which makes storage costly relative to its value; and because siloing grain is just one step upstream and gives you more options); but if it were a priority I’d imagine that the thing you’d stockpile would be boring old Neutral Grain Spirit. Just dilute down from the factory-fresh 190 proof, flavor if flavor is a thing that the booze you are ‘producing’ is supposed to have; and slap a label and brand name suggestive(but not purporting to promise in a legally binding sense) of artisanal small batch production and an emotionally salient family history of excellence and you are good to go.
What would be interesting to see is how quickly(and whether fast enough to outpace some other measure being taken to improve truck driver availability by quietly walking something back that was previously touted as an unassailable principle of Albion) the supply and distribution chain could adjust to an arrangement where final dilution and flavoring are moved much closer to the consumer, so that only shipments of the comparatively high density and high versatility concentrate need to consume trucking capacity.
In principle it wouldn’t be rocket surgery; but I suspect that there would be some legal and practical headaches if you leapt in unprepared.
