Treat the barrel rule as the endpoint of learned practice and market preference, not proof of one inventor. Evolutionary adoption is Cowdery's reconstruction. A red-whiskey reference does not uniquely establish charred new oak or date its first use.
Cowdery surveys barrel construction, charring explanations, maturation, and early terminology while warning against retrospective invention stories.
Cowdery proposes that charred-new-oak aging emerged cumulatively rather than through a documented single invention. His references to red whiskey and transport/storage practices are clues in that reconstruction, not unique proof of cooperage method.
