As folks are saying. Red vs White Oak is an availability issue. You can get white oak here but you have to go to a real lumberyard, not a Big Box store. When I was a student in Forestry school 50 years ago, one of our wood professors showed us the difference between red and white oak. He had two sawn sticks about 8mm square and 30 cm long. He took a drag off of his cigarette and blew smoke from one end to the other of that perfectly good red oak stick! It took some hard pressure, yes, but red oak is *that* porous. But you can't do that with white oak.
Barrel makers knew the difference ,and never made "tight" (waterproof) barrels from red oak, only from white oak.
