Just thinking out loud, if these were traditionally in wooden barrels, then would the bung stave not act like a blow off valve?
So Im thinking that a PRV as your primary blow off with your spunding valve set at 5psi higher acting as a backup just incase the PRV fails would keep it more in line with the style.
Im thinking that just using the Spunding valve would be the same process that we already use to ferment and serve from a single pressure fermenter.
Secondly what would the serving temperature be to keep it true to style. warmer it is the greater the pressure needed to achieve specific volumes of co2 . So if this is being served warmer you could in theory get away with a bit more pressure in your keg.
i may be wrong.
