The spunding pressure for the pressure-lager primary, in psi.
This is a named constant because PRESSURE_LAGER_CRASH_PSI only makes
sense next to it, and the difference between the two matters. 15 psi is the
middle of the published homebrew guidance. Brülosophy's pressurised-lager
exBEERiments and Brew Your Own's "Fermenting Under Pressure" both work in
the 10–20 psi band, with 10–15 psi quoted as enough to hold esters down at
ale temperatures.
