The pH above which sulfite alone isn't enough for a cider.
At pH 3.8 the free SO₂ needed for 0.8 mg/L molecular is over 100 mg/L, which
is more than most brewers will add and close to legal limits. Lea's advice
for a cider that high is to acidify first. Above this pH the explanation
adds a note saying so.
