Decaf Stacking Caffeine Rule
The decaf stacking caffeine rule counts multiple decaf cups toward daily totals—afternoon stacks can still delay sleep for sensitive users.
The decaf stacking caffeine rule treats multiple decaf coffees, large decaf cold brews, and decaf green tea as additive—often two to fifteen milligrams per eight-ounce cup, which adds up after four afternoon mugs. Sensitive sleepers may need a true herbal cutoff, not unlimited decaf.
Label Swiss-water process does not mean zero.
