Plural of bottleful; multiple amounts of liquid, each equal to what one bottle holds.
Standard English pluralization of 'bottleful' using the -s suffix. This is the common modern plural, though 'bottlesful' is an alternative.
English plurals are wonderfully weird—most people say 'bottlefuls,' but technically 'bottlesful' (plural of the bottle, not the -ful) is also correct, showing how English speakers instinctively pluralize the container rather than the suffix.
