Filling without a line
Updated
Hand filling a still drink is straightforward. Hand filling a carbonated one is the hardest manual operation in this estate.
What is actually hard
Carbonated liquid degasses when it meets air, so an open pour foams, loses carbonation and gives an inaccurate fill.
And a live product is warming while you work, which speeds everything you are trying to control.
Still products
A gravity filler with a bottom-up fill tube, or at minimum a tap and a funnel with a fill line marked.
Fill cold where the product will be sold cold, so the fill level is right at the temperature it matters.
Fill by weight if accuracy matters, which it does for the declared net quantity.
Carbonated products
Cold is the main lever available without equipment: near zero, and keep the product cold in the vessel rather than chilling only what is in the filler.
Fill slowly, down the side of the bottle rather than splashing.
Cap immediately. The seconds between filling and capping are where carbonation leaves.
A counter-pressure filler is the real answer and it is a purchase rather than a technique. Below that, a bottle filler that seals to the neck and fills from the bottom is a meaningful improvement over a tap.
Keeping it sanitary
Sanitize bottles before filling. Not optional in an unpasteurized product, and frequently skipped.
Sanitize the filler, the tubing and anything the product touches, and do not leave product standing in tubing between runs.
Work in a clean area separate from where fruit and dry goods are handled.
And keep the run short. A batch being hand-filled over three hours is a batch spending three hours warming and meeting air.
