Bottling
Bottling for a gentle sparkle, and the spring two bottles went off
Most of what the plot makes is drunk still, straight from a jug. Some of it is bottled with a little sugar so that it opens with a quiet hiss, and learning to do that safely took one frightening spring and a good deal of sweeping up.

What a gentle sparkle actually needs
Bottle-conditioning is simple in principle. The cider finishes fermenting and is completely dry, a small measured amount of sugar is added just before bottling, the bottles are sealed, and the yeast still floating in the cider eats the sugar and makes enough gas to carbonate it. There is nothing to add the gas, so the fizz comes entirely from the sugar and the yeast, which is why the amount of sugar matters so much. Too little and the cider is flat with a faint prickle. Too much and the pressure inside the bottle goes past what the glass was made for.
The part that is easy to get wrong is the phrase completely dry. If the cider still has sugar of its own when it is bottled, that sugar ferments as well, on top of whatever was added deliberately, and there is no way of knowing how much it will add. For a light sparkle I now prime with about five grams of sugar per litre, dissolved in a little boiled water and stirred gently into the whole batch in a bucket, never dosed bottle by bottle. That has given a soft, beer-like fizz every time since the spring of the burst bottles.

The spring of 2024 and two bottles in the dark
In March 2024 I bottled a cultured batch that had been sitting at 1.006 for what I took to be long enough. It was clear, it had stopped bubbling in the airlock, and I wanted the carboy for something else. I primed it as usual, capped forty bottles and stacked them in crates in the cellar. Three weeks later I went down for potatoes and found one crate wet and smelling strongly of cider, and a bottle in pieces in the bottom of it. A second went while I was carrying the crates up the steps, with a noise like a small firework and a lot of glass on the stairs.
The batch had not finished. At cellar temperature in winter the yeast had slowed almost to a stop, the airlock had gone quiet, and I had mistaken slow for finished. Once the bottles warmed a little in spring, the yeast woke up and ate both the priming sugar and the leftover sugar in the cider. Every remaining bottle was opened outside, over a bucket, wearing safety glasses and gloves, and most of them fountained halfway to the fence. Nobody was hurt, which is luck rather than planning, and the log for that month is mostly in capital letters.

Bottles, caps and where they wait
The cider now goes into two kinds of bottle. Most of it goes into ordinary brown beer bottles with crown caps, collected over the year from anyone who will save them and checked for chips before they are used. The rest goes into swing-top bottles with new rubber seals, which are handier for taking to the plot but harder to trust, because an old seal can leak slowly and leave you with a flat bottle and no idea why. Clear glass is avoided. Cider left in light picks up a stale, cardboard taste within a few weeks, and the log has two sad entries that prove it.
After capping, the bottles spend about two weeks in the warmest part of the house, which is the cupboard under the stairs, so that the conditioning happens while I can keep an eye on them. One plastic fizzy-drink bottle is filled from the same batch and put in with them as a gauge. When it has gone hard under the thumb the glass bottles are carbonated too, and the whole batch goes down to the cellar, where the cold stops the yeast doing anything further. It is a crude instrument, and it is the most useful thing in the cupboard.
iv.
Clearing, pouring and what the log asks for next
A bottle-conditioned cider always has a thin layer of yeast at the bottom, because the yeast that made the fizz has to go somewhere. The bottles are stored upright so that it settles in one place, and they are poured in one smooth movement into a jug, stopping when the sediment reaches the neck. It is not harmful, just cloudy and slightly bitter. The neighbours who prefer their cider bright have learned to leave the last centimetre, and the ones who do not care drink it anyway.
The 2025 batches were bottled in April and May of this year with no trouble at all, and the log now has a single page at the front titled Before You Bottle, which lists the checks in order. The question for this autumn is whether the wild batches can be bottle-conditioned as reliably as the cultured ones. Wild yeast is less predictable about when it stops, and the burst bottles of 2024 were a cultured batch. That page at the front of the log is going to get longer before it gets shorter.
Figures on this page were copied out of the paper log, where they were written with the hydrometer still floating in the jar. Nothing here is advice for anyone else's cellar. Last amended 13 Sept 2026.
