Mixing up a starter bottle can be a good way to give any new fermentation a headstart.
Take something like a pasteurised milk bottle (ideal as it will accept a bung and airlock) or a 500ml or litre PET bottle, put in about half a pint (or 250ml) of orange juice or grape juice or even water with just a couple of tablespoonfuls of granulated sugar and a pinch of citric acid, add some yeast nutrients, pitch your yeast, fit an airlock or plug with cotton wool and leave it in a warm place for a few hours. This can then be added to a new must.
To restart a stuck fermentation or get a troublesome wine going (e.g. cordials or Vimto), make up a starter bottle as above. You may need to wash and sterilise a range of bottles, say a pint milk bottle and a 2 litre pop bottle. Give it a good 12 hours to get started.
After that 12 hours, add half a pint (or 250ml) of your stuck or problem must, refit airlock or cotton wool plug, leave in a warm place.
After a further 12-24 hours that should be fermenting nicely, add a pint (or 500ml) of your stuck or problem must, refit airlock or cotton wool plug, leave in a warm place.
After a further 12-24 hours that should be fermenting nicely, add 2 pints (or 1 litre) of your stuck or problem must, refit airlock or cotton wool plug, leave in a warm place.
You should have the idea by now, double, double, double until it's all going.
