Hi Nicola. When did you pitch the yeast? Normally cider is bright and clear. Yours looks as though it is still fermenting. It can take months to clear and you would be racking the cider every two or three months so that it was a) not sitting on any gross lees (sediment) and you were helping to remove the CO2 that is saturating the liquid, keeping in suspension particles of fruit and yeast cells that would otherwise have dropped to the floor of your fermenter.
