The castle, set on the banks of the River Spey in Morahy, is offering a free bottle of its Apple & Pear cider in exchange for 7kg of fruit.
Anybody with spare apples or pears from their gardens, or those with large orchards that have surplus fruit, are being encouraged to bring them to the castle's shop over the next fortnight to top up those picked from the eight acre Walled Garden, which contains 250 espaliered fruit trees.
Angus Gordon Lennox of Gordon Castle said: "Our cider is one of our best sellers and we need more apples and pears to keep up with the demand, which is a fortunate position to be in.
"Everything we make here at Gordon Castle Scotland is created using ingredients either from our own Walled Garden or the local area, so using locally grown fruit from across the North East in our cider means we are staying true to that provenance. The North East of Scotland is not known for its cider, perhaps we can change that."
