Scottish Secretary Alistair Carmichael said that there was a "sympathetic ear" to the call in the Treasury.
Campaigners want ministers to scrap the so-called "escalator" on whisky, which automatically increases duty by 2% above inflation.
It follows the abolition of similar price hike on beer.
The Scotch Whisky Association estimates excise duty and VAT make up 79% of the price of a bottle of Scotch.
Mr Carmichael said: "You will see what happens with whisky duty come the Budget."
Last week, Nicky Morgan, economic secretary to the Treasury, said she would give the call "very serious consideration".
