The £30,000 off-trade exclusive promotion will run on 50,000 bottles over the Easter period.
The neck collar offer will give Three Barrels consumers the chance to redeem vouchers in 19,000 stores through highstreetvoucher.com.
There are 100 first prices of £100, with 400 £25 vouchers also being given away.
Tokens worth £1 off a future purchase of Three Barrels will be given to 5,000 consumers.
Brand manager Harriet Knight said: “This is a way for us to give something back to our loyal consumers and thank them for their continued support of the brand.
“We have a number of initiatives planned for 2009 designed to drive trial.”
These include a direct mail campaign targeting a younger audience of 40- to 65-year-olds.
