The changes, being made to cement the cider brand's position as market leader, will see a new ad strategy devised by Leo Burnett.
Revamped packaging for both bottles and cans will be introduced ahead of the summer to help the brand communicate its credentials as a premium cider.
The relaunch will be backed by TV, press and poster ads using the strapline 'Trust your tastebuds'.
A major sampling campaign will aim to reach 1m consumers. The brand is hoping that the activity during the key summer months will lure new drinkers to the category, as well as increase the frequency of purchase of existing drinkers.
Further marketing activity this year will revolve around a programme of events that will run in the on- and off-trade at key seasonal times.
The revamp follows increased sector activity, including a number of product relaunches and innovations.
Last year Blackthorn Cider repositioned as a premium brand, competing directly with Strongbow. The Scottish Courage brand intends to challenge this with innovation across its cider range later this year.
Strongbow had a 32% value market share in the year to 1 January, according to Nielsen Scantrack, ahead of Blackthorn.
