And at the end of the day the three finalists for the title were declared - and it came down to Sileni Estate, Black Barn and Junction Wines.
Sileni Estate picked up the title in 2012 and 2013 and are eyeing up making it a hat-trick. Black Barn was among the finalists last year and will be looking to step up a place.
Teams comprising two staff from each winery - including a cellar door representative - competed in three quickfire challenges designed to test their wine skills, knowledge and service experience to the public.
The third of the challenges, the "outdoor cellar door", required the teams to establish their own mini cellar door and provide wine tastings, with the public voting on the winery that provides the best experience.
At the end of the Cellar Door Challenge the top three winery teams were chosen and are now in the running for the title to be announced at the awards evening.
