Cellar door tastings will remain off limits and have not been allowed since March.
Wine Victoria chair Angie Bradbury said cellar doors are essential to regional tourism.
"Cellar doors are the lifeblood of the Victorian wine industry," Ms Bradbury said.
Winemaker Tony Winspear said Balgownie Estate's Maiden Gully cellar door tastings are crucial.
Cellar door tastings are not permitted under the state government's COVID-19 guidelines.
From June 1, restaurants, cafes and other hospitality businesses that offer table service will be able to serve food to up to 20 guests.
Tahblik Winery's Neil Larson said a healthy wine club membership has helped insulate it from a catastrophic sales decline.
"Our wine club has bumped up since the pandemic started," Mr Larson said.
The absence of cellar door tastings is being felt across the industry, according to Mr Larson, a 29-year industry veteran.
"For a lot of smaller wineries, cellar door sales and their hospitality offerings make up most of their business," he said.
Mr Larson is a member of a steering committee to support Victorian winemakers and wine grape growers affected by the recent bushfires.
Almost $1 million has been pledged by the state government, with the committee including representatives from government, industry and Wine Australia.
The program will include online technical workshops on recognising and addressing the effects of smoke exposure, evaluation of 2020 wines by expert sensory panels and access to a benchmarking kit assess their wines.
"We want to make sure winemakers can be sure they're offering the best possible product to Victoria and the world," Minister for Agriculture Jaclyn Symes said.
Wine Victoria chair Angie Bradbury said the program will empower winemakers and grape growers to identify issues with smoke taint.
"Long term, it is going to help us do research about the impact of smoke taint," Ms Bradbury said.
"Everyone says we will have more frequently, harsher bushfires as a feature of our weather patterns.
"Learning about these impacts is important because it is damaging for the industry."
Ms Bradbury said that statewide, there has been a decline of at least 80 per cent in revenue for those in the wine sector.
"Revenue has disappeared since COVID-19," she said.
