Just some food for thought.
Identifying a target audience for this is crucial. I understand you may be a little witheld in the niche of your idea, but Australia is a rather mature and saturated market, the vino has to stand up before the fun and games.
From the perspective of a wine degenerate, I would have no interest in purchasing a pack of third rate local wines. Wine nights are typically a theme, and everyone brings a bottle or two from their extensive collection. Breaking into this market, will require some serious sourcing. South African wine comes to mind, there's some serious valuetown there and a glaring hole in our market with the europeans getting all the hype.
Not sure if you are alluding to a wine club type of model, but this is a play on a specific target audience:
The Borough Box is an evolving monthly collection of sustainable, organic and biodynamic wines from Australia and around the world. Six wines delivered to your door every moth. Currently available for Sydney and Melbourne suburbs only.
theboroughbox.com.au
Exclusivity since it belongs to LoFi importers/distributors, jumping on the natural wines buzz, a younger target market susceptible to influence, and of course the wines are not cheap either $180 for 6 bottles per month.
So, before any financial decisions are made, do consider than we are not an Asian market, a couple of instagram posts and influencer tweets will not cut it here. Our market is relatively small, and the people have been spoiled with choice, long gone are the days where yellow tail visited the dining table. Regardless of what "additional value" your product may bring, the wine still needs to hold up.
TLDR: You can dress up goon in a bottle, still goon.
