The old marketing rule, when you're launching a new brand in a saturated market - "don't try to take a tiny slice of an overcut pie, create a new pie or take a larger slice of an existing one".
You would be better off with a hoppy APA/AAA, a real IPA, a saison, a biere de garde, or a local belgian tripel for goodness' sake. You might stand a chance, then.
Competing with a "nothing special" beer is idiotic. If you can recall, which I'm sure you will, carlton draught's last few campaigns:
"Slow moooooootion" (current campaign);
"Made from beer"
"Flashdance"
"It's a big ad, for Carlton Draught"
You think you're going to compete in the "inoffensive" beer market against that? (I used inverted commas because I still find them offensive, but the vast majority of people find it to be "meh, beer").
What about Corona? There are number of other cheaper beers out there, yet Corona can still exists for $18/6pack (for a beer that costs 50c to make and import) appealing to pretentious beer wannabes. Hell, Sol can't compete adequately, with Wesfarmers (owners of Coles/Liquorland/half the country) and cheaper pricing, why can you?
The fact that you are in Adelaide, means you're competing with the largest "craft" beer maker (coopers) in the country, as well as the fact that the majority of craft beers in this country come from SA/WA. For a city of 1m people, Adelaide's beer market is more flooded with local beers than anyone else, because you can buy coopers anywhere.
Then you have the "sick of beer" onslaught that the kiddie-drinks are continuing to use, in order to erode beer's share of the 4-5% stubbie/can booze market.
The way I see it, you're trying to compete in an overcrowded market, yet alienating the drinkers that might give you a chance of succeeding (real craft beer drinkers). Look at the beers currently occupying "craft" beer headlines, have a taste - these are your real competitors, and if you bring out a "nothing special", they'll kill you (yes, S&W, I'm looking at you).
Not trying to be a hater, seriously not, but I don't think you've thought this through. And real craft brewers and drinkers are probably the only people who will tell you the truth, and if it were me, I'd rather the painful truth, than even more painful financial ruin.
