Never been there myself, but most reports are good. Sells the better Coopers tins too.

Great place, been there twice, use their OneShot and have made 3 of the Masterbrews.

Fairly certain everything else is a Brewcraft, or another store (Hardware, Cooking/Baking/General) that also stocks some brew stuff, ie the one in Gawler. Happy to be proven wrong though.
Personally, I buy basic Coopers/Cascade/Brewiser tins from Supermarkets on special, grain, steriliser, liquid yeasts and some fancy kits from Grumpy's, specialty hops and good dry yeasts from Craftbrewer in QLD, and everything else from the Brewcraft at Reynella, or less often the Brewcraft at Melrose Park.
I find that
- the supermarkets are always cheapest for basic Coopers tins, as much as $2 cheaper than BigW and K Mart at times
- Jovial Monk is the only one in SA, aside from Coopers itself, who sells the Thomas Coopers and Brewmaster Selection tins
- Grumpy's is cheapest for grain
- Craftbrewer is always cheapest for hops, even including postage
- Brewcraft stocks most of the basic items that Supermarkets never will, is very convenient, and is great for stocking up on "boosters", Black Rock tins and other basics a few times a year when I get a specials catalogue in the mail. One of the guys at Reynella is a great guy too, always helping with recipes, beers to try, a few stories as well.
