Time Out says
For a couple of bucks, you can tour Australia's only sake factory
Found on an industrial estate by the Nepean River is Australia’s only sake brewery. Sun Masamune is the offspring of parent company Konishi, who have been making sake in Japan since 1550. For a couple of gold coins, you can visit the sake factory, sample the Go-Shu brand of rice wine that they make on site, and tour the supremely clean and tidy factory floor. Tours are by appointment only, however you can drop into the cellar door at any time. They sell all the Go-Shu (meaning Australian sake) in the store, plus a number of skin products made with from the bi-products of brewing rice wine – which is said to contain 19 types of amino acids, vitamins, polysaccharides and minerals.
