Beer
Duckstein Brewerey
The Swan Valley in Perth's outskirts is known for its wine but also makes some decent drops of the amber variety. Duckstein Brewerey is one of the states first micro-brewers and produces a range of German style beers that are particularly popular around Oktoberfest time. You can take a look at their copper brewing kettle and then sample an ale in the garden.
Coffee
A debate about the quality of coffee in WA grumbles on endlessly, with many visitors claiming a decent cup near impossible to find in the west and locals countering that they are just not looking in the right place. Subjective bean preferences aside, it is agreed that coffee is generally more expensive than in Eastern capitals and a higher price averaging $3.80, but up to $4.50 does not necessarily buy you a better cup.
Northbridge, Fremantle, Subicaco, Mount Lawley and the CBD in and around Perth have the highest concentration of cafes where you are more likely to get a decent espresso.
Outside of the metro area it can be hit and miss, but you might improve you chances around Albany and Margaret River where a couple of boutique roasters have operations and coffee sits in the same circles as the gourmet food and wine scene.
Hoochery Distillery
Kununurra in the Kimberley is home to the Hoochery Distillery, the oldest continuously operating rum producer in WA est. 1995, where local cane sugar is used to make some pretty potent booze. Though it's aged in oak barrels it's still a harsh gulp but the high alcohol percentage, up to 70%, hits in the right way. Tours of the distilling operations run in the peak season.
wine
Western Australian viticulture may not produce the large volumes of the wineries on the east of Australia, but the vineyards here are known for producing quality over quantity.
The Margaret River wine region was only established in the late 1960s but has since built a reputation as an eminent producer of premium wines, particularly Chardonnay and Cabernet Sauvignon varieties. Around 90 vineyards have their cellardoor open for tastings and sales, providing plenty of opportunities for serious libations.
Swan Valley in the outskirts of Perth was one of the first places in the old colony where grapes were grown for wine, however it really developed as a wine region in the 1920s when migrant Croatian and Italian families established many of the wineries that still exist today. The valley overflows with a myriad of wine related attractions along the Swan Valley Food and Wine Trail and hosts no less than three festivals a year.
