Leeuwin Estate 2008 Art Series Riesling (4.5* $22) After a couple of younger Rieslings from other regions where the citrus notes were far more pronounced the relatively restrained nose and the semi-aged notes across the palate (that hydrocarbon element's there again, but lurking below the surface rather than muscling its way to prominence) made a rather pleasant change. In the mouth it sat comfortably in between the citrusy zing of a young Riesling and the overt developed characters you find in the aged versions. There's a tendency to see that transition from youth to maturity as leaving a void that detracts from the drinking experience, but there was, I thought, plenty going on here. Thankfully, there's still another bottle to go.

Olssens of Watervale 2006 The Second Six (4.5/5 $28) Deeply red in the glass, with complex notes across the nose and an acrobatic balance of red and black fruits across the palate this doesn't pack quite the same punch as its sibling but comes across as well weighted with a pleasing depth of flavour and a lengthy finish which, again, encourages the drinker to take some time over the end of the bottle.

Pfeiffer 2010 Winemaker’s Selection Viognier (4* $25 C2 $22.50) My research notes suggest that when the grower gets it right deep yellow grapes produce wine high in alcohol with a strong perfume. While 13.2% isn't all that high, the aromatics were definitely there on the nose (peaches and stone fruits, touch of spice) with the apricots coming out across the palate. This Wine Club only number, nicely textured and hitting the right spot when it came to accompanying my favourite roast chook could, once again have been rounded up, but one suspects it'll be all gone by the time the Gamay order goes in.

Stella Bella 2006 Suckfizzle Sauvignon Blanc Semillon (4.5* $36) Plenty happening on the nose, herbs, grass, berries and talc, with the interaction between Semillon, Sauvignon Blanc and oak delivering a complexity across the palate with layers to savour over a lengthy sitting. Won't be waiting too long to open the other bottle on hand and definitely one to throw in the next order from Stella Bella.

Tahbilk 2006 Riesling (4.5* $n/a) Pale straw in the glass, and from the first sniff there was the familiar petrol notes that you come to expect in quality mature Riesling and the same notes came across when the wine hit the palate. Not, perhaps, in the same bracket as mature examples from premium growers in more highly rated regions, but mature Riesling of this quality at this price point (a notional $12.50 as part of a vertical half-dozen) and this quality underlines extreme value on offer if you know where to look.
