The combined effects of site soil and climate on the vine. The Barossa has some very distinct sub-regions which exhibit their own unique influence on the wine. A journey through the Terroirs is a lesson in the Barossas versatility. We have chosen Eden Valley to highlight its rich, darker flavours unique to this high altitude, cooler climate and rocky, clay loam soils.

Conceived as a white wine development program, the Bin 51 Riesling soon became one of Penfolds' star performers. Eden Valley is an obvious choice of region for Riesling due to the higher altitude and cool climate. The wine offers delicate aromas of fresh cut apples and pears with a twist of lemon and minerality towards the end. A great deal of fruits and acidity makes for an interesting white wine with propensity to age gracefully if carefully cellared.

Displays classic Chardonnay characters of white peach, nectarine and fresh figs. The palate is fresh and vibrant with fruit flavours of citrus and white peach. Maturation in French oak provides subtle nutmeg and clove characters on the palate, while a clean slatey acid backbone provides length and structure to the wine. The wine is complex with no single character dominating the wine. The flavour of the wine persists long after it has left the mouth.

Dopff Riesling Grand Cru Schoenenbourg has quite phenomenal citrus notes with a luscious and toasty caramelised honey element. Beautifully balanced acidity and immense length. Sheer indulgence!

St Hallett Higher Earth Syrah St Halletts Higher Earth Syrah marks a new chapter for a brand known for its bold, unmistakably Barossan Shiraz. This wine, a true Syrah style, is lighter on its toesethereal, evenwith perfume that skips from the glass, and a juicy freshness that calls for drinking, with pleasure, right now. It seeks to represent with purity and grace the high altitude and cool climate of the Eden Valley, a showcase of this unique sub-region.The fruit for Higher Earth comes from parcels in four of St Hallets Eden Valley vineyards. Each parcel is treated individually according to its readiness and maturity. Unlike other St Hallett cuvées, Higher Earth is fermented at cool temperatures to instil vigour and freshness. It is aged in 25% new French oak. The result is a Syrah with lashings of dark fruit flavour and a lick of black pepper spice.

Petaluma Riesling is one of Australia's finest examples of this noble variety. Pale straw in colour the palate exhibits lemon and grapefuit flavours matched by some fresh and racy acidity. Sourced from the home of great Australian Riesling, this trademark Clare Valley aromatic white is wonderful when opened upon release and like all great Rieslings, will develop brilliant toasty characters over a 10 year period in the bottle.

1998 was the fourth successive drought vintage in the Clare Valley. This Riesling has a fuller orange blossom flavour and aroma produced from a drought year.
