O'Leary Walker Wines was established in 2000 by winemakers David O'Leary and Nick Walker. With over twenty five years experience and established reputations making premium wine with the big companies, these two long time friends decided to take control of their own destiny and craft small batches of wine from some of the best vineyard sites in South Australia. With a great leap of faith they are now doing exactly what they set out to.  

Oh my. How good is this? This is the essence of Polish Hill River Riesling: the concentration of fruit, the depth, the texture, the spice, the quiet power. It’s all here. Just released and ready to be savoured and enjoyed. Jasmine, bergamot, citrus, grapefruit, a sprinkle of rosemary and white pepper aromas. How intriguing are those spices! Grown under organic methods, it brings extraordinary depth of citrus (grapefruit, Meyer lemon), green apple and lime zest married to an equally impressive depth of background spice, including earthy ginger and a light shake of white pepper. Acidity is well-honed with a mineral clean edge. This is what Polish Hill River Riesling is all about. Date: September 2023; Drink: 2023-2037; Price: $30.00; Rating: 96 Points; Jeni Port

Very intense and generous bouquet of mixed flowers, super-fragrant and scented, the palate likewise intense and bracingly dry with a touch of tannin augmenting the mouth-watering dryness. It's almost searingly crisp and intense, rapier-sharp and long-lasting. Quartzy mineral nuances. Very long carry. It will richly reward cellaring. Rating: 96 Points; Huon Hooke; The Real Review

Why is Riesling the best value wine in Australia? Crack this for $30 and you'll sit bolt upright. What a blistering wine we have here! So aromatic and so steely, all the best bits of a quality Riesling are here in a very tidy package. Bath salts, white flowers, Bickford's lime cordial and lemon juice reach for your favour along with a flicker of grapefruit. Green apple peel slides in late and right on cue. Like the Watervale, the shimmer of soft spices comes late but the citrusy tang is real. The expected river stone minerality and chalk feels arrive on cue to close. It's absolutely delicious and I just want more. Drink now to embrace the freshness but this will age beautifully. Rating: 96 Points; Steve Leszczynski; QWine Reviews 

A superb Clare vintage, yet again, with a long and cool growing season. The vineyards, located next to each other, have been certified as organic since 2010. Gleaming pale yellow, there are strong citrus notes here. Lemons, limes and grapefruits, along with a gentle spicy touch and backed by cool river stones. This is finely balanced, focused and with such impressive length. A line of acidity runs the length. This can be enjoyed over the next ten to fifteen years, but well cellared, could go twenty to thirty. A stunning Riesling and simply extraordinary value. Buy it by the case.

Mineral-savoury start with wet stones, flint, brown limes and sage. Flavours are a pleasant continuation, full and round, filled with fleshy nectarines and pears in the middle, slightly grilled. Grapefruit finish with a dusting of pepper and nutmeg spice. I really enjoy the structure and texture of this wine, it has weight and detail. Feels like a whole wine, with front middle and back, confident and very well made. It’s a great deal of satisfaction. Rating: 95 Points; Campbell Mattinson 

What a ripper drink! This delivers drinkability and charm in spades. Green apple, lime juice, a touch of gingery spice, some lanolin and candlewax scents and flavours. Texture, well, waxy too, delightfully so with chewy, chompy puckering things going on around the inherent juiciness of young Riesling. It feels super-approachable and immediately appealing, well resolved for drinking in its youthful flourish. A cracking release. Rating: 94 Points; Halliday Wine Companion 

This multi-layered Polish Hill Riesling from the excellent 2023 vintage shows a powerful and composed core of aromas with classic lime and spice joined by some more exotic nectarine and mandarin skin in the background. This is unexpected texture to the wine, almost creamy layers of focused flavour, well supported by angular acidity. A bit adolescent right now so definitely needs time to come together.
