Description Conditions for grape growing in Langhorne Creek are ideal thanks to the natural fertility of the floodplain soils, the ability of those soils to retain moisture from natural winter floods, and the moderation of the local climate by cooling evening breezes off nearby Lake Alexandrina and the Southern Ocean in summer. Fragrant honeydew melon, white peach, fleshy mango and pineapple, with lively acid on the back palate and just a touch of creamy oak. It’s a beautiful match to roast chicken with all the trimmings.
