There is a high Eden Valley and a lower Eden Valley though such terms are just an approximation as Eden Valley is a large wine district with a range of variable topography. In this aspect it is different to the Barossa Valley which is a tight patch work of adjoining vineyards that roll down over gentle slopes and across the broad flat valley floor. The Eden Valley is a tough rocky landscape with poor soils so suitable vineyard land has created small clusters of vines positioned between wide expanses of grazing paddocks with skinny unsuitable soils.
There are some fabulous vineyard clusters and those developed by the Henschke family at Keyneton illustrate the wine quality that can be achieved. The origin of the Burgoyne Shiraz is from the low Eden Valley where the reds are plumper than the far cooler high Eden. Still the low parts of the Eden Valley are one hundred or more metres higher than the Barossa Valley so expect a Shiraz that highlights different flavour aspects.
