Real chalk balances the water supply

The geological controls in Coonawarra

“…Gaps of several centimetres are common, and permeabilities of .1 Darcy are anticipated. Thus the drainage conditions at Coonawarra are ideal for vines and are remarkably similar to those in true chalks, as described by Hancock and Price (1990). The Terra Rossa has a high mass-permeability and will allow any excess rainfall to penetrate the underlying, also highly permeable, limestone.…”

The evolution of wine research

“…At that time of the evolution of organic winemaking, the future that organic, sustainably produced wine would have played upon the demand of today's consumers for organic wine products, and the relationship and importance organically produced grapes would have upon the environment were only beginning to be addressed. Wine chemistry, however, was the predominant focus of the journal's early wine research topics addressing subjects including aperitifs, fruit and dessert wines (Nguyen et al, 1990), minerals and water supply (Hancock and Price, 1990) and chemicals (Fluss et al, 1990).…”

“…Following the global patterns of rapidly growing wine production and consumption, wine research as an academic area of interest began to emerge in the early 1990s with the creation of the Journal of Wine Research. Because of this, scholarly research was initiated by academics primarily representing oenology and specific to areas including chemistry (Hancock and Price, 1990) and winemaking (Fleet, 1990). Subjects related to viticulture soon followed (Smart, 1993), as well as early and sparse appearances in topics related to demographics (Nicolson, 1990), history (Bell, 1993), government (Unwin, 1994) and market segmentation (van Westering, 1994).…”
