Rocks for shocks: geologists don’t “debunk” terroir; minerality questioned

Many geologists object to two things: misusing “minerality” and being misquoted.
Site reader and distributor Damien Casten sent in an AP story (with no byline) yesterday entitled “Geologists debunk soil impact on wine at Ore. talk.” The Oregon event was a special session at the annual conference of the Geological Society of America.
At the meeting, Alex Maltman presented a paper with this to say about minerality: “The widely cited direct, literal connection between vineyard geology and wine taste seems scientifically impossible. Whatever “minerality” in wine is, it is not the taste of vineyard minerals.” He calls any perceived connection a “romantic myth.”
Fair enough, there may not be a transfer of minerals from substrate to the glass, but is terroir debunked? Not quite, argued Jonathan Swinchatt in a paper that cites the indirect influences of drainage, accessibility to water, microbiology, soil temperature, and trace element chemistry. He argued that unraveling these links is “devilishly” complex and thus “the connections between geology and wine will remain elusive for some time to come.”
Terroir: clear as mud!
After the jump, Greg Jones, a climatologist from Southern Oregon University (and son of the founder of Abacela Vineyards and Winery in Roseburg, OR) chimes in with his thoughts from the conference and the reporting of it. Read more…

The thrust of the presentation, however, was the unveiling of a “uniquely designed decanter” by Riedel for Charles Heidsieck. The “organic lyre ‘U’ shape” is handmade and mouth-blown and bears a striking resemblance to the “Amadeo” Riedel decanter with a Charles Heidsieck badge. A bottle of the Charles Heidsieck Blanc des Millenaires 1995, a lovely wine, comes with the decanter in a presentation box for $600.
