No Schist Sherlock: How Wine Gets Rocks Wrong

Wine Blast with Susie and Peter

‘From virtually any soil a high-quality wine can be made. The use of geology to promote the quality of a wine is thus merely a marketing tool.’

This is an episode that may ruffle a few feathers.
We speak to two wine-loving geologists, Professor Alex Maltman and Dr Geert-Jan Vis (the latter responsible for the quote above). Both of them raise serious questions about the line the wine world often endorses about how geology (think: limestone, schist, granite) influences wine.
Vis calls the notion that geology and soil influence wine style, ‘romantic b*llocks’. Maltman says it’s, ‘over-hyped’ and writes, ‘simply saying a wine comes from a particular rock doesn’t convey anything about what I might expect from a wine.’
And yet we regularly see wine literature talking about limestone or granite, Kimmeridgian or Jurassic (and so on) and linking this explicitly to wine quality and style.
And this isn’t even to get started on the topic of ‘minerality’ in wine…
So what gives? What’s really going on here? To what extent can geology and soil be seen to impact the vine and wine? Or, to flip it round, to what extent do experts think that the role of geology and soil is over-rated and misunderstood when it comes to wine?
It’s important to say we’re not being deliberately controversial or trying to undermine the concept of terroir (the notion that specific places produce wines with specific characteristics).
What we’re doing is asking questions and challenging a set of prevalent assumptions which we feel is…well…questionable.

All details from this episode are on our website: Show notes for Wine Blast S4 E20: No Schist Sherlock - How Wine Gets Rocks Wrong.
This is the first in a loosely-connected series of programmes in which we’ll tackle tricky or controversial issues in wine, from minerality to microbiology and yeasts. All with the aim of provoking informed debate, challenging questionable opinions and seeking clarity above all.
Thanks for tuning in. Here's to the joy of wine - cheers to you!
Ps and if you don’t know what petrichor is – we’ve got the answer…
