I have been working in the wine sector for 8 years and I believe this is the most instructive and well explained content I have bumped into with relation to how soil types impact in wine style. Well done man !

Really interesting video. I’ll look into the Szabo book. Could you recommend any other further reading regarding geology and wine?

Thank you very much Jimmy, I found this topic very interesting and particularly well explained. So, a volcanic soil could be very fertile, but the fertility is "locked" within the rocks. Thus erosion by weather factors, like wind and rain, is necessary to make those nutrients available to the vine. If we apply the same erosion influence but for a much longer time, is it correct to presume that particularly old mountain range could be so weathered by the elements to a point that they will lack fertility as nutrients have been washed away and therefore this might be a decisive factor in producing higher quality grapes? For example, Chile, Coastal Range Vs Andes? Thank you very much!

I am watching this video as part of my WSET3 revision, and despite the fact that this is more aimed at L4 it is really interesting, maybe L4 next!😱

Same here. Although it no requirement to study this matter, it gives a lot of more insights which facilitates the L3 study! Thanks Jimmy

Excellent video as always! VERY informative and well organised! A question about minerality. I recently enjoyed a bottle of El Lance 7 Fuentes from Suertes del Marqués in the Valle de la Orotava , Canary Islands. Overwhelming sulfur aroma that needed several minutes before it settled down. If that aroma isn’t coming from the grapes absorbing from the soil, it is added during maceration or aging? Thanks for your reply!

@WineWithJimmy Жыл бұрын

Hey there Tom, thanks for this interesting question! Sulfur is used widely in vineyards and wineries, at almost all stages of processing - including during maceration and ageing. Added sulfur can technically carry over and be noticed in the final wine, but this is rare. Yeasts also produce some sulfur dioxide as part of the fermentation process (which is why wines can be labelled saying 'contains sulphites/sulfites' even if no sulfur has been added in processing, but that's a different conversation). What you are describing here sounds a bit like sulfur reduction - volatile sulfides. Reduction is sometimes classed as a wine fault, but certain winemakers like to harness the 'struck match' feature of this reaction - perhaps the case here. I know these wines are particularly prone to reduction so you've identified a defining feature.

Love your videos you have great energy when explaining it. As you mentioned J.Szabo’s book can you recommend any other books must have or you found helpful when you where studying Level 3 / level 4. Would be cool a little review on the books you think is useful to read Thank you

Hi Mariya - well, I studied my L3 twenty years ago, and L4 shortly after that... so books have changed. All of Jamie Goode's 'Wine Science' books are a must (and his faults book Flawless). Maltman's Vineyards, Rocks and Soils for Geology. Christy Campbell's Phylloxera. And there are many more - I shall start to plan a book reading list for L4

Thank you for the profound explanation on soil. A question that Calcium is Akaline, isn't it? You mean it will make more acidic wine? I am a bit confused here. Thankyou.

@WineWithJimmy Жыл бұрын

Yes, exactly - Ca is alkaline - this aids the vine's metabolism and it enables the fruit to produce greater acids

@junghwaaubert7079 Жыл бұрын

@@WineWithJimmy Thank you for your prompt reply.. if i may, can i ask how this metabolism works? Furthermore, in Beaujolais pink granite is acidic soil and because of that, I suppose the grapes contain good acidity.. I wonder my reasoning is supporting. Thank you..

hey Jimmy, i see loads of people mentioning the roots of vines are urged to go deeper in/on certain types of soil if the soil have good drainage. why this happens? :

@WineWithJimmy Жыл бұрын

Hi, It's purely because the vines need to look deeper to find the water they need. Good drainage means that the water is not available at the surface. This can also lead to the vine being more resilient in times of drought
