Chemist here. Vibrations would create a mild convection, which helps compounds come into appropriate contact with each other for reaction. This would likely have a similar effect as a mild temperature increase. As for the effect of agitating the sediment, that depends on whether there are any more compounds to extract from it, or if there are any surface-mediated reactions (i.e. catalysis, which could speed up certain reactions).

[@jensastrup1940]

A long time ago, we had bought two cases of decent Bordeaux that were clearly too young (seen in hindsight). As we didn’t have space for them, I put them in the bottom of a closet on the top floor of our apartment, where it gets very hot in summer. After a couple of years, we decided to give them another try, and now they tasted very nice. Despite having been subjected to varying temps. Interesting to learn that the concern about vibrations and moisture doesn’t have solid documentation. That makes getting a wine fridge in our apartment make more sense …

[@baggrabb]

Just found this. I saw other comments expressing curiosity about longer term impacts on the wine, but this did a good job of dialing down the prevailing rhetoric on at least the immediacy of the impact of temperature on wine. Assume once the seal is broken long term storage is at high risk. Thanks, have learned so much from your channel!

[@anselashby2036]

Winemaker here - this is totally anecdotal, but I think the issue with heat / cold is more an issue of oxidation. You point out that as wine expands and contracts air is pushed in and out of the bottle. Repeat that a few times, and you'll have prematurely oxidised the wine (basically creating the same conditions as if the wine were open). I've found, generally, that wine stored under screw-cap (and thus unable to have air push in/out of the bottle during expansion & contraction) holds up much much better to heat, even multiple heat events and/or extreme events.

[@KonstantinBaumMasterofWine]

Interesting!

[@جورجبوش-ص8ح]

We have one cellar under our house in the countryside, which is carved in stone, over 300 years old, with the constant temperature of 13 degrees Celsius all over the year, I also have a cellar in a apartment building from 19th century, where the temperature in winter drops to 16 degrees, in summer in the hottest periods gets up to 20. The room is dark and less humid than the room in the old house. I have stored wine from same vintage and domaines in both cellars for years and I cannot tell any difference in aging. The longest I have stored wine in those is 21 years for some Grand Crus. No difference there so far I could taste or smell. As far as freezing cold or temperatures above 35 degrees Celsius, I did experience Burgundy wine to flatten and die after being frozen, and the same when it was cooked. Since I almost exclusively drink Pinot Noir from Burgundy or Germany, I could not tell how other wines would behave. Pinot Noir for me does seem fragile when it comes to weather conditions.

I experience the impacts of less than ideal conditions with wines left to age. They can die before they are bien a point.

[@DM-kv9kj]

@@KonstantinBaumMasterofWine Yeah, I imagine long-term storage and aging of a decent wine would show much greater difference between a bottle stored at a good, consistent temperature compared with the same wine stored for years in often wildly fluctuating temps.

wow I really didn't expect this, have you already done the longer experiment? I'm very curious about this.

[@francis7064]

I was a whisky geek before seriously getting into wine and can confidently say there is no need for humidity in storing wines so long as cork bottles are laid flat. Whisky is stored upright as the high alcohol will eat away the cork if left in contact with the liquid, I’ve opened 20-30 year old bottles where even tho very dry the cork has still kept the bottle sealed. So long as there’s nothing wrong with the cork and the wine is stored flat then there should be no need to worry about humidity levels.

[@QualeQualeson]

On the topic of vibration, the Norwegian Wine Monopoly did some inhouse testing. They stored wine bottles in a contraption that vibrated quite heavily for a year or two (I can't remember the exact details) and then did a tasting. They couldn't tell the difference. For what it's worth.

[@michaelosborne9279]

Grew up in Trinidad in the 80s. Wine was a lottery my parents found. You could get California stuff being sold off cheap 'because it was old'. But then again a lot of it sat on the docks for uncertain periods in the Caribbean sun and got cooked to death.

Super interesting video with a surprising end, honestly. As a person who works in a retail outlet, I have sent back bottles that were physically warm/with the cork expanded because I just don't want to take the risk with clients. But temperature is one of the reasons why I haven't really invested in a wine collection of my own yet as I live in a warm country (Malta)

[@ericthompson3255]

This comes as a relief to me, as my apartment can get quite warm in the summer. haha. My wines are all in my closet, which stays relatively close to 20 Celsius year round. Maybe slightly over, or under at some points. I've tested the wines myself after some temperature fluctuations, and they all seem to be holding up., but it's nice to see a Master of wine come to a similar conclusion as myself. Haha! Probably not the best for long term, but that's not the plan with most of them anyway.

[@aagguujjaa]

I have found that inexpensive wine bought close to the source tastes delicious, as opposed to wine bought here in the US, where you may pay $20 or $30 USD and the wine taste like a cheaper wine. I always blamed travel stress. But I am glad to have my preconceptions challenged.

[@justifiedreasoning]

Loved this one. Makes me feel a bit less worried about storage conditions at the store or at home for a short period of time. I imagine over 10 years, extreme heat or cold conditions will affect it negatively. However, in the time that wine is usually consumed-- not so much.

[@ChaosCrischen]

My cellar has 15°C in winter and 22°C in summer, but very low daily fluctuations. I haven't tasted any bad influence yet so I am happy with that conditions.

Hello Konstantin. I am a physics professor from Rio de Janeiro. Ultrasonic vibrations are used in chemical labs to accelerate chemical reactions and to clean surfaces. For example, to clean a small piece of metal from microscopic dirt, one might put it into acetone and vibrate with ultrasound. Of course, vibrations accelerate chemical reactions (although much less as a significant rise in temperature). Thus, I would be surprised if vibrations had no effect at all.

[@KonstantinBaumMasterofWine]

That is interesting. Would you say that "normal" vibrations in your home like the vibration of the fridge or your steps on stairs would have an impact on the speed of reactions? I should try aging wine with ultrasonic vibrations though ...

My understanding is that other than the physical bottle damage you won’t notice bad storage temps (particularly heat) for 6 months. The claim is that heat kills the aging capacity of the wine and/or/because it messes up the oxidation trajectory completely

I will have to do a long term experiment.

[@callmeacab]

This is so interesting because I live in an apartment in a fairly hot climate with only a small window air conditioner unit.

I think it would be interesting to see a variation where you run the same experiment over a longer duration of time to see how it affects how the wine ages over time. For example you keep one bottle at a temperature above recommended cellar temp, one way below and one normal. Come back after a year and see if they developed differently.

Very interesting and worthwhile experiment. It’s something that I worry about - perhaps too much. I was slightly surprised when I travelled around Tuscany recently to find that no restaurants that I visited were in the slightest bit concerned about storing and serving red wine at room temperature, which might have been more than 30 degrees. While the wines I drank didn’t taste as good as they could’ve done if served a bit cooler, I didn’t taste any that seemed ‘cooked’. As you and at least one other commenter has said, there’s not a lot written about it apart from the oft-repeated advice, with little data to support recommendations. I would think that the industry would be desperate to learn more.

[@nevim007]

I once put a bottle of pinot grigio into the freezer to cool it down quickly but then forgot about it. The next day the wine was completely frozen. I let it melt and tried a sip but it was exactly as you said - no aroma and totally weird taste.

[@comesahorseman]

When I buy, I try to remember to check the bottom of the capsule; if you see dry or sticky residue there, 😳, assume that either the cork is leaky or the bottle was heated somewhere which pushed wine around the cork. (This tip courtesy of my wine sensei, the late Dave Banker. Thanks, Dave!)

[@bor4oborisov]

Interesting experiment. I think bad conditions can change or damage the wine in long term, probably after months. For several days during transport probably not because the wine is cold and hot stabilised. I think that low protein white wine can survive transport heat without hot stabilisation. My first white wine wasn't heat stabilised and survived a weekend on wild camping on the beach, although some of the corks were starting to poup up. Because of this test I don't use bentonite for hot stabilisation in my wines.

[@KonstantinBaumMasterofWine]

[@angusmcmillan8981]

Very interesting, thanks. Not surprised about the frozen one as I’ve heard several merchants say they’ve sold wines stored for years in freezing Scottish cellars and they’ve been excellent. Regarding heat I’d be more interested in much longer term storage, say five or ten years. Has anyone done a proper control - one case in ‘perfect’ cellar conditions, the other in centrally heated living space?

[@EadricRicmund]

I think the quality of the wine plays a part of it too. There are some wines when left open for multiple weeks from oxidation and will still be drinkable while others, after opening and stored the same way, will quickly taste super oxidized.

[@kengillman5805]

We live in the tropics and our cellar is at 17c. Wine shipped in summer does not come to harm (I check temperature on delivery) and is rarely over 28c. Could you repeat with more delicate white wines - our prediction is that they will be ok, but how hot and for how long?

[@MakingaStink]

I think the hot/cold ones if the cork was pushed out a bit might age poorly and show oxidation over a longer period of time. I find that the most common flaw I come across is actually oxidation, which could be improper storage temps?

[@ciszaxyz4991]

whenever I'm thinking about the vibrations from the fridge I'm wondering if this might even be beneficial? I mean, the underwater maturing of the wine is said to profit from the gentle, constant underwater streams influencing the wine positively. The streams are anyway chosen to be gentle, stable and constant. Kind of like the fridge's vibration, but in a macro? Just a free-thinking ;-)

Great video- and one that is very reassuring; I'm always worried that summer heat/winter cold might ruin wine that is delivered to my home here in the NorthEast United States.

What a great topic! Coincidentally I was on holiday in the south of France 3 weeks ago and had an interesting conversation with one one the wine makers on a Château. We talked about the impact of heat and movement on wine during transportation. He said that if one buys a box of wine at the château and takes it home in his own car the impact will be dramatically less than if you buy it in a store. His argument: a typical delivery by truck takes way longer with stopovers, reloading/transhipping etc. and the wine maybe even has to be transported from central warehouses to the stores. So the risk of temperatures is even higher. On the other hand the wine bottles we usually buy are from local stores. So this whole thing seems not to be a big issue. Question: my father in law always argues with me that after transportation the wine should rest for a couple of weeks as the shaking and movement effects the taste. What do you think of "hard shaking"? Maybe another topic for a video? Thanks again und liebe Grüße 😉

[@mauriziopolistina6019]

You make valuable contents in an industry all too often devoted to fashions and status. Keep going! About the topic: Vibrations might be a problem because tiny amount of gas can flow in and out, causing oxidation. We are not talking about your fridge vibrations, but somethinf like having your cellar close to a subway or a train station. Heat in my experience has a tremendous impact on aging potential, but you won't spot any difference before 5 years at least. I think that a quality wine can last a few years regardless of where and how it has been stored. Many important wineries ( such as montevertine, san giusto or burlotto) release their products in spring where, at least in italy where i live, temperature can be really high. Every single bottle they sell face high temperatures for a short period of time during transportation. If this would be a big issue their wine would not last long, which they do. Therefore we can safely say that is a problem only after a long period of exposure. Wine is tough man!

[@KonstantinBaumMasterofWine]

Yes, I need to look at the long term impact of temperature.

[@mikeappolo306]

Try this experiment with white wines. The difference between the normal and hot wine will be extreme. Also, try to find a red producer who doesn’t use bentonite. Bentonite mitigates the heat exposure. Heated / bentonite free Chardonnay takes on a cooked apricot flavor often. As a winemaker, I would not expect the frozen wine to taste much different. We cold stabilize all white and Rosé wines to mitigate low temperatures. Otherwise, you would see tartrates in the bottle - even if left in a fridge for a few days.

Love the experiment! It is possible that the bad treatment only lasted a short time. My experience is that when storing wine at a higher temperature, the wine does age faster. Not sure if it's exactly 10 degree higher that "doubles" the maturity though.

[@KonstantinBaumMasterofWine]

Thanks. The speed of chemical reactions doubles but that does not mean that the wine ages twice as fast.

[@Birdylockso]

@@KonstantinBaumMasterofWine Thanks, I am also currently testing storing a wine upright vs. laying down, then see what the difference might be after 5 or 7 years later. So far, it's been 2 years. (I should have placed bottles to test after 2, 4, 6 years, etc.) Supposedly, the wine storing upright would have its cork dried up and causing bad stuff to enter the wine. But, wouldn't the vapor pressure within the bottle neck keep the cork moist anyway? Or, maybe the moisture just enough for the fungus to develop inside the bottle? Anyway, a small price to pay for science... Please do let me know if you or others have already conducted the experiment and have the result already.

This is really surprising. I've had a few bottles over the years that were cooked in transit and were totally maderized--the palate and bouquet were filled with pruny, raisiny, stewed notes; it totally ruined the wine.

[@bbranco010]

Very original idea! Great video. As others mentioned, it would be great to see this with white wine as well. Also, is that a Riedel Performance Syrah glass you used?

[@KonstantinBaumMasterofWine]

Thanks. I will do another experiment on this topic. The glasses were the Riedel Veritas Champagne glasses. I use them often as my universal tasting glasses.

[@dwongst]

Thank you for an excellent video! I have read an anecdotal report that out of a case of wine left in the back of the car in the summer heat, some (most?) bottles were completely unaffected while the rest tasted bad. Could you maybe repeat the experiment with a larger sample?

[@KonstantinBaumMasterofWine]

Good idea

[@andreasjunge2144]

So, if that's the case... I have a wine fridge where I keep red wine in the 30 to 60 Euro range (mostly Rioja Gran Reserva and Barolo). Room temperature in my cellar varies between roughly 16 and 22 degrees from winter to summer, and it's dark. Do you think I should just get rid of the fridge and buy more wine? (If you answer, thanks for your time. Last time you answered I followed your advice and bought a Coravin and it's killer!)

[@KonstantinBaumMasterofWine]

That is quite a range. If you want to store the wines long term the wine fridge might be useful. Glad you like the Coravin

[@andreasjunge2144]

@@KonstantinBaumMasterofWine 😂 Define "long" and "might be" 😂. No, seriously, thank you, I love just sorting through the fridge once in a while and finding gems I'd almost forgotten about.

Could it be that younger wines can take more suffering than aged wines in the short term? I definitely wouldn't want to do the test on a bottle aged for 15, 20 years, it would be too much pain and sacrifice 😂 What I accidentally did was keeping a 2001 Chateauneuf du Pape under my bed for a few months cause I ran out of space in the wine fridge and we had a week-long heatwave last month (~30C in London). When I remembered about the bottle and checked it, the cork was slightly pushed out. On an urgency procedure I readily opened the bottle and to my surprise it still was reasonably fruity and I barely could notice any oxidation. Back in Brazil many years ago when I had no wine fridge over there I do remember of keeping an entry-level Cote du Rhone in ambient temperature (that'd be an average of 25C) for 3 months. I had previously drank the same label/vintage/shop straight from the shelf which was fresh and good. The stored wine was definitely ruined after those 3 months.

Very interesting experiment. The effects may be over more time - ie a year of up and down temps. But since there is no real science it is hard to tell. I would like to see you do the same experiment with a Riesling to see how the aromatics may be affected if at all. Love the channel. Keep it up!

[@KonstantinBaumMasterofWine]

Thank you! I will do a long term experiment.

[@carlcadregari7768]

Great video. Would you mind Doing the same experiment with an aromatic white? 😁

[@KonstantinBaumMasterofWine]

I will do that!

[@ol4513]

Very interesting results! Do you think it is a major concern to store wines long term in a cellar where the hottest days would just reach 23C?

[@KonstantinBaumMasterofWine]

I think the fluctuation of the temperature has an impact but it really depends on how long you want to store the wines.

[@enologando]

Really interesting video, with surprising result as well! A couple of years ago we sent some bottles of Vermentino to a wine fair, and the bottles that were unsold came back with new notes of hydrocarbon, almost rieslinglike. Maybe the whites doesen't tolerate the heat as well as the reds

[@KonstantinBaumMasterofWine]

This might be true. I will run another experiment on that.

[@methree2242]

@@KonstantinBaumMasterofWine Loved the video, thanks!! You've already mentioned that you might run a long-term experiment - it would be cool to see what happens to wines stored at a changing room temperature on a wine rack in a kitchen for a few months (typical problem for average wine drinkers) compared to wines stored at constant cellar temperature. And even more so if the wine is already aged. Older wine might be more fragile?

[@scottcurtis5322]

What makes you say the temperature should not fluctuation a lot. Like 8 to 18 each day, night. What negative effect does this have

[@scottcurtis5322]

It may do the wine some good, or at least bring forward the day of drinking

[@melsialiaj]

Maybe a prolonged cooking test should be done. 1 to 2 years!?

[@kktan331]

this is great! @konstantinbaum could you do this extreme temperature test, then keep it for a few weeks/months before tasting?

[@KonstantinBaumMasterofWine]

Will do!

[@christiaanleussink9340]

Dear Konstantin, thanks definitely very interesting. I wonder, do you think this result may vary depending on red/white, grape variety, wood-aging, for example?

[@EricZeak]

I was very surprised by your results. I would've thought the extreme temperatures would have been noticeable. I always thought it was a concern because people talk about that all the time. One time I had a wine that spent a whole summer around 90F and I thought it tasted "cooked."

[@KonstantinBaumMasterofWine]

I will have to run a long term trial.

[@matteomelfa]

Interesting... I am surprised as well, the question is... Could it be, being an average Côte d Rhône, that maybe the higher level of SO2 may protect to a certain extent/for a certain time? If so, a less SO2 wine should be much more fragile, and perhaps we could notice much more difference? What do you think Teacher?

[@KonstantinBaumMasterofWine]

I agree. The CdR was pretty stable so I need to make another trial with different styles of wine.
