I may have to throw in the towel on Coravin.

#1 Post by A.B ud res »

i was an early adopter.. the minute RP posted that original video i got on the waiting list. I thought it was the greatest thing ever. I marked my bottles and went back to them six month later. Still perfect. I was all-in.. then i started realizing that i was having very frequently failures with connecting new gas capsules. The instructions said "hand tight plus a quarter turn" or something like that. I learned the hard way once you "back off" the turn all the gas shoots out in 2 seconds. I'd say i was having about a 1 out of 6 capsules total loss. Oh well, i dealt with it. One time when i was ordering more capsules i said to the woman "yeah it sucks sometimes i lost a whole gas in one shot" looking for an Amazon-like response like "oh that's terrible let me send you a couple for free". But i got crickets.

So anyway. I just pushed down the needle on a 2003 Foley claret and i got dribbles out, that's odd, i could have sworn i put a new capsule in a week ago and hadnt used it much since.. maybe i forgot. So i put a new capsule in (here we go.. crap shoot did i turn it enough?). Looks good. okay i got first glass out. 15 minutes later got second glass out. all good. Came back an hour late for 3rd glass and NADA.. gas totally gone. W.. T.. F.

My device is version 1.0 of this gizmo. Has anybody else had similar functionality issues with the gas? Tonight just iced it for me.. brand new capsule device failure. If they havent made the twisting on of capsules a better/reliable situation i feel like i cannot continue with this device. I dont have complaints about needles or the reliability of what kind of wines can be gassed or not. I just want the darn gas capsule plastic handle to work.

I think the plastic threads get stretched out or warped and to compensate you have to tighten a little harder each time until you hit the point where you can't tighten further and it's not properly seated.

It absolutely sounds like it could be that. great guess. So what do i do? Try to get a freebie new model? I'm really hoping more motivated people from this board have escalated this issue and gotten some sort of result from it. Or am i just the victim of early adoptor. I really dont want to waste another capsule on this thing.

I've had similar experiences. Solved the problem by wrapping one layer of plumber's tape around the threads.

Coravin might be willing to send/sell you a new bottom cup, other than that it's just another example of the imperfections of the device.

Maybe the newer versions don't have the same issues as the original model, which I'm assuming you're using.

We had had the same thing happen with our 1.0 . I thought it was something I was doing but found out otherwise. I contacted Coravin and they informed me I wasn't the first to have issues and they upgraded the cup and would replace mine with a new one and send a couple free replacement cartridges for my troubles. We got the new one and no problems (so far)

I also was an early adopter and had a problem with my capsules immediately emptying. It was apparent it was the device and not the capsules after three in a row failed, so I called Coravin and they sent me a replacement device. The replacement device has not had the issue once. I'd reach out to them to explain it's clearly a device issue and you need a replacement (on them).

Had two devices replaced free by Coravin for similar issues. Looks like the third device is the charm.

I called them this afternoon.. they were extremely cordial, the fessed up design issue. They suggested i try to keep clean the threads where the capsule mates with the base. They are sending the newer designed capsule sleeve and a 3-pack of gas for free.

thank you all so very much for your insight.

I love mine still. Fortunately I haven't had to go through any of the issues others have. One thing that is suggested is to purge the line before using. That would allow you to get an idea of argon flow before puncturing the cork.

I've been experiencing the exact same leakage issues but with the newer Model 2. At the time Coravin Customer Service said they'd send me a new, redesigned capsule cup plus 3 replacement argon capsules to compensate for my loss but they never did...very frustrating! I'm glad I came across this post. It reminded me of something I had almost forgotten about and prompted me to send them another email earlier today to follow up on this unresolved matter. I'll keep you posted on the response I get.

I had a similar issue with Pungo (internal seal leaking) so it's not immune either. That said, the company went out of their way to make me happy. In the end I'm not so big on the dispenser systems and have found that a shot of argon before leaving in the fridge gives me one day of acceptable preservation.

I have had very good luck with the Eurocave Wine Art product. It is greatly improved over the original model. It works very well,and doesn't use any inert gases. It preserves by maintaining a vacuum, using (I think) the technology used in CPAP devices. Cheaper, less hassle, and it works.

My quick google search shows that device starts around $400? Also, I’d be concerned about a device that uses a vacuum with the thought that it’s actively removing volatile aromas before the wine ever gets to your glass.

Find an airtight 375ml container. Fill it up and place it in the fridge. Wine is just as good the next day.

Fridge temps may slow biological spoilage but it will increase the rate of oxidation.

as you all well know, coravins are murderous thieves that thin your cellar by killing bottles you weren't intending to open any time soon. I hate my model 8 and use it several times a week (but haven't had any gas leakage)..

Pouring the wine into the 375ml container will certainly expose it to more oxygen than use of a Coravin (assuming the cork properly re-seals). But why/how does lower temperature increase the rate of chemical reactions, oxidative or otherwise? I always thought lower temps resulted in slower reaction rates, spoilage and oxidation.

I'm with Russ and have refrigerated in 375s for a dozen years or more. I find it very reliable. It's rare that i find an wine shows any oxidation on day 2 ... or 3 or 4 ... unless it was a fairly unstructure wine to begin with (e.g., some grenaches).

We have a model 2 where I work. It's about a year old (I think) and we've recently started having what seems like the opposite problem. The capsule cup is extremely difficult to remove sometimes. No one will own up to over-tightening, so we were thinking that something is going on regarding the gas pressure. This topic is making me think we have no clue.

The lower the temperature the faster a liquid will absorb gas. But as I said, low temperatures can guard against biological spoilage. If you’re drinking that 375 within a week I’m sure you’re fine.

Just a fun piece of winemaking science I’ve picked up along the way. I used to store leftover wines in the fridge but not anymore.

Wow! And your ITB? Yeah, and once those volatile aromas are sucked off, no others will ever be produced. Eventually, the entire bottle will be gone through this evaporation.

Thanks Nolan. Interesting as I’ve anecdotally been less impressed the next day with open bottles left in the fridge vs those left out on the counter. Never did a comparison and figured it was random memory tricks but that might explain it.

I've been sticking 1/2 of a 750 into the fridge most week nights for 20+ years. The rate of oxidation or spoilage or whatever you want to call it tends to be quite slow in the first 24 hour period unless I am dealing with an already mature wine or a very light Grenache or Beaujolais. Younger wines, many of my daily drinkers, and they are just fine.

John, Robert and Russ, I think your full 375 is a different situation than Nolan's or my open or re-corked half-bottle in the fridge.

In your case, the amount of O2 in the bottle is limited to what got in there when you filled the 375. That O2 will be available for oxidation but no additional O2 will enter the bottle. And the cool temps will slow the oxidation reactions.

A half-full bottle, OTOH, has a generous source of O2 floating above the wine and available for ongoing oxidation.

I think it’s also a weird case (like Alan discussing the slow-ox practice) where science and experience offer different (or seemingly different) explanations.

Perhaps you're not taking it out of the fridge early enough and it ends up cooler and showing differently? I generally don't put my leftover reds in the fridge because I never seem to have enough time in advance to let it warm back up to temp I want it.

The oxygen solubility goes up at refrigerator temperatures but the rate at which dissolved oxygen reacts and oxidizes the wine goes down. I think the latter effect is a fair bit larger. You can do an experiment up slicing up an apple or banana and testing whether it browns faster on the counter or in the refrigerator.

Ditto. But I don't wait until I'm done done with the bottle. I know right away whether I'm going to drink the whole bottle or not and pour off half of it immediately on opening. I've never put a partly-filled bottle in the fridge after it's been open for a while. Seems safer just to finish it if you're halfway through and haven't taken precautions. Better safe than sorry.

Quite possible. I’m generally lazy and pay little attention to the next-day remains, as they’re usually a small amount. And the effect is far from consistent. It’s occasional.
