How to store bottles with a Stelvin screwcap?

Vertically.

Either way - doesn't matter as far as I've heard. Martin

I think it may very well matter - especially if you stack cases.

Stelvin closures are very good at sealing in the goodies and keeping air out, BUT if the cap gets dented on the crown - particularly at the sealing surface, which would be the crown's edge - all bets are off.

I first observed this weakness in carbonated soda bottles that lost their fizz because the cap had been dented by hard contact with ???.

Best recommendation would be to store the bottles upright, which makes for easy decanting if the wine throws sediment.

Sorry if this looks like rubbish, but I'm having to use google these days thanks to my inexpensive broadband connection having no news server. I dropped out of this for a couple of years as a result (though my almost 2-year old daughter might have a bit more to do with that).

Tom is correct here - damage to the seal around the top will stuff the seal. As a winemaker, I generally prefer screwcaps (and buy accordingly), but this is one of the real issues I have with them compared to cork.

Having said that, we stack them 3 pallets high, with 64 cases to a pallet. So I think that under most static loads they will survive fine. But please protect them from being whacked on the edge. Most new screwcaps are applied with "redraw" which is the additional "step" you see in the top, where the top wad is actually bent over the edge of the bottle. This increases the seal contact area, so they are more resilient than earlier (usually pre-2002) screwcaps.

While I'm on the issue of cork vs screwcap, you are likely to see a major advertising attack by the cork companies picturing their product as environmentally friendly etc. They don't tell you that only 15% of all cork production is used for wine, and that the environmental cost of ruining 6% of all wine with corks in has to be higher than replacing their 50c corks with a 15c screwcap. (Australian dollar costs here).

Cheers,

Andrew, do I understand you correctly that in AUS Dollars a single cork is $.50 and a stelvin in $.15 so its thirty five cents less per bottle of wine sealed under Stelvin?

Probably right, but then there is the cost of changing your production line which seems to be prohibitive to at least the small Mosel vintners I know. Anders

Well, for a 20-50$ bottle the cork is a minor part, but if you get a faulty bottle return rate of 10% then it's becoming an expensive part... For some reason, I don't find that proportion of faulty bottles in Mosel - more like 1% or even less... Anders

Tom; You winemaker ! - Me bean counter!

Lets put it this way - assuming that your price of $US50,000 is correct (and I have no reason to doubt that figure!) - let's assume that an average value of a bottle is a paltry $US20 per bottle.

Then that capital cost is recovered by eliminating the losses associated with only 2,500 bottles.

Over (say) 10 years, that is rather a cheap price to pay.

And that is ignoring the fact that a Stelvin capsule is half the price of a top grade cork (again, this is an educated guesstimate!).

Sure, a lot of money to outlay; but frankly - a no-brainer!!!

Perhaps you don't keep bottles as long as needed to find the 5% rate? (I don't know if that rate is justified or not, but just noting a possible explanation if it is)

Hello st.helier,

You're assuming the wine maker directly absorbs the cost of cork failures. IMHO, the end consumer absorbs the vast majority of such costs. If one were to estimate, for example, that only 1% of tainted bottles are actually returned for a refund, and that 10% of all bottles are tainted, then the cost of the equipment would be amortized over 2.5 million bottles.

TCA contamination is a question of minutes, not of years.

No, 250,000 bottles.
