This was an unimaginable tasting, hosted by Stephen Browett of Farr Vintners, evaluating the an identical wines sealed beneath cork and screwcap, over a variety of varieties and vintages. This tasting was unusual, and possibly distinctive in its scope. Whereas many wineries have completed inside trials of cork versus screwcap, it’s uncommon for them to proceed with these trials after which do the comparability some years later.

What was the motivation for this comparability? ‘From 1996 onwards white Burgundy had horrible points with oxidation,’ says Stephen. He moreover referenced the reality that in his annual Southwold tastings of prime Bordeaux 10 years after launch, he’d get cork taint throughout the fluctuate of 5-10%. And he’s moreover labored intently with Kumeu River over time, and they also switched to screwcap as shortly as they might as a consequence of cork factors. ‘Michael Brajkovich opened a complete pallet of 1999s and 40% had been corked,’ says Stephen. One different particular person he’s labored with intently who has shifted to screwcap is Jean-Marie Guffens (Guffens-Heynen and Verget). ‘He’s an mandatory white Burgundy producer, nonetheless he’s not from Burgundy and he has an open ideas,’ says Stephen. ‘In 2003 he started doing screwcaps with Farr Vintners, so because of this we had been ready to do this tasting.’ David Gleave of Liberty Wines, an enormous champion of screwcap, moreover helped by arranging some Italian wines.

To start with, some caveats. Corks are all completely totally different, so when tasting a cork-sealed bottle with a bit little bit of age on it, we might anticipate finding a variety of wines with completely totally different ranges of enchancment, because of the pure variability of the cork. So this is not meant to be a actual experiment.
Second, the screwcap is not the closure. The closure is the wadding beneath the lid, and this determines the screwcaps oxygen transmission price (OTR). If the wadding is shiny and metallic, then it is the tin/saran liner. Just about all extreme screwcapped wines have this liner, and it permits very low OTR. Initially, Verget used the Saranex liner (which seems like white plastic), which they caught with until 2014. This allows a bit further oxygen transmission than the saran/tin liner. Verget did screwcap from 2003, and from 2004 they moved to 50% screwcap. In 2012 they ditched cork and moved to Diam, so a lot of these comparisons are between screwcap and Diam, and that’s indicated the place it’s the case.
Third, it not merely OTR that causes cork/screwcap variations. Corks are normally not neutral and may launch small portions of phenolics into the wine, and this interaction between the cork and the wine is probably important. Moreover, corks have oxygen dissolved in them, and they are going to launch a number of of this over the first few months after bottling, sooner than a mild state OTR is reached. And for an excellent cork, there is not a ‘respiration’: the OTR price must be pretty low.

Wines had been tasted in pairs, and we weren’t suggested which was which throughout the pair, although colour normally gave a strong clue with the older wines. These are my notes. We took a bunch score and these outcomes are included beneath my notes. It was clear that the outcomes weren’t clear decrease, and there was loads of variation among the many many tasters (listed beneath: an expert bunch, from completely totally different backgrounds). Primarily probably the most clear decrease outcomes had been with the Kumeu River Chardonnays (screwcap hottest by just about all), the Felton Freeway Pinot (screwcap hottest clearly). For lots of, the room was reduce up, which was a shock (I was anticipating there to be quite extra unanimity, and likewise an enormous vote in favour of screwcap), and in pretty a few cases the cork/Diam-sealed wine was hottest. Be mindful, though, that for many of the older Verget wines the screwcap had the Saranex liner, and so there may have been a further pronounced completely totally different with the saran/tin liner.
If you would like a conclusion, then the right I can present is that this: it is tough.
