Screw Top Versus Cork – The Jury Is Still Out
Inadvertently, I run an experiment of cork versus screw top, and the results were interesting enough to discuss them here.
About a week ago, I pulled out of the cellar (which is actually a wine fridge) the bottle of 2004 d’Arenberg The Footbolt Shiraz MacLaren Vale from Australia (14.5% ABV). As I confessed in my blogging addiction in the recent post, before the bottle is open, in addition to just regular anticipation of wine experience itself, now I have added anticipation of the possible blog post which can be written based on the wine experience.
Or not. There are many possible was for the experience not becoming a blog post. Too many things to write about, too little time. Or you just hit the “writer’s block”. Or the experience is not worthy of being captured. Which was the case with this Shiraz.
d’Arenberg is a well known Australian winery, which just celebrated 100 years last year, producing substantial range of typical Australian wines, such as Shiraz, Grenache, Chardonnay, Cabernet Sauvignon and more. I had pleasure of meeting Chester Osborn, d’Arenberg’s winemaker in third generation, and even have couple of bottles with his signature in my cellar (by the way, what do you do with those signed bottles? I should make a separate post to discuss this interesting question).
Now, I didn’t know what to expect from this bottle of Shiraz. The Footbolt is one of the introductory level Shiraz wines from d’Arenberg, but that doesn’t mean anything. Cork is out (regular cork, just keep reading to see why it is important), and judging by the color alone, this wine didn’t reach its prime yet – dark ruby in color. But the nose and then the palate were inconclusive. Acidity would jump up and down with every sip, and while the wine had enough fruit, it was simply not getting together, definitely lacking the balance which is all so important for me in the wine. So, based on this wine alone, the blog post was not born.
And then yesterday I pulled out another bottle of d’Arenberg wine from the same vintage:
2004 d’Arry’s Original Shiraz Grenache McLaren Vale (14.5% ABV) – a blend of 50% Shiraz and 50% Grenache . With the screw top. That was an “aha” moment. Same vintage as the previous wine – but wit the screw top – how different the experience will it be?
No “pop” of the pulled cork. Just a quiet “tsk-tsk-tsk” of unscrewing the top. In the glass, this wine looked like it was made yesterday – dark ruby, very concentrated color. From the get go, the wine showed beautiful fruit on the nose, ripe plums, equally supported on the palate with fresh fruit and energetic acidity.
About 45 minutes or so later, when I poured another glass, the wine tasted almost sweet – the thought was “what happened”? This was a totally a different wine compare to the way the wine started. Another half an hour or so – and we were presented with the new wine again – dark concentrated fruit, firm structure, tannins and acidity all summing up into a gorgeous balanced wine.
Wine ageing in the bottle is typically associated with the tiny inflow of oxygen through the cork. In case of screwtop, the oxygen doesn’t get to the wine at all. Thus my theory is that once you open a bottle under the screwtop, the very quick ageing process starts off, which takes the wine through the different “taste stages” in the rapid succession. Then at the same time, the wine is changing its taste in the glass no matter what, so may be that rapid taste changing has nothing to do with the way the bottle was closed.
Ideally, of course, I would love to compare two identical bottles (same wine, same vintage), only one closed with the screwtop and another one with the regular cork (I believe I actually read about some producers who are doing that). In this experiment, the Shiraz Grenache under the screwtop was a clear winner, but it is hard to tell what it has to do with the screwtop versus regular cork versus the two wines being just differently made.
I guess I can end this report with the words “to be continued…” – and I would love to hear your thoughts. Cheers!
Wednesday’s Meritage – Wine Quiz Answer, Ageing of California Cabs, Is 0.05 an answer?, and more
Meritage time!
As usual, we are starting with the answer to the wine quiz #58, Grape Trivia – Syrah. In the quiz, you were supposed to answer 5 questions about Syrah, a.k.a. Shiraz.
Q1: Where is Shiraz?
A1: Shiraz is a town in Iran (previously Persia) where supposedly Syrah was originated.
Q2: Which white grape often plays a role of blending companion for Shiraz?
A2: Viognier is often added to both Syrah (Côte-Rôtie) and Shiraz. In many cases you can see Shiraz Viognier written on the labels of Australian wines.
Q3: One of the appellations below can be removed from the list – can you tell which one and why? For the answer to count, “why” explanation is required
A. Cornas, B. Côte-Rôtie, C. Crozes-Hermitage, D. Hermitage, E. Saint-Joseph
A3: Cornas. While Syrah is the only red grape allowed to be used in all of the appellations above, all appellations except Cornas also allow addition of white grapes (Viognier or Marsanne and Roussanne) to the final wine.
Q4: About 100 years ago, Syrah was a popular addition to the wines of one well known region – now this practice is totally illegal by the appellation rules. Do you know what region was that?
A4: Bordeaux. Syrah was a popular addition to Bordeaux wine, providing the structure and flesh. Of course the practice is illegal according to Bordeaux AOC rules, but it is still quite popular in the other regions, such as Australia, where you can often find Cabernet Sauvignon Shiraz wines.
Q5: Where do you think are the oldest in the world continuously producing Syrah vineyards are located? Can you guess the approximate age of the vines?
A5: Australia. It is very difficult to figure out who was first and who was not, as in the wine world, there are always multiple claims to the “first” and “oldest” bragging rights. Based on the information I came across in this forum discussion, the oldest Shiraz vines had being planted in 1846 in the Jacobs Creek area, and Schild Estate is producing the wine called Moorooroo Shiraz from those old vines.
And the winners are… The Drunken Cyclist (I think for 5 times in the row!). He got all 5 questions correctly – great job, Jeff! Very close right behind him (with 4.5 out of 5 points – very close in the area for Shiraz, but named a different country – is Barbie from Blindly Guessing Grapes. If you are not familiar with her blog – check it out, she is constantly challenging herself to taste and learn about different grapes, definitely worth your attention. Honorable mention goes to Red Wine Diva, who correctly answered 3 out of 5 questions. Great job all, enjoy your bragging rights!
And now, to the interesting stuff around the vines and the web!
First I want to mention an interesting post by Steve Heimoff, where he is talking about change in perception of what ageable California Cabernet Sauvignon is, from 1970s to today. Steve’s point is that back in the 70s, to be considered age-worthy, Cabernet was supposed to taste bad on the release – where this is definitely not the point now. Read it for yourself, and as usual, don’t forget to read through the comments section, as it contains a lot of interesting information.
Next subject is currently widely discussed in many alcohol-related blogs – NTSB (National Transportation Safety Board) recently came up with recommendation to lower allowed alcohol blood limit to 0.05 (down from 0.08 which is currently the limit). Both Steve Heimoff and W. Blake Gray wrote blog posts about it, which you can read here and here, advocating the idea that just lowering of the alcohol blood level will not be the solution for DUI-related accidents. They both covered the subject quite well, so I’m not going to repeat all of their arguments – but I recommend that you will read their posts, as in the end of the day, this relates to all of us and our ability to have a glass of wine with the meal in the restaurant.
There is also something else I want you to think about here. My friend Emil sent me a very interesting link tot he blog post titled “Survivorship Bias“. The post is very (very!) long and has nothing to do with wine – it is however a very (very!) worthwhile reading. This post is talking about the fact that when we analyze the problem, we tend to focus on successful outcome only, and we forget to carefully look on all the failed results and dead-end paths (it is impossible to give you a good summary in one sentence, you will be better off reading the post). The connection here? I believe that most of drunk-driving accidents were caused by the people whose blood alcohol level was far exceeding 0.08, forget 0.05. Majority of the people involved into DUI accidents never thought of what the allowed blood alcohol level is – 0.08, 0.05 or whatever, so lowering the limit will only allow to collect more fines and get in the way of more people’s lives – but it is not going to address the problem itself and reduce the number of drunk-driving related accidents. By no means I advocate or promote drunk-driving, this is definitely a serious problem which needs to be solved – but in order to solve this problem, it should be analyzed properly first, and this is what I believe this 0.05 recommendation is lacking.
And this is all I have for you for today. I think you are looking at lots of interesting reading, and if you want to discuss any of this “news”, this is what the comments section is for.
The glass is empty – but refill is on the way. Until the next time – cheers!
Weekly Wine Quiz #58: Grape Trivia – Syrah
Welcome to the weekend! To start your weekend right, it is the time for our traditional grape and vine exercise.
We are continuing the grape trivia, and today’s subject is … Syrah, or as they call it in Australia, Shiraz.
Syrah is a red grape with thick black skin, capable of producing full-bodied, big and powerful wines. Primary aromas associated with Syrah are usually of blackberry and black pepper, but as the wine ages, it shows a number of very diverse flavors, such as leather, tobacco, chocolate and more. Syrah is known under the name of Shiraz in Australia and South Africa. France, United States (California, Washington, Oregon) and Australia are typically considered to be the source of the best in the world Syrah wines, but Spain, Italy, Chile and Argentina are all producing very interesting Syrah wines as well.
Now, let’s move on to the quiz. As before, the quiz consists of 5 questions, and the answers will be provided next Wednesday.
Q1: Where is Shiraz?
Q2: Which white grape often plays a role of blending companion for Shiraz?
Q3: One of the appellations below can be removed from the list – can you tell which one and why? For the answer to count, “why” explanation is required
A. Cornas
B. Côte-Rôtie
C. Crozes-Hermitage
D. Hermitage
E. Saint-Joseph
Q4: About 100 years ago, Syrah was a popular addition to the wines of one well known region – now this practice is totally illegal by the appellation rules. Do you know what region was that?
Q5: Where do you think are the oldest in the world continuously producing Syrah vineyards are located? Can you guess the approximate age of the vines?
Enjoy your weekend, good luck and cheers!
