Your Sparkling questions answered

While Rob waits patiently for our Pinot Noir to ripen just enough to pick for our Sparkling, let’s take a closer look at some of your questions about one of our most popular and “Trophy-winning” (have I mentioned that before?!) wines.

What’s all the kerfuffle about using the word “Champagne”?

Although sparkling wines are produced around the world, legally the word Champagne is reserved exclusively for sparkling wines from the Champagne region in France and made in accordance with regulations governed by the Comité Interprofessionnel du vin de Champagne (CIVC) and protected under a treaty (so, I guess they’re pretty serious about it!).

For champagne to be champagne, the grapes need to be sourced from specific parcels in the Champagne appellation (which is short for a long fancy French term which means “protected designation of origin”) using specific vineyard practices, pressed using regimes unique to the region and made using secondary fermentation of the wine in bottle to create the bubbles (read on for more information on how this is done).

What is involved in making Sparkling using the traditional method?

The traditional method of making Sparkling wine involves a number of steps…

  1. The grapes are pressed and go through a primary fermentation like any other table wine. It is then bottled.
  2. A second fermentation is induced by adding more yeast and sugar (usually in the form of grape juice). A crown seal (like a beer bottle) is added to the bottle and the fermentation occurs in the bottles, which creates the bubbles.
  3. The wine is then left to sit on yeast lees. In Champagne, the minimum amount of time specified by the appellation is 1.5 years. This is also the minimum amount for Rob, but he usually leaves it to mature for much longer than this.
  4. After aging, a process called remuage (or “riddling” in English) is performed either manually or mechanically, to gradually invert the bottle and settle the lees into the neck.
  5. The neck of the bottle is frozen, whereupon the lees freeze to a sold block, and the crown seal is removed. The pressure in the bottle forces the frozen lees out of the bottle. The wine is then topped up with additional wine (le dosage) and quickly corked (or another crown seal added) to maintain the bubbles. The dosage is not only designed to replace the volume lost during the disgorging process, but gives the winemaker a change to adjust the sweetness of the wine. For Rob, the dosage he uses is much drier that most.

Is there any other way to make Sparkling wine?

A large proportion of Australian Sparkling wine is not made using this time consuming and expensive method. There are others ways to make Sparkling wine, including adding a gas under pressure to the wine to add the bubbles… just like how your soda stream works at home. But we don’t recommend using your soda stream to add bubbles to your wine!

 

Why does Rob use a crown seal instead of a cork?

Well, firstly, he’s terrified someone will take an eye our with a cork! Secondly, with a crown seal there is very little chance that any gas can escape the bottle, meaning you can hang onto a bottle of Somerled Sparkling for years and it will be just as bubbly as it is today. Given the porous nature of cork, it is inevitable that some of those bubbles will disappear over time.

How do you make a Sparkling white wine out of a red grape variety?

If you bite into a red grape, what colour is the flesh usually? Most red grapes have white flesh. In fact, there are very few varieties of red grapes in the world which have red flesh (Alicante is one of them). Actually, the only thing the contributes to the colour of a red wine is its skin.

So, if you press the grapes ever so carefully and remove immediately separate the juice form the skins then you can make a white wine!

Traditionally, Sparkling wine is made from Pinot Noir, Pinot Meunier and Chardonnay.

 

Do you have any other Sparkling related questions for us? We’d love to see your questions and thoughts in the comments section below.

 

How about this weather??

At least the rain is good for the garden… but what about the grapes?

To be perfectly honest, it’s not ideal. Refer back to last week’s post for our discussion on powdery mildew (did I jinx it?!). And tune in next week to find out what exactly what effect this weather will have. In the meantime, send good thoughts to the wine Gods!

And so it begins…

Vintage 2018 that is! Even though a few wineries in the region have seen the first fruit picked and into the press this week, we still have at least a couple of weeks to wait. Rob sources the grapes for his wines (except the Shiraz) from some of the highest vineyards in the Hills… it’s for this reason that it takes a little longer for vintage to be well and truly underway for Somerled.

Early veraison in pinot noir grapes at Paul Henschke's vineyardThat said, there is still plenty happening…

At Paul Henschke’s vineyard in Summertown, where Rob will get the Pinot Noir for our Sparkling and Rosé, we’re only just seeing the first signs of veraison in some of the younger vines (see photo). At this stage it won’t be picked until the second week of March.

Things are a little more advanced in Charleston at Kim Anderson’s vineyard. Veraison is close to 100% in the Sauvignon Blanc (this will be used for the Fumé as well), the Chardonnay is at around 50% and Pinot Noir (for our dry red) is somewhere between the two… in short, lots and lots of fully coloured berries, but low in sugar and high in acid. Still a little way to go, although Kim will do the sugar level test on samples of the fruit on Monday next week.

For a recap on what veraison is, visit our post here.

Even though we’ve had some hideously hot weather of late, the nights have been nice and cool (down to 5 degrees some nights!)… this is a bonus for grape flavour and wine quality as it minimises the overall stress on the vine.

Another positive for this vineyard is that it’s looking really healthy. How do we know? Well, there are a couple of telltale sign of a healthy vineyard…

Pest free – There is no sign of Light Brown Apple Moth or scale insects

Insect pests are luckily quite uncommon in Australian vineyards but the Light Brown Apple Moth (LBAM) caterpillar, a native, can feed on the young berries, leaving scars for bunch rot fungi to enter the fruit.

Scale insects are sap suckers which also produce a honey dew which is the favourite food of sooty moulds, damaging the fruit.

Beneficial insects – There are really high populations of beneficial insects such as the Trichogramma wasps, lacewings, ladybirds etc.

Beneficial insects are the species which prey on the pest species eg LBAM and scale, keeping the pest numbers below the damaging levels.

Disease free – The vineyard is free from powdery mildew.

Grapevine powdery mildew, caused by the fungus Erysiphe necator, is a common fungal disease which can render the vine leaves dysfunctional. It slows photosynthesis and it reduces yield and quality of grapes and the resulting wines.

The canes and leaves of the vine (collectively termed the ‘canopy’) also give us an indication of overall health. Ideally the shoots have stopped elongating by this stage. However the youngest leaves must remain green and active so that the energy is directed towards moving sugars and all the lovely flavour precursor compounds towards the fruit which form the basis for what we’ll be tasting in the finished product. The older leaves have done their work by now and it’s ok to see a few of these yellow; after all they did emerge back in September!

We need your help!

We are very close to launching a new initiative for our friends who don’t live in Adelaide or who are unable to visit us at the Cellar Bar when we run special events.

How would you like to be involved in tastings run by Rob and special guests from the comfort of your own home, surrounded by your friends and family (or on your own if you ‘re like me and don’t like sharing!) and some delicious wines?

Sounds too good to be true right? Wrong!

Our first “Virtual tasting” will be available to you very soon, but in the meantime, we’d like you to have a think about what topics you’d like to see pop up throughout the year. Would you like to see a comparative look at Shiraz across different regions? What about a vertical Chardonnay tasting?

We’d love to hear your suggestions… so please leave us a comment below.

And for any suggestion which becomes a tasting, we’ll dedicate it to you! That’s right… It will be forever known as the “John Smith Somerled Shiraz vs Penfolds Grange comparative tasting”! PS. This particular tasting may cost you a little extra…

What next for the 2015 Shiraz?

The 2015 Shiraz is currently being prepped for bottling and will be ready for your glass….. mid-2019. Ok, ok, I know it’s a way off yet, but this little beauty needs a lot of love and care before it’s ready to drink. Let’s a have a closer look at what is happening behind the scenes.

Rob Moody, Somerled winemaker, pictured in the barrel hallSo, a couple of weeks ago you would have read that the 2015 Shiraz has been in barrel for well over two and a half years. It has now been racked out of those barrels for the last time and is sitting in tank waiting for the next steps in the process.

Step 1: Fining

Firstly, a specific quantity of fining agent will be added to the tank to bind all the unwanted compounds in the wine together in clumps so they sink to the bottom of the tank.

The purpose of adding a fining agent to wine is to soften or reduce its astringency and/or bitterness; remove proteins capable of haze formation; or reduce colour by the adsorption and precipitation of polymeric phenols and tannins (in white wines). The fining agent reacts with wine components either chemically or physically, to form a new complex that can separate from the wine (Australian Wine Research Institute)

Commonly-used fining agents include…

  • Gelatine
  • Isinglass (derived from fish!)
  • Egg albumen
  • Casein
  • Skim Milk
  • Bentonite
  • Carbon
  • Polyvinylpolypyrrolidone (PVPP)

Rob Moody in the lab with the Somerled 2015 ShirazThis is a photo of a very serious looking Rob in the winery last week trying to decide which fining agent to use on the Shiraz. The quantity and type of agent used can cause subtle changes in the structure and taste of a wine.  Although Rob adores the 15 Shiraz as is, he did wonder if it needed a little softening on the tannins. So, in the lab, he compared samples using 50 parts per million (ppm) of gelatin, 100 ppm gelatin and one using PVPP against the standard to come up with the right one for the job. The sample using 100 ppm gelatin was the winner – the tannins were softened nicely and the middle palate became a lot rounder and softer, without damaging any other characters of the wine.

Step 2: Cold stabilisation

Have you ever drunk a wine and found what looks like shards of glass in the bottom of the bottle or, even worse, your glass? Well, don’t freak out… it’s not glass, but completely harmless and natural tartrate crystals which can form when a wine hasn’t been properly temperature stabilised. They are scientifically known as potassium bitartrate, but if you’re a whizz in the kitchen you might also know them as cream of tartar!

Tartrates occur in wines when potassium and tartaric acid, both naturally occurring products of grapes, bind together to form a crystal. They are a normal bi-product of a wine as it ages, but cold temperatures (usually below around 4 degrees Celsius) can make them naturally combine with potassium to form a crystal.

The way to avoid this happening is to force this process in the winery before bottling. The tank is chilled down so far that ice forms on the outside and the tartrates form and sink to the bottom.

Step 3: Filtration

So, now that we have all these clumps (!) and crystals in the wine, what to do with them?

The final step in the process is to pass the wine through a filter on its way to the bottling line. This will remove all those unwanted particles and leave us with a beautifully clean wine, ready to be enjoyed by you…… in a year or so. But, hey! We have plenty of 2013 (and the 2014 still to come) to keep us going until then.

It should also be pointed out that the removal of these tiny fractions adds to the remarkable cellaring potential of Rob’s wines. Last weekend, I was lucky enough to sip on a 1998 Shiraz that Rob made and it definitely did NOT taste like a 20 year old wine! So, not only will we be enjoying Rob’s 2013 Shiraz at the cellar bar this weekend but also for years to come (if we can hang onto it for that long!).

Looking for something to do this weekend? If you’re in Adelaide and would like to see what the 2015 will taste like this time next year, we have a few bottles of 2014 that we’ll open for tasting at the Cellar Bar in Handorf. Mention this post for your chance to try it before anyone else does!

Stop the presses!

(did you see what I did there?!)

Last week, I explained what was happening with the Sparkling vintages in the pipeline. If you missed it, catch up here.

Since then, Rob has filled us in on some sneaky experimenting he has been doing behind our backs.

Back in 2012 he kept two barrels of 2012 Sparkling aside with the view to adding them to the 2013 – he had the idea that adding slightly aged wine to the sparkling would increase it’s body and complexity. In the end, he only used one of those barrels.

Anyway, the point is, it’s been racked off into bottles and shaken down (to get the lees into the neck ready for disgorging) and now Rob is testing out ideas for it. Watch this space…!

Where to start…?

On a day like today, what better place than with Rob’s go to thirst-quencher… Sauvignon Blanc.

We source the grapes for this classic Adelaide Hills variety from a vineyard in Charleston where the season is shaping up to be a good one. Some early hail damaged the vines a little, which warranted a strict disease management program. Unfortunately, the wet and very warm weather resulted in some downy mildew, but the damage was insignificant.

Downy mildew loves wet and warm conditions… for those of you interested, the rule of thumb for optimal disease conditions is a minimum of 10 mL rain with the temperature not falling below 10 degrees over a 24 hour period.

The grapes are currently at early veraison (see picture) and still have a lot of growing up to do in fact each berry will double in size between now and vintage.Sauvignon Blanc graoes

Veraison is defined as the stage at which three simultaneous but separate processes begin.

1. Each berry soften as the cells within the grapes begin to produce more juice and the skin becomes thinner.

2. Sugar starts to accumulate and acidity of the grape starts dropping away.

3. Colour starts to change – in Sauvignon Blanc this is a change from emerald green towards being translucent.

But, what about this week’s hideous heat, I hear you ask?

Our growers are well prepared for short burst of hot weather and have been carefully metering out irrigation to counteract the stress and high water use of the vibes at this time.

Also, the relatively “cool” nights of the Adelaide Hills allow the vines to recover without losing their precious leaves.

In other words… don’t panic, they’ll be fine!
