2 Regions, 3 Glasses, 1 Wine Geek

May 28, 2022 Leave a comment

The assignment was simple. Compare 6 Cabernet Sauvignon wines from 2 famous winemaking regions in Chile. Find differences. decide on a favorite.

As with any assignment, let’s start with the theory.

Cabernet Sauvignon is unquestionably a king of Chilean wines – it is the best-known Chilean wine worldwide and it is the most widely planted red grape variety in Chile. It accounts for about 20%+ of all vineyard plantings in Chile, covering an area of about 99,000 acres, stretching through the entire country from north to south. At the same time, 97% of the Cabernet Sauvignon plantings are located in the Central Valley, spread between O’Higgins, Maule, and Metropolitan Region.

Narrowing it down to the wine-producing DOs, we are looking at the Maipo Valley and Colchagua Valley, two of the best-known Cabernet Sauvignon areas in Chile. These are also the two regions that are the subject of our assignment.

Maipo Valley is one of the oldest winemaking regions in Chile, with its terroir shaped by the Maipo River, which begins at the Maipo volcano, creating a patchwork of valleys at the elevation of 2,500 feet above sea level. Some of the areas in Maipo Valley see a minimal number of sunny days required for the red grapes to fully ripen, with a climate somewhat similar to Bordeaux.

Colchagua Valley lies about 80 miles south of the city of Santiago. Parts of the valley are crisscrossed by the Tinguinirica River, taking its roots from the volcano crater in the Andes, and descending from about 2,000 feet to the 360 feet of elevation above sea level. Colchagua Valley generally offers much warmer daily temperatures compared to the Maipo Valley.

Here are some of the views of the beautiful regions:



I’m purposefully avoiding descending into the discussion about the different soil types throughout both regions but of course, alluvial soils, colluvial soils, gravel, clay are all intermixed around both regions. I don’t believe I can intelligently speak to the effect of a given soil type as it comes to the resulting taste profile of the wine, but our main difference between the wines from the two regions should be driven by the warmer versus cooler climate and some differences in the elevation.

I hope this is enough of the theory and it is time to get to practice – the lab portion of our assignment.

This is where the inner geek came out guns blazing – and this is where everything all of a sudden became muddy and complicated.

I decided that the challenge of comparing the 6 wines is insufficient, and to make things more fun, I decided to was possessed to try each wine from three different glasses: Glass 1- Riedel Universal tasting glass (this is the one typically offered at all of the wine tastings), Glass 2 – Chef & Sommelier Open’Up glass, one of most aesthetically pleasing glasses for the daily drinking, and Glass 3 – Riedel Radical Cabernet glass (my favorite glass for the Bordeaux varieties).

The wines I tasted all come from well-known producers. I was familiar with some prior to this tasting (Los Vascos, TerraNoble, Maquis) and I had a lot of Los Vascos and TerraNoble Cabernet wines in the past. Regardless, this was quite a respectful selection of the wines, expectedly illustrative to represent the two regions. Three of the wines were 100% Cabernet Sauvignon, and 3 had Cabernet Sauvignon as a dominant component.

To explain in more detail what I did: on the first day, I poured each one of the 6 wines into the 3 glasses – non-blind, one by one. I then tasted each wine from those 3 glasses – you will see the notes below, describing my perception of the same wine in each of the 3 glasses. The glasses had their effect, even though Radical Cab and Open’Up glasses offered mostly similar experiences. Open’Up glass required the bottom section to be sufficiently filled or the nose of the wine was becoming lost. All of the second and third day tastings were done only using the Universal tasting glass. Below you can see all of the tasting notes, from which it is very easy to conclude that I was unable to come to any meaningful conclusions and find any meaningful, region-conforming differences between the wines.

Here we go:

Team Maipo Valley:

2017 Lázuli Cabernet Sauvignon Valle del Maipo (14.5 ABV, $45, 100% Cabernet Sauvignon)
Garnet

Glass 1: dark fruit, concentrated, iodine, forest underbrush, pyrazine
Interesting. Quite restrained. Not a lot going on.

Glass 2: much less expressive, just a hint of pyrazine
It is showing better. No idea how. Crunchy berry, soft tannins, still not very expressive

Glass 3: dark fruit, more focused than glass 1, a hint of bell pepper
Similar to glass 2. Dark fruit, baking spices, lots of minerality. Not very much Caberneish if you ask me.

Day 2: not good

Day 3: Fruit showed up. Fresh berries and eucalyptus. Is this a Cab? Not sure. Is it drinkable? Sure, on the third day.

2018 Miguel Torres Cordillera Cabernet Sauvignon Reserva Especial de Les Andes Valle de Maipo (14% ABV, $20, 100% Cabernet Sauvignon)
Concentrated ruby with bright hues

Glass 1: very similar presentation to the first wine. Dark fruit, a hint of bell pepper, very distant hint, a touch of eucalyptus.
Definitely a Cabernet profile, more explicit than the previous wine. Eucalyptus, cassis, bell pepper practically non-existent.

Glass 2: this glass requires much higher pour to get to the aromatics.
The wine appears more refined and elegant on the nose than glass 1, more focused on eucalyptus and cassis.
Delicious, earthy cab. Good acidity, cassis, earthy and restrained.

Glass 3: interesting. Almost gets to the barnyard space. Definitely more earthy than glass 2.
The best experience. Dark fruit, cassis, pencil shavings, crisp tart finish.

Day 2: good

Day 3: excellent. Dark fruit, eucalyptus. Round tannins, good structure, dark and supple.

2016 Echeverría Cabernet Sauvignon Limited Edition Maipo Valley (14% ABV, $25, 85% Cabernet Sauvignon, 10% Syrah, 5% Carménère)
Dark Garnet

Glass 1: very concentrated. Dark fruit, sapidity, earthiness, a hint of eucalyptus. Interestingly enough, all 3 wines so far are really similar.
The nice initial appearance of the fruit is instantly replaced by tannins. Serious French Oak tannins, front of the mouth is locked.

Glass 2: a much more elegant appearance than Glass 1. A hint of eucalyptus and bell pepper.
Fruitier than the previous 2 wines, nice load of dark berries, and then it is all tannins. Again, the wine appears to be more elegant.

Glass 3: similarly elegant to glass 2. Eucalyptus, bell pepper, and a touch of black pepper.
Berries, eucalyptus, and tannins. Should be outstanding with the steak.

Day 2: Excellent

Day 3: very good, open fruit – but not very much of the cab? I liked it more on the day 2

Overall notes: all 3 wines are very similar on the nose, showing differently on the palate. Earthy, concentrated wines. All need time to open.

Now, team Colchagua Valley:

2018 Maquis Cabernet Sauvignon Gran Reserva Colchagua Valley (14% ABV, $20, 90% Cabernet Sauvignon, 6% Cabernet Franc, 3% Carmenere, 1% Petit Verdot)
Garnet

Glass 1: bright and clean aromatics, cassis, eucalyptus, a hint of bell pepper
Plums, a touch of cherries, not a textbook Cabernet Sauvignon

Glass 2: interesting. Volcanic undertones, gunflint, almost a hint of sulfur, fresh crisp berries
Better showing, brighter fruit, some bitter undertones appeared (whole cluster?)

Glass 3: somewhat similar to the glass 2, but a bit more restrained
Amazing how much glass matters. This is almost at the expected level of Cabernet Sauvignon – a hint of cassis, mint. Still very restrained.

I’m so confused that I had to wash the glass.

Re-taste: it is not bad, but didn’t make a difference. Still, dry restrained, with some bitter notes on the finish.

Day 2: tight and closed

Day 3: definitely better. Bitter notes are gone. But the whole presentation is plum/cherry, not so much of the Cab Sauvignon

2018 Los Vascos Cromas Cabernet Sauvignon Gran Reserva Colchagua Valley (14.5% ABV, $22, 85% Cabernet Sauvignon, 10% Syrah, 5% Carmenere)
Concentrated ruby

Glass 1: dark berries, a hint of cassis, vanilla, bell pepper might be a product of my imagination
Delicious. Fresh, open, clean, dark berries, cassis, bell pepper, eucalyptus. A pretty classic cab if you ask me. Best of tasting so far.

Glass 2: Cassis and mint, medium intensity
Delicious. Very similar to glass 1, somehow with a bit more intensity of the flavors.

Glass 3: very restrained, cassis, bell pepper, a touch of tobacco
Delicious. Exactly as two previous glasses. Happy to drink every day.

Day 2: not good. Tight, closed.

Day 3: lots of tobacco and smoke on the nose. Dark fruit, borderline bitter. I don’t get this wine

2018 TerraNoble Cabernet Sauvignon Gran Reserva Valle de Colchagua (14% ABV, $20, 100% Cabernet Sauvignon)
Garnet color

Glass 1: dark berries, eucalyptus
Delicious. Open, bright, good acidity, ripe fruit, not necessarily a textbook cab, but fresh and delicious.

Glass 2: dark berries, sapidity, earthy, a hint of bell pepper
Fresh, delicious, crisp berries, a touch of cherries, a bit of dark chocolate.

Glass 3: a hint of bell pepper, dark fruit, earthy
Bright, open, good structure of tannins. A cab? Maybe…

Day 2: good

Day 3: beautiful, supple, good tannins, good structure, open fruit, good finish.

On the day 2, my preferences were with these three wines:

And then there were two. On the third day, I had two wines as my favorites – and they represented two regions.

For the final decision – Torres versus TerraNoble.

Wine geek at work

Nose: advantage Torres – dark chocolate, a hint of bell pepper. TerraNoble mostly closed

Palate: slight advantage Torres – better structure and better precision. Dark and concentrated. Will continue improving.

The winner: 2018 Miguel Torres Cordillera Cabernet Sauvignon Reserva Especial de Les Andes Valle de Maipo

So we can conclude that Maipo Valley won this strange competition, at least with a margin of error.

The assignment is complete. So what did we learn?

  1. Don’t play with your glasses, unless this is actually a goal of your exercise. Wine glasses matter and wine glasses can will confuse you.
  2. Hey, wine glass matters.
  3. I probably should’ve done the blind tasting instead
  4. Chilean Cabs need time. Practically all showed better on the second day.
  5. I was unable to find the real differences between Colchagua and Maipo wines

Oh well. Play with your wine. Have fun. One way or the other, experience is still an experience, and as long as you desire, there is always something to learn.

Do you have a favorite Chilean Cabernet Sauvignon? Care to share? Cheers!
