The Impact of Ripening Stage and Maceration Time on Cabernet Franc

I am on a quest to understand how to tell the hallmarks of a good Cabernet franc wine. This article, "Sensory representation of typicality of Cabernet franc wines related to phenolic composition: Impact of ripening stage and maceration time," was in my email box and it seemed the answer to the question of what a good Cabernet franc tastes like.
The previous blogpost, What is JAR? was written to familiarize myself with the definition of "typicality" in wine and how to measure typicality using the Descriptive Analysis (DA) and Just About Right (JAR) Analysis. The authors focused their research on the influence of the harvest date and the maceration time on the wine style.
What are the hallmarks of wine quality?
There were 12 identical wines used in the DA and JAR analyses made from Cabernet franc grapes grown in the Loire Valley. For the DA analysis, a panel of 17 judges not related to the wine industry was chosen. Wine samples were poured at room temperature and resulted in the generation of 15 attributes from the judges. The judges scores each of the 15 attributes on a scale with “low intensity” on the left and “high intensity” on the right.
For the JAR analysis, nineteen judges (5 winemakers, 7 oenologists, 4 wine-merchants-maturers and 3 technicians) took part in the experiment. Twelve attributes were selected for evaluation. The judges were instructed as follows: “for each descriptor”, answer the following question: “do you think this descriptor is ideal from a typicality point of view, too strong, or too weak?” The 19 judges also were instructed as follows: “For each wine presented, answer the following question: “do you think this wine is a good example or a bad example of what an Anjou-Villages wine is?”
The takeaway from this analysis was that ripening stage was more important than maceration time in determining the typicality of a Cabernet franc wine from the Anjou-Villages in the Loire Valley.
  • Prediction of wine quality based on the berry composition should also include their extractability during winemaking
  • Ripening stage had a major influence on tannin extraction: tannin extraction from skins increased with ripening and then decreased
  • As expected, acidity was lower and anthocyanin and alcohol contents higher with more advanced ripening
  • Phenolic composition at harvest also explained the wine style
  • Wines from later harvests were richer in proanthocyanidins, which may be related to their higher typicality scores
  • From a sensorial point of view, harvest date was significant for typicality assessment: wines with the latest harvest date were more typical. Maceration time was not significant
To be honest, I wasn't surprised at their results. When we harvest our Cabernet franc, we are always looking at the balance of brix (sugar content), pH and titratable acids. If the harvest can be prolonged and sugar accumulation continued, then our Cabernet franc has the typicity of a good Cabernet franc that we are aiming for. Is there a typicality for Cabernet franc wine made and grown from grapes in our corner of Connecticut, that is the question.

What is JAR?

We were in the midst of a heat wave last week that lasted from Thursday, July 2 to Saturday July 4. This week on Monday and today, we were getting pummeled by rain. These two events conspired to keep us out of the vineyard so it is a good time to read up on literature that I've downloaded and keep meaning to read.
The article that I am currently reading is called, "Sensory representation of typicality of Cabernet franc wines related to phenolic composition: Impact of ripening stage and maceration time," it is quite a dense article published in Analytica Chimica Acta.
One acronym caught my eye, called JAR, which means Just About Right (JAR) and refers to how to assess the typicality related to a Protected Designation of Origin (PDO).
Typicality is defined as the characteristics of a wine from a terroir including environmental factors, variety, cultivation and winemaking practices. The resulting biochemical and sensory characteristics of the wine make it possible to differentiate, identify and recognize the wine as coming from a specific PDO.
A little further into the article, I came across a tabulation of the descriptive attributes used to evaluate sensory properties of wines in the quantitative descriptive analysis (DA) and the Just About Right analysis (JAR)
Descriptive Analysis (DA) Attributes Description
Visual Olfactive Color Intensity Intensity of colour, from pale to dark
Black currant Blackcurrant (fruit and liqueur)
Stewed red fruits Jam of strawberries or raspberries
Other red fruits Fresh red fruits: strawberry, raspberry
Pastry Vanilla, cinnamon, candy
Alcohol Alcohol
Empyreumatic Smoky, toast
Spciy Pepper
Vegetal Green wood, freshly mown grass
Humus Undergrowth, moist wood, ground
Animal Leather, stable
Mouthfeel Acidity Intensity of sour taste
Bitterness Intensity of bitter taste
Alcohol Intensity of alcohol taste
Astringency Intensity of astringent taste
Just About Right Analysis (JAR)
Visual Olfactive Color Intensity Intensity of colour
Shade Shade of colour, from orange to purple
Olfactive Odor intensity Intensity of odor
Red fruits Shade of colour, from orange to purple
Black fruits Wine aromas that suggest black currants
Ripe fruits Wine aromas that suggest ripe fruits, candied fruits
Vegetal Vegetal, herbaceous, sweet pepper
Mouthfeel Soft tannins Tannins with smooth and fine textured astringency
Acidity Perceived acidity
Thickness The viscosity as an indicator of a full-bodied style
Astringency Drying and roughing sensation
Length The time that aftertaste persists in the mouth
The authors used these descriptors from Descriptive Analysis (DA) and Just About Right Analysis (JAR) and a panel of judges to enable them to draw conclusions. More about this aricle coming in another blog.

Vintage 2026: July 1

The time is flying by as it usually does when there is vineyard work to do. On June 23, there was a huge rain storm that gave us 2 inches of rain. Rain in the forecast during flowering is a thing to worry about because it can lead to poor fruitset. I took pictures of our varieties on June 22 and most of our varieties were in bloom, if not the beginning of fruitset. The Cabernet Sauvignon was in prolific bloom so I wondered what the 2 inches of rain would do to the fruitset there.
Here are some pictures I took before the rain and after the rain:
Variety Before Rain After Rain
Auxerrois
Chenin Blanc
Chardonnay
Cabernet Sauvignon
Cabefrnet Franc
Barbera
Thankfully, the rain didn't affect the fruitset and the Cabernet Sauvignon looks very good. The next thing we have to worry about is the heat wave coming for the next four days!

Koimari Tropical Saga Sake and Tempura

Not too long ago, my husband made tempura and we paired it with Koimari Tropical Saga Sake. My husband is always on the look out for interesting sake to drink with foods. In February, we had a sake made by Noguchi Naohiko who is known as the God of Sake in Japan.
I was looking forward to drinkng this sake made in Saga Prefecture since I trust my husband's procuring prowess. I found that this Koimari Tropical sake was fragrant and quite fruity on the finish and while I enjoyed the sake very much, I wasn't sure if it was the perfect pairing with the tempura. I think my palate was hoping for something a tad drier, but here I am being a little over critical. The tempura was delicious!
The Saga Sake is made in Koimari Brewery founded in 1909 in Imari City, Saga. The sake is a Junmai Daiginjo. Junmai means that the sake was made with only rice, koji and water. Daiginjo refers to the fact that it ranks as the highest grade of sake. This style of sake is made with rice where 50% or more of the outer layer of rice kernel is polished away and fermented at low temperature. This sake has a pleasant fruity aroma and still retains its fragrant aroma in your mouth.
On their website, they suggest pairing the Koimari "Tropical" Sage Sake with herb roast beef, Wagyu soft jerky, pork and foie gras pâté de campagne, fried horse mackerel with plum shiso, bluefin tuna, crab with shiraae sauce, apple salad with yogurt and sake lees sauce. They also suggested a sake they make called Mitsutake "Crisp" Junmai Daiginjo, which sounds like a better pairing for tempura. I may suggest that my husband get this sake for us to try.
