WINE TASTING TECHNIC

How to Taste Wine?
1. Look
Check out the color, opacity and viscosity (wine legs). You dont really need to spend more than 5 seconds on this step.
How to judge the look of a wine Color and opacity of wine can give you hints as to the approximate age, the potential grape varieties, the amount of acidity, alcohol, sugar and even the potential climate (warm vs. cool) where the wine was grown.
Age:
 As wines age they tend to change color towards more yellow and brown colors. Red wines also tend to become more translucent.
Potential Grape Varieties: Here are some common hints you can look for in the color and rim variation
a Nebbiolo-based wine will have a translucent brick color
a red blend with
 Merlot in it will have a slightly orange-tinged rim
a
 Malbec will often have a magenta pink rim
a youthful
 Syrah from a cool climate will have a blueish tinted rim
Alcohol and Sugar:
 Wine legs can tell us if the wine has high or low alcohol and/or high or low sugar.
2. Smell
Pick out at least 2 flavors and take your time identifying them. There are 3 types of wine aromas:
Primary Aromas come from grapes and include fruits, herb and flower notes
Secondary Aromas come from fermentation and yeast aromas.
Tertiary Bouquets come from aging, oxidation and oak such as baking spices, nutty aromas and vanilla.
Primary Aromas: Primary aromas are from the type of the grape and the climate where it grows. For instance, Barbera will often smell of licorice or anise, and this is because of Barbera grapes. Cabernet Sauvignon with blackcurrant or Capsicum aromas.Generally speaking, the fruit flavors in wine are primary aromas
Secondary Aromas: Secondary aromas come from the fermentation process (the yeast), Malolactic fermentation, on lees process, Secondary flavors are what you would expect come from the winemaking process—fermentation, malolactic conversion, and especially the influence of oakthink toast, vanilla, cedar, spice, mocha or coconut.
A great example of this is the sour smell that you can find in Brut Champagne that is sometimes described as bready or yeasty, biscuits These sour aromas are present in all wines at some level.
Tertiary Aromas: Tertiary aromas (classically referred to as bouquets) come from aging wine. Aging aromas come from oxidation, aging in oak and aging in bottle over a period of time. The most common example of this is the vanilla aroma associated with wine aged in oak. Other more subtle examples of tertiary aromas are nutty flavors found in vintage Champagne or dried fruit aromas that are associated with older red wines.
       3. Taste
Two elements make up taste: flavor and structure.
Flavors such as lemon, raspberry or coconut.
Structure such as the level of sweetness, body, alcohol, acidity, and tannin.
Profile The taste of wine is also time-based, there is a beginning, middle (mid-palate) and end (finish).
Sweetness:
The best way to sense sweetness is on the front of your tongue in the first moment you taste a wine. Wines range from 0 grams per liter residual sugar (g/l RS) to about 220 g/l RS. By the way, 220 will have a consistency close to syrup!
Dry Wines Wine is dry if it has less than 4g/l RS which is equivalent to a 1/2 teaspoon of sugar per glass.
Off- dry 5-9g/L
Medium dry ( 10-18g/L)
Medium Sweet (19-45g/L)
Sweet (Up 45g/L) Sauternes,Port
Very Sweet/Luscious
Acidity:
Acidity plays a major role in the overall profile of a wine because higher acidity wines tend to taste lighter in body. You can use these clues to determine if the wine is from a hot or cool climate and even to determine how old the wine is and how long it can age
Acidity refers to pH
 There are many types of acids in wine but the acid were discussing is simply the pH. Acidity is how tart a wine tastes. pH in wine ranges from 2.6 which is mouth-watering to about 4.9 which is flat.
Most wines
 range between 3 and 4 pH.
High Acidity
 wines are more tart and taste lighter.
High Acidity
 can indicate a wine from cooler climate region or wine grapes that were picked early.
Low acidity
 wines tend to taste smoother and have more body.
Super low acidity
 wines will taste flat or flabby.
Acidity Matters
 Wines with high acidity taste less sweet than wines with low acidity.
Tannin is a red wine characteristic  and it can tell us the type of grape, if the wine was aged in oak and how long the wine will age.
Tannin comes from 2 places: the skins and seeds of grapes or oak aging.
Oak Tannins
 Tannin from oak will often taste more smooth and round. It typically hits your palate in the center of your tongue.
Grape Tannins
 Tannin from grape skins and seeds is typically more abrasive and tastes more green.
Most red wines have some combination of either
only grape or grape and oak tannins. It is one of the most challenging things to taste the difference between oak tannins and grape tannins, so dont worry if you dont get it right away
How and Why Wine Ages
Aging is most noticeably the process of the tannins in the wine reacting with other components until they are unable to stay in solution, where upon they become sediment (precipitation). While this is happening, the aromas of the grape are replaced by the bouquet of the aged wine (reductive aromas). At the same time, the color in the wine either lightens if it is a red wine (the anthocyanins - red pigments - bond to the sediment) or in white wine the color turns brown (oxidizes, just like a bite out of an apple - reds do this too, but it is harder to see).
So a hard, tannic red wine will, with luck, become softer in the mouth; less fruity, and more wood/leather in the nose, and generally more complex and full of nuance as it ages. An oaky white wine will become less fruity in the nose, more golden in color, and more complex and subtle in the taste (more caramel and less fruit flavors).

It is impossible to make general rules about how long any given wine will age. For example, while it is certain that many Cabernet Sauvignons will indeed age 5-7 years, there are plenty that will not age at all (the fruitier, less expensive styles) and more that will age for decades (the richer, more expensive selections).

The factors that allow a wine to age are quite complex, but here are a couple of rules of thumb:
       The wine must have a fairly high level of Tannin to age at all.
       All the tannin in the world is no good if the wine has no Acidity to keep it fresh tasting.
       Acidity and tannin are all well and good, but it is fruit that makes wine taste good, and if there is not enough fruit in the wine, then when it ages it will taste like nothing.
       The fuller a wine in all 3 of these components, the longer it will age.
       The tannins can either come from the grapes themselves (skins and seeds) or (especially in the case of white) from being aged in wood, usually oak. Grape tannins are more subtle, but often as strong, and rarely as astringent (mouth drying) as oak tannins. Grape tannins are better than oak when it comes to aging, hence grapes like Cabernet Sauvignon, with thicker skins, tend to have better aging potential.
       The acidity, while it can be added (illegal in many parts of the world), like the fruit, primarily comes from the grape itself. Acidity can be balanced in the winemaking process, but the best vintages have a perfect balance of tannin, fruit and acidity, in the grape itself.
       More generalities: Cab ages best. Pinot ages surprisingly well, if it is a great Pinot. Chardonnay, when it is oaky, not only ages, but really needs a few years to even out. Merlot needs high levels of Cab in the blend to age well, Syrah rarely ages particularly well, except for true Rhones.
Oak derived flavors and aromas.

Heavy Toast contributes caramelized,
smoky, burnt and toast flavors
Heavy toast French oak imparts
cinnamon, ginger and clove with undertones of crème brulee, bitter cocoa, charcoal and roast coffee character. French oak often develops a very cedary aroma.
Heavy toast American oak imparts a heavy campfire/roasted coffee note with a strong vanilla signature
Heavy toast Hungarian oak impart a heavy vanilla note with spicy, molasses undertones
Medium Plus Toast imparts aromas of honey, roasted nuts, toasted bread, and baking spices. They lack the black spice and char tones of heavy toast yet remain very assertive.
Medium Toast imparts more spicy, woodsy tones to the wine and the effects are perceived more easily on the nose then on the palate.
Medium toast French oak imparts
cigar box, cedary, creamy tones to the wine with toasty notes
Medium toast American oak imparts cafe au lait and coconut tones with a strong vanilla
signature
Medium toast Hungarian oak
imparts a vanilla note with spicy, earthy undertones
Light Toast raw wood, coconut and dill

Light toast French oak imparts notes
of vanilla, raw wood shavings and sweet caramel notes

Light toast American oak imparts coconut and dill notes with raw wood tones

Light toast Hungarian oak imparts a light vanilla note with spicy, herbal undertones
Aromas associated with oak

HERBACEOUS: Weedy, Dill, Mown Hay, Menthol, Grass, Tobacco.
WOODY: Cedar, Sawdust, Pencil Shavings, Sappy, Green, Pine, Tar,
Resin.
 SPICY: Clove, Cinnamon, Coconut, Vanilla.
Aromas that can develop in oak during the toasting process.

SMOKY: Barbecue, Wood Smoke, Burnt Sugar.
SWEET: Brown sugar, Barbeque Sauce, Maple Syrup, Butterscotch, Molasses, Honey, Toffee, Marshmallow,
CREAMY: Lactic, Butter. Cream
YEASTY: Popcorn, Cookie Dough. Baked Pastry Dough
ROASTED:, Graham Cracker, Toasted Bread, Coffee, Cereal, Caramel
NUTTY: Hazelnut, Walnut, Almond,
SPICY: Nutmeg, Dried Ginger, Cigar Box
Alcohol:
Alcohol can sometimes tell us the intensity of a wine and the ripeness of the grapes that went
into making the wine.
Alcohol level
 can add quite a bit of body, spiciness and texture to wine.
Alcohol Ranges
 from 5% ABV 16% ABV. Fortified wines are 17-21% ABV.
Alcohol Level
 directly correlated to the sweetness of the grapes prior to fermenting the wine.
Warmer growing regions
 produce sweeter grapes which have the potential to make higher alcohol wines.
Low vs. High Alcohol Wine
 Neither style is better than the other, its simply a characteristic of wine.
Body:(Light Medium Full)
Body can give us clues to the type of
wine, the region it was grown and the possible use of oak aging.
Body is the culmination of all of the aforementioned wine characteristics as well as the profile of the taste from start to finish. You can categorize wines based on their body to make it easier to find and discover what you like. For example,
Syrah tastes very full-bodied up front and typically has a very subtle finish, whereas Nebbiolo starts out light and bright and builds to more intense tannin as the flavor evolves in your mouth.

DECANTING WINE:LẮNG RƯỢU VÀ AERATING WINE: LÀM CHO RƯỢU THOÁNG KHÍ

     Decanting wine : Lắng rượu and Aerating wine: Làm cho rượu thoáng khí

      Vào thời kỳ mà các quy trình tinh lọc rượu chưa được hoàn hảo như hiện nay ,thì phần lớn các chai rượu vang chủ yếu là vang đỏ đều bị có cặn, cặn chủ yếu được tạo ra từ chất tannin và 1 dạng cặn giống như muối là do muối và axit tạo thành khi chưa được lọc hết và khi gặp nhiệt độ lạnh sẽ được sinh ra, lưu ý điều này không làm ảnh hưởng đến chất lượng rượu vang.Đương nhiên người ta không thể uống một chai rượu vang có cặn khi chúng chưa được lắng.Đối với rượu vang đỏ ,việc cấu thành cặn hoàn toàn là một hiện tượng tự nhiên :đây là dấu hiệu của sự xuống màu rượu.Đồng thời,điều đó hoàn toàn bình thường đối với vang đỏ có nhiều chất tanin sau khi chúng đã được đóng vào chai từ 6 đến 8 năm.Nếu cặn bị hòa lẫn trong chai rượu hoặc trong ly rượu rót sau cùng ,sẽ làm mất vị ngon của rượu.Do đó ,việc lắng cặn là một quy trình giúp tách cặn ra khỏi rượu và ngoài ra còn làm cho rượu được thoáng khí và tạo điều kiện để cấu trúc hoa quả và các hương vị khác được tỏa ra làm cho rượu được tròn hơn, cân bằng hơn…

Những loại vang nào phải lắng cặn ?
Những loại vang đỏ chất lượng tốt để lâu năm thường sẽ có cặn.
Tuy nhiên cần lưu ý loại rượu vang lâu năm được bảo quản nhiều năm trong hầm tối, hương vị được hình thành dần dần trong chai ở môi trường thiếu khí.Vì vậy đôi khi việc lắng cặn và tạo dưỡng khí có thể làm giảm hoặc làm mất đi hương sắc rất tinh tế nhưng cũng dễ bị tổn thương của rượu.Do đó ,phải rất cẩn thận trong khi thực hiện công việc này. Chúng ta phải biết được cấu trúc và chất lượng cũng như tuổi của nó để decant trong bao lâu. Thậm chí không cần decant.
Những  loại vang đỏ trẻ mạnh có độ chát cao, chúng ta cũng nên rót ra bình để vang trở nên mềm hơn, cân bằng hơn.Và ở đây chúng ta có thể sử dụng kiểu Aerating có nghĩa là vang thực sự chưa có cặn nên chúng ta rót ra bình lắc manh trong vài phút hoặc dùng 1 số dụng cụ để cho rượu thở nhanh hơn ví dụ như Vinturi…Chú Ý tránh dùng cái này cho vang lâu năm.
Những loại vang trắng có chất lượng ngon cấu trúc tốt, nhất là những chai vang trắng Grand Cru hay những chai vang Chardonnay ngon ủ trong thùng gỗ sồi, những chai vang kiểu Orange wine( Vang trắng được ngâm với vỏ nho) có cấu trúc tốt cũng cần phải decant. Và ly dùng cho các loại vang trắng này nên phải là những ly vang có bầu to kiểu burgundy glass hay tương tự.
Thậm chí những chai Champagne ngon lâu năm nên được phục vụ vào ly vnag trắng thì mới thể hiện được hết các hương, mùi  vị cũng như cấu trúc của nó.

Phải lắng cằn rượu khi nào ?
Thời gian lắng là bao lâu không có công thức chính xác nó phụ thuộc vào sự am hiểu của người dùng để áp dụng cho từng chai vang vì tùy vào cấu trúc, năm sản xuất và tuổi của vang…
Lắng cặn rượu như thế nào ?
Nhẹ nhàng mang chai rượu và giữ nguyên tư thế khi nó được để trong hầm rượu (tư thế nằm nghiêng sau đó đặt lên bàn.)
Mở nút chai nhưng không lắc mạnh.
Lấy bình có quai, đem tráng qua nước ấm trước, sau đó tráng lại bằng một ít rượu vang.
Một tay cầm bình, một tay cầm chai rượu.
Rót nhẹ nhàng từ chai sang bình theo thành bình.Có thể thắp thêm ngọn nến để nhìn thấy dòng chảy của vang khi cặn chuẩn bị chảy ra thì dừng rót.

Trên đây là 1 vài dòng chia sẻ để các bạn đỡ thắc mắc.
Nếu có thêm đóng góp ý kiến gì các bạn comment thêm nhé.


Thank you.
