Wine Terms Explained: From A to Z

A – Acidity

Technical term: Acidity refers to the tart, crisp quality found in wine, often experienced on the sides of the tongue. It’s a key structural element in wine, often linked to freshness and ageability. Translation: Acidity in wine is what makes it feel refreshing or even a little sour. It’s the zing that makes you want to take another sip! Think of it like the tartness of a green apple.

B – Body

Technical term: Body refers to the weight or fullness of the wine, which is influenced by factors like alcohol level, tannins, and residual sugars. Translation: When we talk about the “body” of wine, we’re referring to how heavy or light it feels in your mouth. A full-bodied wine, like a bold red, feels more like milk or cream, whereas a light-bodied wine feels more like water.

C – Corked

Technical term: Corked wine refers to wine that has been contaminated by a compound called TCA (Trichloroanisole) that can make the wine taste musty or like wet cardboard. Translation: If a wine is “corked,” it doesn’t taste right—it’s like the wine has been ruined by something nasty in the cork, and it can smell musty or stale. It’s definitely not the wine you want to drink.

D – Decanting

Technical term: Decanting is the process of pouring wine from its bottle into another container to separate the wine from any sediment and allow it to “breathe.” Translation: Decanting is just letting the wine sit for a bit after opening it, usually in a fancy glass jug (called a decanter), to help it open up and taste better. It’s like letting a good song play for a while to warm up.

E – Estate Bottled

Technical term: Estate bottled means that the wine was made from grapes grown on the winery’s own land and processed at that same winery. Translation: If you see “estate bottled” on a label, it means the wine comes directly from the winery’s own vineyards, with all the grapes grown right there. It’s like homemade wine but on a bigger scale.

F – Fermentation

Technical term: Fermentation is the process in which yeast converts the sugars in grape juice into alcohol and carbon dioxide, transforming the juice into wine. Translation: Fermentation is what turns grapes into wine. Basically, yeast eats the sugar in the grape juice and turns it into alcohol, which is how wine gets its kick!

G – Grapes (Varietals)

Technical term: Grape varietals refer to the specific types of grapes used to make wine, such as Cabernet Sauvignon, Chardonnay, or Shiraz. Translation: The type of grape in your wine matters a lot. Just like how an apple and an orange taste different, different grapes make different wines. A Shiraz will taste very different from a Pinot Noir.

H – Hang Time

Technical term: Hang time is the period during which grapes are left to ripen on the vine before harvest. The longer the hang time, the more developed the flavours. Translation: Hang time is how long grapes stay on the vine before being picked. More hang time often means sweeter and more flavourful grapes, similar to how fruit gets juicier as it ripens on a tree.

I – Iron Filings

Technical term: Iron filings are tiny particles found in some wines that can give a slight metallic taste. They’re usually not common, but they sometimes appear when wine comes into contact with steel during production. Translation: If a wine tastes a little like metal or nails, it might be due to iron particles. It’s rare, but it can happen.

K – Kosher Wine

Technical term: Kosher wine is wine that has been produced in accordance with Jewish dietary laws, including strict guidelines about how it is made and handled. Translation: Kosher wine is wine made in a very special way, following rules from the Jewish faith. It’s made with extra care and specific rules about cleanliness and ingredients.

L – Lees

Technical term: Lees are the dead yeast cells and other particles left behind after fermentation. Wines are often aged on their lees for added texture and complexity. Translation: Lees are the leftover bits in wine after fermentation. If you see a wine that’s “aged on lees,” it means the wine has spent time with those leftover bits, making it taste richer or creamier.

M – Malolactic Fermentation

Technical term: Malolactic fermentation (MLF) is a secondary fermentation process where harsher malic acid (found in green apples) is converted into softer lactic acid (found in milk), softening the wine. Translation: MLF is a fancy process that turns sharp, tart flavours (like sour apples) into smooth, creamy ones (like butter). It’s what gives wines like Chardonnay that buttery, smooth taste.

N – Nose

Technical term: The nose of the wine refers to its aroma or smell, which plays a huge role in the overall experience of tasting wine. Translation: The “nose” is just a fancy way of saying the smell of the wine. When you sniff a wine, you’re checking out its nose to get a sense of its flavours before even tasting it.

O – Oak Aging

Technical term: Oak aging refers to the practice of maturing wine in oak barrels, which can impart flavours like vanilla, spice, or smoke to the wine. Translation: Oak aging is like giving wine a bath in wooden barrels, which changes its taste. It can make the wine taste richer or give it hints of vanilla, spice, or even smokiness.

P – Phylloxera

Technical term: Phylloxera is a microscopic insect that attacks grapevines, damaging their roots and often causing significant damage to vineyards. Translation: Phylloxera is a bug that destroys grapevines. It caused a huge problem in wine regions a long time ago, almost wiping out many vineyards worldwide.

Q – Quercus (Oak)

Technical term: Quercus is the scientific name for the oak tree, which is commonly used to make barrels for aging wine. Translation: Quercus is just a fancy term for oak, the type of tree used to make barrels that age wine. The oak can add special flavours to the wine as it ages.

R – Residual Sugar

Technical term: Residual sugar is the sugar that remains in the wine after fermentation, contributing to the wine’s sweetness. Translation: Residual sugar is the leftover sugar in the wine that makes it taste sweet. More residual sugar means sweeter wine.

S – Tannin

Technical term: Tannins are natural compounds found in grape skins, seeds, and stems that create a dry, astringent feeling in the mouth. Translation: Tannins are the things that make your mouth feel dry when you drink certain wines. It’s like the feeling you get after eating a strong black tea. Tannins add structure to the wine.

T – Terroir

Technical term: Terroir refers to the unique combination of soil, climate, and vineyard environment that influences the taste of the wine produced in that region. Translation: Terroir is everything about where the grapes are grown—the soil, the weather, and the land—all of it affects how the wine tastes. It’s like how different regions of the world make fruit taste different.

U – Umami

Technical term: Umami is a savoury taste that is one of the five basic tastes, often linked to wines with high levels of acidity or oak. Translation: Umami is the savoury or “meaty” taste you get in some wines, like a rich red wine with lots of depth. It’s that satisfying, mouth-watering quality you might taste in a broth or aged cheese.

V – Varietal

Technical term: A varietal is a wine made primarily from one type of grape, such as Shiraz, Cabernet Sauvignon, or Chardonnay. Translation: A varietal is just a wine made from one type of grape. If it says “Shiraz,” it means it’s made from Shiraz grapes, and it will taste like those grapes.

W – Wine Legs

Technical term: Wine legs are the streaks or droplets that form on the inside of a glass after swirling. They are caused by the evaporation of alcohol and the surface tension between alcohol and water. Translation: Wine legs are the little drips you see running down the side of the glass after you swirl your wine. They don’t really affect the taste, but they can be fun to watch!

X – Xerophytic

Technical term: Xerophytic refers to plants (including grapevines) that are adapted to grow in dry conditions, requiring minimal water. Translation: Xerophytic just means that the plants, like vines, are really good at surviving with little water. They can handle dry, tough conditions.

Y – Yeast

Technical term: Yeast is a microorganism that ferments the sugar in grape juice, turning it into alcohol during the winemaking process. Translation: Yeast is the tiny living thing that eats sugar in grape juice and turns it into alcohol, making the wine alcoholic!
