Helpful Wine Terminology So You Sound Like You Know What You’re Talking About

There’s always something to be learned in the vast world of wine. Knowing a bit of the language will keep you from getting lost in translation and potentially buying something you might not like. Plus, you’ll sound informed the next time you’re in a tasting room.

So, while you study up on outstanding regions like Alto Adige and unique styles like White Pinot Noir, pack this handy term guide with you. It might just expose you to your new favorite bottle or producer.


An ancient clay vessel used to ferment or age wines, famously utilized by Georgians thousands of years ago and re-emerging as a style today. Read more about it here.

The age-old trade of barrel building, which involves all of the cool things (fire, wood, and hammering).


Adding yeast to fruit, often done togain more control over fermentations or for flavor reasons. Most who add yeast use commercial strains. 


The gunky-looking stuff at the bottom of a tank or barrel. It’s essentially spent yeast cells and other particles. Aging sur-lie means leaving the wine on this material instead of racking it off (more on that soon).


The young grape juice, skins, seeds, and stems before it ferments into wine.

Native Yeast

The naturally occurring yeast on the fruit itself that can spark a wild (also called natural or spontaneous) fermentation.

Vine-eating blight caused by insects, an epidemic that nearly wiped out all of Europe’s vineyards not too long ago. Read all about it here.


Breaking down the cap, or solid mass at the top of a fermentation vessel, allowing the wine to circulate and keep the cap wet and integrated. Also, a great way to build your triceps during harvest. Some winemakers prefer to cycle the wine over via a pump.


The bump at the base of the bottle, a feature full of theories. Most likely created to settle out solids, make it easier to ship, and help with the overall integrity of the bottle.

Reverse Osmosis

Essentially a sophisticated version of filtration (so fine we’re talking molecular) used to adjust alcohol content, address smoke impact, and more.

The best way to open a bottle of bubbly, period. Made famous by Napoleon and a surefire way to win over everybody at your next party. You can learn more about it here.

Smoke Taint

The poorly named title for wine negatively affected by smoke from fires. We suggest “smoke impact” in its place.


Sulfur dioxide, which occurs naturally and is often added in the process to prevent spoilage. Read all about ‘em here.


The mouth-drying, structure-enhancing stuff that comes from the stems, seeds (aka pips) and skins of grapes.

Adding wine to barrels occasionally to keep them full and prevent oxidation. What’s evaporated is often called the angel’s share.

Whole Cluster

The wine-opening contraption with the funny screw and typically a knife built in.
