Regardless of whether you’re an experienced oenophile or a wine scene newbie, attending wine tasting events is the perfect way to get a feel for what you love and what you don’t. You can try a wide range of different vinos without buying a whole bottle and wine tastings aren’t typically uber expensive, so it’s a win-win.

Wine tasting etiquette is easy to grasp — and you don’t need to learn a whole new language to talk about different wines. That said, there are certain things you should refrain from saying at a wine tasting event. It’s not important that you come off as an expert, but you really don’t want to look like a jackass. Find out now what not to say at your next wine tasting event.

1. “I don’t drink screw-cap wines”

According to Blog Your Wine, saying that you don’t drink wines with screw caps is a common faux pas at wine tastings. And it’s one that makes you look like you know absolutely nothing about wine. Screw-top wine bottles are perfectly fine — in fact, because corks deteriorate over time, some wineries actually reseal their bottles with screw caps instead of corks when it’s time to recork older vintages.

2. “Which type of barrel was this wine aged in?”

First, says Blog Your Wine, who cares what kind of barrel the wine was aged in? If it tastes great, it really doesn’t matter. Saying this will make you sound pretentious. FYI, different types of oaks can affect wines. For instance, American oak typically gives a more intense flavor than French oak, which provides a more subtle taste.

3. “What percentage malo is this wine?”

Malolactic fermentation, known as malo, turns the tart malic acid in wine into a softer-tasting, lactic acid. Winemakers decide what results they want, then tailor the degrees of malo they put a wine through to match that, according to Blog Your Wine. They typically put red wine through a full malo, but they put white wines through different levels of malo depending on their preferences. Don’t ask how much malo the wine went through — the server won’t know, and you don’t need to know.
