What Are Wine Diamonds? A Sparkling Surprise in Your Glass!

If you’ve ever noticed small, crystal-like bits at the bottom of your wine glass or bottle—don’t worry, your wine hasn’t gone bad. In fact, you’ve just discovered something kind of magical: wine diamonds.

So, What Exactly Are Wine Diamonds?

Wine diamonds, also known as tartaric acid crystals or tartrates, are a completely natural byproduct of winemaking. Tartaric acid is one of the main acids found in grapes, and when a wine is chilled (either during production or after bottling), it can cause the tartaric acid to solidify and form tiny, harmless crystals.

They’re not sugar, they’re not glass, and they definitely don’t mean your wine is flawed. In fact, the presence of these diamonds often indicates a wine that has been made with minimal processing—something many wine lovers actually prefer.

A Natural Occurrence in Our La Crescent

You may spot these sparkling wine crystals in our La Crescent, a bright and aromatic white wine known for its vibrant citrus and floral notes. Because we keep our wines as close to their natural state as possible, La Crescent can sometimes show off these wine diamonds—especially if it’s been stored in cooler temperatures.

Rather than filter them out with heavy processing, we let nature shine. Wine diamonds are simply a sign of purity and quality, adding a little extra sparkle to your sipping experience.

Should You Be Concerned?

Not at all. Wine diamonds are completely safe to drink and tasteless, though you can easily avoid them by pouring carefully or decanting. Some people even consider them a badge of honor—a tiny reminder that good wine is a product of real grapes, crafted with care.

So the next time you pour a glass of La Crescent and see a few crystals at the bottom, raise a toast to nature’s own wine glitter.

Curious to try it for yourself? Stop by the tasting room and ask for a pour of La Crescent. Who knows—you might just find a few wine diamonds waiting at the bottom of your glass.
