How to Fix Chocolate Bloom on Your Taza Bars

Quick answer

If your Taza bar has white spots or a dusty film, it's likely chocolate bloom—harmless and fixable. You can salvage it by gently melting and re-tempering, or simply enjoy it as is. To prevent it, store chocolate between 60-70°F in a cool, dry place away from light. If you see fuzzy mold, throw it out.

You unwrap your Taza bar and spot white patches or a grayish film. Before you panic, know that this is usually chocolate bloom—a natural cosmetic change that doesn't make the chocolate unsafe to eat. Bloom occurs when cocoa butter or sugar migrates to the surface, and it's completely harmless.

In this guide, we'll walk you through how to fix chocolate bloom on your Taza bars, how to tell it apart from mold, and the best way to store chocolate to avoid it in the future.

Why does chocolate turn white?

Chocolate bloom is the culprit behind those white spots. There are two types: fat bloom and sugar bloom. Fat bloom happens when the chocolate gets too warm and the cocoa butter melts, then re-solidifies unevenly on the surface. Sugar bloom occurs when moisture touches the chocolate, dissolving the sugar, which then recrystallizes as a gritty white layer.

Both types are cosmetic and don't affect taste or safety. They often happen after temperature fluctuations—like leaving a bar near a warm stove or in a sunny spot. Since Taza's stone-ground chocolate has a bold, rustic texture, bloom might be less noticeable at first, but it can still appear.

How to fix chocolate bloom

If you've got a bloomed bar, you can fix it by melting and re-tempering the chocolate. Chop it into small pieces, melt gently over a double boiler (or in short microwave bursts), and then re-temper by cooling it to about 88-90°F while stirring. Pour into molds or a parchment-lined pan and let it set.

This restores the smooth shine and texture. However, for eating straight out of the wrapper, you can simply ignore the bloom—it'll taste the same. Keep in mind that re-tempering is extra work, so if you're not baking or dipping, eating as-is is perfectly fine.

• If you're baking, bloomed chocolate melts fine—just skip the re-tempering and use it directly in your recipe.

Chocolate bloom vs mold: how to tell the difference

Bloom is dry, powdery, and often looks like white dust or irregular spots. Mold, on the other hand, appears as fuzzy patches—usually green, blue, or white—and may have a musty smell. Bloom won't have any odor; mold will.

If you see fuzzy spots or smell something off, don't eat it. Mold is a safety issue, and the bar should be thrown out. When in doubt, trust your senses: if it looks fuzzy or smells bad, discard it.

How to prevent chocolate bloom

The best way to avoid bloom is to store chocolate properly. Keep it in a cool, dry place with a consistent temperature, ideally between 60-70°F. Avoid the refrigerator, because moisture can cause sugar bloom. A pantry or cupboard away from heat sources works well.

Also, keep chocolate tightly wrapped in its original packaging or in an airtight container to protect it from humidity and odors. If you're storing multiple bars, make sure they're not exposed to direct sunlight or fluctuations.

Diagnosis: is your Taza bar okay?

• Symptom: White or gray film, dust-like spots, or a slightly gritty surface on the chocolate. Likely chocolate bloom, not mold.
• Cause: Exposure to heat or moisture—like a warm room or fridge storage—causes cocoa butter or sugar to rise to the surface. Adjust your storage habits.
• Corrective action: If you want to fix it, melt and re-temper the chocolate. Or just eat it as-is—it's safe and tastes the same. Your call: re-temper for perfect shine, or enjoy anyway.
• Stop or discard: If you see fuzzy mold, smell a sour or musty odor, or the chocolate tastes off, throw it away immediately. Don't eat moldy chocolate.

Taza bars that shine with proper care

• Toffee, Almond, & Sea Salt: Perfectly unrefined 60% dark stone ground organic chocolate with a trifecta of tasty: toffee, almonds, and sea salt. The crunchy additions and bold flavor are best enjoyed fresh, so proper storage keeps them from becoming stale or losing their snap.
• Comfort & Joy Sampler: Contains 4 x 1.35 oz Chocolate Discs: Guajillo Chili, Cacao Puro, Cinnamon, and Vanilla. If you're gifting or sampling, keeping the discs in their original packaging protects them from humidity and temperature changes that cause bloom.

Chocolate bloom is a common, harmless quirk of dark chocolate—especially when storage conditions aren't perfect. With a few simple tweaks, you can keep your Taza bars looking as good as they taste. And if you ever spot mold, don't risk it—toss the bar and grab a fresh one.
