The Ultimate Chocolate Storage Guide 🍫

You just got your hands on some amazing chocolate. Score! Perhaps you chose our organic dark chocolate bars, or maybe you decided to go wild and grab a stash of our organic chocolate truffles. You're riding high on excellent life choices. 

But then—plot twist—you find your chocolate covered in white spots and/or a chalky texture. 

No need to worry! That is NOT mold, and your chocolate is not ruined and still safe to consume. It’s just in a state of bloom. 

Why Does Chocolate Get That Weird White Stuff? {#bloom-explained} 

Do you see a white to grayish coating on your chocolate? It’s called bloom, and there are two types–both completely harmless. 

Fat bloom happens when cocoa butter separates from the chocolate due to heat exposure or temperature swings, leaving a dusty white layer on the surface. Think of it like oil separating in natural peanut butter—annoying to look at, but perfectly fine.  

What causes fat bloom?

• Storing chocolate above 75°F (24°C)
• Temperature fluctuations when moving chocolate between hot and cold environments
• Poor tempering during manufacturing (rare with our Swiss chocolate)
• Melting and re-solidifying without proper tempering 

This is especially common with high-quality dark chocolate that has a high cocoa butter content and zero stabilizers or artificial ingredients—like everything we make. 

Sugar bloom occurs when moisture dissolves the sugar on the chocolate's surface. When that moisture evaporates, it leaves behind larger sugar crystals that create a grainy, white appearance. 

What causes sugar bloom? 

Sugar bloom is especially sneaky because it can happen during manufacturing if chocolate is exposed to damp air, or at home if moisture gets trapped in the wrapping. 

The Golden Rules of Chocolate Storage {#storage-rules} 

1. Keep It Cool (but not too cool!) 

Chocolate has standards. Too warm? It melts. But too cold? You get condensation and sugar bloom. At Alter Eco, we make chocolate without soy lecithin or artificial preservatives, which means our products are more temperature-sensitive compared to other chocolate brands with these ingredients. 

The sweet spot for storage at home is 60–70°F (15–21°C). When temperatures go higher or start fluctuating, that's when melting or bloom can happen. 

Temperature breakdown: 

When to use the fridge: Only refrigerate chocolate if the room temperature consistently exceeds 75°F or if your chocolate is actively melting. If you do refrigerate it, wrap it tightly in plastic wrap or aluminum foil first, then let it come back to room temperature before unwrapping. This prevents condensation from forming on the chocolate. 

2. Keep It Dry 

Moisture is chocolate's sworn enemy. Even a little humidity can cause sugar bloom or make your chocolate go soft and sticky—definitely not the vibe you're going for! 

The fix? Store your chocolate in a cool, dry place. If you have a device to measure relative humidity (RH) at home, we recommend storage at <65% RH. The lower the better though, around 50-60% RH. Think pantry or cupboard, far away from: 

💧 If you live in a humid climate: Please keep our chocolate in the original wrappers, and place in an airtight container (glass or plastic both work). You can also add a food-safe silica gel / desiccant packet to the container if you have it, or even a small pouch of dry rice works instead! Then the container can be stored in a cool, dry place. 

3. Keep It Dark 

Why darkness matters: Light can degrade chocolate over time through a process called photo-oxidation, affecting both flavor and texture. Think of it like how colors fade in direct sunlight—except with chocolate, the flavor fades too.  

This is why quality chocolate often comes wrapped in foil or opaque packaging. Once you've opened your chocolate bar, we recommend that you keep it wrapped or store it in an opaque, airtight container away from light. 

4. Keep It Sealed 

The odor absorption problem: Chocolate's cocoa butter acts like a flavor sponge, readily absorbing surrounding odors. Ever had chocolate that tastes vaguely like onions? Yeah, that's why proper sealing matters. 

Best practices: 

Our compostable truffle wrappers aren't just better for the planet—they're also designed to protect flavor until you are ready to devour them. 

What About Refrigerating & Freezing Chocolate? 

The short answer: Only refrigerate or freeze chocolate when absolutely necessary! 

When to refrigerate: 

How to refrigerate properly: 

Freezing: The Long-Term Storage Solution 

You can absolutely freeze chocolate if you're trying to extend its shelf life for several months. Or if you bought way too much during a sale and need to hide the evidence from yourself for a while. No judgment! 

Step 1: Pre-wrap preparation 

Step 2: First layer (moisture barrier) 

Step 3: Second layer (odor protection) 

Step 4: Freezer placement 

Thawing frozen chocolate gradually (which prevents condensation and bloom): 

Pro tip: Frozen chocolate is also excellent for eating directly from the freezer if you like your chocolate extra-crunchy and cold. Try our organic Mint Crème Truffles frozen for a refreshing treat that's like chocolate ice cream, but better! 

How Long Does Different Chocolate Actually Last? {#shelf-life} 

Chocolate shelf life varies significantly based on type, ingredients, and storage conditions. Here's what you need to know: 

Dark Chocolate (>60% Cacao): 

Milk Chocolate (10-50% Cacao): 

Filled Chocolates & Truffles: 

Understanding Best If Used By Dates 

Important: Best by / best if used by dates are quality indicators, not safety deadlines. 

At Alter Eco, our chocolate is made with simple, organic ingredients and zero artificial preservatives, which means our chocolate is at its absolute best when fresh. Check the "best by" date on the package, and try to enjoy it within the first 3 months of purchase for peak flavor and texture. Though honestly, we've never had chocolate last that long around here. 

What If Your Chocolate Already Bloomed? {#bloom-fix} 

Don't throw it away! Bloomed chocolate is perfectly safe to eat—it just won't look Instagram-worthy. 

Option 1: Remelt It (Chocolate Makeover) 

Real talk: The re-melted chocolate won't have that perfect snap of properly tempered chocolate, but it'll taste just fine and look way better than the bloomed version. 

Option 2: Bake With It (Chocolate's Second Act) 

Use bloomed chocolate for baking—once it's melted into cookies, brownies, or hot chocolate, nobody will ever know it had bloomed in the first place.

Option 3: Just Eat It (The Pragmatic Approach) 

Bloomed chocolate is completely safe to eat. The flavor is usually still good—the texture might be slightly grainy or less smooth, and the taste can seem less fresh. But if you're not too concerned about appearance, just enjoy it. 

Signs Your Chocolate Has Actually Gone Bad 

Bloom is totally fine. But there are a few signs that mean your chocolate has actually spoiled and should be tossed: 

🚫 Real Mold Growth 

🚫 Rancid or Sour Smell 

🚫 Off-Putting Taste 

🚫 Insect Infestation (rare but possible in certain climates) 

A Special Note About Shipping & Retail Storage 

Ever bought chocolate online or from a store, only to find it was already bloomed when you opened it at home? This is frustratingly common, especially during warmer months of the year. 

 Chocolate is exposed to warmer or fluctuating temperatures during shipping or while sitting on a retailer's shelf. Even brief exposure to heat can cause melting or bloom.  

 For best results: 

The Bottom Line 

Storing chocolate properly comes down to maintaining four key conditions: 

Remember: Bloom is totally safe—melt it, bake it, or eat it as is. Real problems show up as fuzzy mold, rancid smells, or off tastes. Life's too short for chocolate mishaps!

Ready for Perfectly Stored Chocolate? 

Now that you know how to store chocolate like a pro, there's only one question left: What are you going to do with all that perfectly preserved chocolate? 

Our vote: Eat it! Preferably today. Because while proper storage extends chocolate's life, delayed gratification is overrated.
