The Short Answer
Yes, Kettle & Fire is clean. In a grocery aisle filled with "broths" made of salt, yeast extract, and "natural flavors," Kettle & Fire stands out for using actual bones and organic vegetables.
The beef broth uses 100% grass-fed and grass-finished bones, and the chicken broth uses organic free-range bones. Crucially, they are one of the few brands Certified Glyphosate Residue Free, ensuring their sourcing avoids the ubiquitous herbicide found in many non-organic products.
The only "catch" is the texture. Because it is shelf-stable (packaged in a carton), it undergoes high-heat sterilization. This breaks down the gelatin structure, meaning it will not gel in the fridge like homemade broth or frozen competitors (like Bonafide Provisions).
Why This Matters
Real bone broth is a nutritional powerhouse, but the term is loosely regulated.
1. Lead Contamination: Bones sequester heavy metals like lead. If animals feed on contaminated land, that lead ends up in your broth. Sourcing from grass-fed, regenerative farms is the best defense against this.
2. Hidden MSG: Most store-bought broths rely on yeast extract or "natural flavors" to mimic the savory taste of long-simmered meat. These are excitotoxins that can trigger headaches and inflammation in sensitive people. Yeast Extract Vs Msg
3. The Glyphosate Problem: Bone broth is a concentrated product. If the animals ate glyphosate-sprayed grain (or the veggies in the pot were sprayed), you are getting a concentrated dose of pesticides. Glyphosate In Oats
What's Actually In Kettle & Fire
The ingredient list is refreshingly boring. Here is what is inside the Classic Beef Bone Broth:
- Marrow Bones ā Sourced from 100% grass-fed, grass-finished cattle.
- Organic Vegetables ā Carrots, onions, celery, bay leaves, parsley.
- Apple Cider Vinegar ā Organic, used to help extract minerals from the bone. Is Apple Cider Vinegar Healthy
- Spices ā Black peppercorn, rosemary, thyme.
- Sea Salt ā Simple mineral salt.
What's Missing:
- No yeast extract
- No rapeseed or canola oil
- No sugar or caramel color
- No "natural flavors"
What to Look For
Green Flags:
- Grass-Fed & Finished: Ensures the cows weren't fattened on GMO corn or soy before slaughter.
- Certified Glyphosate Free: A third-party verification that is rare in the soup aisle.
- High Protein: Delivers ~10g of protein per serving, confirming a decent bone-to-water ratio.
Red Flags:
- Tetra Pak Lining: While BPA-free, the cartons are lined with polyethylene and aluminum. This is standard for shelf-stable foods but avoids the inert safety of glass.
- Thin Texture: If you are used to "meat jello," this will feel watery. The collagen is present (~5-10g claimed), but the heat processing has denatured the gelatin structure.
The Best Options
If you need shelf-stable convenience, Kettle & Fire is the top choice. If you want maximum gelatin, go frozen.
| Brand | Product | Verdict | Why |
|---|---|---|---|
| Kettle & Fire | Classic Beef/Chicken | ā | Best shelf-stable. Cleanest ingredients and glyphosate-free. |
| Bonafide Provisions | Organic Bone Broth | ā | Best frozen. True gelatinous texture, less processed. |
| Pacific Foods | Bone Broth | ā ļø | Acceptable, but often contains "natural flavor" and lacks density. |
| Swanson | Sipping Bone Broth | š« | Contains yeast extract, sugar, and natural flavors. |
The Bottom Line
1. Buy it for convenience. It is the perfect pantry staple for sipping or quick soups when you don't have 24 hours to simmer bones.
2. Don't fear the liquid texture. It doesn't gel, but independent tests confirm it still contains collagen and amino acidsājust in a hydrolyzed form.
3. Check the label on "Soups." While their bone broths are clean, always double-check the ingredient lists on their pre-made soups (like Tomato or Thai Curry) to ensure they meet your standards, though they generally follow the same strict quality rules.
FAQ
Does Kettle & Fire contain lead?
No concerning levels. Lead in bone broth is a common fear, but Kettle & Fire tests their products and independent reviews (like ConsumerLab) have found they do not exceed strict safety limits for heavy metals.
Why doesn't it gel like homemade broth?
High-heat processing. To make the broth shelf-stable in a carton, it must be heated to high temperatures to kill bacteria. This breaks the protein bonds that create the "jelly" texture, but the amino acids (glycine, proline) are still present.
Is the packaging BPA-free?
Yes. The Tetra Pak cartons are BPA-free. However, they are lined with layers of polyethylene plastic and aluminum to keep the product fresh without refrigeration. If you are strictly plastic-free, stick to homemade or glass-jarred brands. Is Bpa Free Lining Safe
