What's the real difference between A1 and A2 ghee?
A1 and A2 refer to beta-casein protein types in cow milk:
A2 ghee: From desi cows (Rathi, Gir, Sahiwal) with beta-casein A2 protein
A1 ghee: From foreign/crossbred cows (Jersey, Holstein) with beta-casein A1 protein
Key Difference: During digestion, A1 protein breaks down into BCM-7 peptide, linked to bloating and inflammation. A2 protein doesn't produce BCM-7, making it easier to digest for 60-70% of people.
The harsh reality? Most "A2 ghee" brands in India are fake. Here's how to spot the real thing.
Let me be honest with you.
Six years ago, when I left my engineering job to start farming, I had no clue what A1 or A2 meant. I just knew my grandmother's ghee tasted different from the store-bought stuff.
Now, after raising 40+ Rathi cows and making thousands of kilos of ghee, I've learned something that the big brands don't want you to know.
The A1 vs A2 debate isn't about marketing. It's about biology.
And most people are getting it completely wrong.
Understanding A1 and A2 Proteins: The Science Made Simple
Here's the thing nobody explains properly.
All cow milk has a protein called beta-casein. It makes up about 30% of the total protein in milk. But this beta casein comes in different versions - like how humans have different blood groups.
The two main versions are:
Beta-casein A1: Found in European/crossbred cows
Beta-casein A2: Found in Indian desi cows
The difference? Just one amino acid at position 67 of the protein chain.
Sounds tiny, right? But that single change makes a huge difference in how your body handles the milk.
How A1 and A2 Digest Differently in Your Body
When you eat A1 ghee (or drink A1 milk), your digestive enzymes break down the beta-casein A1 protein. During this breakdown, a peptide called Beta-Casomorphin-7 (BCM-7) gets released.
BCM-7 is the troublemaker.
According to research published in PMC's peer-reviewed database, BCM-7 from A1 milk digestion can: Slow down gut movement (leading to constipation, bloating)
Trigger inflammatory responses in sensitive individuals
Cross the gut barrier and potentially affect other body systems
Act as an opioid-like peptide affecting digestion
A2 protein doesn't break down into significant BCM-7. It produces different peptides that your body handles much better.
Think of it this way: A1 is like a lock that your body struggles to open. A2 is a lock your body has the perfect key for.
Real Customers, Real Differences: What I See on My Farm
I've had over 200 customers switch from regular ghee to our Rathi cow A2 ghee. And the feedback? Consistent.
Mrs. Kapoor from Delhi messaged me last month: "I've been lactose intolerant for 10 years. Avoided all dairy. Tried your ghee nervously. Zero bloating. Zero discomfort. How is this possible?"
It's not magic. It's A2.
The digestive comfort difference is real. A study on digestive health and BCM-7 found that about 60-70% of people who report "lactose intolerance" actually have trouble with A1 protein, not lactose. When they switch to pure A2 dairy, the problems vanish.
But here's what frustrates me.
The Massive Lie the Industry is Telling You
Walk into any grocery store. You'll see dozens of brands screaming "A2 GHEE!" on their labels. I tested 8 of them. Want to know how many were actually pure A2?
Two. Just two.
The rest? Mixed. A1-A2 hybrid milk. Or straight-up A1 milk with "A2" printed on the label because there's no strict regulation.
Why Fake A2 Ghee is Everywhere
Foreign cows (Jersey, Holstein-Friesian) give way more milk. 20-30 liters per day. Our Rathi cows? 6-8 liters max.
For a company trying to maximize profit, the temptation is huge. Mix in some Jersey milk, nobody can tell by looking, price it as "pure A2," and make 3x the margin.
The customer? They think they're getting health benefits. They're not.
How to Identify Real A2 Ghee: The 5-Point Verification
After six years of farming and countless conversations with dairy scientists, here's what I've learned.
1. The Breed Matters (This is Non-Negotiable)
Only Indian indigenous breeds produce pure A2 milk. Studies by NBAGR (National Bureau of Animal Genetic Resources) confirm that five high-yielding Indian dairy breeds have 100% A2 allele:
Pure A2 Breeds:
Rathi (Rajasthan)
Gir (Gujarat)
Sahiwal (Punjab)
Red Sindhi (Sindh/Rajasthan)
Tharparkar (Rajasthan/Gujarat)
A1 Producers (Foreign breeds):
Jersey (from Channel Islands)
Holstein-Friesian (from Netherlands)
Brown Swiss (from Switzerland)
Crossbreeds? They produce mixed A1-A2 milk. Not pure A2.
Red flag: If a brand can't tell you the exact cow breed, run away. "Indian cow" is not enough. "Desi cow" is too vague.
2. The Price Will Tell You the Truth
Let me break down real numbers from my farm.
To make 1 kg of ghee, I need:
25-30 liters of Rathi cow milk (₹70/liter) = ₹1,750 to ₹2,100
Hand-churning labor (4 hours) = ₹200-300
Slow-cooking on wood fire (6 hours) = ₹100-150
Glass packaging + lab testing = ₹150-200
Total production cost: ₹2,200 to ₹2,750 per kg
We sell at ₹1,699 per kg. Yes, we're selling below cost to build the brand. Most honest A2 ghee producers sell at ₹1,800-2,500/kg.
Now tell me - how is someone selling "A2 ghee" at ₹599 per kg?
They're lying. Period.
Either it's A1 milk, or it's machine-made from mixed-breed cows, or it's adulterated. There's no fourth option.
3. Ask for the Lab Report (Most Won't Have It)
Real A2 ghee producers test their milk for beta-casein type. It's called A1/A2 genotyping and costs about ₹3,000-5,000 per test.
We test every quarter. Our reports consistently show <1% A1 protein (some trace amounts always show up in any test).
Ask your brand: "Can I see your latest A1/A2 genotyping report?"
Watch them scramble.
4. Check the Texture and Color
Real A2 bilona ghee has:
Grainy, crystalline texture when semi-solid
Deep golden-yellow color (from beta-carotene in grass-fed diet)
Nutty, aromatic smell (not synthetic)
Slow melting when heated
Fake/mixed ghee shows:
Perfectly smooth texture (machine-made)
Pale yellow or white color
Bland or artificially flavored smell
Burns quickly or leaves residue
5. Trust Your Body's Response
This one takes 2-3 days, but it's the ultimate truth test.
Consume 1-2 teaspoons daily for 3 days.
Real A2 ghee response:
Easy digestion, no bloating
No gas or acidity
Increased energy
Better bowel movements
Fake A2 (actually A1) response:
Digestive discomfort
Bloating or heaviness
Feels hard to digest
Body tells you something's wrong

The Lab Testing Process: How A2 is Verified
Many customers ask: "How do you actually test for A2?"
Here's the scientific process:
Step 1: Sample Collection
Milk sample (5-10ml) or blood sample from cow
Must be from individual cow (not mixed herd milk)
Step 2: DNA Extraction
Beta-casein gene (CSN2) is isolated
Located on chromosome 6 in cattle
Step 3: Genotyping Analysis
PCR (Polymerase Chain Reaction) amplification
Identifies amino acid at position 67
Histidine (His67) = A1
Proline (Pro67) = A2
Step 4: Result Classification
A1A1: Produces only A1 milk
A2A2: Produces only A2 milk (what we want!)
A1A2: Produces mixed milk (not pure A2)
Where to Get Testing Done:
NBAGR, Karnal (₹3,000-5,000 per sample)
NABL-accredited private labs
Some universities with dairy science departments
At Ratnaya Organics, we test our entire herd every 6 months. Our latest report (November 2024) shows 98.7% A2 genotype across all our Rathi cows.
Health Claims: Separating Science from Marketing Hype
Let me separate hype from truth.
What Science Actually Supports:
✅ Digestive comfort: Strong evidence. Multiple clinical studies show reduced bloating, gas, and stomach discomfort with A2 dairy.
✅ Inflammation markers: Moderate evidence. Some research suggests lower inflammatory responses with A2, but more studies needed.
✅ Easier on sensitive systems: Strong anecdotal evidence from thousands of customers worldwide, including ours.
What's Overblown Marketing:
❌ "A2 cures diabetes/heart disease/cancer": No. Stop. There's no evidence for this. Anyone claiming A2 ghee cures diseases is selling snake oil.
❌ "A1 is toxic": Too strong. A1 isn't poison. It's just harder for many people to digest. Some people handle it fine.
❌ "A2 is ancient Ayurvedic": Ayurveda didn't distinguish between A1 and A2 because A1 cows didn't exist in India until the British brought them. Ancient ghee was A2 by default, not by choice.
Why I Only Farm A2 (And Why It's Harder)
People ask me: "Why not just buy a Jersey cow? You'd make 3x more milk."
Simple answer: I left engineering to make real food, not fake products.
Longer answer: Farming A2 is significantly harder.
Our Rathi cows are heat-adapted, perfect for Rajasthan's brutal 48°C summers. But they're stubborn. They produce less. They need specific care. They bond with specific farmers (our cow Kamla literally refuses to give milk if her favorite farm hand isn't around).
But when I churn that milk at 3 AM, and the ghee starts forming, and that aroma fills the entire farm?
That's the smell my grandmother's kitchen had.
That's the ghee Ayurveda talked about. That's what real food smells like.
You can't fake that with A1 milk. You just can't.
The Question You Should Actually Ask
Here's what matters more than A1 vs A2:
Is your ghee from happy, well-treated cows eating good food?
I've seen A2 farms where cows are crammed in sheds, fed commercial cattle feed, never seeing grass. That ghee might technically be A2, but it's not quality.
Our Rathi cows graze on 110 acres. They eat bajra, jowar, natural grass. They're not pumped with oxytocin for more milk. They're milked once daily, and we leave enough for their calves.
That matters more than the protein type.
A1 ghee from happy, grass-fed Jersey cows is better than A2 ghee from abused, feed-lot Gir cows. But the best? A2 ghee from happy, grass-fed indigenous cows.
That's what we make.
Is A2 Ghee Worth the Premium? Your 3-Point Decision Guide
For us? We can't make it any cheaper. The math doesn't work.
For you? Depends on three things:
1. Do you have digestive issues with regular dairy?
Then yes, absolutely try A2. The difference might change your life. 60-70% of people with "lactose intolerance" actually react to A1 protein.
2. Do you want to support indigenous cow breeds?
Foreign cows are pushing our Rathi, Gir, and Sahiwal cows toward extinction. Every purchase of real A2 ghee helps preserve these breeds.
3. Do you care about taste and tradition?
A2 ghee from bilona method tastes like ghee used to taste. If that matters to you, it's worth every rupee.
If you're just buying ghee for basic cooking and have no digestive issues? Regular ghee is fine. Don't overspend on fake "A2" brands just for a label.
How to Start Your A2 Journey (Without Getting Cheated)
Step 1: Try a small quantity first. Don't buy 5 kg immediately. Get 250-500 grams. Test it.
Step 2: Check these markers:
Grainy texture when semi-solid (sign of hand-churning)
Deep golden color (sign of A2 + grass feeding)
Nutty aroma (not synthetic smell)
Slow melting when heated
Step 3: Notice how your body responds. Less bloating? Better digestion? That's your answer. Step 4: Ask the seller uncomfortable questions:
What's your cow breed? (Specific name required)
How much milk do your cows give daily? (If they say 15+ liters, it's not pure indigenous) Can I visit your farm? (Real farmers will say yes)
Where's your lab report? (Real producers have them)
Step 5: Trust your gut. If something feels off about a brand, it probably is.
Frequently Asked Questions (FAQ)
Q: Is A2 ghee better than A1 ghee for weight loss?
A: No special advantage. Both have identical calories (~900 kcal per 100g). A2 might help if digestive issues were preventing nutrient absorption, but it's not a weight loss miracle.
Q: Can diabetics consume A2 ghee?
A: Ghee (A1 or A2) has minimal impact on blood sugar as it's pure fat. Diabetics can consume it in moderation (1-2 tsp daily), but it doesn't "cure" diabetes. Consult your doctor.
Q: Is A2 ghee safe for babies?
A: Yes, after 6 months of age, in small quantities (1/4 tsp initially). A2 is gentler on developing digestive systems. But always introduce gradually and watch for reactions.
Q: How long does A2 ghee last?
A: Properly stored (airtight glass container, away from moisture), pure ghee lasts 12-18 months at room temperature. No refrigeration needed.
Q: Why is some A2 ghee grainy and some smooth?
A: Grainy texture = hand-churned bilona method (traditional). Smooth texture = machine-made. Both can be
A2, but bilona preserves more nutrients and taste.
Q: Can I test A2 ghee at home?
A: Not accurately. A1/A2 testing requires lab genotyping (₹3,000-5,000). At home, you can only test purity (not protein type). Trust the source.
The Bottom Line: Don't Pay Premium for Fake Labels
A1 vs A2 isn't about one being "poison" and the other being "nectar." It's about biology, digestibility, and choosing what works for your body.
Most Indians handle A2 better because our ancestors consumed it for thousands of years. Our systems evolved with it.
But the real crime? Companies exploiting this knowledge to sell fake products at premium prices.
If you're going to pay extra for A2 ghee, make sure it's actually A2.
Ask questions
Demand transparency
Support farmers who are honest about their process
And if a brand can't answer basic questions about their cows?
They don't deserve your money.
We've been making ghee the same way for six years now. Same cows. Same village. Same bilona method. Some days I wonder if there's an easier way.
Then I taste the ghee.
And I remember why I started this journey.
