A2 cow ghee comes from milk that has the A2 type of beta-casein. Many people find A2 desi cow ghee easier on the stomach and less likely to cause bloating. When it is made by the traditional bilona method, the ghee keeps a fuller, natural taste and texture. A2 Farm sells A2 bilona ghee and mentions the breed and method on their product page. 

Look for clear breed and method info on the label, for example Gir or another native breed and the word bilona or curd-churned. Genuine A2 ghee usually has a warm golden color, a nutty smell, and a slightly grainy feel when it cools (Desi Danedar Ghee). Also check for lab reports or test dates on the product page. A2 Farm shows lab reports and source details on their site. 

Gir cow ghee comes from Gir breed cows, which naturally give A2 milk. Gir cow ghee often has a deep golden color, rich aroma, and smooth mouthfeel. People who want authentic a2 gir cow ghee or a2 ghee online look for the breed name and the bilona process to be sure it is real. 

Desi Buffalo Ghee is creamier and richer in fat than cow ghee. It gives more energy, works very well in sweets and heavy cooking, and usually keeps longer because it has less moisture. Many households prefer bilona buffalo ghee for its strong taste and body. 

Pure buffalo ghee is usually pale cream to light yellow. Cow ghee, especially a2 desi cow ghee or a2 gir cow ghee, is more golden yellow. If a product labeled buffalo ghee looks very golden, it might be mixed with cow ghee. 

Do these easy checks:

1. Smell it. Pure buffalo ghee has a natural rich smell, not chemical.
   
2. Cool a spoonful in the fridge. Buffalo ghee firms up and becomes paler.
   
3. Look for small natural granules if it is labeled Desi Danedar Ghee.
   
4. Ask the seller for a lab report or test date.
