Buttermilk. The name conjures images of fluffy pancakes, moist cakes, and tangy marinades. But have you ever stopped to consider what exactly buttermilk is? And more importantly, is there a difference between the buttermilk you find in the dairy aisle and the “real” buttermilk of days gone by? The answer, as with many things in the culinary world, is a bit nuanced. This article delves into the fascinating differences between cultured buttermilk and the more historical “regular” buttermilk, exploring their origins, production methods, flavors, and uses in the kitchen.
Understanding the Historical Roots of “Regular” Buttermilk
To truly understand the difference between the two types of buttermilk, we need to travel back in time to the pre-industrial era of dairy farming. Before homogenization and widespread refrigeration, milk separation was a much more hands-on process.
The Cream Separation Process
The key to understanding “regular” buttermilk lies in how cream was traditionally separated from whole milk. Freshly milked milk was allowed to sit undisturbed, allowing the fat globules to rise to the top, forming a layer of cream. This cream was then skimmed off, leaving behind the milk with significantly reduced fat content. This remaining milk, quite naturally, was known as skim milk.
Churning Cream into Butter
The separated cream wasn’t simply consumed as is. It was destined for a higher purpose: butter. The cream was churned, a process that agitates the fat globules, causing them to clump together and eventually separate from the remaining liquid. This liquid, the byproduct of butter making, is what we traditionally know as “regular” buttermilk.
Characteristics of Traditional Buttermilk
This “regular” buttermilk was thin, slightly tangy, and naturally low in fat. Its tanginess came from the natural lactic acid bacteria present in the milk, which began to ferment the milk sugars (lactose) during the cream separation and churning process. The fat content was significantly lower than whole milk, as most of the fat had been removed with the cream. Think of it as a serendipitous byproduct of butter production, a naturally fermented and incredibly versatile ingredient.
The Advent of Cultured Buttermilk: A Modern Interpretation
As dairy farming evolved and technology advanced, the traditional method of making buttermilk became less common. Enter: cultured buttermilk, a product designed to mimic the flavor and properties of its historical counterpart.
The Culturing Process: Introducing Bacteria
Cultured buttermilk is made by adding specific strains of lactic acid bacteria to pasteurized skim or low-fat milk. These bacteria, such as Lactococcus lactis and Leuconostoc mesenteroides, consume the lactose in the milk and produce lactic acid as a byproduct. This lactic acid is what gives cultured buttermilk its characteristic tangy flavor and thick texture.
Control and Consistency
The key difference between cultured buttermilk and “regular” buttermilk lies in the controlled fermentation process. By adding specific bacterial cultures, manufacturers can ensure a consistent flavor and texture in their buttermilk. This is in stark contrast to the naturally occurring fermentation of “regular” buttermilk, which could vary depending on the environmental conditions and the bacteria present in the raw milk.
Texture and Flavor Profile
Cultured buttermilk is typically thicker than “regular” buttermilk, due to the increased lactic acid production and the presence of bacterial byproducts. It also has a more pronounced tangy flavor, often described as slightly sour. The controlled fermentation creates a predictable and consistent product, making it a reliable ingredient for baking and cooking.

What exactly is the difference between cultured buttermilk and regular buttermilk?
Cultured buttermilk is created through a controlled fermentation process. Specific strains of bacteria, often from the Lactococcus or Leuconostoc families, are added to pasteurized milk. These bacteria consume lactose, producing lactic acid as a byproduct. This process thickens the milk, gives it a characteristic tangy flavor, and extends its shelf life.
Regular buttermilk, also known as traditional buttermilk, is the liquid left over after churning butter from cream. While it still contains some residual fat and lactose, it’s significantly thinner and has a milder flavor than cultured buttermilk. Traditional buttermilk is becoming increasingly rare as butter production methods have evolved.
How does the taste of cultured buttermilk compare to regular buttermilk?
Cultured buttermilk boasts a distinctly tangy and slightly sour flavor profile. This is due to the lactic acid produced by the bacteria during fermentation. The tanginess adds complexity to dishes and is often preferred for baking and cooking where a pronounced buttermilk flavor is desired.
Regular buttermilk, on the other hand, has a much milder and subtler flavor. It retains some of the creamy notes from the original cream used to make butter, but lacks the intense tang of cultured buttermilk. This makes it suitable for applications where you want a hint of buttermilk flavor without overpowering the other ingredients.
Can I substitute cultured buttermilk for regular buttermilk in recipes?
In most recipes, yes, you can substitute cultured buttermilk for regular buttermilk, although the result may vary slightly. Cultured buttermilk will impart a more pronounced tang and can result in a slightly richer texture in baked goods. Adjust the amount of acidic ingredients, like lemon juice or vinegar, if necessary to balance the flavor.
However, be mindful that the texture difference might require minor adjustments. Cultured buttermilk is generally thicker than regular buttermilk, so you might need to slightly reduce the amount of liquid in the recipe or add a touch more flour to compensate. Always taste your batter or dough and adjust accordingly.
Is cultured buttermilk healthier than regular buttermilk?
Cultured buttermilk offers several potential health benefits due to the presence of probiotics. These beneficial bacteria can contribute to improved gut health, aiding digestion and boosting the immune system. The fermentation process also breaks down lactose, potentially making it easier to digest for those with mild lactose sensitivities.
While regular buttermilk retains some nutrients from the original cream, it lacks the probiotic benefits of cultured buttermilk. It still contains vitamins and minerals, such as calcium and potassium, but its health profile is less pronounced than that of its cultured counterpart. However, both types of buttermilk are relatively low in fat compared to whole milk.
How do I store cultured buttermilk and regular buttermilk to maximize their shelf life?
Both cultured and regular buttermilk should be stored in the refrigerator immediately after purchase or opening. Always ensure the container is tightly sealed to prevent contamination and preserve freshness. Leaving buttermilk at room temperature will accelerate spoilage.
Cultured buttermilk generally has a longer shelf life than regular buttermilk due to the presence of lactic acid, which inhibits the growth of spoilage bacteria. Check the expiration date on the container and discard if it has passed. Signs of spoilage include a sour smell, unusual color, or curdled texture.
What are some common culinary uses for cultured buttermilk?
Cultured buttermilk is a versatile ingredient used in a wide range of culinary applications. It’s a popular choice for marinades, as the lactic acid tenderizes meat, adds flavor, and helps retain moisture during cooking. It’s also commonly used in dressings and sauces for its tangy flavor and creamy texture.
In baking, cultured buttermilk adds a moistness and subtle tang that enhances the flavor and texture of cakes, biscuits, pancakes, and muffins. It also reacts with baking soda to create leavening, resulting in a lighter and fluffier final product. Its unique flavor profile elevates many sweet and savory dishes.
Can I make my own cultured buttermilk at home?
Yes, making your own cultured buttermilk at home is a straightforward process. You’ll need pasteurized milk (avoid ultra-pasteurized), a small amount of existing cultured buttermilk (as a starter), and a clean container. Simply combine the milk and buttermilk in the container, stir gently, and let it sit at room temperature for 12-24 hours until thickened.
Once thickened, refrigerate the homemade buttermilk to stop the fermentation process. You can then use it in your recipes. Be sure to reserve a small amount of your homemade buttermilk to use as a starter for your next batch. This ensures a continuous supply of fresh, homemade cultured buttermilk.
