Creating cannabutter, or cannabis-infused butter, is a foundational skill for any home cannabis enthusiast looking to explore the world of edibles. From brownies and cookies to savory sauces and spreads, cannabutter opens the door to a diverse culinary landscape. But understanding the potency of your cannabutter is crucial for a safe and enjoyable experience. One of the most common questions arises: how much butter is actually in an ounce (oz) of cannabutter, and how does that impact the overall potency? This comprehensive guide will delve into the intricacies of cannabutter preparation, potency calculations, and factors influencing the final product.
Understanding Cannabutter Basics
Before diving into measurements, let’s establish a solid understanding of what cannabutter is and why it’s important to get the ratio right. Cannabutter is essentially regular butter that has been infused with the cannabinoids found in cannabis, primarily THC (tetrahydrocannabinol) and CBD (cannabidiol). The infusion process involves decarboxylation, which activates the cannabinoids, followed by simmering the cannabis in butter, allowing the cannabinoids to bind to the fat molecules.
Why is the butter-to-cannabis ratio so important? It directly influences the potency of your cannabutter. Too little cannabis, and you’ll have weak cannabutter. Too much, and you risk creating a product that is overwhelmingly potent and potentially uncomfortable. Achieving the right balance is key to consistent and predictable results. This balance becomes particularly important when you’re thinking about the yield of your cannabutter.
Decarboxylation: The Key to Activation
Decarboxylation is a crucial step in preparing cannabis for edible consumption. Raw cannabis contains THCA and CBDA, which are non-psychoactive precursors to THC and CBD. Decarboxylation involves heating the cannabis at a specific temperature for a specific duration to convert THCA into THC and CBDA into CBD.
The decarboxylation process can affect the final amount of cannabutter you yield. Proper decarboxylation ensures that the cannabinoids are fully activated, which directly impacts the potency of your final product. A good rule of thumb is to decarboxylate your cannabis before infusing it with the butter to ensure maximum potency.
Decarboxylation Methods
There are several methods for decarboxylating cannabis, each with its own set of advantages and disadvantages.
- Oven Method: This is the most common method. Preheat your oven to around 220-240°F (105-115°C) and spread the ground cannabis evenly on a baking sheet lined with parchment paper. Bake for 30-45 minutes, stirring occasionally to ensure even heating.
- Sous Vide Method: This method involves sealing the cannabis in a vacuum-sealed bag and immersing it in a water bath at a controlled temperature (around 203°F or 95°C) for 90 minutes.
- Dedicated Decarboxylators: These are specialized devices designed specifically for decarboxylating cannabis. They offer precise temperature control and consistent results.
Regardless of the method you choose, it’s crucial to monitor the temperature and duration carefully to avoid burning off the cannabinoids. Over-decarboxylation can degrade the cannabinoids and reduce the potency of your cannabutter.
The Cannabutter Infusion Process
Once your cannabis is decarboxylated, it’s time to infuse it with butter. The infusion process allows the cannabinoids to bind to the fat molecules in the butter, creating cannabutter. There are several methods for infusing cannabis into butter.
Stovetop Method
This is a traditional method that involves simmering the decarboxylated cannabis in melted butter over low heat.
- Melt the butter in a saucepan over low heat.
- Add the decarboxylated cannabis to the melted butter.
- Simmer the mixture over low heat for 2-3 hours, stirring occasionally.
- Strain the mixture through a cheesecloth-lined strainer to remove the plant material.
- Allow the cannabutter to cool and solidify.
Slow Cooker Method
This method provides a more consistent and hands-off approach.
- Combine the decarboxylated cannabis and melted butter in a slow cooker.
- Cook on low heat for 4-6 hours, stirring occasionally.
- Strain the mixture through a cheesecloth-lined strainer to remove the plant material.
- Allow the cannabutter to cool and solidify.
Infusion Machines
Several commercially available infusion machines, such as the MagicalButter Machine and the LEVO, are designed specifically for making cannabutter and other cannabis infusions. These machines offer precise temperature control and automated stirring, making the process easier and more consistent.
Factors Affecting Cannabutter Yield
The amount of cannabutter you yield from an ounce of cannabis can vary depending on several factors, including:
- Starting Material: The quality and potency of your cannabis will directly impact the potency of your cannabutter.
- Infusion Method: Different infusion methods may result in slightly different yields.
- Straining Technique: How thoroughly you strain the mixture will affect the final volume of cannabutter.
- Butter Quality: The type of butter you use can also affect the yield.
Calculating Cannabutter Potency
Calculating the potency of your cannabutter is essential for accurate dosing and a safe edible experience. The calculation involves determining the approximate THC content in your starting material and then estimating how much of that THC is transferred to the butter. While precise measurements require laboratory testing, you can get a reasonable estimate using the following steps:
- Determine the THC content of your cannabis: This information is typically provided by the dispensary or grower. If you don’t know the exact THC percentage, you can estimate it based on the strain and quality of the cannabis. A good starting point for average cannabis is around 15-20% THC.
- Convert the THC percentage to milligrams: An ounce of cannabis contains 28 grams, or 28,000 milligrams. If your cannabis is 20% THC, then one ounce contains 5,600 mg of THC (28,000 mg x 0.20).
- Estimate the THC transfer rate: The infusion process isn’t 100% efficient. Some THC will be lost during decarboxylation and infusion. A reasonable estimate for THC transfer is between 70-90%. Let’s use 80% for this example.
- Calculate the total THC in your cannabutter: Multiply the total THC in your cannabis by the estimated transfer rate. In our example, 5,600 mg THC x 0.80 = 4,480 mg THC in the total batch of cannabutter.
- Determine the volume of your cannabutter: Measure the volume of your finished cannabutter in ounces. If you started with one cup (8 ounces) of butter, you might end up with slightly less due to absorption by the plant material. Let’s assume you have 7 ounces of cannabutter.
- Calculate the THC per ounce of cannabutter: Divide the total THC in the cannabutter by the number of ounces. In our example, 4,480 mg THC / 7 ounces = 640 mg THC per ounce.
Example Potency Calculation
Let’s break down an example calculation:
- Cannabis Used: 1 ounce
- THC Content: 20%
- Estimated THC Transfer Rate: 80%
- Finished Cannabutter Volume: 7 ounces
Calculations:
- Total THC in Cannabis: 28,000 mg x 0.20 = 5,600 mg
- THC Transferred to Butter: 5,600 mg x 0.80 = 4,480 mg
- THC per Ounce of Cannabutter: 4,480 mg / 7 ounces = 640 mg/oz
Therefore, in this example, each ounce of cannabutter contains approximately 640 mg of THC.
Variables Affecting Potency
Several factors can affect the final potency of your cannabutter:
- Accuracy of THC Content: The THC percentage provided by the dispensary may not be perfectly accurate.
- Decarboxylation Efficiency: Incomplete decarboxylation will result in lower potency.
- Infusion Efficiency: The infusion process may not extract all of the THC from the cannabis.
- Straining Losses: Some THC may be lost during the straining process.
- Cannabis Strain: Different cannabis strains have different levels of THC.
How Much Butter is Actually in an Ounce of Cannabutter?
The question of how much butter is actually in an ounce of cannabutter might seem straightforward, but it’s important to clarify. An ounce of cannabutter, like an ounce of regular butter, is a unit of weight. One fluid ounce is a unit of volume.
An ounce of cannabutter will weigh approximately 28.35 grams. This measurement applies regardless of the infusion process. What changes is the concentration of THC within that ounce of butter. The amount of actual “butter” remains the same in terms of weight. So, one ounce of cannabutter always contains 28.35 grams of butter and infused cannabis oils. However, knowing the potency of that ounce (e.g., how many milligrams of THC are present) is the critical factor for dosing.
The Relationship Between Butter Volume and Weight
While we typically measure liquids in fluid ounces, butter is often measured by weight. It’s helpful to understand the relationship between butter volume and weight:
- 1 cup of butter (8 ounces by volume) weighs approximately 226 grams (8 ounces by weight).
- 1 tablespoon of butter weighs approximately 14 grams.
Keep in mind that these are approximate values, and the actual weight may vary slightly depending on the density of the butter. When making cannabutter, it’s best to use weight measurements for accuracy.
Dosage and Consumption
Once you’ve calculated the potency of your cannabutter, it’s crucial to start with a low dose, especially if you’re new to edibles. Edibles can have a much stronger and longer-lasting effect compared to smoking or vaping. A typical starting dose for edibles is 5-10 mg of THC.
To determine the appropriate dose, divide the THC content per ounce by the desired dose:
- If your cannabutter contains 640 mg of THC per ounce, and you want a 5 mg dose, you would need approximately 0.0078 ounces (5 mg / 640 mg/oz). This equates to a very small amount of butter, approximately 0.22 grams.
It’s always best to start with a low dose and wait at least 1-2 hours to feel the effects before consuming more. Everyone reacts differently to edibles, so it’s important to be patient and responsible.
Tips for Safe Edible Consumption
- Start low and go slow: Begin with a low dose and wait at least 1-2 hours to feel the effects.
- Read labels carefully: If you’re purchasing edibles from a dispensary, carefully read the labels to understand the THC content.
- Store edibles safely: Keep edibles out of reach of children and pets.
- Avoid mixing with alcohol or other drugs: Mixing edibles with alcohol or other drugs can intensify the effects and increase the risk of adverse reactions.
- Be patient: Edibles can take longer to kick in compared to other methods of consumption.
Troubleshooting Common Cannabutter Issues
Even with careful planning and execution, you may encounter issues while making cannabutter. Here are some common problems and how to address them:
- Weak Cannabutter: If your cannabutter is weak, it could be due to several factors, including insufficient decarboxylation, low-quality cannabis, or inefficient infusion.
- Cannabutter is Too Strong: If your cannabutter is too strong, it could be due to using high-potency cannabis or an inaccurate potency calculation.
- Grassy Taste: A grassy taste in your cannabutter can be minimized by using high-quality butter, thoroughly straining the mixture, and water-curing the cannabis before infusion.
- Cannabutter is Separating: Cannabutter may separate during cooling. This is normal and can be easily remedied by gently reheating and mixing the butter.
Advanced Techniques for Enhancing Cannabutter Quality
For those looking to take their cannabutter to the next level, consider these advanced techniques:
- Water Curing: Water curing involves soaking the cannabis in water for several days to remove chlorophyll and other undesirable compounds, resulting in a smoother and less grassy-tasting cannabutter.
- Using Clarified Butter (Ghee): Clarified butter, or ghee, has a higher fat content and lower moisture content compared to regular butter, which can improve the quality and shelf life of your cannabutter.
- Adding Lecithin: Lecithin is an emulsifier that can help bind the cannabinoids to the butter more effectively, resulting in a more potent and consistent product.
- Infusing with Other Fats: Besides butter, you can infuse cannabis with other fats, such as coconut oil, olive oil, and MCT oil, depending on your dietary preferences and culinary needs.

Making cannabutter is a rewarding skill that allows you to explore the diverse world of cannabis edibles. Understanding the potency of your cannabutter and practicing safe dosing are crucial for a positive experience. By following the guidelines and techniques outlined in this article, you can confidently create high-quality cannabutter that meets your specific needs and preferences. Remember to prioritize accuracy, patience, and responsible consumption, and enjoy the culinary possibilities that cannabutter offers.
How does the amount of butter used affect the potency of cannabutter?
The amount of butter used directly impacts the concentration of cannabinoids, like THC and CBD, in the final product. Using more butter with the same amount of cannabis results in a weaker cannabutter because the cannabinoids are dispersed throughout a larger volume. Conversely, using less butter results in a stronger, more concentrated cannabutter.
It’s crucial to find a balance that aligns with your desired potency. Consider your experience level with edibles and the potency of the cannabis you’re using. Experimentation, starting with smaller batches, is recommended to determine the optimal butter-to-cannabis ratio for your specific needs and preferences.
What is the typical ratio of cannabis to butter used in cannabutter recipes?
While there isn’t a single “typical” ratio, a commonly recommended starting point is around 1 ounce (28 grams) of cannabis flower to 1 cup (2 sticks or 8 ounces) of butter. This ratio allows for a decent level of potency without being overwhelmingly strong for beginners. However, this is merely a starting point and needs adjustment based on the cannabis strain’s THC/CBD content.
Experienced users often adjust the ratio to as low as 1/2 ounce (14 grams) to 1 cup of butter for a more potent product, while novices might prefer 1.5 ounces (42 grams) of cannabis to 1 cup of butter for a milder effect. The key is to understand the strength of your cannabis and adjust the ratio accordingly.
How does the quality of cannabis impact the potency of cannabutter?
The quality of cannabis is a major determining factor in the final potency of your cannabutter. High-quality cannabis, meaning cannabis with a higher percentage of THC or CBD, will naturally produce more potent cannabutter compared to lower-quality cannabis with lower cannabinoid levels. This is because there are simply more cannabinoids available to be infused into the butter.
Factors like the cannabis strain, how well it was grown, and how carefully it was stored all contribute to its quality and cannabinoid content. Always choose the best quality cannabis you can access and ideally have access to lab results that quantify the THC and CBD percentage. This will allow you to better predict and control the potency of your cannabutter.
What steps can I take to ensure accurate dosing of my cannabutter?
Accurate dosing of cannabutter is crucial for a safe and enjoyable experience. The best way to ensure accuracy is to know the THC content of the cannabis used. If possible, obtain lab-tested cannabis with a known THC percentage. This will allow you to calculate the approximate milligrams of THC per serving of cannabutter.
After infusion, begin with very small doses (around 5-10mg of THC) to assess your tolerance. Keep detailed notes of your infusions, including the exact amount of cannabis used, the amount of butter, and the estimated THC content per serving. Remember that edibles can take up to two hours to fully take effect, so be patient and avoid taking more until you’ve felt the effects of the initial dose.
Does the decarboxylation process affect the potency of cannabutter?
Decarboxylation is an essential step in the cannabutter-making process and has a significant impact on the potency of the final product. Decarboxylation involves heating cannabis to a specific temperature for a certain duration to convert THCA (tetrahydrocannabinolic acid) and CBDA (cannabidiolic acid) into their active forms, THC and CBD, respectively. Without decarboxylation, the cannabinoids will remain in their inactive acid forms, resulting in a far less potent or even ineffective cannabutter.
Proper decarboxylation ensures that the maximum amount of THC and CBD are available to infuse into the butter. This step unlocks the psychoactive and therapeutic effects of the cannabis. A typical decarboxylation process involves baking the ground cannabis at around 220-240°F (104-115°C) for 30-60 minutes, but precise times and temperatures can vary.
How can I store cannabutter to maintain its potency?
Proper storage is crucial for preserving the potency and quality of cannabutter. Like regular butter, cannabutter is susceptible to degradation from light, heat, and air exposure. These elements can degrade the cannabinoids, reducing the potency of the butter over time.
The best way to store cannabutter is in an airtight container in the refrigerator. This will help to slow down the degradation process and maintain its potency for several weeks. For longer-term storage (several months), consider freezing the cannabutter. When freezing, ensure it is well-wrapped to prevent freezer burn and maintain its quality.
Can the cooking method used to make cannabutter affect its potency?
Yes, the cooking method significantly influences the final potency of your cannabutter. Overheating cannabutter can degrade the THC and other cannabinoids, reducing its potency. High temperatures cause the volatile compounds to evaporate, diminishing the desired effects.
Slow cooking methods, like using a slow cooker or double boiler, are recommended. These methods provide gentle heat over a longer period, allowing for efficient cannabinoid extraction without burning or degrading the butter. Maintaining a consistent, low temperature throughout the cooking process is essential for maximizing potency.
