How Much Rosin from 28g (Complete Beginner’s Guide)

If you’re new to rosin pressing, one of the first questions that comes to mind is, How much rosin from 28g of flower can I get? The answer depends on many things like quality, strain, and pressing method. Rosin pressing is becoming more popular because it’s clean, solventless, and easy to do at home. If you’re pressing for fun or for personal use, knowing your yield helps you plan better and save time and material.

In this guide, we’ll explain everything in simple words — from what rosin is, how it’s made, and how much yield you can expect from 28 grams of cannabis flower. Let’s get started.

What Is Rosin?

Rosin is a type of cannabis concentrate made without using any chemicals or solvents. It’s created by pressing cannabis flower, kief, or hash between two heated plates. The pressure and heat squeeze out the resin, which is full of cannabinoids and terpenes — the stuff that gives cannabis its flavor, aroma, and effects.

Unlike other concentrates that use butane or alcohol, rosin is made using only heat and pressure. That’s why it’s called a solventless extract. Many people prefer rosin because it’s pure, safe, and easy to make at home. You don’t need fancy lab equipment — just a press, parchment paper, and patience.

How Is Rosin Made?

Making rosin is simple once you understand the process. All you need is a rosin press, some parchment paper, and micron filter bags (optional).

Here’s how it works:
You place your cannabis inside a filter bag, wrap it in parchment paper, and then press it under heat and pressure. The heat melts the trichomes, and the pressure pushes the resin out onto the paper. After cooling, the rosin hardens into a sticky, golden extract that’s ready to use.

Temperature and pressure play a big role. Pressing too hot can burn terpenes and reduce flavor. Pressing too cold might lower yield. So, finding the right balance is important.

Understanding Rosin Yield

Before we calculate how much rosin you can get from 28 grams, let’s understand what yield means. In simple terms, yield is the amount of rosin you collect compared to the amount of cannabis you pressed. It’s usually shown as a percentage.

For example:
If you press 10 grams of flower and get 2 grams of rosin, your yield is 20%.

The yield depends on:

The quality of your starting material.
The strain or genetics.
The temperature and pressure used.
The freshness and moisture of the flower.

So, there’s no fixed answer for everyone — but we can find a realistic average.

How Much Rosin from 28g of Flower?

Now let’s answer the big question — how much rosin can you expect from 28 grams (1 ounce) of flower?

On average, you can expect between 15% and 25% yield from high-quality cannabis flower. That means from 28 grams, you can get anywhere from 4 to 7 grams of rosin.

Here’s a simple breakdown:

Low-quality flower (10% yield): 2.8 grams rosin
Average-quality flower (15–20% yield): 4–5.6 grams rosin
Top-quality flower (25% yield or more): 7 grams rosin

Example:
If your strain gives a 20% yield, then 28g × 20% = 5.6 grams of rosin.

Remember, every strain behaves differently. Some are naturally more resinous, while others may give less rosin even if they look good. The only way to know for sure is by pressing and testing.

Factors That Affect Rosin Yield

Many things affect how much rosin you get from 28g of flower. Let’s look at the main ones in simple terms:

1. Quality of the Flower

The better your cannabis, the higher the yield. Fresh, sticky, trichome-rich buds produce more rosin. Dry or old flower gives less. Always choose fresh material for pressing.

2. Strain Genetics

Some strains produce more resin than others. For example, Gorilla Glue, Wedding Cake, and Gelato strains are known for high resin content. Indica-dominant strains often yield better than sativa strains.

3. Moisture Level

Cannabis should have about 60–65% relative humidity before pressing. If it’s too dry, it absorbs rosin back into the plant material. If it’s too wet, steam and bubbles form, lowering yield.

4. Temperature and Pressure

Ideal temperature ranges between 180°F and 220°F. Lower heat gives better flavor but less yield. Higher heat increases yield but may reduce quality. Find a balance depending on your goal.

5. Rosin Bag and Micron Size

Use a 90–120 micron bag for flower. Too tight a bag can restrict flow, while too loose may let plant material mix into your rosin. Using the right bag helps you get a clean, higher yield.

Flower Rosin vs. Hash Rosin: Which Is Better?

When pressing 28g, you can start with flower or hash/kief. The results are very different.

Flower Rosin Yield: 15–25%
Hash Rosin Yield: 60–75%

That means 28g of hash can give up to 16–20g of rosin, while the same amount of flower gives around 4–7g.

Hash rosin is more potent because it starts with concentrated material. But pressing hash requires more skill and a cleaner setup. Beginners usually start with flower rosin because it’s easier and more forgiving.

How to Increase Rosin Yield from 28g

If you’re getting low yields, don’t worry. Here are simple tips to increase rosin output:

Use fresh, sticky buds. Old, dry weed won’t press well.
Keep humidity around 60%. You can use a humidity pack before pressing.
Find the right heat. Start at 200°F and adjust if needed.
Press slowly. Don’t apply full pressure too fast; increase it gradually.
Use quality filter bags. Prevent plant matter from leaking into your rosin.
Collect properly. Scrape rosin gently and store it in a cool place.

Even small changes can increase your yield by 5–10%. Try experimenting with one factor at a time.

Quality vs. Quantity: What Matters More

Many beginners focus on yield, but quality is equally important. You might get 7g of rosin from 28g of flower, but if it’s dark, burnt, or has a bad taste, it’s not worth it.

High-quality rosin should be:

Light golden or amber in color.
Sticky but not runny.
Smooth aroma with no burnt smell.

Sometimes pressing at a slightly lower temperature gives less yield but much better flavor and potency. Always aim for balance — good yield with high quality.

Example Rosin Yield Chart

Here’s a simple reference table for 28g of flower:

Flower Quality	Expected Yield %	Estimated Rosin (g)
Low Quality	10–15%	2.8–4.2g
Medium Quality	15–20%	4–5.6g
High Quality	20–25%+	5.6–7g

This is just a general idea. Actual results depend on your strain and press settings.

Common Mistakes Beginners Make

When learning rosin pressing, small errors can make a big difference. Here are a few common mistakes and how to fix them:

Pressing too hot: Burns terpenes, darkens rosin. → Keep under 220°F.
Using dry weed: Low yield and sticky residue. → Rehydrate with humidity packs.
Too much pressure too soon: Ruins bag or leaks. → Increase slowly.
Wrong micron bag: Use 90–120 for flower.
Skipping pre-press: Compact material before pressing for better contact.

Avoiding these mistakes can improve both your rosin quality and yield.

Understanding Growth and Extraction: Life Cycle of a Radish with Labels

Just like the life cycle of a radish with labels shows each step of growth — from seed to root to harvest — rosin production also follows a clear, natural process. The radish starts as a seed, matures, and then gets harvested at the perfect time for the best flavor and quality. Similarly, cannabis must also go through proper growth, drying, and curing stages before pressing. Both processes teach us that timing, care, and patience lead to better results and higher quality yields.

How to Store Rosin the Right Way

Storage matters more than most people think. Rosin can lose flavor and potency over time if not stored correctly.

Follow these tips:

Use airtight glass jars.
Keep in a cool, dark place away from sunlight.
For long-term storage, refrigerate in silicone or parchment.

Stored properly, rosin can last for several months without losing quality.

Is Pressing Rosin Worth It?

Many wonder if pressing rosin from 28g is worth the time and effort. The answer depends on your goals. If you enjoy DIY projects and want a clean, chemical-free extract, it’s absolutely worth it.

Financially, pressing your own rosin is often cheaper than buying ready-made concentrates. A one-time investment in a press can save you money long-term. Plus, you control the quality, strain, and flavor yourself.

Final Thoughts

So, how much rosin from 28g can you get? The honest answer is between 4 to 7 grams, depending on your strain, method, and skill. A yield of 20% is a good benchmark for most home pressers.

Rosin pressing is all about experimentation. The more you practice, the better your results will be. Focus on good material, correct temperature, and patience. With time, you’ll find your sweet spot and get golden, flavorful rosin every time.

Remember: quality matters more than numbers. Happy pressing!
