How To Make Hemp Tea With Stems: A Complete Guide To Extraction And Brewing

Brewing hemp tea with stems is an efficient, sustainable method to extract residual cannabinoids, terpenes, and flavonoids from leftover plant material. Because compounds like cannabidiol (CBD) are lipophilic, achieving high bioavailability requires precise decarboxylation and the inclusion of a dietary fat source during the simmering process.

Essential Preparation and Setup Requirements

Transforming raw industrial or medicinal hemp stems into a palatable, therapeutically viable herbal infusion requires meticulous attention to solvent chemistry and thermal activation. Stems typically contain lower concentrations of phytocannabinoids than trichome-dense floral material, meaning extraction parameters must be optimized to capture maximum value. Success depends entirely on controlling thermal energy, utilizing the correct solvent matrix, and adhering to precise extraction durations.

• Essential Equipment and Materials:

  
  
  
  • 5 to 10 grams of dried, cured hemp stems (free of mold or rot)
  • Heavy-duty stainless steel saucepan with a tight-fitting lid
  • Fine-mesh stainless steel strainer and unbleached paper coffee filter
  • 1 tablespoon of high-fat binder (whole milk, heavy cream, coconut oil, or butter)
  • 3 to 4 cups of filtered water
  • Food-grade digital kitchen scale and an instant-read digital cooking thermometer

• Prerequisite Standards and Knowledge:

  
  
  
  • Stems must undergo thermal decarboxylation if the goal is to convert acidic cannabinoids (like CBDA) into their neutral, active bioforms (like CBD).
  • Raw plant matter contains chlorophyll, waxes, and plant lipids that contribute a bitter, grassy flavor profile; straining and fat-binding agents mitigate this harshness.
  • Estimated operational duration: 45 to 60 minutes total (including decarb and simmer phases).
  • Estimated cost: Negligible, utilizing repurposed waste plant material.

Step-by-Step Hemp Stem Extraction Workflow

Step 1: Sorting, Cleaning, and Milling the Stems

Begin by inspecting your raw hemp stems for any signs of powdery mildew, moisture, or foreign debris. Separate the woody, thick main stalks from the smaller, resin-dusted fan and sugar leaf stems, as the thinner stems yield significantly higher concentrations of active phytocannabinoids. Using a clean pair of kitchen shears or a clean herb grinder, chop the stems down to uniform lengths of approximately one-quarter to one-half inch. This increases the surface area exposed to the water and fat solvents, ensuring a more thorough extraction of target compounds.

Pro-Tip: Store your collected stems in a paper bag in a cool, dark, and dry location until you have accumulated enough mass (at least 5 to 10 grams) to warrant a brewing batch.

Step 2: Thermal Decarboxylation of Plant Material

If your stems are raw and have not been exposed to prior heat, thermal activation is a critical prerequisite to unlock the physiological potential of cannabinoids. Preheat your kitchen oven to 240 degrees Fahrenheit (115 degrees Celsius). Spread your chopped hemp stems evenly across a baking sheet lined with unbleached parchment paper. Place the baking sheet on the middle oven rack and bake for exactly 35 to 45 minutes. Monitor the oven closely with an independent oven thermometer to prevent scorching, which degrades delicate terpenes and burns off valuable cannabinoids.

Warning: Exceeding 300 degrees Fahrenheit during decarboxylation will rapidly vaporize and destroy essential terpenes and degrade target cannabinoids into CBN and other unwanted degradation byproducts.

Step 3: Simmering and Phytocannabinoid Infusion

Transfer your decarboxylated hemp stems into a stainless steel saucepan and add 3 to 4 cups of filtered water. Turn the heat source to medium and bring the mixture to a gentle, rolling simmer. Once simmering, immediately reduce the heat to low. Add your chosen dietary fat source—such as one tablespoon of whole milk, butter, or coconut oil—to the pot. Because cannabinoids are hydrophobic, this lipid binding agent is mandatory for the compounds to cross intestinal membranes effectively during digestion. Cover the saucepan with its lid to prevent the volatile aromatic terpenes from escaping via steam. Maintain a low simmer for 30 to 45 minutes, stirring occasionally and adding small amounts of hot water if evaporation reduces the volume too drastically.

Step 4: Straining and Flavor Balancing

Remove the saucepan from the heat source and allow the liquid to cool to a safe handling temperature for approximately 5 minutes. Set your fine-mesh stainless steel strainer over a heat-resistant glass pitcher or directly into your teacups, lining the strainer with an unbleached paper coffee filter to catch microscopic plant particulates and bitter waxes. Carefully pour the hot hemp tea through the filtration apparatus, pressing gently on the spent stems with the back of a spoon to extract all remaining liquid. Taste the pure infusion; if the earthy, woody flavor profile is too robust, balance the palate by stirring in raw honey, organic agave syrup, a squeeze of fresh lemon juice, or a secondary herbal tea bag such as chamomile or peppermint.

Troubleshooting Common Brewing Failures

• Root Cause: The resulting tea produces virtually no physiological effects or therapeutic relaxation.

  
  
  
  • Actionable Fix: You likely skipped the decarboxylation step, leaving the cannabinoids locked in their acidic precursor states (CBDA), or you omitted the dietary fat source necessary for intestinal absorption. Ensure you bake the stems at 240 degrees Fahrenheit and always include a lipid like butter or whole milk in the simmering pot.

• Root Cause: The tea tastes overwhelmingly bitter, acrid, or unpleasantly grassy.

  
  
  
  • Actionable Fix: The stems were either boiled too aggressively instead of gently simmered, or the plant material was over-roasted during the decarb phase. Reduce your burner heat to the lowest setting, keep the lid on to trap steam, and sweeten the final brew with honey or citrus.

• Root Cause: A thick, waxy, or unappealing residue floats on the surface of the tea.

  
  
  
  • Actionable Fix: The plant waxes and lipids separated due to improper straining or using an unrefined fat source. Improve your filtration technique by passing the hot liquid through both a fine-mesh wire sieve and a paper coffee filter consecutively.

Frequently Asked Questions

Will making hemp tea with stems get me high?

No, industrial hemp stems derived from legal Cannabis sativa plants contain strictly regulated delta-9 tetrahydrocannabinol (THC) concentrations below 0.3 percent. This negligible amount of THC, combined with the presence of balancing cannabidiol (CBD), is entirely non-psychoactive and will not produce an intoxicating high.

How long can I store leftover hemp stems before brewing?

Properly dried and cured hemp stems can be stored for up to six months without significant cannabinoid degradation. Keep them in an airtight glass mason jar stored in a cool, dark, and dry environment to protect the plant material from ultraviolet light, humidity, and oxygen exposure.

Can I reuse hemp stems for a second batch of tea?

Reusing hemp stems is generally inefficient because the primary extraction cycle strips upwards of 85 to 90 percent of the available water-soluble and lipid-soluble compounds during the initial 40-minute simmer. Discard the spent plant material in your compost bin and use fresh stems for your next batch.

Does the thickness of the hemp stems affect potency?

Yes, thicker main stalks are primarily composed of structural cellulose and lignin, containing very few trichomes or glandular structures. Conversely, the smaller fan-leaf stems and floral-adjacent stems feature higher concentrations of resin glands, making them significantly more potent for tea brewing.

Can I mix hemp stems with regular black or green tea?

Absolutely. Combining your extracted hemp stem infusion with traditional black, green, or herbal teas is an excellent way to mask the earthy, botanical flavor of the plant. Brew your standard tea separately and blend it with your strained hemp infusion, or add the tea leaves directly into the simmering pot during the final five minutes of extraction.
