True Herb

True Herb makes the H-Brewer, a countertop appliance that decarboxylates plant material and then infuses it into oil or butter in the same enclosed vessel. It holds 300 to 700 ml per batch, which suits home kitchens making small to medium batches.

The activation mode heats from 230°F to 250°F (110°C to 122°C), and the infusion mode runs from 70°F to 212°F (20°C to 100°C). A single button selects the mode, heat and time, and heating sensors hold the set temperature through the cycle. The vessel and stainless strainer are dishwasher safe.

True Herb: Complete Guide

Is the True Herb H-Brewer the Right Infuser for My Kitchen?

Making an infused oil or butter takes two heating steps. First the plant material is decarboxylated, or activated, with dry heat. Then it steeps in warm oil or butter long enough to transfer into it. Done in an oven and a saucepan, both steps depend on guessing the real temperature. The True Herb H-Brewer runs both in one enclosed vessel, with sensors holding each temperature, so the result depends far less on watching the stove.

The trade-off is batch size. At 300 to 700 ml per run, the H-Brewer is sized for home batches rather than production volumes, and its 8 x 10 x 8 inch footprint fits on a counter beside other small appliances.

What Temperatures Does Each Mode Use?

Mode Temperature Range What It Does
Activate 230-250°F (110-122°C) Decarboxylates dry plant material before infusing
Infuse 70-212°F (20-100°C) Steeps activated material in oil or butter

The two ranges do not overlap: activation runs hotter, while infusion stays at or below 212°F, the boiling point of water. Time settings vary by plant material and by the oil or butter used, and the one-button interface sets both heat and time for each step.

What Should I Look for in a Decarboxylator and Infuser?

  • Both steps in one vessel: The H-Brewer activates and infuses without moving material between an oven tray and a pan.
  • Temperature control: Heating sensors maintain the set temperature for the whole cycle, and one button selects mode, heat and time.
  • Cleanup: The enclosed vessel and stainless steel strainer are dishwasher safe and have heat-resistant handles for lifting out a hot batch.
  • Footprint: The unit measures 8 x 10 x 8 inches, weighs 9.9 lb boxed and carries CE certification.

Cooks who want a larger batch or a different brand can compare other butter and oil infusion machines, and anyone moving on to concentrates can start with extraction and processing equipment.

Frequently Asked Questions

How large a batch does the H-Brewer make?
The H-Brewer holds 300 to 700 ml per batch, which covers small to medium home batches of infused oil or butter. Larger volumes mean running several cycles back to back or choosing a bigger machine.
Can one machine decarboxylate and infuse?
Yes. The H-Brewer is a 2-in-1 appliance. The activation mode heats plant material at 230°F to 250°F, then the infusion mode steeps it in the chosen oil or butter at 70°F to 212°F, all in the same enclosed vessel.
How long does a decarboxylation and infusion cycle take?
True Herb does not publish one fixed cycle time, because it varies with the plant material and the oil or butter used. The one-button interface sets the time for each mode, and a user manual ships with the unit to guide those settings.
Is the H-Brewer easy to clean?
The enclosed infusion vessel and the stainless steel strainer both go in the dishwasher. Each has a heat-resistant handle, so the vessel and strainer can be lifted out safely at the end of a cycle and the oil strained off.
What comes in the box?
The package includes the H-Brewer main unit, the enclosed infusion vessel with a heat-resistant handle, a stainless steel strainer and a user manual. The boxed unit weighs 9.9 lb and ships in an 11 x 14.2 x 13.4 inch carton.
