Processing: Roasting vs. Shade-Growing
Both hojicha and matcha originate from the Camellia sinensis plant, but their processing methods create significant differences in their caffeine content, flavor, and color.
The Matcha Process: Shade and Stone-Grinding
Matcha production involves shading tea plants before harvest, increasing chlorophyll and L-theanine. The young leaves are steamed, de-veined, and stone-ground into a fine powder. Consuming the entire leaf results in a higher intake of caffeine and other compounds.
The Hojicha Process: High-Heat Roasting
Hojicha, a roasted green tea, typically uses older leaves, stems, and twigs, which naturally contain less caffeine. Roasting these parts at high heat gives hojicha its unique toasted flavor and reddish-brown color while breaking down or evaporating some caffeine, significantly lowering its content.
The Caffeine Breakdown
The primary reason for the caffeine difference lies in the processing. Matcha's shade-growing and whole-leaf consumption increase caffeine, while hojicha's use of older leaves and roasting process reduce it. This makes hojicha a suitable low-caffeine option for the evening.
Hojicha vs. Matcha: A Caffeine Comparison Table
Below is a comparison of typical caffeine content for an 8 oz (240ml) serving, illustrating the difference.
| Feature | Hojicha | Matcha | 
|---|---|---|
| Processing | Roasted at high heat | Shade-grown, stone-ground | 
| Plant Parts | Older leaves, stems, twigs | Young, high-grade leaves | 
| Flavor Profile | Toasty, nutty, smoky, mellow | Grassy, vegetal, umami, creamy | 
| Approximate Caffeine (8oz cup) | 7–20 mg (leaves) | |
| 20–30 mg (powder) | 60–80 mg (powder) | |
| Best For | Afternoon/Evening, Relaxation | Morning/Daytime, Focus | 
Beyond Caffeine: Flavor and Effects
Matcha offers a sustained energy boost from caffeine and L-theanine, promoting focused alertness. Hojicha's roasting reduces astringency, offering a smooth, mellow, and comforting flavor with a calming effect due to pyrazine and lower L-theanine.
Choosing the Right Tea for the Right Time
The choice between the two depends on your needs. Matcha is best for a morning energy boost and focus. Hojicha is ideal for a relaxing, low-caffeine evening drink. Both teas can complement each other, with matcha for mornings and hojicha for evenings.

Conclusion: Hojicha is Not More Caffeinated Than Matcha
In summary, hojicha is not more caffeinated than matcha. Matcha's higher caffeine content is due to using young, shade-grown leaves and consuming the whole leaf. Hojicha has less caffeine because it's made from older plant parts and is roasted at high heat. Matcha is for energy and focus, while hojicha is for relaxation and a low-caffeine option. Understanding these distinctions helps tea drinkers choose the right tea.
