Is Tempeh Vegan? Is It Vegetarian? Everything You Need to Know

If you’re vegan, vegetarian, or just trying to understand what’s in your food, the question is a fair one: tempeh is fermented with a mould — does that make it non-vegan? Does fermentation involve anything animal-derived? Let’s settle it definitively.

Is Tempeh Vegan?

Yes, tempeh is 100% vegan.

Traditional tempeh contains exactly two ingredients: whole soybeans (or other legumes) and Rhizopus oligosporus — a mould culture. No animal products, no dairy, no eggs, no honey, no animal-derived processing aids. Even the most strict interpretations of veganism have no issue with tempeh.

Is Tempeh Vegetarian?

Yes, completely. Tempeh contains no meat, no fish, no poultry, and no by-products of animal slaughter. It is suitable for all categories of vegetarianism including:

• Lacto-vegetarian ✅
• Ovo-vegetarian ✅
• Lacto-ovo vegetarian ✅
• Vegan ✅
• Plant-based ✅

What About the Mould? Is That Vegan?

The mould used in tempeh fermentation — Rhizopus oligosporus — is a fungus, not an animal. It belongs to the same biological kingdom as mushrooms. Most vegans are entirely comfortable consuming fungi, and there is no serious ethical argument within veganism against consuming mould-fermented foods.

The same applies to all fermented foods: wine (yeast), beer (yeast), sourdough bread (wild yeast and bacteria), miso (Aspergillus mould), soy sauce (Aspergillus mould). None of these are considered non-vegan because of their microbial cultures.

Is Tempeh Gluten-Free?

Traditional soy tempeh is gluten-free — soybeans contain no gluten. Chickpea tempeh is also gluten-free. However, flavoured or marinated tempeh products may contain soy sauce (which typically contains wheat) or other gluten-containing ingredients. Always check the ingredient label for flavoured varieties.

Tempewala’s plain fresh tempeh — soy and chickpea — is gluten-free.

Is Tempeh Halal?

Plain fermented tempeh made from soybeans or chickpeas is halal — there are no pork products or alcohol derived from the fermentation process. Rhizopus fermentation does not produce ethanol. Many Indonesian tempeh producers supply to Muslim-majority communities.

Is Tempeh Jain-Friendly?

This is more nuanced. Strict Jain dietary practice avoids root vegetables and certain legumes eaten during particular periods. The fermentation process and microbial activity in tempeh may also be a consideration for some Jain practitioners. We recommend consulting with your religious community regarding fermented foods if this applies to you.
