The Complete Handbook of Tempeh

I was expecting another recipe book with a few tips sprinkled in, but this actually explains the fermentation parameters in measurable terms. The acidification and humidity targets alone were worth the price. I docked one star because the equipment chapter leans toward commercial-scale setups and there is not much for someone doing 5-pound home batches, but for a professional reference it is well done.

This is the book I have been looking for for years. I have been buying tempeh wholesale for my restaurant and I never had a clear way to evaluate suppliers — pH, moisture content, binding quality? I had no vocabulary for it. Now I do. Chapter 3 alone changed how I order, and the troubleshooting table in Chapter 5 solved a recurring spoilage issue we had with a specific vendor. Absolutely worth it.

Solid reference overall, and the chapter on specifications is genuinely useful if you are sourcing or producing at scale. My only complaint is that the future trends chapter feels a bit conservative — it lists directions that most people in the industry already know. For someone new to the category, it would be useful, but I was hoping for more forward-looking analysis.

Finally, a tempeh book that treats the subject seriously. The author clearly knows fermentation science but writes in plain language. The troubleshooting chapter is the most practical thing I have read on tempeh defects — I diagnosed a bacterial contamination issue in my facility within an hour of reading it. The pH targets and temperature ranges are exactly what I needed. My copy is full of sticky notes.

As someone who has made tempeh for years as a serious hobbyist, I appreciated how this book confirms what works and explains why. The section on acidification finally helped me understand why my batches sometimes smelled sour even when the texture looked fine. It is not a recipe book, which is exactly what I wanted. If you want to understand the process rather than just follow steps, get this.

I run a small wholesale tempeh operation and this book has become my on-the-shelf reference. The specifications chapter helped me standardize my own grading system, and the business opportunities chapter gave me a realistic look at private-labeling margins that I had been fumbling through on my own. The writing is dry in the best way — no hype, just numbers and processes. Highly recommended.
