Rennet · Chymosin · Coagulation
Professional rennet and chymosin for cheesemakers who care about consistency, quality, and every batch they produce.
Products
Liquid and powder coagulants, chosen for the cheese you actually make — not for a marketing tier.
A liquid microbial coagulant for cheesemakers who want a straightforward, repeatable set.
A microbial rennet in powder form, for cheesemakers who prefer a dry coagulant they dissolve before use.
A liquid chymosin coagulant for cheesemakers who want a clean, well-defined curd and predictable behaviour.
Both are liquid coagulants. The honest answer is that the right one depends on the cheese you make and how you run your process — and that coagulation also depends on milk composition, temperature, pH, calcium, cheese style and process conditions. No single ingredient decides cheese quality.
| Liquid Microbial Rennet | Liquid Chymosin | |
|---|---|---|
| What it is | A microbial rennet — a coagulant produced by fermentation | A coagulant in which chymosin is the milk-clotting enzyme |
| Product format | Liquid | Liquid |
| Typical applications | Fresh Latin American cheeses, fresh farmer's cheese, mozzarella, everyday artisan batches | Styles needing a clean, well-defined curd, including semi-hard and aged cheeses |
| Fresh vs aged | Commonly chosen for fresh and quick-turn styles | Commonly chosen where the cheese is held, pressed or aged |
| Coagulation character | A clean set suited to fresh styles; behaviour still depends on milk and process | Specific action on milk protein, associated with a well-defined curd |
| Intended producer | Home, artisan and small commercial cheesemakers | Artisan through small and medium commercial production |
| Coagulating strength (IMCU) | Technical information to be supplied by Bixa. | Technical information to be supplied by Bixa. |
| Dosage | Per product label — see our dosage guide | Per product label — see our dosage guide |
Who we work with
For experienced cheesemakers refining recipes and producing high-quality cheese.
For small and medium producers focused on repeatable processes, dependable ingredients, and scaling production.
For operations where consistency, documentation, ingredient strength, dosing, and supply reliability matter.

Troubleshooting
Start with the symptom. Each guide walks the possible causes — milk, temperature, pH, calcium, dosage, storage, process — instead of blaming the rennet by default.
The Bixa Journal
The chemistry does not change. Mixing, temperature uniformity, how long cutting takes, documentation and ingredient supply all change — and those are what decide your consistency at volume.
Using ultra-pasteurized milk, or milk that is too cool, and then blaming the coagulant. In most failed-set calls we take, the problem is upstream of the bottle.
Queso llanero is a firm, notably salty white cheese from the Venezuelan llanos. Compared with softer fresh cheeses like queso de mano, it is drier and more heavily salted, which historically allowed it to keep in a hot climate.
Batch consistency comes from measuring what matters, writing it down, and changing one variable at a time. The main levers are milk quality and consistency, temperature and pH control, accurate dosing, and a stable coagulant supply.
The most common coagulation mistakes are using ultra-pasteurized milk, adding coagulant to milk that is too cool, diluting in chlorinated or warm water, stirring during the set, and changing more than one variable per batch.
Milk coagulation is the process of turning fluid milk into a gel. Clotting enzymes remove the protein layer that keeps casein micelles apart; the destabilised micelles then aggregate, in the presence of calcium, into the curd you cut.
