Most bags sold abroad say paella rice and stop there. That phrase names no variety, and variety is the only thing on a packet that connects to a measurement. The figure that matters is amylose, and it spans from 16.3 percent in senia to 25.6 percent in albufera.
Which rice is best for paella, bomba or senia? Bomba carries 24.9 percent amylose and senia 16.3, and that gap decides your margin for error rather than quality. The Consejo Regulador calls bomba resistant to overcooking and senia very creamy. Albufera runs highest at 25.6 percent, so it behaves like bomba.
Paella rice is a shelf category, not a variety
The Arroz de Valencia designation protects fourteen named varieties of the species Oryza sativa, and their published amylose spreads across nine percentage points. Two bags with identical front labels can therefore cook in opposite directions, one holding its grain and the other releasing starch into the pan.
Amylose is the starch that holds a grain’s structure. Higher figures keep the shape and slow down the moment it goes soft; lower figures shed starch and turn the dish creamy. The Ministerio de Agricultura prints the average for every variety in a control document that never reaches the packaging.
How to tell it is the real thing
The one checkable mark is the numbered back label. Protected rice may be sold only in packaging that carries it, with the Denominación de Origen wording on both the label and the counter-label, and in its Valencian form where used.
Behind that label sits a threshold with a figure. The specification demands a minimum of 92.70% defect-free grain and caps each fault separately: 4.00% broken mediums, 2.00% chalky and green grains, 0.50% red and red-streaked, 0.50% stained and pitted, 0.20% yellow and coppery, and 0.10% foreign matter.
Traceability comes before packaging. Only rice grown on registered plots and processed by registered firms may be sold under the designation, under the regulation ratified by the Orden of 27 June 2001 in Spain’s official gazette. It is the same logic that governs the tiger nut behind horchata, where the protection travels with the crop.
Bomba, and the one nobody exports
Bomba is the variety most English-language recipes name, and the figure behind its reputation is 24.9% amylose. What the reputation misses is that albufera sits slightly above it at 25.6%, the highest in the designation, with the same grain length of 5.2 mm.
Shape is the only measurement separating them. The length-to-width ratio is 1.8 for bomba and 1.7 for albufera, the lowest of the fourteen varieties, and both share a pearling figure of 99%.
Albufera is the younger variety and barely leaves Spain, which is why a shop abroad will almost always stock bomba instead. The Consejo Regulador de la DOP Arroz de Valencia credits bomba with resistance to overcooking and a firmness that increases as it cools, and albufera with an extraordinary creaminess that keeps the inside of the grain firm.
Senia is a different tool, not a lesser one
At 16.3 percent amylose, senia sits nearly 10 points below albufera. It measures 5.6 mm, four tenths longer than bomba, and its neighbour in the table, bahía, shares that length while reaching only 19.1 percent.
That released starch is what binds a soupy or creamy rice. The Consejo Regulador describes senia as very creamy with juicy grains and a good conductor of the stock’s flavour, so asking bomba at 24.9 percent to do senia’s work is asking it to fight its own composition.
The trade-off is warning time. A rice that sheds starch passes its point sooner and signals less, which rewards a cook who is watching the pan and punishes one who is not.
| What you want | Variety to look for | Amylose | Why it follows |
|---|---|---|---|
| Certainty about origin | any variety with the numbered back label | n/a | traceable to registered plots and processors |
| A middle option | bahía | 19.1% | sits between the two extremes |
| A creamy or soupy rice | senia | 16.3% | releases the starch that thickens the dish |
| A paella with room for error | bomba or albufera | 24.9% and 25.6% | highest in the designation, resist overcooking |
Three provinces, and what the breeze does there
The protected area covers roughly 16,000 hectares of natural wetland across three provinces. Its core is the zone of influence of the Parque Natural de la Albufera, taking in Albal, Albalat de la Ribera, Alfafar, Algemesí, Beniparrell, Catarroja, Cullera, Massanassa, Sedaví, Silla, Sollana, Sueca and València.
Beyond that core the seal reaches further than its name suggests. It includes Pego in Alicante province and four municipalities in Castellón: Almenara, Castellón, Chilches and La Llosa. The Consejo Regulador sits in Sueca, not in the city.
That geography is also the ministry’s explanation for the grain itself. Sitting between the beach line and the coastal ranges, the zone gets a night sea breeze credited with a slow ripening that stops fissures forming, and a westerly wind that acts against fungal spores such as pyricularia. Fewer fissures means fewer broken grains in milling and during cooking, since a fissured grain splits when it boils.
That regularity is what the 99% pearling figure records across all fourteen varieties, and the specification ties it to a very homogeneous and constant cooking point.
Seeing where the grain grows takes half an hour. Rice fields ring the lagoon crossed on the Albufera boat trip and run up to the dune strip at El Saler, the Central Market sells the rice beside the rest of the local produce, and the water that orders this farmland has its own institution in the water court, sitting every Thursday.
Frequently asked questions about paella rice
Is bomba really the best rice for paella?
It is the most forgiving, which is not the same thing. Spain’s agriculture ministry puts bomba at 24.9% amylose and albufera slightly higher at 25.6%, and both resist overcooking. Senia, at 16.3%, gives a creamier result but leaves a much narrower window.
What does a bag labelled paella rice actually contain?
The label alone does not say. The Arroz de Valencia designation covers fourteen named varieties of Oryza sativa with amylose ranging from 16.3% to 25.6%, so a bag that names the variety carries information and one that says only paella rice does not.
How can I tell genuine Arroz de Valencia rice?
By the numbered back label. The specification requires protected rice to be sold only in packaging carrying that numbered counter-label, with the Denominación de Origen Arroz de Valencia wording, or its Valencian equivalent, on both the label and the counter-label.
Choosing rice for a paella is choosing how much margin you want, and that margin is written in a table almost nobody opens.
