Your first puré can feel messy: wrong temperature, stuck flow, weak cerveza. That stress grows on día de la cerveza. The fix is a well-designed tina de macerado with simple controls. Build it right, and the puré turns calm, steady, and predictable.
A tina de macerado is the vessel where crushed malt mixes with hot water so enzymes convert starch en sugar, creating sweet mosto para cerveza. In plain terms, it’s a heated, insulated tub with a false bottom y un válvula to drain clear mosto, ready for the boil.

What is a mash tun in beer brewing?
In the proceso de elaboración, the tina de macerado holds crushed grano and hot licor while the enzymes work. It’s the central piece of equipment that sets up your whole cerveza for success. If the puré hits the right temperature, you’ll pull the flavors and sugars you need for great beer.
Some brewers use a dedicated cuba de filtración for runoff, but many combine mashing and lautering in one tina de macerado. During lauter you recirculate until the flow of wort runs clear, then drain to the kettle. Good filtración inside the tun prevents husk bits from reaching the boil.
How does the mashing process work?
En mashing process is simple: warm water meets crushed malt, and enzymes begin their enzymatic work. A single-temperature infusion puré (a “single infusion”) is the most common. Keep temperature steady and you’ll get reliable eficacia and a clean run-off of clear mosto.
Strike water ratio and molienda crush matter. Too fine and you risk a stuck lauter; too coarse and you lose eficacia. For most beers, target a middle-of-the-road crush and a steady puré rest. Managing calefacción gently avoids overshooting your temperature window and protects flavor.
Mash tun types (cooler vs stainless vs electric): a practical comparison
Como Brewing Equipment Manufacturing factory, we build and test a range of cubas de macerado for home and pro use. Below is a quick side-by-side to help you choose.
| Tipo | Material | Typical Capacity | Método de calentamiento | Aislamiento | Internal Screen / false bottom | Valve | Lo mejor para | Trade-offs |
| Picnic cooler build | Plastic + foam | 5–10 gallon | Pre-heated strike water | Excellent passive | Stainless or mesh filtro plate | 1/2″ ball valves | Budget, homebrew | Limited direct calefacción control |
| Stainless steel mash tun | Acero inoxidable | 10–30 gallon | Direct-fire / RIMS / HERMS calefacción | Jacket or wrap | Perforated false bottom | 1/2″ or 3/4″ válvula | Repeatable, scalable | Higher cost |
| Electric, jacketed vessel | Acero jacket | 1–10 bbl | Electric elements + jacket calefacción | Built-in | Laser-cut screen + filtración bed | TC butterfly válvula | Pequeño cervecería | Power requirements |
Notes: Cooler builds are cheap and work well, but control comes from water prep, not live calefacción. Acero inoxidable systems add durability and precision. Electric jackets give tight temperature control for consistent cerveza quality.
Capacity, diameter, and dimension: planning your size
Sizing your tun depends on recipe gravity and lote size. For 5 gallon gallon batches, a 10-gallon cooler or a 10–15 gallon pot is common. Leave headspace so you can stir, sparge, and recirculate without spills.
Think about diámetro and bed depth. A wider tun spreads the grain bed thin; a taller tun deepens it. Choose a dimension that balances flow and clarity. Too shallow can lead to poor bed formation; too deep can slow runoff.
Inside the tun: screens, false bottoms, and the flow of wort
The inside hardware shapes your runoff. A dome-style false bottom with tight holes supports the grain bed while letting mosto pass. A manifold or bazooka tube adds a second filtro layer. Together they support lautering and protect pumps from debris.
Use a smooth, full-port válvula to avoid shear and keep the flow of wort steady. Tri-clamp fittings and a short hose run help sanitation. If you want fast cleaning, choose a removable screen and quick-disconnects.
Heating and insulation: keeping mash temperature rock-steady
Control is everything. With a direct-fire pot you’ll nudge calefacción in short bursts while stirring the puré. With HERMS or RIMS you pump mosto through a heated coil or tube for gentle calefacción. Electric jackets give the most even calefacción and the lowest chance of scorching.
If you don’t have jackets, add insulation. Wrap the tun, close the lidy insulate seams. A simple blanket helps hold temperature on a cold day. Silicone probe grommets reduce heat loss and keep your seal tidy while you monitor the rest.
Sparge and lauter: getting clear wort with high efficiency
After conversion, sparge with 168–170°F water to rinse sugars. Fly sparge gives control for big beers; batch sparge is fast and simple. Either way, aim for steady runoff and stop when gravity drops. That protects flavor and helps eficacia.
Recirculate until the mosto clears, then sparge slowly to avoid compacting the bed. Keep the surface of the puré a little above the grain bed during lautering. A careful sparge schedule is the simplest upgrade for clarity and yield. One gentle sparging step can make the difference.
From mash to kettle: transfer, boil, and hops
Open the válvula and move the clear mosto to your hervidor de cerveza o boil kettle. Short, smooth lines and a food-grade hose help flow. Boil firmly, add your saltar charge on time, and chill quickly for clean flavor.
If you’re stepping up from homebrew to a pilot cervecería, keep your transfer routine the same each día de la cerveza. Consistency across the pava, pumps, and chiller protects quality from batch to lote.
Build details that matter: fittings, silicone, and easy cleaning
Choose solid hardware. Food-grade silicone tubing is flexible and high-temp. Full-port ball or butterfly válvula options keep passages wide. Tri-clamp ferrules speed change-overs and reduce leaks.
Go for smooth welds and sanitary corners so the tun is fácil de limpiar. A lift-out screen and a rinse-down spray save minutes after a long cerveza. Keep a spare hose set on hand to avoid mid-day surprises.
The cooler mash tun: simple, affordable, reliable
The classic picnic cooler tina de macerado is a budget hero. Pre-heat it, dough-in, close the lid, and let the infusion do the work. With good prep, a cooler holds temperature for an hour with no active calefacción at all.
If you’re a new homebrewer, a cooler lets you start all-grain brewing fast. Add a screen, tighten fittings, and you’re brewing great beer. Later, you can upgrade to pumps or a stainless pot without changing your recipes.
The stainless route: durability and precision
A welded steel kettle with jacket or direct-fire ring gives long life and control. Pair it with a dial or digital probe for accurate temperature reading. Recirculation helps uniformity and can boost eficacia with the right pump speed.
Pilot systems in acero inoxidable scale well to a small cervecería. When you’re ready to upgrade, keep your as a hot-step tank or as a dedicated cereal puré vessel.
Common mistakes and quick fixes
- Stuck mash: Open the válvula slightly, stir gently, add rice hulls, and recirculate until the mosto clears.
- Low efficiency: Check crush, sparge rate, and temperature estabilidad.
- Astringency: Don’t over-sparge and avoid very hot water late in runoff.
“Start simple and repeat what works.” That’s advice we share often with every cervecera we meet.
Small manufacturer insight: what we build into our mash tuns
We engineer for clarity and control:
- Laser-cut screens for smooth filtración and steady lauter.
- Full-port ports and sanitary válvula choices for unrestricted flow.
- Jacketed options or external coils for precise calefacción.
- Modular internals that are removable for cleaning.
Because we manufacture systems end-to-end, we design each part to work as a system, not just a standalone piece of equipment.
Mini case study: 5 gallon batch on cooler vs stainless
- Enfriador build, 10-gallon tun: Single-step puré, passive hold. Clear mosto after 10 minutes of recirculation.
- Acero pot with pump: Controlled recirc, step rest. Slightly higher eficacia and faster runoff.
Both made balanced cerveza. The difference showed most on repeatability and time savings on día de la cerveza.
Glossary and quick specs
- Puré: Hot water + crushed malt rest that creates sugar.
- Sparge: Rinsing step to collect more mosto.
- Buque: The physical tank—tun, pot, or jacketed unit.
- Hervidor: Where you boil and add hops.
Typical home puré bed height: 8–14 inches. Typical plumbing: tri-clamp ports, sanitary valves, and high-temp tubing with strong seal. Recommended diámetro depends on volume; ask for sizing before you upgrade capacity.
Preguntas frecuentes
Can I start with a cooler mash tun and still make quality beer?
Yes. A cooler holds heat well and supports a clean puré. Add a solid screen, keep your temperature steady, and manage your sparge. Many brewers win medals with cooler setups.
Do I need recirculation to get clear wort?
No, but it helps. Gentle pump-back through the bed brightens mosto and improves runoff. Keep rates modest to avoid compressing the grano bed.
What’s the best way to heat my mash?
Direct-fire works with care; electric jackets and HERMS give the most even calefacción. Choose what fits your space, power, and budget.
How do I size a mash tun for 10 gallon batches?
Plan for headspace. Many choose 15–20 gallon tuns for high-gravity gallon batches. Match bed depth and diámetro to your recipes and pump flow.
What fitting upgrades help most?
Full-port válvula options, quick-disconnects, and tri-clamps. Food-grade silicone tubing and tidy routing make cleanup faster.
Can I clean it fast after a long brew?
Yes. Choose smooth welds, lift-out screens, and rinse-down access. That keeps parts fácil de limpiar and extends life.
