1. What Is a Unitank and Why Do Many Craft Brewers Swear by “One Tank” Workflow?

A unitank (sometimes written unitanks) is a conical beer tank that handles primary fermentation, conditioning, and carbonation inside a single vessel. These tanks are called the “Swiss Army Knife” of the cellar because the beer goes from a fermenter to finished package without ever moving lines.

Because the cone lets yeast to accumulate at the bottom, the brewer can dump trub, harvest healthy cells, or place the tank under pressure for natural carbonation. This brewing process by removing transfers is sanitary and reduces oxygen pickup—key for stable craft beer flavors.

 Imagine cutting transfer time in half while doubling turns on your brewhouse. That’s the appeal of using a unitank and a brite tank alternative in one shell. As manufacturers of quality brewing equipment, we design jacketed 3–300 bbl unitanks that reach ±0.1 °C stability—precision that keeps hop aromatics alive.

2. What Does a Brite Tank Do & How Does It Produce Clear Beer That Sparkles?

A brite tank—also spelled bright tank—is a straight‑cylindrical vessel used after primary fermentation and aging tanks. Once you move the beer off yeast, cold temperatures and finings polish the liquid; brite tanks allow the final CO₂ adjustment so carbonated beer hits spec for kegs and cans.

Because tanks have a simpler design (no cone), operators can CIP quickly, load much beer, and keep the cellar turning. That’s why large facilities planning to package and distribute barrels of beer every week still “look at a brite” for the finishing step.

3. Unitank vs Brite Tank—Side‑by‑Side Specifications

	Unitank	Brite Tank
Primary Task	Ferment, age, carbonate	Clarify, carbonate, package
Bottom Geometry	Conical fermenter 60 °	Flat bottom
Pressure Rating	2–3 bar (typical)	3–4 bar
Workflow Transfers	None (“one tank”)	1: fermenter to a brite
Oxygen Exposure	Minimal	Low if sealed
Cellar Throughput	Higher (less equipment)	Higher clarity per batch
CapEx per Barrel	$$	$
Best For	Taproom‑centric, flexible SKUs	Larger quantities of beer, distro lines

Quote from Head Brewer, Sparrow Brewing:

“Switching to 30 bbl unitanks cut our cellar hoses by 80 %. Every time beer may leave a vessel, we ask if we can keep it inside the same tank instead.”

4. How Tank Shape Influences Yeast Health, Clarification, and Carbonation

The unitank cone supports yeast‑driven diacetyl reduction while pressure holds aromatics. By contrast, the flat bottom brite tank is the shape that maximizes surface area for cold crashing, which produces a clearer beer in 24 hours.

When you fermenting in a brite (some nano‑brewers do this to save cash), yeast remains in the beer while it ferments, but dumping trub is harder. Most pros move the beer once gravity stabilizes—brewery equipment such as gentle centrifugal pumps keeps shear low.

Stats snapshot:

• 30 μm fine beer filter cartridges remove 90 % haze but cost $0.012 per pint.
• A 15 bbl unitank under 1 bar achieves the same clarity if held at ‑1 °C for 36 h.

5. When Should Startup Craft Breweries Use Unitanks?

If you need to launch 12 core SKUs with limited floor space, unitanks work well because you package beer directly from the same steel. That means less equipment, fewer glycol drops, and quicker CIP cycles—savings you can pour into recipe R&D.

Case study: A 3 bbl brewpub in Texas upgraded to 5×5 bbl unitanks, freeing capital to add a can seamer. In six months they doubled revenue without adding staff. They note that “every time beer is taken from the cellar we ask: did it leave oxygen‑free?” The answer is yes—because there was no moving beer.

6. When Do Brite Tanks Become Essential for Packaging & Distribution?

If you plan on packaging and distributing dozens of keg pallets per week, adding dedicated brite tanks also speeds throughput. You can crash‑cool overnight, test CO₂, and run the canning line while the fermenter fills with fresh wort, which frees up the fermenter and keeps the brewhouse boiling.

Table – Production Math Example

Weekly BBL Target	Fermenters Only	+2 Brite Tanks	Delta
60	6 ×10 bbl unitanks	4 ×10 bbl fermenters + 2 ×20 bbl brite	+20 % volume

A brew master should weigh utility bills too: brite chilling draws 18 % less glycol per barrel because tanks have a very simple surface‑to‑volume ratio.

7. Can You Brew and Package Straight From One Tank Without Compromise?

Yes—modern unitanks and bright tanks share sanitary design and 3‑A certified components. When you use unitanks with a floating racking arm, you can drain clear beer off the cone, filter out later if needed, and finish packaged carbonated beer at <20 ppb O₂.

However, beer outside a sealed loop risks staling. If your cellar layout forces hoses across a hot dock, exposed to the open air or exposed to other contaminants, sticking with a closed‑loop unitank system eliminates that threat.

8. Cost, Space & Workflow: Decision Checklist for Brewers

Brewer priorities differ. Use this quick test:

• Do you serve most craft beer onsite? → Pick one tank versatility.
• Do you produce larger quantities of beer for distribution? → Add brite capacity.
• Is footprint limited but ceiling high? → Stackable unitanks save floor.
• Do you expect to expand to barrels of beer >5,000 bbl/yr? → Hybrid cellar (fermenters + brite) scales better.

Chart below shows ROI crossover (CapEx vs throughput) for 10, 30, 60 bbl plants.

9. Real‑World Workflow: “Beer From One Tank to Tap” at Coastal Cider House

Coastal Cider House brews 15 bbl wild‑fermented cider twice a week. By adopting 6×30 bbl unitanks, they eliminated a transfer step, cut DO from 80 ppb to 18 ppb, and hit shelf life goals in supermarkets 800 km away. They now say: “Our brewing and packaging processes run in half the labor hours.”

Yet when seasonal demand spikes, they lease an external brite tank to crash three limited ciders simultaneously, proving that unitank vs brite isn’t either‑or—it’s strategic flexibility.

10. FAQs on Unitanks & Brite Beer Tanks

Is the only difference between a unitank and a brite tank the cone?
Not exactly. Geometry, pressure rating, and task define them. The cone does help dump yeast, but a brite tank often holds higher service pressure for rapid carbonation.

Does beer off yeast taste cleaner?
Yes. Removing sediment reduces sulfur pickup and lets hop oils shine; clearer beer also photographs better for marketing.

Can I fermenting beer in a brite tank?
You can, yet making unitanks impractical for some startups; you’ll lack cone benefits and risk clogging drains.

How do I carbonate inside a unitank?
Attach a stone to the bottom port, chill to ‑1 °C, and inject CO₂ at 15 psi until you hit 2.5 vol. The process may take 6–18 h depending on volume.

What internal finishes protect against contaminants?
All our surfaces are Ra ≤ 0.4 µm; we polish weld seams so beer may slide off sanitary smooth walls, lowering bio‑film risk.
