Cold brew has evolved from a specialty offering to an expected menu item. High margins, batch production efficiency, and growing year-round demand make it one of the most profitable additions to any coffee program. This guide covers how to build a cold brew program — from single-café production to wholesale distribution.
Why cold brew makes business sense
| Factor | Cold brew | Iced espresso |
|---|---|---|
| Production | Batch (efficient) | Per-order (labor intensive) |
| Labor per serving | Minimal (pour) | High (pull shot, steam milk) |
| Consistency | High | Variable |
| Shelf life | 7–14 days refrigerated | Made to order |
| Margin | 80–87% | 70–76% |
| Peak season demand | Very high | High |
The margin math on a 16 oz serving:
| Component | Cost |
|---|---|
| Coffee (1.5 oz concentrate) | $0.35–$0.50 |
| Cup, lid, straw | $0.15–$0.25 |
| Ice | $0.05 |
| Total cost | $0.55–$0.80 |
| Sell price | $4.50–$5.50 |
| Gross margin | 82–87% |
Cold brew demand keeps growing year-round, not just in summer. The health perception (smoother, less acidic), caffeine content, premium pricing acceptance, and expanding RTD (ready-to-drink) format all reinforce each other.
Production methods
Immersion cold brew is the simple, scalable method. Coffee grounds steep in cold water for 12–24 hours, then are filtered. Pros: simple equipment, easy to scale, forgiving process, lower equipment cost. Cons: long production time, large batch commitment, requires planning. Basic recipe: 1:8 coffee-to-water ratio for concentrate, coarse grind (like French press), room temperature or refrigerated, 18–24 hours.
Slow drip (Kyoto-style) brewing has water dripping through coffee over 8–24 hours. Pros: visual appeal (the tower is its own attraction), distinctive flavor, premium positioning. Cons: equipment is expensive ($500–$3,000), lower volume, more attention required, harder to scale. Best for premium positioning and visual theater.
Rapid cold brew systems use technology (pressure, agitation) to accelerate extraction. Pros: minutes vs. hours, on-demand capability, fresh flavor. Cons: expensive equipment ($5,000–$15,000+), flavor profile differs from traditional, more complexity. Best for high volume or on-demand freshness focus.
Equipment by scale
Small scale (café use):
| Equipment | Cost | Capacity | Best for |
|---|---|---|---|
| Cambro containers | $20–$50 each | 5–20 gallons | Simple start |
| Toddy system | $50–$200 | 1–2 gallons | Small café |
| Filtron | $150–$300 | 1.5 gallons | Quality focus |
| Brewista Pro | $300–$500 | 5 gallons | Mid-volume |
Medium scale:
| Equipment | Cost | Capacity | Best for |
|---|---|---|---|
| Bunn Infusion | $1,500–$2,500 | 5 gallons | Consistent café |
| Curtis Cold Brew | $2,000–$3,500 | 3–5 gallons | High-quality |
| Countertop systems | $1,000–$3,000 | Various | Growing volume |
Large scale (wholesale):
| Equipment | Cost | Capacity | Best for |
|---|---|---|---|
| Commercial brewing tanks | $5,000–$15,000 | 20–100 gallons | Wholesale production |
| Rapid extraction systems | $15,000–$40,000 | High volume | Large scale |
| Kegging / packaging | $3,000–$10,000 | — | Distribution |

Recipe development
Standard concentrate recipe (target 1:1 or 2:1 dilution with water/ice):
| Parameter | Specification |
|---|---|
| Ratio | 1 lb coffee : 1 gallon water |
| Grind | Coarse (30–35 on EK43, or French press) |
| Water | Filtered, room temperature |
| Steep time | 18–24 hours |
| Temperature | 65–70°F (room temp) or 38–40°F (refrigerated) |
Yield: 1 gallon of concentrate makes approximately 20–25 servings (diluted). Choose coffee with medium to medium-dark roast, chocolatey or nutty notes, low acid, full body, and a clean smooth finish. Origins that work well: Brazil (classic, chocolate), Colombia (balanced, clean), Guatemala (chocolate, smooth), Sumatra (earthy, full body). Avoid light roasts (can taste sour), high-acid origins undiluted, and fruity profiles unless intentional.
If you're roasting your own, develop a specific cold brew profile (slightly darker development), use 1.5 kg Bellwether batches that match production needs, and ensure a 5–14 day post-roast window for optimal extraction.
Scaling to wholesale
| Channel | Format | Volume | Pricing |
|---|---|---|---|
| Cafés without cold brew | Kegs | 5–15 gal/week | $45–$60/gallon |
| Restaurants | Kegs | 5–20 gal/week | $40–$55/gallon |
| Grocery / retail | Bottles | Varies | $3–$5 wholesale |
| Office accounts | Kegs | 2.5–10 gal/week | $50–$70/gallon |
Kegging works well for wholesale because nitrogen or CO2 environments extend shelf life, dispensing is easy for accounts, presentation can be premium (nitro option), and delivery is efficient. Setup: corny kegs (5 gal) at $80–$150 each, commercial kegs at $100–$200, nitrogen/CO2 system at $300–$500. Plan for 2–3× kegs of weekly volume to allow rotation.
Bottling for retail and grocery distribution: bottles and packaging at $0.30–$1.00 per unit, labeling requirements vary by state, date coding required for shelf life, bottling equipment from $2,000–$20,000 depending on scale.
Production capacity planning. A typical week:
| Use | Volume | Coffee needed |
|---|---|---|
| Café sales (100/week) | 15 gallons | 15 lbs |
| Wholesale (3 accounts) | 25 gallons | 25 lbs |
| Retail bottles (50/week) | 10 gallons | 10 lbs |
| Total | 50 gallons | 50 lbs |
Roasting requirement at 50 lbs/week: 50 ÷ 3.3 lbs/batch = 15 roasts/week, or about 30 minutes of operator labor on a Bellwether.
Menu offerings
| Item | Description | Price range |
|---|---|---|
| Cold Brew | Classic, served over ice | $4.00–$5.00 |
| Cold Brew (large) | Size upgrade | $5.00–$6.00 |
| Nitro Cold Brew | Nitrogen-infused, creamy | $5.00–$6.50 |
| Cold Brew + Milk | Splash of milk/cream | $4.50–$5.50 |
| Flavored Cold Brew | Vanilla, caramel, etc. | $5.00–$6.00 |
Seasonal and specialty options expand the menu without expanding the production line: pumpkin cold brew (fall), peppermint (winter), cold brew lemonade (summer), Vietnamese cold brew (year-round), cold brew float (summer).
Nitro cold brew is worth adding. The premium pricing ($1–$1.50 more) is justified by the creamy texture without dairy, visual appeal (cascading pour), and clear differentiation. Equipment: nitrogen tank and regulator ($200–$400), nitro tap or faucet ($100–$300), keg system ($200–$400).
