Cold brew has evolved from a specialty offering to an expected menu item. Its high margins, batch production efficiency, and growing consumer 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
The Cold Brew Advantage
| 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 |
Margin Analysis
Cold brew cost breakdown (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% |
Market Demand
Cold brew continues growing faster than overall coffee market:
- Year-round consumption increasing (not just summer)
- Health perception (smoother, less acidic)
- Caffeine content appeals to many consumers
- Premium pricing accepted
- RTD (ready-to-drink) format expanding
Production Methods
Immersion Cold Brew
How it works: Coffee grounds steep in cold water for 12–24 hours, then filtered.
Pros: simple equipment, easy to scale, forgiving process, and lower equipment cost.
Cons: long production time, large batch commitment, and requires planning ahead.
Basic recipe:
Ratio: 1:8 coffee to water (for concentrate). Grind: Coarse (like French press). Temperature: Room temp or refrigerated.
- Time: 18–24 hours
Slow Drip (Kyoto Style)
How it works: Water slowly drips through coffee bed over 8–24 hours.
Pros: visual appeal (tower display), distinctive flavor profile, and premium positioning.
Cons: equipment expensive ($500–$3,000), lower volume, more attention required, and harder to scale.
Best for: Premium positioning, visual theater, specialty focus
Rapid Cold Brew Systems
How it works: Technology accelerates extraction (pressure, agitation, etc.)
Pros: fast production (minutes vs. hours), on-demand capability, and fresh flavor.
Cons: expensive equipment ($5,000–$15,000+), flavor profile differs from traditional, and more complexity.
Best for: High volume, on-demand freshness priority

Cold Brew Recipe Development
Standard Concentrate Recipe
Target: Concentrate to dilute 1:1 or 2:1 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 concentrate makes approximately 20–25 servings (diluted)
Choosing Coffee for Cold Brew
Best characteristics: medium to medium-dark roast, chocolatey, nutty, low acid, full body, and clean, smooth finish.
Origins that work well: brazil (classic, chocolate), colombia (balanced, clean), guatemala (chocolate, smooth), and sumatra (earthy, full body).
What to avoid: light roasts (can taste sour), high-acid origins undiluted, and fruity profiles (unless intentional).
If Roasting Your Own
Roasting for cold brew offers flexibility: develop specific cold brew profile, control freshness perfectly, experiment with blends, and batch roast for production schedule.
Bellwether cold brew approach: roast weekly batch for cold brew production, create specific "cold brew roast" profile (slightly darker development), 1.5 kg batches match production needs, and ensure 5–14 day post-roast window for optimal extraction.
Scaling to Wholesale
Wholesale Opportunities
| 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 Cold Brew
Why kegs work: extended shelf life (nitrogen/CO2 environment), easy dispensing for accounts, premium presentation (nitro option), and efficient delivery.
Keg setup costs: corny kegs (5 gal): $80–$150 each, commercial kegs: $100–$200 each, nitrogen/CO2 system: $300–$500, and need 2–3× kegs of weekly volume (rotation).
Bottling Cold Brew
For retail/grocery distribution:
Bottles/packaging: $0.30–$1.00 per unit. Labeling requirements: Check state regulations. Shelf life considerations: Date coding required.
- Bottling equipment: $2,000–$20,000
Production Capacity Planning
Weekly production example:
| 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: 50 lbs/week ÷ 3.3 lbs/batch = 15 roasts/week (30 minutes labor with Bellwether)
