Cold Brew Blend — Built for Sweetness, Strength & Stability

Cold brew flips extraction, acidity, and shelf life. This blend is engineered to taste rich, smooth, and sweet when brewed cold — never just “hot coffee over ice.”

What Cold Brew Does to Coffee (And Why the Blend Matters)

Cold brew extraction (hours in cool water instead of minutes in hot) changes which compounds show up in the cup:

  • Acidity feels softer: bright coffees calm down; harsh coffees can taste dull or bitter.
  • Body and sweetness stand out: fudge, caramel, and nut notes carry the experience.
  • Oxidation and storage: the brew may sit in the fridge for days, so staling shows fast.

That’s why we design a specific cold brew blend instead of using leftovers: it needs to taste great straight, over ice, with milk, and on day three in the fridge.

Cold vs. Iced

Not Just “Iced Hot Coffee”

Cold extraction Different chemistry Flavor stability

Iced coffee can be fun, but it’s built on hot extraction. Our Cold Brew Blend is formulated for long, cool steeps: dense sweetness, low bite, and a finish that stays kind even as it warms in your to-go cup.

How We Design the Cold Brew Blend

Origins & Profile

Comfort-Forward Architecture

  • Chocolatey Brazils / Latins as the base for body and cocoa.
  • Supporting coffees selected for caramel, nut, and dried-fruit sweetness.
  • Optional naturals only when they taste clean — no heavy ferment or vinegar tones.

The target: fudge, caramel, toasted nut, gentle dried fruit — with enough structure to handle dilution and ice.

Why It’s Different

Roasted for Cold Extraction

  • Optimized for high solubility in long, cool steeps.
  • No hollow mid-palate; no sharp bite when chilled.
  • Designed to remain sweet as it sits in the fridge or in a keg.

You can still brew it hot (it’s cozy as drip), but cold brew is where the architecture really clicks.

Components will rotate with harvests, but each Cold Brew Blend release will list current origins, processing styles, and roast notes so you can see exactly how this dessert-adjacent profile is being built.

Brew Methods, Ratios & Service Tips

Concentrate

  • Ratio: 1:5–1:6 coffee:water (by weight).
  • Steep: 12–16 hours in the fridge or cool room.
  • Serve: dilute ~1:1 with cold water or milk; adjust to taste.
  • Grind: coarse to medium-coarse; avoid too many fines.

Ready-to-Drink

  • Ratio: 1:12–1:15 coffee:water.
  • Steep: 12–16 hours; stir or gently agitate a couple of times.
  • Serve over ice or with milk — it should stay sweet, not hollow, as the ice melts.

Storage & Service

  • Refrigerate immediately after filtering; airtight container.
  • Best within 5–7 days; peak flavor is usually days 1–4.
  • Nitro service? Label clearly if you add sweeteners or flavors.

Cold Brew Blend FAQ

Can I hot-brew this blend?
Yes. It’s naturally chocolate-forward and comfortable as drip or press. But its roast level and component choices really shine in cold extraction, where sweetness and texture are the stars.
Why is acidity lower in cold brew?
Cooler water and longer steeps extract fewer of the bright, volatile acids that show up in hot pour-over. That’s why we lean into coffees with good sweetness and body instead of chasing high acidity for cold brew.
Paper filter, metal, or cloth?
Paper gives a cleaner, lighter texture and can highlight chocolate and caramel. Metal or cloth keep more oils for a heavier, rounder mouthfeel. The blend is built to work with any of the three — choose based on the experience you want.
Do you add flavoring or sugar?
No. The Cold Brew Blend is unflavored coffee. All chocolate, caramel, and fruit notes come from the coffees and roast. Any syrups or milks are added at service and labeled clearly.
