The Complete Guide to Smooth, Low‑Acid Cold Brew Concentrates
What Is Cold Brew Concentrate?
Cold brew concentrate is made by steeping coarsely ground coffee in cold or room-temperature water for 12-24 hours, then filtering to obtain a thick liquid with 4-7% total dissolved solids (TDS).
Key characteristics of cold brew concentrate include:
What Are the Benefits of Coffee Concentrate?
Coffee concentrate is the easiest way to get great coffee (fast). Because it’s pre-brewed and ultra-flavorful, you just add water or milk and you’re sipping in seconds (iced or hot).
It’s naturally smoother and lower in perceived acidity than many hot brews, so it tastes rounder and is easier on the palate. You also get consistency: every pour starts from the same strong base, which means fewer “oops” cups.
Coffee concentrate is versatile. You can dial strength with simple ratios (1:3 for iced coffee, 1:2 for lattes), or use it in cocktails, baking, sauces, and protein shakes without introducing extra bitterness. It’s efficient too, with less gear, less mess, and less wasted beans compared to brewing a full pot you don’t finish. Stored in the fridge, it keeps well, so you can batch (or buy) once and enjoy all week.
How Does Cold Extraction Reduce Acidity?
Cold water extraction is gentler on your beans and your taste buds.
Brewing cool pulls out fewer chlorogenic acids and other acidic stuff, so the flavor stays smooth and rounded. It also slows how quickly caffeine and organic acids dissolve, which is why cold brew feels softer and more balanced in the mouth.
Fun fact: Cold brew usually sits around pH 6.0-6.5, while hot coffee is closer to 5.0-5.5.
Cold Brew Versus Hot Brew and Espresso
Cold brew's longer extraction time compensates for lower temperature, resulting in higher TDS and lower acidity.
Typical Caffeine and TDS Levels
Cold brew concentrate is mighty by design. One 30 ml serving usually lands around 150-200 mg of caffeine. Mix it 1:3 with water or milk, and you’ll get roughly 50-65 mg per 8-oz cup, which is right in the zone of a regular coffee, minus the harshness.
The sweet spot sits around a TDS range of ~4-7% so flavors stay bold, clean, and balanced.
What Affects Coffee Concentrate Flavor and Acidity?
Coffee flavor and acidity come down to a few basics, like pH, the beans and roast, brew time, and water quality.
Your ratio (coffee to water) and any dilution set the strength. Fresh beans and clean, mineral-balanced water keep the cup clear and consistent. Adjust these levers to make your coffee smoother, sweeter, or brighter.
pH and Total Dissolved Solids
pH levels affect perceived acidity and flavor. Cold brew maintains a pH of 6.0‑6.5, offering a gentler taste.
Total dissolved solids (TDS) contribute to body and smoothness, with the ideal range of 4‑7% TDS providing:
Higher TDS levels enhance viscosity and sweetness, while lower levels may taste thin.
Bean origin and variety impact
Arabica beans are preferred for cold brew due to their naturally lower bitterness. Optimal bean origins include:
These beans naturally produce lower chlorogenic acid levels, ideal for smooth concentrates.
Roast level effects on acidity and bitterness
Water chemistry and filtration
Water quality impacts extraction and flavor. Ideal hardness is 50‑150 ppm calcium carbonate:
For the best flavor, focus on using:
You’ll generally want to avoid distilled water (flat) and hard tap water (harsh flavors). Proper water chemistry ensures consistent extraction and helps maintain the low-acid profile.
How To Choose the Right Beans and Roast for Low‑Acid Brew
Choosing beans for a low-acid brew is key. Here’s a general look at what to keep in mind.
Low‑acid bean profiles
Selecting low-acid beans is crucial for smooth cold brew concentrate. Top varieties include:
These beans have lower chlorogenic acid content, enhancing sweetness and body.
Medium vs. dark roast for smoothness
Single origin versus blends
Single origin coffees showcase unique flavors, while blends balance acidity, body, and flavor consistency.
Master roasters create:
Blends often provide better consistency for commercial production, while single origins appeal to specialty markets.
Freshly roasted versus pre‑ground
Freshly roasted beans maximize flavor. For optimal results:
Pre-ground coffee may lose flavor, increasing bitterness. Use only if:
Investing in fresh beans pays off in concentrate quality.
Can You Make Your Own Low‑Acid Cold Brew Concentrate?
With a bit of kitchen skills, you can technically make your own low-acid cold brew concentrate at home — though it may not have the same volume of flavor as high-quality brands like Javvy!
You’ll need:
For concentrate, focus on a 1:4 ratio of coffee to water by weight (ex: 125 g coffee to 500 g water). For ready-to-drink cold brew, dilute your concentrate 1:3 to 1:4 with water or milk.
Grind Beans and Add Water
Start by grinding your beans to a coarse texture — think sea salt or breadcrumbs. A coarse grind slows extraction and helps keep acids in check. Add grounds to your jar, pour in filtered water, and stir to fully wet the coffee.
Cap the jar and let it steep at room temperature for 12-16 hours or in the fridge for 16-24 hours. Cooler, slower brews tend to taste rounder and less sharp.
Strain and Taste
When time’s up, strain. If you used a French press, press gently; don’t force it. For the cleanest cup, run the brew through a paper filter or a tight-weave bag. Less fine sediment = smoother mouthfeel and fewer bitter notes over time.
Taste your concentrate. It should be bold but not harsh. If it’s too sharp, the next batch can go a touch coarser or steep for an additional two to four hours. If it’s flat or woody, shorten the steep or use slightly fresher beans. Store the strained concentrate in a sealed container in the fridge for up to 7-10 days.
To serve, start with 1 part concentrate to 3 parts water or milk, then adjust. Ice will naturally dilute, so don’t be shy about making your first sip a little stronger.
Want it to be extra smooth? Add your favorite creamer or a pinch of salt to round out the edges.
Quick Tips
We’ve got a few extra tips for the best experience:
Storing and Maintaining Coffee Concentrate
A little care goes a long way toward keeping your concentrate tasting clean and balanced. Store it cold, keep air and light out, and use it within its best-by window.
Ideal Refrigeration Practices
Keep your concentrate in the fridge at 2-4°C (cold, but not freezing). Try to avoid temperature swings from frequent door opening — steady temps help preserve flavor.
Pour into a container that seals tightly and fills up most of the way to minimize headspace (less oxygen = less staling). Label the jar with the brew date so you know when it’s at its peak.
Need more time? Freeze portions so you only thaw what you’ll use.
Choosing a Container
Dark glass and stainless steel are ideal, as they block light and don’t hold onto odors.
Skip clear plastic (lets light in) and regular plastic that can absorb or leach smells over time. Whatever you use, airtight seals are the real hero against oxygen.
Refreshing Stale Concentrate
You can “refresh” a tired batch: brew a fresh cold brew using the same beans and ratio, then blend 1:1 (stale:fresh) and pass it through a fine filter. It’ll perk things up, but nothing beats a truly fresh concentrate.

Low‑Acid Coffee Concentrate Drink Ideas
Low-acid cold brew concentrate is a flexible base you can tune to your taste — iced, hot, cocktail… or dessert.
Dilution Ratios for Iced Coffee and Lattes
For everyday iced coffee, go 1 part concentrate to 3 parts cold water (i.e., 60 ml concentrate + 180 ml water over ice). It’s smooth, balanced, and gentle on the stomach. Prefer a creamier sip? For a cold brew latte use 1:2 with milk (i.e., 60 ml concentrate + 120 ml milk).
Hot Coffee
Yes, you can make a low-acid hot cup. Warm the concentrate gently (≤70°C / 160°F) and combine 1:1 with hot water.
