Ice coffee and cold brew coffee are NOT the same thing. I hope you already know this, but if not: this graphic will show you why. Both have pros and cons, but to be honest, cold press/brew coffee is what its all about.

Cold brew coffee has been exploding in popularity during recent years, and for good reason. Compared to regular old iced coffee, the cold brew is a very different beast, and many coffee fans are finding that they actually like it more.
When it comes to preparation, iced coffee and cold brew are polar opposites. While an iced coffee is prepared hot and then chilled, a cold brew is made at a low temperature, relying on time instead of temperature.
The science behind the brewing process means cold brews are generally less acidic and more mellow than regular coffee.
- Easy and quick to make - you just need hot coffee, ice cubes and 15 minutes
- No need for a special coffee maker
- Hot water extraction creates acidic and bitter flavour compounds
- Temperature change makes it spoil faster
COLD BREW COFFEE
- Straightforward to make
- Smooth flavour profile, low in acidity
- Strong and prolonged caffeine kick
- Patience required - takes up to 24 hours to make
- You need a cold brew coffee maker
Whats all the hype around cold brew?
- It's more mellow and less acidic than hot and iced coffee...making it easier to drink.
- You get a slower releasing caffeine hit, when compared to hot brewed coffee. No caffeine crash!
- Some people also find it more stomach-friendly for the same reason.
- Properly brewed cold brew lasts for up to two weeks, so you can make a huge batch at once and make up for the long brewing time
- You can also make a cold brew extract, which can be diluted or used in various recipes.
- There are tonnes of recipes ideas you can experiment with once you have a big batch of concentrate.
The Science Behind Cold Brew (and why it tastes better)
A lot of nice sounding benefits are attached to cold brew - it tastes awesome, it’s smooth and non-acidic, it’s better for the stomach...
You might be wondering if this is all just marketing talk to sell a new form of coffee. Its not!
There are actually simple, scientific reasons for the positive attributes of a cup of cold brew.
As you may know, the science behind a good cup of coffee is actually quite complicated.
Coffee beans contain roughly a thousand different chemical compounds, including malic acid (a sour compound also found in green apples) and Furaneol (a sweet compound also found in strawberries).
Making coffee is really the process of extracting these compounds from the beans into the water, thus turning it into the beverage we know and love.
There are two important factors to control in the brewing process:
TIME and TEMPERATURE.
This is where cold brew is interesting, because the brewing process is completely different from a traditional brew in both aspects.
Let’s take a look at what actually happens during the brewing processes:
In hot water, the coffee compounds are released rapidly, meaning the brewing process is completed within just a few minutes.
On the flip side, the higher temperature also causes the coffee acids and oils to degrade and oxidize more quickly.

This can accentuate the acidity and bitterness of the coffee.
Conversely, the cold brew method relies on a long brewing time instead of high temperature. This produces a completely different flavour profile, one that is smooth and mellow. This is because many of the sweeter flavour compounds are soluble even in cold water, but the oils and the acids are not.
Cold brew coffee is definitely “strong” in terms of the grounds-to-water ratio and caffeine content, but it does not taste harsh or bitter. This is why it turns out that cold brewing is an excellent method of extracting coffee beans. It is even possible to get a decent cold brew from older beans that would otherwise produce a terrible cup of hot coffee.

COMMON COLD BREW MISTAKES
Ready to start cold brewing? Just read through this list of the most common mistakes first, so you’ll be wise enough to avoid them from the get-go!
Share this Image On Your Site
MISTAKE - Using the WRONG Grind Size
Grind size is one of the most important factors when you want to achieve a perfect cup of coffee.
Cold brew is no exception.
In this case, you want to make sure your beans are ground coarsely and as evenly as possible.
I'll repeat that: YOU WANT A SUPER COARSE GRIND
If you use fine grounds, they will extract too efficiently, resulting in bitter coffee.
Moreover, using fine grounds in an immersion brew will result in a very sludgy cup (although double filtering can fix this)
You’ll need a good grinder to ensure an even grind size. If your grounds are uneven, you will probably end up with some sneaky coffee particles in your cup and this blows.
AVOID THIS COMMON MISTAKE EASILY: USE A SUPER COARSE GRIND TO MAKE COLD BREW.
MISTAKE - Using The Incorrect Ratio
Making cold brew is forgiving, so its tempting to just throw mathematics out of the window.
If you want to make cold brew that melts in your mouth, you should be aiming for a 7:1 ratio of water to coffee grounds.
If you’re making concentrate, the ratio is usually 1:1.
The most common error is skimping on the coffee grounds. Yes, you really do need that much.
If it feels like a waste, don't use the most expensive coffee beans you can find, use something mid range.
If you make it too strong, it’s no big deal, because you can always dilute it with ice or water before drinking.
Weak cold brew is much trickier to salvage, so it’s best to avoid this mistake altogether.
AVOID THIS MISTAKE: FOLLOW THE CORRECT RATIO
MISTAKE - Impatience (while steeping)
The home coffee brewing game is no game for an impatient brewer. If you're the impatient type, you should be drinking instant coffee. Im not sure you how ended up reading this in the first place.
Because cold brewing relies on time, not temperature.....you should be prepared to wait.
If you are impatient in nature, and you want cold brew NOW, go and buy a bottle of it, drink it, and then start brewing your own. This will stop the urge to end the steep time prematurely.
Cold brew coffee is beloved for its rich and smooth intensity, but you’re not going to achieve that flavour profile if you rush it.
In this case, patience is rewarded - but don’t overdo it either, because it will over-extract and turn bitter or stale.
As a rule of thumb, you should be waiting between 12 and 24 hours.
AVOID THIS MISTAKE - ALWAYS STEEP FOR 12-24 HOURS.
MISTAKE - Wrong Beans!
Some people say that you should make cold brew with cheap quality beans - because you'll be using a large amount of coffee beans, and thus, using good beans can get expensive.
I don't agree with this.
If you want to save a few bucks, go ahead and make cold brew with cheap beans. Then go ahead and 'enjoy' your cheap tasting cold brew.
The nicer the bean, the nicer the flavours. Cold brewing brings out those flavours, so choose something with a unique flavour profile.
In general, cold brew eliminates acidity.... and light roasts tend to be more acidic. This means using light roasts in your cold brew batch allows you to enjoy light roasts with the acidity.
Choose an exotic bean with a cool sounding flavour profile, and choose a lighter roast.
AVOID THIS MISTAKE - CHOOSE BASED YOUR BEANS BASED ON FLAVOUR, NOT PRICE.
MISTAKE - Storing Your Cold Brew For Too Long
Although one of cold brew’s biggest strengths is that it can be made in big batches and stored, don’t get ambitious and overdo it.
Undiluted cold brew can last for 1-2 weeks, but not longer than that.
It’s not about health and safety as much as it is about taste: the flavour of cold brew will start to degrade in just a couple of days. You cold brew will start tasting funky, and you've just wasted a whole lot of coffee.
if you add milk to your cold brew, it will go bad much faster, as dictated by common sense. If milk is your thing, only add it when you are about to drink it.

Using a coffee make that was designed with cold brew in mind will achieve 2 things. It will:
- Allow you to make unbelievably smooth tasting cold brew while you experiment with variables, and;
- Make brewing cold brew much easier and faster.
Before you rush out and buy the first cold brew coffee maker you see online or in-store, browse our recommended brewer reviews here:
The filtron is an ugly looking although EFFECTIVE cold brewing powerhouse.
It can make large batches of cold brew concentrate, which you can then store in your fridge and use to dilute into a smooth tasting cold brew.
The Filtron is a favourite of those who need lots of cold brew, and lots of GREAT tasting cold brew at that - it uses a great system with double filters.
Like the Filtron - the Toddy cold brew system was designed to one thing well: make high quality cold brew coffee concentrate.
You shiny gimmicks, no fancy glass dripping thing-a-mabobs, just a way to make super smooth cold brew, easily.
Read our review of the Toddy and see if its right for you. To be honest, there is no real difference - one is black, one is white, and they do the same thing in almost exactly the same way.
The OXO Brewer
The Oxo brewer is our favourite option for the simple reason that its convenient to use.
The unique design of the OXO system makes it portable, light, easy to store and easy to fit in the fridge while letting it do its thing.
If you like to enjoy cold brew a few times per week, and want something that looks somewhat sexy, the OXO brewer is a great choice for you.
Its easy to see why this is the most popular brewer right now.
The reason why the OXO is my preferred cold brew maker - functionality, and how you can pack it up and down to fit in small spaces. It also has a few other cool, unique features.
The Yama Glass Cold Brew Tower
I would rather spend a day in bed with a Yama glass tower than with my girlfriend.....thats how beautiful this thing is!
Made from carved timber and 4 glass components, it creates cold brew (very slowly) through a unique ice-immersion process that allows you lots of control over your final brew.
Its sexy, its pricey, and it allows you control. These 3 characteristics make it a favourite choice for cafes, and for those who are serious about making the best cold brew of their LIVES.
Read our review before purchasing though, we'll need to show you a few things...
The Hario Mizudashi
In general, if something is made by Hario, I'll buy it. I just trust their brand, and i've never been let down by one of their coffee products.
The Mizudashi is how the Japanese do cold brew, in the most simple form.
Its a glass carafe with an inbuilt filter. Its cheap, it looks good, and it fits in your fridge like a glove.
This is the perfect option for those just getting in to CBC.
