While you might crave a steaming cup of coffee on those cold winter mornings, on a scorching summer afternoon, you need a cold, refreshing brew. This is when the icy cold brew steps up to offer you a glass full of flavor. However, making this brew correctly at home requires you to have the best coffee grinder for cold brew.
A cold brew perfectly highlights the true flavors of the coffee beans because the long brew time fully extracts the coffee flavors. To be sure you are getting the proper taste, it is important to grind your beans fresh at home with a proper coffee grinder.
If you buy pre-ground coffee beans or if you grind the beans up incorrectly, you could end up with a bitter-tasting brew. There is nothing worse than waiting 24 hours for your brew only to end up with bad coffee!. This lengthy brewing time fully extracts the oils from the coffee; if some grounds are too small, they will over-extract and ruin the whole brew.
The trick is to use a high-quality coffee grinder to ensure a consistent bean size. The best grinder for cold brew coffee is one that evenly and coarsely grinds the coffee beans. You can choose between manual or automatic, and with so many options on the market, it can be hard to find the right one. Read on to discover the right grinder for your needs.
In a nutshell, the best grinder for your cold brew is the OXO Brew Conical Burr Coffee Grinder. This grinder is so simple to use with a one-touch button and has over 15 grind settings. The grounds container is also large enough to produce enough grounds for a large batch of coffee.

Choosing the Best Coffee Grinder for Cold Brew
Grind Size Settings
When choosing a coffee grinder, one of the first features you should consider is the grind size settings. This will help you decide what grinder will be best for your preferred brewing method. In this case, you want a grinder that can keep the beans quite coarse to prevent the over-extraction of oils and flavors.
If you are not only going to make cold brew coffee, you should look for a grinder with multiple grind settings to switch between fine and coarse grinds as you need to. Luckily, most grinders offer a wide range of grind settings to give you this freedom.
Choose a Burr Grinder
As you begin your search for a coffee bean grinder, you will notice there are two main variations: the burr grinder and the blade grinder. This can be confusing if you are new to grinders, and due to the cheaper price tags on the blade grinders, you may be tempted to choose one of those.
However, blade grinders are not the best for creating a consistent grind for your beans. The blades spin around in the chamber, and some beans may elude the blades, resulting in an uneven grind. This will lead to bitter or sour coffee.
Burr grinders, on the other hand, force all the beans through the tight burrs, ensuring each bean is crushed at the same level, producing a consistent grind to allow an even extraction of flavors when brewing.
Manual or Automatic
Another factor when choosing the right grinder for your brewing is whether it is manual or automatic. This one comes down to preference as well as space and traveling needs. The automatic grinders are faster and easier to use by simply pressing a few buttons, but they will take up more counter space and use more electricity.
The manual grinders require more effort on your part when manually grinding the beans, yet they are smaller and lightweight. This means they can easily be placed in your carry-on and move with you when you travel or when you go camping. They are also much cheaper and quieter than the electric variations.
Bean and Grounds Capacity
Coffee grinders offer different bean hopper sizes and grounds container sizes. This can also sway your decision depending on how much coffee you would like to grind at a time. Electric grinders usually have larger containers, so you can grind up a large amount at a time.
When brewing a cold brew, you will most likely do large batches at a time due to the long time it takes to brew. You will then need a larger hopper and grounds container if you want to save some time when grinding.
Why do you need a coffee bean grinder for cold brew?
Coffee beans start to oxidize and lose their flavors as soon as they are ground. This means you should be grinding your beans at home right before you brew your coffee. Since a cold brew has a very long brew time, you want to ensure you keep the flavor of the coffee beans right up until brewing.
What is the best grind size for a cold brew?
Cold-brewed coffee is perfect for highlighting the bold flavors of the coffee beans, and this requires a coarse grind size. The larger surface of the coffee beans allows you to fully extract these flavors throughout the brewing time.
This also prevents an over-extraction of the oils from the coffee and prevents the beans from overheating, which may occur with longer grind cycles.
What beans are best for a cold brew?
There are several quality coffee beans for a cold brew, and if you enjoy the beans in your hot brew, you will likely enjoy them cold too. However, light to medium roasts really shine with this method because the subtle flavors come through during the long brew time. A dark roast may become too bitter and heavy with this method.
If you have your beans and your grinder ready, all you need is a quality cold brew coffee maker, and you are all set to start brewing your delicious summer beverage.
