Iced Drip vs Cold Brew
Author: Bliss Coffee Roasters Date Posted:13 October 2020
Cold drip, ice brew, iced drip, cold brew, kyoto drip, cold extract coffee, Japanese drip, the list goes on. With so many names for these two different brew methods, it’s no wonder people get confused!
What is the difference and what one do I want to drink?
Well, we’ve done the research and hopefully, can make things a little clearer for you!
For the sake of simplicity, we’re going to refer to the two styles as cold brew and iced drip.
The origins of both find themselves in debate. It does seem plausible that cold brew, with is rudimentary design and refreshing quality, originated from Latin America whilst Iced drip stems from the 1600s, while Japan was trading coffee (among other things) with the Dutch.
The two different methods are often confused because they both sound similar, are black, and served cold.
To tell the two apart, we like to think of ice drip as served short like an espresso, maybe over ice too. Cold brew served long like a long black, a full cup. Both are equally as delicious, but let’s explore them a little more!
Cold brew, in its simplest form, is ground coffee steeped in cold water then filtered. Steep times can vary from a few hours right up to a couple of days and depends on the desired result. We use The Bod by Body Brew and love how simple it is to use and the quality it produces. Light, medium, and dark roasts can all be used depending on flavour, but we find that medium-light roasts are best for cold brew – but that’s just a matter of opinion of course! and usually a very coarse grind is used, owing to the long steep time.
The filter can be cloth, paper, or fabric or mesh. The vessel could be anything from a big coffee plunger (French press) or dedicated cold brewer like The Bod, or even a simple bucket and hessian sack!
The end result holds little texture, is very easy to drink and is super refreshing. The flavour can be anything from quite dark and almost tannic to very light, clean and refreshing depending on how it’s brewed and the coffees used. Our favourite and most popular cold brews have usually either been really rounded and fresh, like our the traveller blend, or juicy and big, using a particularly great and different coffee that absolutely jumps out of the iced cup, often from varying seasonal single origins.
Iced drip is far more intricate. The brew tower usually resembles something from a laboratory. Cold or icy cold-water drips at a rate of around one drop per second onto a bed of coffee. It slowly travels in contact with the coffee before passing through a final filter where it drips away into a service jug. Typically, this style will take between three to 12 hours to brew.
Again, different roast levels can be used. Here, the grind setting makes a huge impact on the final brew, affecting on texture and flavour. Typically, iced drip has a port-like texture. It’s a lot more viscous and can be enjoyed chilled over ice or at room temperature, depending on the coffee. It’s far more like a concentrate in that you would typically drink it as a shot or very short drink (30 to 60 millimetres). Because of its intensity and texture, it works great as a base of an iced coffee with milk or coffee cocktail.
For both methods, being brewed without any heat and over such an extended time means the end result is much lower in acid and quite gentle on the stomach compared with other styles. It stores well in the fridge over time and is highly caffeinated.
In terms of operational costs, cold brew is cheap and easy, so much so, that I think every café should serve it. It only requires coffee, water, a filter and a vessel to brew in. Even if you can’t brew it yourself there are plenty of quality re-sellers available, making the process as easy as selling soft drink or bottled juice.
Ice drip on the other hand requires a far more elaborate system to brew, and needs to be maintained the whole time, but the brew apparatus makes for a great talking point!
For the team here at Bliss, both styles are thoroughly delicious with neither better than the other. We tend to enjoy cold brew like iced tea and iced drip like a delicious espresso on a hot day. If you’re at the beach or having a barbeque and want something refreshing - cold brew every time. If you’re trying to get work done, iced drip is the way to go on a hot day!
We’d encourage you to try a range of different expressions of both (or brew your own) until you find what’s great for you.
