The taste and ability to wake someone up has been regarded as the prime benefits, and it is also linked to increasing energy levels. Most people are uncertain whether to use cold or hot water when preparing coffee. There are several benefits accrued as a result if using cold water for the preparation of coffee. For instance, cold water is highly recommended to facilitate the preparation of a delicious cup of coffee when it comes to Turkish coffee. Coffee is first brewed in cold water to enable the coffee particles to have sufficient time to soak in the water and release the flavor.

Turkish coffee or Mocha aims to produce as much foam as possible to enhance its delectable taste. Cold water is preferred because it ensures the maximum oxygen content in the water, potentially creating more froth.

You then boil the coffee, and the froth, in turn, rises, which must be quickly removed from the heat to prevent boiling over. The initial cold water enables optimum extraction of coffee. In recent years, cold brew coffee has gained popularity among most users.

Cold brew coffee is dependent on the time when drawing out the caffeine and flavor of coffee beans. These coffee beans are steeped in cold water for hours to ensure optimum extraction of the caffeine and sweet taste.

This method of extraction makes the coffee less bitter as compared to hot water. Water temp is important for Cold brew coffee and if you have not tried a cup give it a try as the taste is unique. An important reason as to why people prefer cold water is simply because it is much easier to prepare. All you need to do is efficiently mix the ground coffee beans with water and steep them for around hours.

You then strain and dilute the concentrate with water at a specific ratio, preferably So if the water in the reservoir is cold it takes longer for the element to heat it and send it up the tube. If the water in the reservoir is warmer it heats it faster and burps it up the tube at a higher rate. No rocket science here. Its very much the same way an old percolator worked back in the day. I was thinking as you described it that it is a percolator. Hopefully it is not letting the water boil right before applying it to the coffee, as water at that high of a temperature will affect the flavor of the coffee.

Thanks for the comment! Comment by Marc Wortman — January 17, pm. I also once forgot to put coffee into our drip machine. I dumped the hot water back into the reservoir and found out that my 2 filter set-up could not keep up with the accelerated flow coming from the heater and check valve. Allow me to say, an unattended coffeemaker that overflows from the top of the filter basket makes a remarkable mess.

I was once experimenting with putting cinnamon directly in the filter with ground coffee. Too much cinnamon will clog the filter. Imagine the mess you made, but combined with ground coffee that overflowed with the water.

Calcium bicarbonate is in equilibrium with calcium carbonate limescale , and hence there is a shift for insoluble calcium carbonate to form soluble calcium bicarbonate. Taste: As I think has been mentioned, in the old days hot water supply was not drinkable and there was lead in it, etc. Hot water is also un-filtered, and is capable of dissolving far more impurities than cold water. There is also the point that some people say oxygen activates flavours in the beans.

If this is the case, cold water has far more dissolved oxygen than hot, and would therefore have a better ability to do so. Excellent information, Stephen, and important additions to the original article. Thank you for sharing this! Comment by Marc Wortman — March 25, am. What I see here is that all old style percolators and new drip coffee makers are governed by the warming plate.

We all agree that both have a tube with water in it and that both have bubbles that push water through that tube. The bubbles are caused by the water reaching a temperature of boiling at the warming plate however, the water in the tube cools it as those bubbles rise. The length of the tube is designed for the temperature the manufacturer wants the coffee to be brewed at.

The drip makers, with thermostats, you can hear them make a noise when they turn on again only keep the coffee in pot warm. Now I use one of those wire screen permanent basket filters but drip makers are designed to use paper filters of different shapes which keeps the coffee in contact with the coffee for a designed amount of time.

Think on this for a moment… The trail cook for all those cattle drives years ago just threw coffee in a pot with water and boiled it, poured it in your tin coffee mug cup and you drank it grounds and all. Good luck to you all, Don W. Good luck and thank you for this insight, Don. With all of the advances made in coffee brewing, it would be quite an experience to try the coffee once served on those cattle drives. Not necessarily a flavorful experience, but an experience nonetheless.

There is no taste difference. Comment by Peter Hahn — December 29, pm. Regarding the mineral content of hot water; assuming a standard type hot water heater it is actually less than cold water because of settling in the hot water tank.

This is also why household hot water pipes will freeze faster than cold water pipes; the higher mineral content of the cold water helps hold more energy and delays freezing. Obviously other factors can come into play and affect the consistency. I learned this working with a group of advanced engineers on a project in which the question was relevant to the success of our experiment.

The engineers discussed and tried many of the various hypothesis offered by science but the experiment results remained inconsistent. The design group finally called in the head engineer who then called his plumber who offered the above explanation. The experiment was a success and led to development procedures for a successful new product line. As far as the comments on water softening systems go, there are some houses plumbed to soften the hot side only but it has never been the desirable way to do it.

In the early days of water softeners it was proper to set up to exclude the kitchen faucet and exterior hose bibs so the sodium chloride did not have a detrimental affect on plants and lawns but a long time ago they switched to using potassium chloride to treat the whole house with water safe for for all use.

Comment by Marc Wortman — May 10, pm. It simply amazes me how quickly typing starts, and thinking stops on the www. Within reason. What does matter is the steep time and temperature of the water in contact with the coffee grounds. Alllllllllll the Mr. Coffee makers work on the same principle. They do have a thermostat, which turns on the heating element. At boiling point, the water will rise up the tube and drip over the coffee in the basket.

The cold water takes longer to heat to boiling than hot water. Thus running the brew cycle longer or shorter. If the brew cycle is too short, due to using hot water, the basket will certainly overflow. The coldest water gives the longest brew cycle. Longest steep time. And strongest coffee. Given the same amount of grounds. Control the process to control the outcome.
