Running Coffee Through Twice

Can You Run Coffee Through Twice?

If you want a quality cup of coffee, never reuse grounds to brew more than once. If you immediately reuse grounded beans after brewing a cup, your coffee will end up tasting bitter and unsavory. On the other hand, if you let the grounds dry before brewing again, the coffee will be extremely sour and positively foul to drink.

If you are re-brewing with ground coffee a second time, you cannot extract the 50% extra caffeine. Even with that amount, using the grounds from the coffee is not really a big deal, as there is already way too much caffeine and flavor extracted from a second batch.

Essentially, you are getting at least double the amount of caffeine because you are doubling either the amount of ground coffee or the total coffee amount (using the coffee that is already been brewed, not water). If you want an extra-strong cup of coffee, make three cups of coffee using exactly the same amount of ground coffee, and then wait for the third cup to finish cooking. You can make one larger cup of coffee using the same amount of beans, or you can extend your steeping time. As a practical aside, you might even want to think about just making a larger batch of coffee in one sitting.

If you are wondering whether or not you can do exactly the same brew method for your coffee two times — once with new grounds, the second time with ones that you already used — yeah, you can. The aim of brewing double, regardless of whether you decide to double-brew or to use twice as much grounds, is still a stronger coffee – but there are some caveats. The goal from double brewing, whether you choose to blend twice or to use double the grounds is still stronger coffee – but there are a few catches. Here are some things you will want to avoid to ensure that you can have an excellent double-brew, without destroying your coffeemaker.

Let us get one thing out of the way first; if you are serious about flavor profiles and ratios in your coffee, you may not want to re-use the grounds. If you really do choose to brew a different coffee using your reused grounds, you could wind up with an almost decaffeinated coffee. That is, by trying to repurpose used coffee grounds, you are also extracting some slow-dissolving compounds, which are of no use in the cup, since they ruin the flavour. Reusing coffee grounds drained out flavour, and you barely got the flavor and aroma that you would expect in a good cup of coffee, which is why it is recommended that coffee grounds should never be used more than twice.

If you reuse coffee grounds right away, you are going to end up with a bitter, over-extracted mess, whereas if you allow the grounds to dry out first, instead, you are going to get a bitter, underwhelming cup. If you choose to run your coffee grounds through the extraction process for the second time, the beans used would already lost some of their soluble components from their first extraction. You could try to achieve better results by steeping the grounds longer, but in general, the major compounds that make for a balanced cup of coffee are already dissolving from the first extraction. Using re-used coffee grounds right away will make sure that you are able to get a better-than-extracted coffee for your second cup.

A brewed coffee cup is not going to extract nearly as much as a warm cup of water, so you are likely going to want to use finer grounds for your second pour-over. Your brewed coffee will have bitter flavors if the water is too hot or strong, though definitely with much stronger flavors.

The ideal cup of coffee must be brewed exactly the right way, because under-brewing or over-brewing will ultimately result in an unpleasantly tasting cup of coffee, that is too acidic or too bitter. Over-extracting can leave you with bitter cups, whereas under-extracting results in a weak, acidic, pale cup of coffee. The most nuanced answer is that, for various circumstances, double-brewing coffee results in a coffee that is not only less flavorful than the first batch, but will contain less caffeine.

In all honesty, if you do not want to bother with extra cleanup, burnt flavors, or any strange flavors in your future cups of coffee, simply double up on coffee when brewing, or use something like a French press, where you will not need to worry about spoiling your next persons cup.

Brewing is generally pretty simple: Just use double the amount of grounds (24-30 grams rather than 12-15 grams per serving) and your coffee automatically gets stronger. The way to do it is, brew the coffee first in your drip machine, and then add your brewed coffee in the French Press with extra grounds, it will give you optimum flavour. It may sound like leaving your grounds to dry would solve over-extracting, but when your coffee is drying, coffee is going to keep leaking out, and by the time it is fully dried, nearly all the flavour is gone.

This is because percolators typically put more heat on the grounds than in other methods, and they can also recycle already-brewed coffee back into the beans. Truthfully, it is probably the least-true myth of them all: Percolated coffee is notoriously powerful, mostly due to the cyclical nature of the brewing process (giving grounds more time to steep) and the warm temperatures of percolated water. One of the biggest conundrums with percolated vs. brewed is that there are sometimes really tiny bits of coffee grounds left behind in a single-brew that are not fully percolated out (just look down the bottom of your cup of coffee after finishing a sip, and you will know what I mean).

You may be under the impression that double brewing is just passing coffee through your coffee maker one more time, but it is just not. Percolators are easily portable from one location to another, and really, all you need to make coffee with percolators is the machine itself, your grounds (ideally coarsely ground, to prevent them sliding through holes in the metal basket), clean water, and some way of heating the water, such as a campfire.

Can coffee be filtered twice?

Due to a longer extraction time, using two coffee filters can produce coffee that is stronger and bolder. However, we do not suggest brewing coffee with two filters. You risk damaging your automatic coffee maker in addition to brewing a cup of bitter, over-extracted coffee.

Can you run espresso through twice?

Both yes and no. Except for drinking another shot of espresso, the coffee you get after your espresso is excellent for many things. Coffee powder cannot be used more than once, in contrast to tea, which can be used again for a subsequent, weaker brew. The only flavorful brew is the initial extraction.

Can I Rebrew coffee grounds?

Whether you use a coffee machine, French press, or Bulletproof Original Coffee Pods in a drip brewer, recycling coffee grounds will make your next cup of coffee taste like water with a bit of coffee flavour. A superb cup of coffee can only be made using freshly ground coffee.
