What is the best type of coffee to use for cold-brew coffee?
Q : Hi. Could do with knowing what-Grind: coarse or thin
-Roast: Dark or Light
-Variety: Robusta, Arabica, etc..
makes the best coffee for cold-brewing.
I am currently using Cafe Bustelo "Espresso" Coffee.
It is is OK, but not a patch on Illy and other brands I have used before.
Is there an "off-the-shelf" brand that is particularly good for this?
A : thin, dark, french roast
eight o clock is excellent
When cold brewing coffee, how long are you suppose to let is soak/brew?
Q : I heard your suppose to let it sit for at least 12 hours. But can I let sit for, let say, 4 hours?
A : It should set for between 10-16 hours (depending on preference). I do it between 12-14 hours in the fridge.
It won't extract very much flavor in only 4 hours. You could do it, but you won't be able to dilute it as much, so the concentrate won't last as long.
How long can I store brewed coffee (cold)?
Q : I'm a college student living in a dorm right now, so brewing coffee fresh daily is a really big hassle. Recently, I've just been buying energy drinks to wake up in the morning, but that adds up and not only is it expensive, it just doesn't taste right in the morning.
At home, I like to make iced coffee by brewing it hot through a french press and then just letting it cool and placing it in the fridge overnight (I know, cold brewing is suppose to be less bitter but I'm not patient enough to wait that long).
What I'm wondering is, how long can my cold coffee store for in the fridge before going bad/tasting weird? I'd like to brew the least amount possible since I'm in a dorm without a kitchen.
Thank for the input!
A : You should use an airtight container. Brewed coffee in sealed containers (oxygen free) can last almost indefinitely. Coffee deteriorates when exposed to oxygen.
Does cold brewed coffee have more or less caffeine than hot brew?
Q : I need a scientific answer not hearsay or unfounded most often web search answers.
I need a scientific answer not hearsay or unfounded most often web search hit answers.
A : Extraction processes are generally more effective at higher temperatures. Exceptions include the extraction of substances that are less soluble at higher temperatures, such as carbonates, which represent a minority. Caffeine is typical, in that it extracts better at a higher temperature, because it is more soluble at a higher temperature.
Other exceptions to the rule include substances that decompose or react at higher temperatures. Caffeine is stable all the way up to its sublimation point, which is higher than the boiling point of water. It will neither sublimate nor decompose so long as there is still any water left.
Therefore, hot brewed coffee will have more caffeine than coffee brewed cold. Once it's brewed, storage temperature won't matter, unless the water evaporates significantly, changing its concentration.
