Gift Lab: Can You Do Cold Brew Coffee at Home?

September 22, 2016

Randy and Cold Brew

Abstract:

Coffee is good. Hot coffee when it’s still hot out is not so good. Will the Cold Brew Coffee Maker save me?

Background:

I am one of about 2/3 of adult Americans who will have a cup of coffee today at work. But in the dog days of summer, hot drinks aren’t really what I’m thirsting for. Unfortunately, every time I’ve tried to make iced coffee it came out bitter. It usually just sits in my fridge as a testament to my failure for a few days before I toss it.

Maybe I’ve just found 1,000 ways not to make iced coffee.

With that in mind, I set off with the Cold Brew Coffee Maker to try one more time.

Before I picked up this coffee maker I had no idea what “cold brew” meant. As I learned from the instructions, it’s a method of brewing where cold water is slowly percolated over ground coffee. The cold water prevents the bitterness of the beans from flowing into the retaining jar, and the slow pace allows plenty of flavor to end up in the final product. It takes a while, and the longer you allow it to take, the more flavor will end up in your cup.

Hypothesis:

My null hypothesis: I can’t make a decent cup of iced coffee.

My alternative hypothesis: I can (if I use the right tools).

Gift Lab: How to Stay Cool & Caffeinated with Cold Brew Coffee

May 15, 2015

Abi tests the Cold Brew Coffee Set

Product: Coffee Cold Brew Gift Set

Hypothesis:
Iced coffee is one of my favorite morning treats, so I was super excited to try out the Cold Brew Coffee Gift Set (and drink the coffee in the morning at work). I hypothesized that this set would be a great alternative to spending money at coffee shops.

Research:

The set includes instructions, which I followed to the best of my ability. I am rather impatient, so there were parts that I was tempted to skip, but I stayed faithful to the directions throughout.

Experiment: 
I began by boiling the filter (the instructions say to boil the filter before its first use, to pre-shrink it) in water for 10 minutes. The instructions say that filters “will continue to shrink slightly for the next few uses and will produce the best quality brew from then on.” I don’t have any proof of this yet, but I look forward to tasting all the future cold brew coffee batches to see if taste improves over time.

Boiling the Filter

The provided recipe says to use 2 cups of freshly ground coffee of your choice (the kit comes with two cups ready to go for your first batch).

Coffee Beans

I added the coffee to the fabric filter and “bloomed” the grounds, as per the directions. In this case, to bloom the grounds means to wet them thoroughly and let them stand for 60 seconds.

Grounds

I twisted the neck of the filter, as tightly as I could, and wrapped the tie string around the neck a few times, then slipped the neck of the filter through the glass ring (which is attached to/hanging from the filter bag).

Tightening Filter

Then I inserted the filter into the jar and filled the jar with cold water.

Cold Brew Coffee In The Works!

Luckily I did this at the end of the day in the office, because it takes 12-16 hours to cold brew in the fridge till it’s ready. The next morning, I would get to sample my first batch of cold brew!

Conclusion: 
Fresh Coffee | UncommonGoods

Ta da! I opened the fridge to find some actual cold brewed coffee. It looked pretty good, smelled delightful, and was also tasty. I did feel that it was a little weak, though. I removed the filter, dumped the grounds into the compost bin, washed the filter out, and set it out to dry until I made my next batch.

Finished Coffee

The kit comes with a pouring device that fits inside the lid, which works quite nicely for pouring the coffee once its done.

Drinking Cold Brew Coffee

People don’t naturally look at a camera when they are drinking coffee, but I wanted to show you that I was trying the coffee I just made, and allow you to fully see the expression on my face while I first tasted it. I look pretty strange, but I assure you, the coffee tasted good and I was excited to be trying it out.

Yumzies! |Delicious Iced Coffee with Coconut Milk
Here I am, showing off the final product, in my favorite glass, complete with almond/coconut milk. So yummy!

In case you are wondering (and you really might be curious about this), I do not add sugar to my coffee, unless it tastes completely awful. I did not even consider adding sugar to this batch. I found it very yummy (though, like I said, I would have liked it to be a bit more concentrated).

During my next trial, I filled the filter as much as possible (this was probably almost 3 cups of coffee grounds). It was delicious but quite strong. I think two and half cups is probably the ideal amount of coffee grounds that should be used for this cold brew coffee (at least for it to be just right for me). I’m excited to use the Coffee Cold Brew Set this summer to beat the heat in a very delicious way!
