In this article, I will cover everything there is to know about barrel aged coffee. This is a new coffee trend that is slowly rolling out at the moment and is definitely a nice coffee trend for you to try.

Barrel aged coffee is coffee that has been aged in retired liquor barrels like whiskey, bourbon, and rum barrels. The coffee beans are aged in the barrels for up to a few weeks at a time, slowly developing more flavor.

Does that sound good? For me it does. I have had the opportunity to try a great whiskey barrel aged cold brew coffee and it blew my expectations. Read along to find my story on this amazing experience I had in Milan.

How does the aging of the coffee beans work?

Before I get into detail about how the aging of coffee beans work, what is barrel aged coffee? As I have mentioned before, barrel aged coffee is coffee that has been aged in retired liquor barrels. This is where the coffee beans get all of their unique flavors from.

The coffee beans that are aged in the barrels are the green coffee beans that are yet to be roasted. The green coffee beans are added to a retired liquor barrel and then left in there for a while, most of the time for at least 2 to 3 weeks.

While inside the barrel, the green coffee beans take in all the flavor that is left in the wooden barrels. This is where all the flavor characteristics are developed. There are even some coffee roasters out there that age their coffee beans for an even longer period of time. A longer aged coffee bean is still something I would love to try.

After the coffee beans have aged, they are off to be roasted. Most of the time, the coffee beans are roasted to a medium roast. This way, all the delicious will be kept inside the coffee beans.

I have seen some barrel aged coffee beans that have been lightly roasted, like a blond roast. This will keep even more flavor inside the coffee bean and if you have been drinking coffee for a while, you might even notice the origin of the coffee bean by drinking it.

Which coffees can I brew with the barrel aged coffee beans?

If you want to use barrel aged coffee, you will be able to make every coffee that you like. I have tried both the hot and the cold brew versions of barrel aged coffee beans, and I prefer a cold brew version when a barrel aged coffee bean is used.

While brewing a cold brew coffee with barrel aged coffee beans, you will smell the amazing flavors from the moment you open the bag. The smell that comes out of the coffee bean bag is amazing.

Once you start grinding your coffee beans, most flavors are circling in the house, and you will be happy that you’ve bought a bag of these delicious coffee beans.

To get back to the different kinds of coffees you can brew with a barrel aged coffee, I suggest starting with a batch of cold brew coffee. Brewing a batch of cold brew coffee will expand your coffee palate and will give you an idea of what the coffee will taste like when you make a hot version.

For me, the hot version of coffee made with barrel aged coffee is a waste of these beautiful coffee beans. The flavors you smell when brewing coffee are quickly lost and are nowhere to be found when taking the first sip of coffee. So, I would suggest sticking with a good cup of cold brew coffee instead.

The fun part about brewing coffee at home is that you can switch it up however you like. To make Your Dream Coffee at home, it’s all about experimenting with coffee and finding out what you like.

Cold brew whiskey barrel aged coffee from Starbucks

Last month I was on a city trip to Milan when I stumbled upon the most amazing Starbucks shop that I have ever been in. The Starbucks Reserve in Milan.

When I entered the Starbucks, I expected it to be just another Starbucks, but it was actually the opposite. It was the biggest Starbucks that I had ever seen. There were people roasting coffee beans in a big coffee roaster. When the coffee beans were done roasting, a machine shot them through metal pipes that went straight to the coffee bar.

Of course, like any other Starbucks, there was a lot of choice in coffee drinks. What immediately caught my eye was the cold brew whiskey barrel aged coffee. It was the first thing that I ordered.

The experience was amazing. The cold brew coffee was served in a “decanter,” and there was a whiskey glass with a nice block of ice in it. It really did look like you were going to drink whisky at that moment.

My first sip of the coffee was really intense, but it was the most amazing cold brew coffee that I have ever had the pleasure of drinking.

The coffee taste was really full and rich, and there were many fruity notes in there as well. But the slight whiskey after-taste was the best of the whole coffee.

I bought a bag of whiskey barrel aged coffee beans to take back home, which has served its purpose. I have a few coffee beans left over for one more cold brew batch. At the time of writing this article, I have the bag of barrel aged coffee beans sitting next to me. The flavor that is circling in the air is amazing.

If you are in the area, I suggest popping by the store and giving the coffee a try as well. The Starbucks Reserve’s whole experience was pretty special, and I think you will enjoy it as much as I did.

Which coffee beans are used in the aging process?

The variety of coffee beans depends on the coffee roaster, and the coffee beans can come from anywhere around the world. You can say that every coffee bean can be aged, as it will develop even more flavor from the aging followed by the normal roasting process.

Although this technique is not widely known yet, I think this will be the next popular thing that people will ask for. The flavor profile that the coffee beans will develop is something exceptional.

The coffee beans from the Starbucks Reserve in Milan are from Guatemala and are medium roasted. The information about the coffee beans are explained by a card that is attached to the coffee bean bag, check it out:

After I went to Milan and brought back a nice bag of barrel aged coffee beans, the regular roasted coffee beans taste kind of flat now. Using barrel aged coffee beans to brew your favorite coffee is the best thing that happened to coffee in while.
