This week I am taking a question from Lantz who’s asking about caffeine in his favorite coffee.


How much caffeine is in Kirkland brand coffee?

by Lantz from Minnesota


I’ve been buying Kirkland coffee for a while, and I was wondering: How much caffeine is in this Kirkland brand of coffee? Thank you.


Thank you for taking the time to contact me. I can only surmise that you’re worried if you’re consuming too much caffeine.

While Kirkland doesn’t publish its caffeine content figures anywhere, it is reasonable to assume that their caffeine content is fairly standard, with a possible exception for the espresso. I believe that you’d be looking at about 150-200 mg of caffeine per 8oz cup. There are a lot of coffees with more caffeine than that, such Panera’s Frozen Mocha, Dunkin Donuts with Turbo shot, etc.

However, … a straightforward number may be more elusive than that. Why? How much ground coffee do you put into each cup? I usually use between 1/2 oz to 1 oz per cup, but then my cups are a little bigger.

Also, how big is your drink serving? A standard Americano (Tall size) has about 80z of coffee in it, and approx. 150mg of caffeine. But a Venti is double that, so the total caffeine is 300mg which is quite high.

Lastly, if you’re drinking Robusta coffee (either mixed or pure), you’ll likely find that the coffee has even more per oz of caffeine. Robusta is often mixed with better Arabica in espresso coffees, but you can also find it in Vietnamese coffee, and many cheaper (non-100% Arabica) coffee.

I’ve found several useful resources for caffeine in coffee:

Do you prefer a lot or a little caffeine in your coffee?

If you’re looking to cut down on your caffeine content, you should also look at the amount of soda, tea, sports drinks, and chocolate you consume each day. Then decide where to start by looking at what causes the problems. Is it too much of one or too much of all?

If it’s too much caffeine in coffee, I’d suggest mixing your coffee roasts: 50% caffeinated with 50% decaffeinated. You’ll need to mix the same roasts/beans, so you don’t get any weird flavors! Or look for some half/half coffee. It’s a good way to cut down on the volume of caffeine in your coffee.

Also, substitute better coffee for volume; so if you cut down, at least you’re not suffering from complete abstenance. Quality can make up for lack of quantity.

Lastly, you should note that there are quiet a few varieties of Kirkland coffee, but I’d expect the Hawaiian, Jamaican and South American varieties to be a little higher in their caffeine levels, while Sumatra and Arabica-based Espresso to be moderate or lower. Longer roasting times tend to reduce caffeine levels.

You can also check out these low caffeine coffees at Amazon if caffeine is a concern for you.

Hope that answers your question, Lantz.

Best Wishes
