REVIEW: Monster Energy Ultra Peachy Keen

Monster Energy Ultra Peachy Keen Cans

What is Monster Energy Ultra Peachy Keen?

It’s a peach-flavored addition to Monster Energy’s sugar-free Ultra line, which mainly has one-word product names like Gold, Watermelon, Fiesta, Rosa, Paradise, Violet, Red, Blue, and Black.

How is it?

Well, I’m happy to say that Peachy Keen is peachy-keen, jelly bean!

With the previously mentioned Ultra Gold, I felt the pineapple flavor wasn’t strong enough. But that’s not the case with this flavor that has a peachy punch that makes my oral portal perceive it’s packed with peach gummy rings.

I feel as if I’ve used that reference before with another peach-flavored energy drink, but I can’t help it because that’s EXACTLY what this tastes like, except in a liquid form that doesn’t stick to your teeth like gummy rings do.

Monster Energy Ultra Peachy Keen Closeup

I’m enamored with this energy drink so much that I’m a bit sad that I could only find it in 12-ounce slim cans. But I’ve seen images of it in the standard 16-ounce can. If you haven’t had a slim can Monster energy drink, this one has 110 milligrams of caffeine.

Also, although this is a sugar-free energy drink, I can imagine some might find this flavor to be a bit too sweet. I don’t, but others might.

Anything else you need to know?

Monster Energy Ultra Peachy Keen Design

The can’s design has a 60s motif with hippies, peace signs, flowers, smiley faces, and a love wagon. And the copy on the can’s side references the summer of love. Now, I wasn’t born in the 60s, but peachy-keen seems like it’s pre-hippie. Can some groovy person set me straight about that?

The first reference of the term “peachy-keen” happened in the 1950s. But the hippie movement in the US didn’t start until the mid-1960s. I know slang can survive decades because I use “rad” all the time, but was that the case with “peachy-keen”?

Also, I’m surprised this wasn’t called Peace Peach. Although, now that I think about it, I imagine that might cause the opposite of peace with Peace Tea’s peach flavor.


Peachy Keen is a far out tasting addition to Monster’s Ultra line. It’s definitely one of my top three favorite Monster Ultra flavors. If you’re a fan of peach gummy rings and caffeine, this will satisfy your taste buds and bloodstream.

7 thoughts to “REVIEW: Monster Energy Ultra Peachy Keen”

  1. We need more peach flavored drinks in our lives and Monster Ultra is one of my favorites. This sounds like it is right up my alley.

  2. I agreed that the pineapple one wasn’t “pineapply” enough, so this review gives me high hopes for peach. Will look for it tomorrow.

  3. I hate energy drinks, in general, so am most certainly no expert…but I have to ask, are all of them – regardless of brand and/or flavor – the color of bile and/or the color of urine after one has taken a B-complex vitamin? lol Because, yeah…that’s literally what I thought of, when I saw the pic of it in a glass. Icko! Makes me steer clear of those beverages, even more.

    1. A lot of them are clear as the drinks use ingredients that produce a clear beverage. This one, along with most colored drinks, is yellow because of the dyes.

  4. This is definitely one of the best Monster Ultras. Great flavor and no sugar…
    Also Kroger has 6 packs of 16 oz cans of peachy keen for $10. You can also get it in a 24 can variety pack with gold and watermelon at Sam’s Club .
