Reviews mention

  • Lactose-free formula, digestive-friendly
  • High protein content, efficient macros
  • Creamy texture, easy drinking
  • Clean ingredients, stevia-sweetened
  • Stevia aftertaste, artificial sweetness
  • Inconsistent flavors, uneven taste
  • Occasional chalky, watery finish
  • Canned, chemical-tasting notes

Slate earns mixed-to-positive reviews: it delivers high protein and lactose-free, “clean” ingredients with a smooth, creamy texture and reliable caffeine lift, but flavor polarizes—stevia and artificial notes, canned/chemical aftertaste, and weak or chalky finishes appear in several flavors. Reviews praise classics like Dark or Milk Chocolate, Vanilla Latte, Caramel Latte, and Mocha for easy daily protein, yet vanilla and some strawberry iterations underwhelm, and coffee variants vary in realism; buyers seeking taste-first may prefer alternatives, while those prioritizing macros and lactose-free convenience appreciate Slate.

  • i wanted to like it, but i can’t get past the stevia taste. The ingredients are pretty clean, so I give them credit there. The protein and caffeine content are also decent. But the taste on this specific flavor just…isn’t very good. I don’t really get any caramel flavor, just a weird unpleasant sweetness. definitely not something i’d buy again. I imagine SOME people may enjoy this so I’m not gonna rate it lower, not for me though.

  • Overall, this brand is decent. There are other protein drink products that I find tastier than this. The strawberry flavor is only just OK compared to their others. The calorie to protein ratio is great and better than a lot of other products.

  • Horrible experience!!! I ordered a case for $112.00 and they refused to refund or replace just had the nerve to offer me 15% discount to spend more money!!!!

  • Terrible drink very watery and bottom half was chalky. I read all the great reviews, thats why i got it. Going thru cancer treatment on high calorie diet. There must be alot of people who never heard the word Ensure.

  • As a big coffee drinker who has been trying to increase the amount of protein intake daily this product is really great. I find the flavor delicious and the fact that it is low sugar. It is really great.

  • It's less sweet and creamy than classic vanilla. High protein and caffeine · Creamy and delicious · Love these drinks · Loved the taste!!!! · Amazing! · I loved the taste. I would purchase again and recommend it.

  • It’s the weakest grossest coffee type drink I’ve ever had, lucky I didn’t pay for it. I’d dump it out but I want to see if it atleast has the caffeine push to it as I’ve got to mow the lawn after watching the football game today. But I’ll be just gagging this stuff down, wish I have something to eat with it to cover the terrible flavor.

  • I mostly like Slate drinks. They're nice for a sweet treat and I like the coffee flavors, but the artificial sugars are pretty obvious tasting in the drink. It's ok if you're wanting a sweet treat that isn't too many calories but don't expect it to taste like the real thing.

  • I am in love with their milkshakes and use them as a base for my Ninja Creami all the time. The Vanilla is my favorite but I like the classic chocolate as well. The drink is a great way to get a high amount of protein in without all the added sugar or artificial flavors or sweaters other shake brands offer. Not to mention they taste great too.

  • I think this brand is good if you are looking to get protein easily in a can, but the taste isn't my favorite. The vanilla and mocha are just alright, but the caramel is better tasting to me. The classic chocolate one is decent as well. Overall I wouldn't choose these for their taste.

  • Taste isn't my favorite, but I like these because they're lactose free. For some reason you can taste that it's from a can in the milk. I think the coffee ones are the ones where you can least taste this. I However, the protein ratio to calories is pretty good. They recently came out with a strawberry flavor in Sprouts so I decided to give these another try, but there's still like an off taste along with it. Also I wish the strawberry taste was stronger.

  • WOW! I am pleasantly surprised, it is SO GOOD! It doesn’t taste exactly like chocolate milk but oh my god, it tastes good and is a great alternative especially for those that are lactose free!

  • As a person who is lactose intolerant, it was tough to find a product suitable for the digestive system. I came across Slate milk randomly in the supermarket. I got to tell you, I love this product. This product is suitable for those who are lactose intolerant in packs nutritional value offering 20 g of protein. With me being in the medical field, slate milk offers me 175 mg of caffeine, which keeps me going to help save lives.

  • Not sure what I was expecting, but this protein drink was underwhelming. It basically tastes like canned milk and has a strange chalkiness that I can’t get out of my mouth after drinking it. It’s not something I’d buy again, but if you are lactose intolerant this may be a product you’d like. I wouldn’t recommend this flavor as it’s pretty bland. On the positive side, it packs 20 grams of protein with hardly any sugar or carbs.

  • This brand is one of my favorite coffee protein drinks. It’s one of the cleaner brands. They use stevia instead of sucralose and erythritol which is a big win for me. I get excited to drink these in the morning when I have them chilled and you hear a nice pop when you open it. I have tried most of the flavors except for the sweet cream latte which sounds like the best tbh but it’s been hard for me to find it in stock. The caramel latte and the classic chocolate are my favorite so far. The mocha latte is not bad I just prefer the chocolate milk flavor of the classic chocolate. I never really favorited mocha lattes in general. I would have to place the vanilla latte dead last. The flavor for the vanilla latte was not what I was expecting and has a super weird artificial flavor compared to the others.

  • I really like the slate mocha latte one. I have tried the vanilla and caramel latte ones. I’m not really a fan of those flavors. But I will still drank those flavors. I really like that it doesn’t go over the daily limit of 200 mg and I like that it has 20 grams of protein in it. I think people that are coffee lovers would love this drank.

  • I tried this on a whim after being frustrated with the chalky, thick, protein shakes that make me want to vomit a little (huel, rebl(?) i’m looking at you…), and the texture of this one was a delight. Easy to drink, tasty and not too thick, but it could use some more protein. Overall, one of my favorite protein drinks thus far.

  • this tastes sort of chemically. it doesn't taste like coffee to me. I will probably only drink half of it. It might be good mixed up in a smoothie but it's not good by itself at all

  • I was disappointed to taste some very artificial sugar in my Slate milk. I liked that it was high protein and dairy free, but personally could not get over the flavor.
