By Miles Schwartz, Founder of Bare Brew. Disclosure: we make one of the drinks in this table. Its numbers come off its label, same standard as the rest.
Most "best Bang alternative" pages are flavor rankings. If you drink Bang, flavor is probably not why you are switching — 300 mg of caffeine in a 16 fl oz can is the product. So we compared the small set of drinks that actually play in that class, on labels, ingredient lists, and price. Every figure below was re-read off a published nutrition panel or ingredient list on October 27, 2026, and where a panel does not state something, this page says so instead of filling the gap.
The labels, re-checked October 27, 2026
Energy drink formulations vary by flavor, so each row names the flavor whose panel we read.
| Drink | Size | Caffeine | Sugar | Calories | Sweeteners |
|---|---|---|---|---|---|
| Bang Energy (Power Punch) | 16 fl oz | 300 mg | 0 g | Not stated on the panel we read (total carbohydrate 0 g, total sugars 0 g) | Sucralose + acesulfame potassium |
| Reign Total Body Fuel (Melon Mania) | 16 fl oz | 300 mg | 0 g | 10 | Sucralose + acesulfame potassium |
| Celsius, core line (Raspberry Acai Green Tea) | 12 fl oz | 200 mg | 0 g | 10 | Sucralose only |
| Alani Nu Energy (Cherry Slush) | 12 fl oz | 200 mg | 0 g | 10 on the panel; brand copy says "15 calories or less" | Sucralose + acesulfame potassium |
| Bare Brew Cold Brew | 12 fl oz | 320 mg | 0 g | 20 | None |
Bang and Reign are the only true like-for-like caffeine matches — both 300 mg, both 16 fl oz, both zero sugar. Celsius and Alani are a step down in dose (200 mg) in a smaller can. Bare Brew is the only coffee-based entry: 320 mg per can, and the 20 calories come from 5 g of total carbohydrate in black coffee, not from anything added. It is a low-calorie can, not a zero-calorie one, and the label says so.
Caffeine per fluid ounce: the number the big cans hide
A 16 fl oz can makes 300 mg look different from a 12 fl oz can. Divide it out — this is arithmetic on the published serving figures, not a new label claim:
| Drink | Caffeine | Size | Caffeine per fl oz |
|---|---|---|---|
| Bare Brew Cold Brew | 320 mg | 12 fl oz | ~26.7 mg/fl oz |
| Bang Energy | 300 mg | 16 fl oz | ~18.8 mg/fl oz |
| Reign Total Body Fuel | 300 mg | 16 fl oz | ~18.8 mg/fl oz |
| Celsius, core line | 200 mg | 12 fl oz | ~16.7 mg/fl oz |
| Alani Nu Energy | 200 mg | 12 fl oz | ~16.7 mg/fl oz |
Scope that properly: this is a comparison of these five drinks and nothing else. There are more concentrated coffees on the market per fluid ounce, and we have never claimed otherwise — we compared ourselves against one of them in Bare Brew vs Death Wish, which is the honest version of that row.
The ingredient-count audit
Count the lines on the label — we did, from the published ingredient lists, on the flavors named above:
- Bare Brew: 2 — filtered water, coffee (100% Honduran Arabica).
- Reign (Melon Mania): 16 — carbonated water, citric acid, sodium citrate, L-leucine, natural flavors, caffeine, L-isoleucine, L-valine, sucralose, sodium benzoate, acesulfame potassium, niacinamide, magnesium lactate, coenzyme Q-10, pyridoxine hydrochloride, cyanocobalamin.
- Bang (Power Punch): 20 as listed — or 28 if you expand the single parenthetical that groups nine amino acids into one line item. We are showing the as-listed count; the expanded count is there so you can check our work either way.
Counts vary by flavor, which is why the flavor is named. The shape does not change: the energy drinks are formulated systems built to taste like candy with no sugar in them. That takes a lot of ingredients. Black cold brew gets its caffeine from the coffee itself, so the list stays at two. Neither approach is a moral judgment — but if your reason for switching is "I want to simplify what I drink," the count is the whole decision, and no flavor ranking will show it to you.
On price, read the scope carefully
We could not source a defensible national price range for any of these drinks, so we are not publishing one. What we can show is a single retailer on a single day: at H-E-B on October 27, 2026, Bang 16 fl oz and Reign 16 fl oz were both $2.48 a can, and the Celsius 12 fl oz was $2.47. Bare Brew is $4.50 a can inside our $53.99 12-pack, before our $8.99 flat shipping, which works out to $5.25 a can delivered on a single 12-pack.
Honest read: on caffeine per dollar at that one retailer, Bang and Reign both beat us — roughly 121 mg per dollar against our 71 mg per dollar at the shelf price of the pack, or 61 mg per dollar delivered. Switching for price alone does not survive the math, and prices on your shelf will differ from that snapshot. What the per-dollar row does not capture is the ingredient audit above — you are choosing between the cheapest 300 mg and the simplest 320 mg. Those are different purchases. The full delivered-cost breakdown, including how shipping spreads across cases, is in our office cold brew cost guide.
The bottom line for a Bang drinker
- Same dose, similar system, different brand: Reign — the only other 300 mg, zero-sugar, 16 fl oz can in the set.
- Cheapest caffeine: Bang or Reign, on the one-retailer snapshot above. Re-run it with the price in front of you.
- Same-or-more caffeine per can, two ingredients, no sweeteners: Bare Brew. No sugar. No dairy. Bare ingredients. Special blend of coffee and water — filtered water and 100% Honduran Arabica coffee, 320 mg of natural caffeine, 20 calories and 5 g total carbohydrate, shelf-stable, and it tastes like coffee because it is coffee.
Coming off energy drinks entirely rather than swapping brands? That is a different problem and we wrote it up separately in how to quit energy drinks. For where 320 mg sits against coffee rather than against cans, see our cold brew caffeine guide.

Label figures and ingredient lists re-read October 27, 2026 from published retailer nutrition panels for the flavors named in each row: Bang Power Punch, Reign Melon Mania, Celsius Raspberry Acai Green Tea, Alani Nu Cherry Slush. Bang's panel states total carbohydrate 0 g and total sugars 0 g but prints no calorie row, so no calorie figure is claimed for it here. Ingredient counts were taken line-by-line from those same published lists and vary by flavor. Prices are a single-retailer snapshot (H-E-B, October 27, 2026) and are not a national range; Bare Brew figures are our own published 12-pack price of $53.99 plus $8.99 flat shipping, every order, no minimum. Caffeine-per-fluid-ounce and caffeine-per-dollar figures are division of the published numbers shown. Re-run both with current shelf prices.
