Comparison
Pistachio Milk vs Almond Milk: The Full Nutrition Breakdown
A closer, label-by-label look at how pistachio and almond milk compare on calories, fat, protein and sugar.
Quick answer
Per cup, pistachio milk is usually a little higher in calories and fat than almond milk, while unsweetened almond milk is one of the lowest-calorie plant milks. Both are low in protein and calcium unless fortified, so the biggest differences come from added sugar and fortification — compare like with like.

The honest headline
Both drinks are a nut blended with water, so most of what's in the carton is water. That means the numbers are driven less by which nut it is and more by three choices the maker (or you) makes: how much nut, how much added sugar, and whether it's fortified with calcium, vitamin D and B12.
The numbers, side by side
| Per 1 cup (240 ml), unsweetened | Pistachio milk | Almond milk |
|---|---|---|
| Calories | ~50–60 kcal | ~30–40 kcal |
| Protein | ~2 g | ~1 g |
| Fat (mostly unsaturated) | ~4–4.5 g | ~2.5–3 g |
| Carbohydrate | ~2.5–3 g | ~1–2 g |
| Sugar | ~0–1 g | ~0 g |
| Calcium | Low unless fortified | Low unless fortified |
| Typical price | Higher (specialty) | Low (widely stocked) |
| Water use † | ~25.5 gal/oz | ~97.2 gal/oz |
Approximate values for unsweetened versions (per 1 cup / 240 ml); they vary by brand — verify against current labels. Pistachio figures are consistent with Táche unsweetened (~50 cal, 3 g carbs, no added oil). † Water-use figures are from brand/vendor sources, not peer-reviewed LCA datasets — see the environmental note below.
Calories and fat
Unsweetened almond milk is typically one of the lowest-calorie plant milks. Pistachio milk is usually a little higher in calories and fat, which is also why it tastes creamier. Both fats are mostly unsaturated. The Harvard Nutrition Source notes nuts fit well within a balanced diet.
Protein
Both are low in protein compared with cow's or soy milk — generally only a gram or two per cup unless the product is fortified or uses a high nut content. Neither is a reliable protein source on its own.
Sugar and fortification
This is where labels diverge most. A sweetened version of either can carry several grams of added sugar per cup; unsweetened versions are minimal. Fortified versions add calcium, vitamin D and B12 to better stand in for dairy — homemade milk won't have these unless you add them.
Environmental footprint
Peer-reviewed life-cycle data compiled by Our World in Data (from Poore & Nemecek, and consistent with World Resources Institute analyses) shows that plant milks — almond, oat, soy — all use far less water than dairy, with almond the most water-intensive of the plant milks. Pistachio milk isn't yet in those datasets, so its comparison with almond relies on brand sources: Táche, citing UNESCO-IHE data, reports almond's water footprint at roughly four times pistachio's (97.2 vs 25.5 gallons per ounce), i.e. pistachio uses meaningfully less water than almond. Some vendor estimates (e.g. Milk Depot) suggest a smaller gap, so treat the exact ratio as indicative. The honest caveat: pistachio's environmental numbers come from brand/vendor sources, not peer-reviewed LCA, so read them as approximate.
How to choose well
Compare like with like: unsweetened against unsweetened, fortified against fortified. For everyday use pick an unsweetened, fortified option of whichever you prefer the taste of.

Which is better for weight loss?
If your only goal is the fewest calories, unsweetened almond milk edges it, at roughly 30–40 kcal per cup versus pistachio milk's ~50–60. The gap is small, though, and pistachio milk's extra creaminess can be more satisfying, which may matter more than 20 calories. For either, the bigger lever is choosing unsweetened — a sweetened carton can add more calories and sugar than the difference between the two milks. Neither is a weight-loss food in itself; they're just light, flexible swaps for dairy.
Label checklist
When you're standing at the shelf, scan four lines:
- Sweetened or unsweetened? Unsweetened for everyday; sweetened is a treat.
- Fortified? Look for added calcium, vitamin D and B12 if it's replacing dairy.
- Nut content / first ingredients? More nut, more flavour and nutrients.
- Additives? Minimal-ingredient versions exist for both if you prefer a short list.
The bottom line
For flavour and coffee, pistachio milk; for lowest calories and cost, almond milk; for nutrition, they're close and depend far more on sweetening and fortification than on which nut it is. Buy unsweetened and fortified, of whichever you like the taste of — or make pistachio milk at home and control it all yourself.
