Pistachio Milk vs Hemp Milk: Compared

Pistachio milk and hemp milk are both dairy-free plant milks, but they sit in different lanes: pistachio milk is usually a touch higher in calories and fat, while hemp milk is lower in calories and prized for its omega-3 content, and the single biggest practical difference is that pistachio is a tree-nut allergen and hemp is not. If you are weighing them up, your decision often comes down to allergen safety, the fat profile you want, and how each behaves in a cup of coffee. Below is a sourced, side-by-side look, with the limits stated honestly.

How do pistachio milk and hemp milk compare per cup?

The quick version: for unsweetened versions, a whole-nut pistachio milk runs higher in calories and fat than hemp milk, while protein is modest and broadly similar for both. The figures below are per 1-cup (8 fl oz / 240 mL) serving, tied to named products. Pistachio milk varies a lot by brand. A whole-nut blend like Three Trees lands near 100 calories, while a leaner barista-style milk like Táche is closer to 50.

Approximate; per-serving values vary by brand, by sweetened vs unsweetened, and by fortification. Some hemp milks add calcium, vitamin D or B12. Three Trees pistachio nutmilk also contains organic almonds and almond extract, so it carries two tree-nut allergens and is not single-ingredient pistachio. Táche numeric values draw on aggregator data pending a label re-check.

For context, both of these milks are low in protein next to cow's milk, which has about 8 g per cup. University of Florida extension guidance (FS420) notes hemp milk is "much lower in protein than cow's milk" and cautions it should not be a complete cow's-milk replacement for children for that reason. The same modest-protein limit applies to pistachio milk. If protein is your priority, see our notes on pistachio milk protein and the broader pistachio milk vs cow milk comparison.

What about the fats: is hemp milk's omega-3 a real advantage?

Hemp's reputation rests on its fat profile, and that reputation is earned at the seed level. A peer-reviewed review of dietary hempseed reports that hempseed oil is rich in linoleic acid (omega-6, around 56 g per 100 g) and alpha-linolenic acid (omega-3 ALA, around 22 g per 100 g), plus gamma-linolenic acid, with an omega-6:omega-3 ratio that normally falls between 2:1 and 3:1, a proportion the authors describe as proposed to be ideal for a healthy diet.

Two honest limits. First, those figures are for hempseed and hempseed oil, not for a cup of hemp milk, which is mostly water; the absolute omega-3 in any given hemp milk is far lower and brand-dependent. Second, the idea of one "ideal" omega ratio is genuinely debated in nutrition science, so treat it as what the source reports rather than settled fact. Pistachio milk, by contrast, leans toward monounsaturated fat, in line with the pistachios it is made from. See are pistachios good for you for the whole-nut picture. Neither milk is a meaningful omega-3 supplement on its own.

Which is safer for allergies?

This is the clearest difference. Pistachio is a tree nut and one of the FDA's major food allergens, so it must be declared on labels; hemp is not a tree nut and is not on the major-allergen list. That makes hemp milk a common choice for people with tree-nut allergies. Pistachio milk is unsuitable for anyone avoiding tree nuts, and it is worth repeating that some pistachio milks, including Three Trees, also contain almond, adding a second tree-nut allergen. If your reason for switching is allergy rather than taste, hemp generally has the edge. For more on the dairy-free angle, see is pistachio milk dairy-free.

One more point on hemp: commercial hemp seed contains only trace THC, far too low for any psychoactive effect, so hemp milk will not get you anywhere near intoxication.

How do they taste and perform in coffee?

Flavor is where personal preference takes over. Hemp milk tends to be nuttier and slightly earthy or grassy, with a thinner body. Pistachio milk is creamier with a mild, faintly sweet, nutty taste, a profile that has made it popular in cafés. If latte texture matters to you, a barista-style pistachio milk like Táche is built to steam and foam, which is why it shows up so often in a pistachio milk latte or a pistachio matcha. Hemp milk can foam but is generally less creamy. For the full flavor rundown, see pistachio milk taste.

Which should you choose?

Choose hemp milk if you need a tree-nut-free option, want fewer calories, or specifically value its omega-3 profile. Choose pistachio milk if you want a creamier, café-friendly texture and a richer nutty flavor, and tree nuts are not a concern. Both are low in sugar when unsweetened, and both should be read off the actual carton, since sweetened versions can carry 20 g or more of carbohydrate per serving.

Allergy note

Pistachios are a tree nut, so pistachio milk is unsuitable for anyone with a tree-nut allergy, and note that some pistachio milks, such as Three Trees, also contain almond, a second tree nut. Hemp is not a tree nut and is not one of the FDA's major food allergens, which is why hemp milk is often chosen as a tree-nut-free alternative; both pistachio and hemp milk are dairy-free and suitable for vegan diets. Allergens, ingredients and cross-contact practices vary by brand and facility, so always read the label and check with a medical professional if you have any allergy concerns.
