The Pistachio Milk Label Study: What's Actually in Every Major US Brand (2026)

Pistachio milk sells at a premium on the promise in its name — but the cartons vary far more than the shelf suggests. So we did what nobody in this small category seems to have done: put the published label and price of every major US pistachio milk side by side and worked out what you're actually paying for.

This is a desk study of public data, compiled on 10 August 2026 from each brand's own product pages and major retailer listings — every figure links to its source below. It is independent and affiliate-free: we earn no commission, we don't speak for any brand, and this site is not affiliated with Táche (whose official store happens to be pistachiomilk.com; you are reading pistachiomilk.org). Recipes and prices change, so treat the current carton as the final word.

The headline findings

1. Only one product is pistachios-only. Elmhurst Unsweetened lists just filtered water, pistachios and salt. Every other lead product in the category adds another base ingredient or stabilisers.
2. No brand tells you how much pistachio you're getting. Not one product we checked publishes a pistachio percentage. The closest thing to a quantified claim is Elmhurst's "27 whole pistachios in every glass."
3. The "pistachio" protein often isn't pistachio. The highest-protein carton (WholeMoon, 6 g per serving) gets there with whole roasted soybeans; Three Trees blends in organic almonds; Elmhurst's Barista Edition adds rice; 137 Degrees blends cashews.
4. You're paying 2.5–5× the price of almond milk. We recorded $4.66 to $9.65 per litre across the category, against about $1.94 per litre for a benchmark half-gallon of Almond Breeze.

The comparison table

Prices are the best single-carton equivalent we could record on 10 August 2026 (direct multipacks divided per carton; retail listings as shown). Nutrition is per cup (8 fl oz) serving as published. The full dataset, including price bases and source URLs for every figure, is downloadable as a CSV file — free to reuse with attribution (see citing this study below).

Which products count as "major"?

We included every pistachio milk that met all three of these criteria on 10 August 2026: sold in the US (nationally distributed at retail, or direct-to-consumer with US-wide shipping); pistachio named as the headline ingredient of the product; and a published ingredient list and price we could link to. That yields five brands and six lead products: Táche, Elmhurst 1925 (two products), Three Trees, WholeMoon, and 137 Degrees. One judgement call to be transparent about: 137 Degrees is a Thai brand reaching the US through import listings rather than national distribution, so its pricing is a range across listings rather than a single shelf price. Private-label and food-service-only products with no public listing were out of scope, as were pistachio creamers — a separate category we cover on the creamer hub. If we've missed a product that meets the criteria, tell us and we'll add it.

What the labels don't say

US food labelling doesn't require a brand to state what percentage of a product is the ingredient it's named after — unlike EU rules, where a "pistachio drink" would have to declare its pistachio percentage on the label. In a category where the nut is the whole sales pitch, that gap matters: a carton that is 2% pistachio and one that is 8% pistachio can carry near-identical front labels at very different costs to make.

Without percentages, two public clues do most of the work:

• Ingredient order. Ingredients are listed by weight. "Filtered water, pistachios, salt" is a different product from one where soybeans or rice appear immediately after (or inside) the pistachio milk.
• Protein arithmetic. Pistachios are about 20% protein, so a genuinely nut-dense cup shows it in the protein line — if the protein is coming from pistachios. Where a label pairs a high protein figure with soy or almond in the ingredient list, the extra grams aren't necessarily pistachio.

This isn't an accusation of wrongdoing — blending is legal, labelled, and sometimes makes a better-textured or more affordable drink. Our point is simpler: the information needed to compare pistachio milks on pistachio content doesn't exist publicly, and shoppers paying $9 a carton might reasonably want it.

The price picture

Per litre, the category splits into two tiers. The pure-or-nearly-pure nut milks (Elmhurst Unsweetened, Táche, Three Trees) cluster at $9.50–$9.65 per litre. The blended, supermarket-oriented products (WholeMoon at $4.66, Elmhurst Barista at $7.39) come in meaningfully cheaper — with the blending arguably part of how.

Against the wider plant-milk shelf, even the cheapest pistachio milk is over twice the price of a benchmark almond milk, and the premium tier is roughly five times. Whether that's worth it comes down to how much you value the flavour and body — our take on when it is and isn't is in best pistachio milk, and if the economics annoy you, making your own remains the cheapest route to a high-pistachio glass.

How to use this at the shelf

• Want maximum pistachio? The shortest ingredient list wins: Elmhurst Unsweetened is the only pistachios-water-salt product in the category, and the only one that quantifies its nut content. See our Táche vs Elmhurst comparison for how the two flagships differ in practice.
• Want it for coffee? Barista formulas trade purity for steam performance — that's what the gums and rice are doing. Our pistachio latte guide covers ratios and technique.
• Want protein? Check where the protein comes from. WholeMoon's 6 g is real, but it's a pistachio-soy blend, not evidence of more pistachios.
• Want the trade-offs by brand? The brands hub links our full, honest notes on every maker in the category.

Methodology, limitations and corrections

We compiled this from each brand's own product pages and major retailer listings on 10 August 2026; every figure links to its source above, and the downloadable dataset records the price basis for each row. Per-litre prices are computed from the listed pack size and the best single-carton equivalent price (direct-to-consumer multipacks divided per carton, retail listings as displayed) — the fairest like-for-like the category allows.

The limitations are worth stating plainly. This is a desk study of published label data: we did not lab-test any product, so we can't verify what's in the carton beyond what the label declares. Prices are a single-day snapshot and vary by retailer, region and promotion — treat them as an August 2026 baseline, not live prices. Protein figures are as published per cup, subject to US labelling rounding rules. And because no brand discloses a pistachio percentage, our reading of "how much pistachio" relies on ingredient order and protein arithmetic, which are indicative rather than exact.

Products reformulate and reprice constantly in this niche. If you're a brand and a figure here is out of date, or you're willing to disclose your pistachio percentage, we'll gladly update this page and say so — the contact route is on our about page.
