How Much Sugar Is in Pistachio Milk?
A clear, label-based answer: unsweetened pistachio milk has almost no sugar, while barista and sweetened versions add cane sugar. Here's how to tell them apart.
Quick answer
It depends almost entirely on whether the carton is unsweetened or sweetened. Unsweetened pistachio milks have roughly 0-1 g of sugar per cup (240 ml) and 0 g added sugar. Sweetened or barista versions add cane sugar and run higher, around 7 g of sugars per cup for Táche Original Barista. Always read the label, since formulations differ by brand and product line.
How much sugar is in pistachio milk depends almost entirely on one thing: whether it's labeled unsweetened or sweetened. Unsweetened pistachio milk has roughly 0 to 1 gram of sugar per cup (240 ml), and 0 g of added sugar, while sweetened and "barista" blends fold in cane sugar and run noticeably higher. Here's the label-based picture, and how to read a carton so the number isn't a surprise.
Why unsweetened pistachio milk has so little sugar
Whole pistachios are naturally low in sugar, and the milk dilutes them heavily. Per the USDA, 100 g of raw pistachios contains 7.66 g of total sugars (mostly sucrose) alongside 27.18 g of carbohydrate and 10.61 g of fiber. A glass of unsweetened pistachio milk is mostly water with a relatively small amount of nut, so only a trace of that natural sugar carries through, about 0 to 1 g per serving. Importantly, none of it is added sugar: the residual is the same naturally occurring sugar found in the nut itself.

Sugar by brand (per cup)
| Pistachio milk (per cup / 240 ml) | Sugars | Added sugar |
|---|---|---|
| Táche, unsweetened classic | ~0 g | 0 g (marketed sugar-free) |
| Elmhurst, unsweetened | ~0 g | 0 g (no sweetener listed) |
| Three Trees, organic unsweetened | ~1 g | 0 g |
| Táche, Original Barista (sweetened) | ~7 g | added cane sugar |
Approximate, from brand labels and retailer listings; verify against current packaging. Three Trees is an almond + pistachio blend, not 100% pistachio.
The unsweetened products are clustered near zero. Táche's unsweetened classic is marketed as "dairy-free, sugar-free, oil-free." Elmhurst's unsweetened pistachio lists only filtered water, pistachios and Himalayan pink salt, no sweetener at all. Three Trees, an organic almond-and-pistachio blend, shows about 1 g of sugar with 0 g added. The outlier is Táche's Original Barista, whose ingredient list includes cane sugar and which carries about 7 g of sugars per cup. Treat that 7 g as approximate, since published figures vary slightly between roughly 7 and 8 g, and note that Táche sells several SKUs (Classic, Vanilla, Barista, Unsweetened Barista) that differ, so the name on the carton matters.
How to read the label
Two lines on the Nutrition Facts panel tell the whole story. Total Sugars counts all sugar, natural and added. Includes Added Sugars, printed just below it, is the figure that counts toward dietary-guideline limits on added sugar. On an unsweetened pistachio milk, both lines should be at or near zero. On a sweetened or barista version, the "Includes Added Sugars" line is where the cane sugar shows up. The words "barista" and "original" often signal that sweetener has been added, so they're worth a second look. One caution: "sugar-free" does not mean calorie-free or carb-free, unsweetened pistachio milk still contains a little carbohydrate and fat from the nuts.
How pistachio milk compares to other milks
| Per 1 cup (240 ml) | Sugars |
|---|---|
| Pistachio milk, unsweetened | ~0-1 g |
| Oat milk, unsweetened | ~4 g |
| Pistachio milk, sweetened barista | ~7 g |
| Cow's milk (skim, low-fat, whole) | ~12 g (lactose) |
Approximate; sweetened and flavored plant milks add more. Source: UF/IFAS Extension and brand labels.
Unsweetened pistachio milk is lower in sugar than cow's milk and typically lower than oat milk. Cow's milk carries about 12 g of naturally occurring lactose per cup, and unsweetened oat milk around 4 g. A sweetened pistachio barista blend at about 7 g sits below cow's milk but well above the unsweetened version. For the full head-to-heads, see pistachio milk vs oat milk and pistachio milk vs cow milk.
What this means for blood sugar
For the lowest sugar, choose a carton labeled unsweetened. Because they're low in sugar and carbohydrate, unsweetened plant milks are often preferred by people watching blood sugar, but pistachio milk doesn't treat, prevent or manage any condition, and individual needs vary. If you're managing diabetes, follow personalized advice from your doctor or dietitian rather than a general rule of thumb. The broader nutrition picture lives at pistachio milk benefits, are pistachios good for you, and across the nutrition hub. If you make your own homemade pistachio milk, you control the sugar entirely: leave out dates or syrup and it stays at the nut's natural near-zero.

Allergy note
Pistachios are a tree nut. Pistachio milk is unsuitable for anyone with a nut allergy. It is naturally dairy-free and vegan, which is why it appeals to people avoiding lactose.
