Bison, buffalo, goat and deer tallow are rendered fats from grazing ruminants, cousins of beef suet. In an American shop, buffalo tallow means bison fat. Where researchers have measured their fat, bison and deer come out close to grass-fed cattle on paper. Smell and supply set them apart, and that's why we chose beef.
We source 100% suet, the dense fat from around the kidneys, from grass-fed and grass-finished cattle on Montana family ranches, bought direct. For plain tallow on dry skin, I'd hand you Bare Silk ($34). It's suet tallow with four supporting ingredients and no water, and prices here are as of October 5, 2026.
Is buffalo tallow the same as bison tallow?
In the United States it's the same fat, since Americans call the bison a buffalo. True buffalo are Old World animals, the Smithsonian's National Zoo says, such as the Cape buffalo and the water buffalo. The zoo even files the plains bison under Bos, the cattle genus. I'll call it bison from here on.
Water buffalo are a different animal. FAO counts about 205 million of them worldwide, with more than 98 percent in Asia. River buffalo, about 70 percent of that herd, are the milk type, while swamp buffalo are raised mainly for draft power. In India and Pakistan, buffaloes give more milk than cattle. That's why I'd call the water buffalo a dairy animal first.
How do bison and deer fat compare with beef suet?
Bison has the thinner record. In a 2002 Journal of Animal Science study, Rule and colleagues measured the fat inside muscle from bison and beef cattle, with elk and chicken alongside. Range-fed bison came out similar to forage-fed beef cows and wild elk. Diet moved the numbers within a species, too: range bison carried more saturated fat in their muscle than feedlot bison did. I couldn't find a published profile of rendered bison fat.
Deer has better data. Cordain and colleagues (2002) tested the fat under the hide of 15 mule deer, among other wild ruminants, for the European Journal of Clinical Nutrition. That fat had the lowest ratio of polyunsaturated to saturated fat of any tissue they tested, 0.05 to 0.09. That's 5 to 9 g of polyunsaturated fat for every 100 g of saturated. USDA's beef tallow record works out to about 8 g, inside the same range, and our post on the fatty acids in tallow has the rest of beef's profile. The team found the wild animals' tissue fats similar to pasture-fed cattle and unlike grain-fed cattle.
| Fat | What I could read | Smell |
|---|---|---|
| Beef suet tallow | About 8 g polyunsaturated per 100 g saturated (USDA) | Nearly scentless rendered low |
| Bison, sold as buffalo | Muscle fat close to forage-fed beef cows (Rule 2002) | No study found |
| Goat | Lean carcasses, fat laid down late (Webb 2014) | A goat note tied to 4-ethyloctanoic acid |
| Deer | 5 to 9 g polyunsaturated per 100 g saturated (Cordain 2002) | No study found |
Does goat or deer tallow smell?
A 2014 article by Webb in Animal Frontiers ties the strong goat odor to 4-ethyloctanoic acid, a branched-chain fatty acid that also turns up in lamb and mutton. It's a fatty acid, so the note rides with the fat. Webb also notes that goat carcasses run low in fat, and that goats lay it down later in growth than other farmed ruminants.
For bison and deer, I couldn't find a study on how the rendered fat smells, and I won't guess. You'll read that deer tallow sets harder than beef. I couldn't find a melting point or a stearic acid figure for deer fat to check that, so it stays a claim here.
Mutton shares goat's branched-chain note, and mutton tallow vs beef tallow covers the sheep version. Emu oil, a bird fat, gets its own comparison. On intact skin, any of these fats should do the plain job of holding water in and relieving dryness. I couldn't find a study that tests any of the four on skin. It's cosmetic care, not a treatment. Your provider's plan comes first.
What do the words animal-based and unrefined mean on a label?
Animal-based skincare is a category word. It tells you an animal ingredient is in the jar, and it doesn't say which animal or which cut, how the fat was rendered or what else went in. The Codex food standard for named animal fats is narrower: it defines edible tallow as fat from bovine animals or sheep. Goat tallow and deer tallow borrow the name. The same standard has its own name, premier jus, for beef fat rendered at low heat from fresh internal fat such as kidney fat. Lard, by that standard, is rendered pig fat.
Unrefined is about what happens to a fat after it's rendered, and those steps have names. A 1994 FAO and WHO report describes two of them. Bleaching runs the fat through clay minerals that soak up color and break down hydroperoxides. Deodorizing is a steam distillation at 180 to 220 C under low pressure, and it carries off the aldehydes and ketones behind a fat's smell. The report adds that refining can strip carotenoids too, and an unrefined fat skips all of it. Ours is rendered for skin by our Montana render partner and strained fine, and we don't buy a bleached fat or a deodorized one.
Why did we choose beef suet?
We had four reasons for beef, and the cut of fat came first. Suet is the firm, crumbly fat from around the kidneys, and it's the same fat from the same place every time. Smell came second, because our suet is nearly scentless and our unscented jar smells like nothing. Third was the set. We pour dense and sell by weight, so a 2 oz jar is 2 oz of balm.
Supply was the last reason and the deciding one. About 500,000 American bison are managed as livestock, the Smithsonian's National Zoo says, with around 30,000 more in conservation herds. Rule's study showed diet moving bison fat, and goats carry little fat to begin with. A jar that has to match from batch to batch needs the same fat each time, so we buy ours direct from grass-fed and grass-finished cattle on Montana family ranches. We buy the fat. We do not run the ranch.
If you came for a plain ruminant fat on dry skin, Bare Silk is the jar I'd pick. It's grass-fed suet tallow with meadowfoam seed oil and organic jojoba oil. Vitamin E and arrowroot finish it. The Unscented original has no essential oils or fragrance, and there's a Lavender edition if you'd like a scent.
Start with Bare Silk ($34), five ingredients and sixty days to disagree.
Questions we hear
Is bison tallow good for skin?
Bison tallow should do what other rendered ruminant fats do on intact skin: hold water in and relieve dryness. I couldn't find a study that tests it on skin. The closest research, a 2002 study by Rule and colleagues, found range-fed bison muscle fat similar to that of forage-fed beef cows.
Does goat tallow smell like goat?
It can, since a 2014 article by Webb in Animal Frontiers ties the strong goat odor to 4-ethyloctanoic acid. That branched-chain fatty acid also turns up in lamb and mutton. It's part of the fat itself, so a goat render can carry the note into a jar. Beef suet rendered low is nearly scentless, so it's the easier start.
Is deer tallow good for skin?
Deer tallow should do the basic moisturizing job on intact skin, though I couldn't find a study that tests it there. In a 2002 study that included 15 mule deer, Cordain and colleagues found the fat under the hide had a polyunsaturated to saturated ratio of 0.05 to 0.09. Beef tallow's ratio is about 0.08, so on that measure they're close.
What does unrefined tallow mean?
It should mean the fat stopped at rendering and straining. A 1994 FAO and WHO report describes the refinery steps that can come after: bleaching through clay minerals to pull out color, and deodorizing with steam at 180 to 220 C to carry off smell. Ours is rendered for skin and strained fine, and we don't buy a bleached fat.
Go deeper
The beef tallow for skin guide covers what any tallow does on skin, and it's the place to start. Suet, not trim explains why the cut matters as much as the animal, and how to read a tallow label sorts out the words on a jar. If smell's your worry, will it smell like beef answers it. The one-to-one versions are mutton tallow vs beef tallow, lard vs tallow on skin and emu oil vs tallow.
