Sour moist meat
Flavor Name: Traditional, Size: 4 Ounce (Pack of 1)
I had a hankering for jerky and found biltong instead. I didn’t know what made it different, but I was willing to try. I was very surprised how moist it was!! It’s better than the jerky here. If I wanted to gnaw on leather then I’d get my belt instead of paying money for dried meat. I liked that it didn’t have sugar. However , the flavor was confusing. It was mostly sour, like too much vinegar. Other reviewers mentioned that too and I must agree. I’m not sure how it’s suppose to taste but this experience makes me hesitate buying any more.

Rancid, Nasty, biltong shavings
Flavor Name: Traditional, Size: 4 Ounce (Pack of 1), Flavor Name: Traditional, Size: 4 Ounce (Pack of 1)
This Ayoba Biltong has an OK flavour, but the black pepper is excessive. About 20% of the shavings are rancid, which means that every 5 shaving pinch you put in your mouth is practically guaranteed to have a rancid flake. The rancid flakes are bitter. acrid and foul, and this nastiness completely overpowers the biltong flavour, even the excess black pepper taste. I believe the rancidness comes from the white bits of fat attached to the meat, but who wants to sort and clean these biltong bits?
DO NOT BUY!!!!
FYI - I grew up in Swaziland and Botswana, and ate pounds and pounds of biltong. I even made Biltong while deep in the Okavango Delta.

Excellent flavor and texture to this jerky with no sugar makes it my new favorite
Flavor Name: Traditional, Size: 4 Ounce (Pack of 1)
I have recently adopted a low carb, high protein diet combined with weight training, so I'm always looking for new sources of protein. I use protein powder as little as possible, and eat more from natural sources.
I have a brand of beef jerky I really like, but traditional beef jerkies have a lot of sugar (10g protein to 6g of sugar). Biltong, however, has more protein per oz (16g) and 0g of carbs or sugar. Simple ingredients, and nothing funky. So a big win on the nutrition front.
That is great, but what won me over was the flavor. It has a nice hearty flavor, and has a little wetness to it that makes the texture nice to chew. I have tried another brand of biltong, but I found it too dry for my taste (kinda of like chewing on plastic). So another win on flavor and texture.
Pricing is okay. Good beef jerky is not cheap, so you get what you pay for. I would like to buy in bulk, so bigger packages with better discounts would be a good offer I would jump on immediately.
