There is a lot of confusion — especially on the web — when people talk about 100% juices. The fact is, juices are rarely 100% acai berry. When an acai berry is mashed and hot bottled it is a purée The bottles of acai juice you see in the big stores — and in lots of places online — are not purée, and quite often they are mixed with other juices and are most certainly not 100% pure.Because the acai berry is so very volatile it cannot be transported or kept without processing. The less processing done, the more natural the product, but also the more difficult it is to keep. Supermarkets require the products that they sell to be able to be kept on boats, on wagons and on shelves in warehouses for a long time; 100% acai berry purée just wouldn’t stand this kind of treatment.Fortunately for us, acai berry purée is available online where retailers are much more flexible about how much they order, when they order it, and how much they are required to store. Acai purée is only available online, and only certain online retailers sell it, but it is worth the effort to hunt it down and buy some.
