This one was a little hard, because artificial sweeteners are something I usually avoid. I am by no means 100% crunchy, but this is one area where I mostly stick with sugar. Honey or molasses aren't bad for some things, but they won't always work, and straight up stevia tastes like dirt, IMO. Yes, I know sugar is highly processed, but it still seems better than something made totally in a lab.
Nectresse is interesting, though, because it claims to be a 100% natural derivative from monk fruit. Other sweeteners have made similar claims, but in the end turned out to be more chemical than they portrayed, so I'm skeptical. Obviously there is processing involved to turn a plant extract into a granulated product, so I have a problem agreeing that it is 100% natural. What I'm mostly concerned with is whether the processing changes it into something worse for me than limited amounts of sugar. I still have more research to do on the product before I can really say whether or not this is something I would regularly use.
As for the taste, though, compared to Splenda, the "blue stuff" or the "pink stuff", I would go with Nectresse. It does have a little of the artificial sweetener aftertaste, but nowhere near as bad. I could see someone easily using it in place of sugar without much problem. Just be sure to start with less than you would use if it were sugar. It is sweeter.
Overall: A (Based solely on taste compared to other sweeteners. If I find out it makes people grow an extra head or something, I will change my grade.)
Price: $6.99 for 5.9 oz container, or $3.99 for a box of 40 packets.
Would I repurchase: Maybe. I don't use sweeteners often, but I do like to have some on hand for guests. Unless I find out this is totally horrible for you, I would probably buy either Nectresse or Truvia, whichever is cheaper.
In the interest of full disclosure, I received these products complimentary from Influenster for testing purposes. I will be totally honest in my reviews, because I would hate to encourage my readers to waste their money on a sub par product.
