Customer ReviewsAuthor: aembermoon Compared to other stevia extracts I have tried, this one seems the least bitter & it dissolves very easily, as opposed to another popular "shaker" formulation. You don't need much powder to achieve sweetness. For example, I keep it in a salt shaker & use 2 light shakes for a 10 ounce cup of coffee, 1 shake for tea. Newer products are in the pipeline with 97% & 99% rebaudioside A, so it would be nice to know exactly what % over 90 of rebaudioside A the Star West product has. I get this product from a local merchant, so I can buy just what I need at a very reasonable price compared to other products on the market, even with a markup. A good deal on a high quality product.
