I have bought the raw sugar several times, (brown granulated) but find I use twice as much to get the sweetness I use in my coffee. Thats the only thing I use sugar in...Don’t know why it doesn’t have the same sweetness as granulated. Have you had this problem with raw sugar?
I only tried raw sugar several years back and didn't particularly like it. I now use stevia (liquid) for most purposes, and sweeten coffee with part stevia and part a product called Natra Taste Gold (Dextrose, Maltodextrin and Sucralose). That comes very close to a sugar flavor, and is the only thing I use that product for.
I'm mildly hypoglycemic so avoid most all added sugar. And, it is harder to find a good sugar substitute for coffee than for most other things.
There are some new products that contain stevia and some other natural sweeter. I tried the one called Truvia and liked it for coffee. Got that at Wal-mart, but haven’t remembered to buy more. If you’re looking for a sugar sub that taste like sugar in coffee, one of these might work for you:
Those products are doing what I’ve been doing: mixing stevia with some other sugar sub to get a more sugar like flavor with little or no actual sugar. - You can Google and find others, as I think stevia was recently approved as a sugar sub.
