Actually I'm being conservative. In my case it was closer to 90% savings.
I'm very pleased with this product.
I had been using KAL stevia liquid. The recipe I arrived at doesn't taste exactly the same as KAL, but then I've discovered that there are tiny differences in taste from pouch to pouch of this powder too. The main negative thing most people notice with some stevia products is a bitterness, or aftertaste, and if you REALLY overuse this, it can produce a slight bitterness. Just being aware of that has made this a complete non issue for me. I use it all the time and don't have any problem.
I tried a small pouch first to experiment. Now I buy by the kilo.
Here's the recipe I arrived at. I experimented around before I settled on this. It's pretty close to the strength of the KAL liquid I was using. Maybe try a scaled down amount to see if it suits you.
1 Kilogram = approx 8 1/2 cups powder
I use 1 cup powder with 16 oz of distilled or purified water. I suggest avoiding tap water altogether.
One Kilo/powder with 4 quarts of water should yield approx 160 oz, (or 20 8oz bottles)
At approx $45 a kilo, an 8oz bottle costs $2.25!
Notes on mixing and using:
As a powder, it can be sprinkled in coffee or tea, but I found it was hard to measure accurately, and it takes a fair amount of stirring. So I decided to convert to liquid form.
The powder not mix thoroughly right away. A substantial amount will linger as a thick paste-like glob, but the answer is to give it time to dissolve on its own. After the initial stir, leave it be for about 1/2 hour and it will be much more mixed in. Stir again and wait again. A few more cycles and it will have all dissolved. It will have an amber color.
I've only mixed with room temperature water. Hot would probably work more quickly but it's not necessary. And because heat might have other consequences I use room temp water.
Storing for months in refrigerator is not a problem.
Lastly, the dropper bottle can accumulate a sticky white residue around the screw-on top.
It can be annoying to have to keep cleaning it. A very slight amount of olive oil rubbed around the treads on the top of the bottle greatly reduces this problem.
