Not exactly - you can get liquid stevia in alcohol. But you probably won't like it if you bake a lot with the glycerite based one. The one in alcohol by comparison is not as mild, and you will really taste the bitterness if you try to use ONLY that as the sweetener in a baking recipe.

The main advantage of stevia glycerite is exactly that it does a better job in masking the stevia's natural bitterness if you go over, but yes, you definitely pay for it in carbs and calories.

For someone counting carbs very strictly, Stevia glycerite would really have no room in someone's macros, unless they were strictly limiting themselves to a couple of drops in their tea or coffee only, for example.

The stevia glycerite only has no carbs or calories per serving, but again, like many products, this is for sure a deceiving claim to make, because the amount that people use "per serving" is usually A LOT more than they claim a serving should be on the bottle. Even just for hot drinks, I can use a full glass dropper/stopper full, and that is A LOT of "drops".
