how do i know if wine is fermenting

how do i know if my wine is fermenting. today i can hear it fizzing but no foam or bubbles like what people said it should be doing.

You should always take a gravity reading of your must BEFORE you pitch your yeast. Then, subsequent gravity readings will tell you if your wine if fermenting. You may also see some physical activity, but you can't count on that to tell you what's really going on.

Even if you miss the initial gravity reading, take one now. Then take one in a few days. If the second reading is lower than the first, your wine is fermenting. If it is at or below 1.000, you are just about done with fermentation.

If it is fizzing, it is fermenting.
If you can see bubbles escaping from the airlock, it is fermenting.

The problem starts when you do not hear fizzing anymore. Then it could still be fermenting but the rate can be so slow that you will not notice it.
Same goes for bubbling in the airlock.
One bubble a week is slow, but still fermenting.

An airlock is the best way (besides taking a hydrometer reading each time, which in my opinion is a waste of time) to see if fermentation is going on.

NOT bubbling does not mean that the wine is ready.
It only tells you that fermentation has stopped, which is an entirely different thing.

Good point, Luc. I was probably a little too quick to dismiss physical activity. If you hear fizzing or see bubbles, it's a sure thing you are fermenting.

If you don't see or hear any physical proof of fermentation, though, don't count on it being complete.

That good old soud of a soda pop is a great sign.
