It won't stay that way. The sour smell, vinegar and alcoholic, develops once it gets to the starving stage. It will take a few weeks to develops and a while longer to fully mature.
One thing about sourdough clubs is that they share years old sourdough mother around to keep it going. It's why I'm so darned annoyed at having lost the one I had in the fridge that was +2 years old. I'm having to start all over.
For now, it's a case with yours of replenishing it daily. I do mine when I get up and am making a coffee. Tiniest amount of old into new. Hence keeping a second jar available. The dirty was washed during the previous day and sterilized along with a teaspoon when i made my coffee.
The smell and taste comes with time. You'll be able to reduce the volume of flour used as well. No need to use 100g every day, drop to 50g when you know it's very well established, or even 25g and add less mother in accordingly. You actually need it to run out of flour to eat during the day to create that flavour. But hold fire on that for a bit yet. Now is getting it alive. It's still an infant and we need to get to being a toddler first!
