Get three things right: the amount of coffee, the grind and the pour. Your V60 will taste sweeter and cleaner.
Steps
Rinse the paper filter with hot water and discard the water. It removes paper taste and warms the brewer.
Add 15 g of freshly ground coffee and level the bed with a gentle shake. Put everything on the scale and tare it.
Pour about 30–40 g of water to wet all the coffee. Wait 30–45 seconds.
Pour slowly in circles, keeping the water level steady, until the scale reads 250 g.
Let it drain. If it finishes much faster than 2:30, grind finer next time; much slower than 3:30, grind coarser.
Questions

Grind a little finer or pour a little slower.
And if it tastes bitter?
Grind a little coarser.
