Hello...I have got that experience as well. This is fairly simple to solve however you have to use some beans to test for the best result and for every single bean as well.

The sour taste is caused by under extraction, few reasons

1. Water temperature
Water rise before it reaches 92C, imagine you are just using 7X C water to brew the coffee what would happen. To fix it, turn the fire to mid-high or even lower to make sure water boil above 92C. (but don't burn the coffee by extending the brewing time)

2.Dosing
Don't change the finest of your grinder at very beginning, to make it easier...change other factors first. Try to put a bit more coffee powder in the basket...tap the basket few times to compact coffee powder. Form a little dome shape is fine, water pressure will help u do the tamp.

3. Grinder
This is the final factor that you would consider in your case, becuase changin the finest is not easy. Or...you might consider get a better grinder to make more consistent grounds.

I hope it helps. I also have a Brikka for like 2 years. Having fun with it and the can make good moka espresso if you know how to use it. ^^
Good luck!

um...ah...I know how to solve this problem la...

Use boiled water instead of room temp. water.

As this can make sure water is over 92C and not heating coffee powder too long.

Use mid heat (adjust yrself if needed), let water in the bottom part slowly build up pressure and push water up.

Sometiimes you might find that water can't get through the coffee cake, so u hv to adjust the fire a bit higher to push water up.

Hope you enjoy this process, after you hv experimented the perfect balance. All the trial n errors are worth it. The experience is something that espresso machine cannot offer.^^
