All 3 Id those bad ideas
Citric acid has a relatively strong flavor.
Roasted malts would do the trick too but youd be going to a brown/black color.
Bottled water no guarantee. A lot of those are highly mineralized as well. It would have to specifically be distilled or reverse osmosis water though.
And even with distilled or RO water youre pH is going to be 5.7-5.8.
Look for acidulated or sauermalt. It exists, just need to find the right term.
