Reverse Osmosis vs Filtered Water

[SwellSpirits]

I was curious if anyone has used non-RO water to proof their gin and if that has had any set-backs. e.g. chill haze or louching.

On small test batches I have been using just filtered water with no issues, but perhaps once I get up to 1000 liters per batch I might run into something different.

Any advice on this would be great.

Our customers use RO water to proof.

We use a filter system for making de-ionized water.  No problems.
