Thank you for the input!
We are aware of the result of using a copper condenser with both fruit washes and gin, however the condenser cannot be changed at the moment. We ended up "salting" out the acid via addition of calcium carbonate which in turn removed much of the already present copper salts. Given that changing our current set-up is more invasive than altering pH, my question still remains unanswered in that we need to adjust pH at some point to reduce acidity and thus production of copper salts and the pass through of volatile acids but are unsure if this should happen before our initial stripping run or after .
