I tried this...
Real Ale Coopers kit
First I collected 19L of RO water. Into which I placed a chunk of Himalaya Pink Rock salt size approx 50mm wide x 30mm tall x 40mm deep. A sizeable chuck. Within a few hours it had dissolved completely.
Then brewed as normal, 2 weeks in primary, then 6 weeks in secondary.
This was back in June....Im still drinking this stuff right now....It carbonated quite well, with awesome head and that unmistakable salty taste
At first it was a bit overbearing....but I must admit, the salt really does balance off the bitterness of the Real Ale...
I've also found, if you eat deep fried snacks with the beer, it works really well.
I wouldnt do it again, but I've just put down a International Lager with a 1/4 of the salt I used previously.
I'll post back soon.
Himalaya rock salt is millions of years old (primordial oceans)....
I wouldnt try it with processed mineral NaCl....that stuff will kill ya.
