Birster Posted August 25, 2017 Share Posted August 25, 2017 Hi, How often should you change the water in the jacket of a bain-marie still? Also, is it best using distilled water or any water would do? The jacket is in stainless if it matters. Thanks in advance. Link to comment Share on other sites More sharing options...
whiskeytango Posted August 25, 2017 Share Posted August 25, 2017 Don't know i run oil. I would guess that it doesn't matter either way on the water and just keep it topped of and you will be fine. Why are you not running oil? Link to comment Share on other sites More sharing options...
Birster Posted August 25, 2017 Author Share Posted August 25, 2017 I thought you had more fine tuning control with water than you have with oil. Why did you choose to use oil instead of water? what are the pros? Thanks, Link to comment Share on other sites More sharing options...

Foreshot Posted August 25, 2017 Share Posted August 25, 2017 The closer the wort gets to boiling the less effective water is with heat transfer. You can only heat regular water to ~212. Heat transfers work better the bigger the differential is between the two temps. Link to comment Share on other sites More sharing options...
bluestar Posted August 27, 2017 Share Posted August 27, 2017 Don't use distilled water, it is corrosive. Depending on what metal comes into contact with the bain marie, you may need to condition it to minimize corrosion. You may want to reduce the mineral content to avoid scaling, or add a descaler, but you don't want to go to completely distilled water. Your bain marie is essentially a boiler, treat it as such.
