Fermentation vs Temperature
John Keske did some experiments on the impact of temperature during fermentation on the aroma and flavour of the finished beer.

Water Chemistry and brewing ions
Our resident Chemist, Glen Napthali, researched which salts matter to your beers flavour and mouthfeel. There is also a summary of typical values for Hobart's mains water supply.
