Basic water question

[LokiSS]

Hi,

When we begin heating water for the mash, it is better to use cold tap water or its possible to use hot tap water ?

Thanks

I never use hot water because it has gone through the hot water tank and I am nervous to think of what it might have picked up in there. I don't really have any proof that it did but just the thought is enough to make me not use it.

Test it yourself..take a cold water sample, and a hot water sample and chill them in the fridge, taste them side by side and see what you think ! It's not scientific, but I always start with 120F water and it speeds up my brew day !

Yes, speeding up brew day and saving on gaz/electricity is the main purpose of this question, just wanted to know if others where using hot tap water with good result, before I scrap a batch.

By the way, all this juice is boiling for 60-90 mins after ...

Just curious what people arround here think of this.

Not sure if you are saving much on gas/electricity since the water heater will have to burn some energy to replace the hot water...

Maybe LokiSS has solar or geothermal hot water.

Or maybe he lives in an apartment with free hot water, like me.
