Mash liquor

Post by Oliver »

For my last few brews I've taken my mash liquor straight from the hot water tap (we have an instant gas HWS) into the mash vessel, which in my case is a Braumeister.

Apart from saving time, I figure it also saves money by doing most of the initial heating with gas rather than electricity.

The beers have turned out fine but I was wondering if there's any potential problem with doing this. I can't think of any but there are far greater brewing minds out there than mine.

Does anyone else do it?

Cheers,

Oliver

My palate is not refined enough to notice if there was any flavour concerns.

I doubt I could tell the difference either.

I use hot tap water for liquor but leave it in my mash mash vessel or buckets over night to shed as much chlorine as possible. This won't work if your water is chloramine treated though.

Easiest way of checking the quality of your hot water is to cool some down then taste it.

I wouldn't due to the likely higher metal content. I think I tested the hot tap water once when I also tested my rainwater. Will see if I can dig out the results.

I just took some water straight out of the (instant) hot water tap, let it cool and drank it. The missus and I both agreed that it tasted like, well, water.

It tasted fine. There was no hint of any odd flavours that may have been the result of it having gone through the HWS.

So from now on my mash liquor will be coming straight from the hot water tap.

Cheers,

Oliver

I reckon you'd have no worries with an instantaneous HWS Oliver. If your going to have a mineralisation problem it would be with an aging, conventional, storage type system where the rust and crap tends to accumulate over time.

I fill my keggle from the electric storage unit in the shed. It saves some time.

I'm not concerned about impurities because there is 100 things I could improve before I start filtering water. I'm new to AG though.

Though I have never tried this but I do not think it will create any problem. It must taste fine.
