Water Additions.......When?

Postby Cornish Knocker » Wed Sep 12, 2018 21:21

My last few brew days I've added the necessary water additions, gypsum, calcium chloride etc etc., to the strike water (I brew in a Grainfather) and then dough in. I'm now questioning myself whether this isn't the best time to do it and perhaps add them after I've doughed in might be better. Any thoughts?

Thanks

Hi,
I would treat my water with Campden tabs as the HLT fills up.
Treat the water for alkalinity with your acid(s) of choice.
Gypsum is difficult to dissolve and dissolves better in cold water than in hot water.
Add the gypsum (calcium sulphate) to the cold water in the HLT and dissolve.
Next add the calcium chloride and dissolve.
The water is now ready to be heated to strike temp.
I personally think it is better to add all your salts to your water and treat for alkalinity before you dough in.
As you have a recirculation system, you can probably add all your salts (chlorides and sulphates) you need, mixed into your grain.
High calcium levels makes gypsum difficult to dissolve.

The information provided by Murphys regarding water treatment advises to add salts to the mash. That’s how we do it at work. The only thing added to the HLT is acids for reducing alkalinity.

Thanks guys for the replies, much appreciated. I use reverse osmosis water, so I'm starting from scratch regarding water additions.

@Furbar, you're right if it aint broke etc etc. My last few beers I've made once I got my around the water additions etc have been very good. Now I feel I sort of understand water I want to try and get everything perfect.

Cheers all.

My biggest beef with American beers is that everything has that citrus-hop taste and aroma, regardless of style. I’ve had bitters and stouts with c-hops and it’s just awful.

The insistence on using reverse osmosis water, then building the mineral profile back up seems weird to me. Why not find out what is in your tap water, then go from there. I do that at work and we have great beers.

At home I use bottled water for pale beers and tap water for darker beers - that works great for me as it’s repeatable. The bottled water is pretty much good to go ‘as is’ with only minimal tweaks to the mineral content, so it’s convenient.

Every now and then the local water board sends some right old chlorinated rubbish down the pipes. Thats the only reason I can see to use RO however I'm to tight to buy it and I don't like the throwing away plastic packaging bit. I always smell the water now as I fill my hlt.

A campden tablet in the vessel and then put the water on top will deal with any chlorine issues

As for Murphys, I don't like the one size fits all approach they advocate ... Recommendations are OK, but only apply to a limited range of 'English' Beers. Also the recommendations haven't changed in 25 years, despite the increase in knowledge and techniques at our fingertips.They are biased to the products they sell, fair enough, but what if your water is not standard. you can treat a wider range of waters better using individual acids (Hydrochloric and sulphuric rather than AMS/CRS), and individual salts (calcium chloride and calcium sulphate rather than DWB / DLS). If you like a sulphate forward liquor, and that's what the Burton brewers had, then fine, if you want to go chloride forward, like Sam Smiths (Landlord anyone) then you are stuffed.

For one vessel brewing, add your campden tablet and start filling, after you have around 5L in it, add 2/3 of your acid, once you have 15L in there, add your salts. calcium sulphate is soluble!!! it is a myth (almost) that it is hard to dissolve!!! the solubility limit for calcium sulphate/gypsum is around 2.3g/l, so if you are trying to dissolve 20g in 1 litre of water you are going to fail, but dissolve the same amount in 15 to 20 litres and it happens with no issues. If you already have a high level of calcium in your liquor then you may still experience issues, but you probably won't be trying to add a huge amount of calcium anyway (or shouldn't). Still it's a good practice to add your gypsum first, and then to add any calcium chloride afterwards. Once you have all the water in the vessel measure your alkalinity again, and add the final amount of acid to bring the alkalinity where you want it to be.

The advice to add it to the mash is somewhat out of date, as there is the belief that it required the 'acids' released from the malt to help it dissolve ... it dissolves quite happily, I know a commercial brewery that adds the Acids/salts to the HLT while bringing it back up to temp first thing in the morning as they are recircing it ... then mash and sparge. It's the first 15 to 20 minutes that the mash pH is established properly, if you don't have sufficient salts dissolved at that time the pH will be all over the place

Just my thoughts ;)

Some great info in this thread. I live in Beccles suffolk and the water is hard as hell. I am not too bothered about that as it is treatable. What I dont like is the honking plastic taste thats in it. I find this common in norfolk and suffolk. How do I get rid of that?

I've just started using RO water, first brew with it is fermenting, I'm sure it's going to be OK :thumb:

After years of using tap water at 260ppm alkilinity, AMS, campden tablets, and then salt additions to get the balance right I caved in and just bought the filter, now I can start from scratch and just add salts, it makes life alot easier.

Reading around, seems there is some consensus to adding all the salts to the strike water before doughing in and leaving the sparge as Ph'd RO (below 6.0), I didn't do that this time around and just treated it all, using a small amount of Phosphoric in the mash to get to get Ph down a point to 5.4.

Gypsum readily dissolves in 25C water, as does Calcium Chloride. I didn't add any magnesium (epson salts) as I've read in a few places that the grain adds enough for the mash.

I'd rather have a bottle in front of me, than a frontal lobotomy :D
