DLS or GYPSUM

[fisherman]

Hi lads,
Imagine the CRS has lowered the alkilinity and is dead on, I am going to use 1 tsp in the dry goods and 1 tsp in the boil. Do I use DLS or GYPSUM. (PLEASE ADVISE) I am making a stanard 1040 Bitter.
Cheers

General consensus is to go with gypsum I believe. Certainly I shall be from here on. I teaspoon each in the mash and boil. This may help:-

Hi fisherman,

Gypsum will give you calcium and sulphate, whereas DLS is a mixture of calcium, magnesium and chloride salts. Brupaks designed DLS to work with CRS as a catch-all solution to high-alkalinity water. Unless you want to analyse your water and calculate the best treatment I would recommend DLS. Using gypsum alone increases the chances of having too much or too little of something important.

Cheers,
FC

DLS adds calcium, magnesium, sodium, sulfate and chloride....also Brupaks didn't 'design' it. It's a repackaged Murphy's product (as is CRS).

The main problem with DLS is that the chloride/sulfate ratio is predefined and may not be what you want. Personally I think using gypsum and/or calcium chloride is a much better idea as you can tailor your water as you need.

Having said that,if you're just chucking a teaspoon in to boost calcium either will do.

Thanks chris-x1,
My beers that where overdosed with dls or gypsum or CRS have matured now some are 8 weeks in the bottle are drinkable and time has taken some of the harshness out and are drinkable but not great. I did buy high alpha hops, far to bitter for me, now I have fuggles and goldings but still keeping the UBE down to 12 or 15. I did a brew without any water treatment I have dropped into a airlocked fermenter and will bottle in the morning. My next brew will be with CRS and 1tsp gypsum in dry goods and 1tsp in boil. Thanks for getting me mashing again from the alkilinity test for CRS dosage and other problems.
cheers

Steve Flack,
Same message to you as chris x1
Thanks

The DWB (DLS) we sell is designed to cover all ALE types, this does not include lager, stout porters and milds. For the latter we would certainly suggest using flake and gypsum separately to give a better balance. But as Chris-x1 said without a proper water analysis being done it is hard to tell. Saying that on a 25lt batch of beer it doesnt make that much difference apart from personal preference to the end product.
Feel free to send some water in!

Hello crookedeyeboy,
I would very much like to send you a water sample. It would be great to have someone check my water. Can you inform me how much water sample you require, and how you want it packaged and to where to send it to. I would be so happy.
Cheers

Hi,
I have posted off two 330ml bottles of my tap water to your laboratory this morning by first class post. I went to the supermrket bought new bottled water rinsed them out and filled with my tap water. Wil I be able to convert the readings from you to calculate how much of what e.g. water chemicals to adjust my water to a reasonable water for bitter or pale ale brewing.
Cheers
fisherman.

We will test the liquor in the lab then you will recieve a report recommending amounts based on the additions of DWB and AMS unless you require another specific recomendation. Please feel free to email me for further info once you have your results.

Thank you crookedeyeboy,
Looking forward to mashing. And cleaning out the drains with my old brew's.
Can't thank you enough
Cheers
