Re: Phosphoric and ascorbic acid for alkalinity reduction.

I am still digesting killer's responce. There are more ions than just "brewers ions". And precipitated calcium although not in suspension would still be in the liquor tank. Cheers, ARNWD. I hope that I'm not putting you off... I wouldn't overthink it at this point - just use the calculator to get t...

Re: Phosphoric and ascorbic acid for alkalinity reduction.

You will always have anion cation balance in the water. Every positive charge will have a negative charge associated with it. The reason Chloride and Sulfate increase when you add CRS is because CRS is a mixture of Hydrochloric and Sulfuric acids. When these acids are in water they form Chloride (an...

Re: Dry hopping, terminology confusion.

Wet hopping is just a fashionable term. It’s to sell the idea of the ultimate freshest hops/ IPA possible. It’s also sometimes called green hopping – I think there is even a festival in Kent for this. Dry hopping has expanded to way beyond what it once was both in how it’s done and the quantites – I...

Re: Do i need to add sugar to a corny keg once fermentation is complete to get some carbonation going prior to kegging?

You can carbonate your beer in a Corny keg a couple of ways - using sugar (either residual gravity points or added, sugar or using a cylinder of CO2 hooked up to your Corny. But you need to very careful if you use sugar. Corny kegs usually seal under pressure - and that could require 10 psi or less ...

Re: First brew (Courage Directors) and question

Well done on your first brew and welcome to Jims. If you want to bottle then you don't really care about an airlock on your second vessel. The idea, as you've said, is that once your beer has finished its primary fermentation (all the sugars have been turned to alcohol) you prime it with a specific ...

Re: Water treatment at it simplest

Welcome from a longtime brewer but young(ish) chemist. Water chemistry is a real can of worms subject as there are a number of divided opinions. There is a lot of (mis)information out there. Some people get away with minimal (or even no) treatment, others, like myself need to reduce alkalinity subst...

Re: Ro or tap

I have come across a number of breweries brewing Russian Imperial Stouts using a double mash system. Two of these breweries knew that they needed an alkalinity of at least 300 ppm for the first mash. In attempting to raise their liquor alkalinity from ~200 ppm to 300 ppm using slaked lime and follo...

Re: Ro or tap

Reducing the alkalinity of highly alkaline source water via slaked lime treatment, and lowering mash pH via the same are two distinctly different subjects. In the mash calcium hydroxide both raises and lowers mash pH simultaneously. The Ca++ calcium ion component complexes with malt phosphates to l...

Re: Ro or tap

Only one thing to add to the excellent advice above; Graham Wheeler's water treatment calculator on here is excellent. Takes a bit of practice to get used to it, but it does everything you need. Happy liquoring! Guy Indeed it is excellent, and there is undeniably nothing else like it, but it has a ...

Re: Low mash pH

… don't agree with your assertion that you can't reduce alkalinity using slaked lime/calcium hydroxide, but equally I don't see the point in arguing about it as it's an odd technique that is rarely used.

Re: Low mash pH

Half the problem (in my mind, at least) is that there are so many variables at play that it's very hard to determine what is having an effect. And whilst water is the largest component of beer, as long as it's not "utterly wrong", I'm not sure my tastebuds are good enough for me to be able to deter...

Re: Low mash pH

Bit confused, Cobnut! You support PeeBee in his thought that home brewers shouldn't have to worry about water treatment. Then you say you brewed beers which went down the drain until you treated your water with CRS. Now you win medals in national competitions. Firstly, congrats on the medals. But, ...
