Re: Rust in the very bottom of my cornelius kegs

Pitting corrosion on stainless is possible but requires extreme conditions which I would very much doubt would have occured with a corny keg on beer. The thing to avoid on stainless is wire wool which can leave fragments of steel which will corrode the stainless. Alkaline cleaners will not be very e...

Re: Muntons gold pilsner 2 can kit

This is a pretty good kit and one that I would use. It is good for learning the how to make a pilsner. I tend to make my pilsners in the winter months and age them for months stored in a cold shed. To get it going I made a strong starter with 220g honey and 2.5 g Fermaid K using the yeast sachet, 24...

Re: Temperature of beer when doing water treatment

Chastuck, Thanks for the info. I delved a little deeper. https://www.fishkeeping.co.uk/modules/newbb/viewtopic.php?post_id=317939 Quite a few water co's are now using chloramination and worst of all now my own supplier but I have yet to see any evidence in my supply. It looks as if this could become...

Re: Grainfather pump issues

Pee Bee, the fact that you can freely buy oxi cleaners should tell you something. It is not that scary by any means. If it was you certainly would not be able to buy it at Tescos et al. It is a convenient way of handling hydrogen peroxide, generating it in situ rather than having a liquid, that in h...

Re: Temperature of beer when doing water treatment

Dave, Thanks for clairifying whay you used a campden tablet. Like Eric, I do not bother with sulphites but I can fully understand why Americans are a little paranoid as their municipal water reeks of chlorine, possibly chloramines as tmany utilities in the US use chloramines instead of chlorine. You...

Re: Chemsan?

I do not wish to get into a slanging match but here is pertinent information of the relative safety of Chemsan and a caustic food cleanser such as Amphoclen S, which is used in dairies, breweries and cellars. This is a product that I use. I would stress, as Mr McM does, that nothing betters good man...

Re: Chemsan?

Here we go again. It is perhaps worth discussing sterilastion, disinfection/ sanitisation and the so called no-rinse cleaners. At our level we cannot achieve sterilisation but we can disinfect, the best products, in my humble opinion being oxidising materials such as chlorine and chlorine release ag...

Re: Temperature of beer when doing water treatment

I am a little intrigued by this post. Firstly I would agree with Eric, very sound advice. But, what are you brewing? All grain, brew in a bag(BIB), kit? I am not quite sure. Why do you think that you need a campden tablet (sodium metabisulphite - which is an oxygen scavenger). If you are all grain o...

Re: Cornelius keg for real ale

I think that you will find some useful charts on carbonation at the top of the post for dispensing from Jim which gives some details on the concentration of carbon dioxide in g/L. You will not only need to replace the volume of liquid drawn off with carbon dioxide but also provide a driving force to...

Re: Boiling to lower alkalinity

Eric, I would agree that the other anions (chloride and sulpahte) will influence the tolerable alkalinity of the water. I was surprised by the concentration of nitrate and sulphate in the analysis of Matt's water. Nitrate is not that common and is often indicative of agricultural run -off. It tends ...

Re: Boiling to lower alkalinity

Matt, I follow Eric's observation in that you calcium is high, or even super high. Are you reporting as Ca mg/L or CaCO3 mg/L. The hardest water I ever came across was in Swindon where it came in at 120 mg/L as Ca. I sold a water softener to the sports centre and they had avalanche of foam coming ou...

Re: Lager and pressure fermentation questions/experiment

In theory, and in my opinion , no. But it very much depends on the size and type of airlock connection. An ale, with a vigourous fermentation could produce so much krausen that it might overwelm the airlock/ blow off cane. What is crtical is the sizing of the airlock and it connection. The biggest r...

Re: newbie help please

Sparky, Patience is a virtue. One thing I have learned it that one needs to be patient. I like to give my ales at least six weeks prior to drinking and much longer for pils, which are much more sensitive. Two things I would not do. If you have an indirect hot water cylinder your hot water could well...

Re: Bicarbonate HC03

I will try and keep this simple. To all intents, calcium carbonate is barely soluble in water. Very roughly 20 mg/L will dissolve in water as the carbonate. In the presence of carbon dioxide more calcium carbonate will dissolve as calcium bicarbonate is formed, which is soluble in the hundreds of mg...
