Re: Low mash pH

All things being the same with the next beer I would suggest backing off the acid amount you used to leave an extra 20-30ppm residual alkalinity (so aiming for 65-75ish). Also important to taste the beer and make notes on how you find it, both this and the revised version. Wow, 65-70 ish. Seems hig...

Low mash pH

Today's brew is 5kg Maris Otter, 400g crystal malt and 100g chocolate malt, mashed in 14l liquor. After adding CRS the mash liquor alkalinity was 44 ppm. The mash pH at about 20 minutes was 5.1. The lowest I've ever had. Hopefully not too low to make good beer though! Bearing in mind the amount of c...

Re: Graham's water treatment calculator

Thanks for that, Jim. Graham's notes are really helpful. I just suspect he made some sort of error when setting up the Burton formula. I always use the 'automatic' setting, so looking at what Graham has set up is for interest rather than anything else. Tomorrow's brew will have a 5:2 sulphate:chlori...

Graham's water treatment calculator

In Graham's calculator he has a 8:1 sulphate:chloride ratio for Burton pale ale.

Is this correct, please?

Thanks.

I'll double-check the settings this afternoon. Yes, Guy, definitely plugged into heating, not cooling.
Shame, would have been such an easy cure!!

Re: Help With Inkbird ITC-308 Controller

It should jut about handle a 2kW element. Worth checking you've been through the temperature setting process as described by Top Cat. The last step is important, or the Inkbird won't remember the temperature you've set. Secondly--forgive me for asking--you have got the element plugged into the heate...

Re: Help With Inkbird ITC-308 Controller

Where have you put the temperature sensor on the Inkbird and where's the thermometer you're using to check the temperature?

Re: Have I bought a duff pH probe?

Thanks for the info peeb Cracked it now, bearing in mind your helpful info. the ions have clearly all fallen out in my cheap ebay probe. Should never have left it in the upright position. In fact, I've just looked at the little bottle the probe is stored in, and it's absolutely stuffed full of ions....

The probes deteriorate about as quick unused as used. Bummer that isn't it! Stockpiling "spares" is a real no-no!
What is it that deteriorates? Isn't the solution they are kept in supposed to keep them working OK?

Re: Have I bought a duff pH probe?

It's been in the proper fluid since it arrived. Battery? Hadn't even crossed my mind. I'll go and check the one in the Voltcraft now. Thanks for the idea.

Have I bought a duff pH probe?

About a year ago I bought one of these as a spare in case the probe which came with the Voltcraft PH-100ATC meter needed replacing. The probe has just stayed in its packaging in a drawer since then. Today I thought it was time to unpack it and try calibrating it. The readings are totally unstable. C...

Re: make a wine kit stronger

Make up less than the suggested volume! If you make it to 4 litres instead of 4.5 litres you should end up with about 14%.
