Re: Boiling to lower alkalinity

Sorry, just read back through the pages and got my answer. So I would just minus 40% off my original Calcium content to achieve the new calcium content after boiling? Yes, if the original calcium content was known. When boiling, any reduction in alkalinity will of that bonded to calcium. After boil...

Re: Boiling to lower alkalinity

Haha, I only use it for this particular style of beer and it does work really well, the only problem I can get with it is that it doesn't compact to much when it settles and ends up tasting nasty if too much get into my glass Agreed, it certainly doesn't want to quickly flocculate, yet it seems to ...

Re: Boiling to lower alkalinity

Yes, Dextrin malt would do that. I've used it mainly to add body and flavour to milds, but presently have none in stock.

Only once used US05, to record that brew to be a waste of good malt. I've often read it described as a clean yeast, so must presume I like my beers dirty.

Re: Boiling to lower alkalinity

Nothing there I've not used, just somewhat surprised to see rice and dextrin malt in the same recipe. I use rice to reduce flavour, body and nitrogen content, while dextrin malt does the opposite. Never considered what their combined influence would be.

What yeast did you pitch?

Re: Boiling to lower alkalinity

A mean value for sodium is given as 23.3 ppm. The rest are as you give, Guy, and your given alkalinity is as CaCO3. The figure I use for the strength of CRS suggest that 0.69 ml in 1 litre would reduce alkalinity from 152 to 26 ppm as CaCO3. I don't understand how the taste of sulphate and chloride ...

Re: Boiling to lower alkalinity

But would a TDS just show me the amount of total dissolved solids or would it help more with knowing the Calcium content? It would do both Matt, not perfectly accurate, but good enough for our purposes. It would let you know how consistent your water is or is not. It is highly likely if the TDS of ...

Re: Boiling to lower alkalinity

I've not used a Salifert kit to determine calcium. Reading these instructions suggest 8 drops, but I wouldn't know what is correct. It is noticeable that the kit is designed to cater for much higher levels of calcium than in your water, although it does cover that range too. My water's mineral conte...

Re: Boiling to lower alkalinity

So, I have an average hardness of 244ppm as CaC03 and and average Alkalinity 152ppm as CaCo3, which is the important factor in that report? When I measure the Alkalinity with Salifert I take the dKH measurements and Multiply them by 17.85 to get my Alkalinity, I presume as CaCO3 but maybe that is w...

Re: Boiling to lower alkalinity

Sadly, high nitrate levels are commonplace these days, its continuous increase from artificial fertilisers in this area is happening despite a constant reduction in the amount of land used for agriculture. You likely have an advantage over me on digging into history, being more than halfway into my ...

Re: Boiling to lower alkalinity

Thanks for your help here. The 82ppm (corrected to 89ppm by Matt) would be roughly from the time of the report, might that have changed? Maybe I should add X amount of Calcium to X amount of distilled water to determine if the kit is accurate or not? From that report, your water would appear to be ...

Re: Boiling to lower alkalinity

Yes, 120 ppm is probably the highest level of calcium I've seen in a water analysis in Great Britain. That level is likely the upper limit of commercial water supplies in the British Isles. I've measured higher calcium levels, but not from a source likely to be used for a domestic water supply. As a...

Re: Boiling to lower alkalinity

Also just tested Calcium levels and I'm at 120ppm, retested Alkalinity and that's settles at 73ppm. If your water has 120 ppm calcium after removing 80 ppm alkalinity, then you have none of the concerns I raised. That also suggests the initial calcium content was in excess of 150 ppm, an unusually ...

Re: Boiling to lower alkalinity

Yes Matt, less minerality, less reduction of unwanted compounds, less British, less taste, less satisfaction. 40% of the reduction in alkalinity is a reduction in calcium. 40% less protection for the essential enzymes from premature destruction. 40% less deposit of phosphates and oxalates as hot bre...
