Notes:
I subbed a few of the grains with stuff I had in stock that was similar and needed to be used up. I subbed thte brown sugar with some invert I had left over from last year's
Forum Christmas Stout. Not used M47 before so will be interesting to see how that turns out.
I dont like using bottled water, but in trying to improve my brews I went with Avant, which was on offer at Tesco. This also has the lowest bicarbonate value at 122. I used 5ml CRS to reduce this to about 70ppm. Brewfather also advised adding a bit of gypsum, CaCl and salt (plus the standard pinch of campden). Oh - and I've never measured pH before, but I had some cheap pH paper and the mash was certainly in the pH5 ball park.
Fairly straight forward brew day, transferred hot to the FV and left overnight to cool. Ended up with 16 litres in FV as I sparged a little. Rehydrated the yeast an pitched this morning.

Edit to add: My interest was piqued and I've found out that Avant water comes from Camlica, Turkey. A fair amount of air (or road or sea) miles on that that then. When you consider
how much bottled water is sourced in the UK, it is a surprise that there is a need to bring anything in from anywhere outside of the UK.
