Having seen the interview with head brewer James of Verdant brewing on the Craft Beer Channel on YouTube I’ll be adjusting chloride upwards to pretty much the level of a stout to give me more body in the finished beer and dropping the sulfate. I’ll also be going with 80% of the minerals in the grist and 20% in the boil. I bought DWB as it was cheap but I'm regretting it, after lots of horrible maths I've worked out I'm going to need to add 8g to treat 26 litre and a further 2g of calcium. I don't think I'll be buying this one size fits all salts again and will probably look into get a proper water analyses rather than going by the water report from my area in the future. Where to get this at a reasonable price and who is accurate, no idea. also ph is a little high, 5.5 would probably work better so a little phosphoric or lactic acid is needed.

Notes

about the grain bill, I used Crisp malts Maris Otter extra pale malt not ‘finest’ and the OG was 1.045 not 1.049

oxidation was a little issue cause of my setup, I'm using a brew bucket, siphoning into my klastein mashtun with the priming sugar and then bottling with a cane. I'll try adding a little sodium metabisulfate to help drive out some of that oxygen next time.
