Hi all, I've been lurking here for a while now attempting to hoover up all the accumulated knowledge before I attempted my first stove top all grain BIAB but I've hit a brick wall and need a little help! The background to all this was my better half thinking it would be a good idea to buy me an all grain Brooklyn Brew Shop Punk IPA kit for my Birthday this summer. I hadn't made home brew for 30 years and she thought I'd enjoy doing it again. I did... and then some. I quickly sought out a homebrew shop and bought a couple of premium kits. Before long I had a brew fridge and homemade kegarator in the shed! After good results and half a dozen kits later I toyed with trying extract brewing but realised without much extra outlay I could scale down all grain recipes from the books I'd bought from a member here (who'd put them on eBay). I've actually bought the ingredients for an Old Peculier clone via The Malt Miller. I bought enough for 19 litre's and intend to halve everything and brew in a bag in my 17 litre stockpot. I should end up with 9.5 litres of beer so hopefully 18 x 500ml bottles. I can then brew the remaining ingredients at a later date making any changes I feel necessary. Does this sound OK? Anyway, brewday is Saturday as family are all out and I'll have the kitchen to myself. I thought I'd keep it simple by just rinsing mashed grains over an FV (though colander) with pre-heated sparge water and then adding to the wort before boiling with hops at appropriate timings. I then intend to cool in an ice bath in the sink and pitch re-hydrated S-04 before moving to the brew fridge. Hopefully that all sounds OK so far for a first attempt but any advice gratefully received. Now to my concern. Water treatment. I know people say not to over think it especially at this point in my "new" hobby but I thought i'd try to get the basics right. Haven't got time to get a profile from my water supplier so have bought Tesco's Ashbeck mineral water and wanted to enter the composition of this into the recommended calculator on Brewer's Friend but having done that I'm none the wiser about what steps I should take next. I was hoping someone could look at the profile below and advise me or perhaps share a profile of Ashbeck they've already made and tell me what additions I should make. https://www.brewersfriend.com/mash-chemistry-and-brewing-water-calculator/?id=1NX2H6H Many thanks in advance.
