Hey there, Here's my first IPA recipe which I plan to brew this weekend: https://www.brewersfriend.com/homebrew/recipe/view/983462/american-ipa I was wondering about the possibility of dry hopping but not sure what to use (i have the hops in the recipe plus some spare northern brewer and chinook). I have been messing around with Bru'n Water to get a decent water profile for the IPA, aiming for around 300ppm of sulphate to accent the hoppiness. I usually start with a pre-boil volume of around 10L and end up with 4-5ish litres (depending on the room temp really). I have added the additions that Bru'n water spouted out but the brewers friend recipe builder gave me crazy numbers like 800ppm sulphate. I have done some calculations myself and I think the numbers from Bru'n Water are correct but I'm doubting myself. I'll be using my tap water, it's very soft water so is essentially a blank slate. You'd think with a degree in Chemistry I'd be able to figure this out, but I just want to ensure that I'm not down a rabbit hole. Thank!
