Hi all, I've completed one brew so far with one on its way, so I would say I'm still pretty new to brewing. Joined this site a couple of days ago and happy to share my journey so far. To date, I've only done two brews, one an extract brew kit, and my most current one I used grain and extract. My aim is to move to an all-grain process using a 5 gallon cooler for mashing BIAB, a 33l pot for the boil, a 23 litre fermentor and a 19l glass carboy. I use RO water that also adds calcium, magnesium and potassium. I'm plan on brewing only IPAs in the region of 4-5% ABV for now but will attempt other beers on occasion and maybe even a stout. My current thoughts or areas I'd like to address/improve are: I'm looking to add a chiller to the mix but not sure on the best size. My pot is about 33cm in diameter and I've seen some online that are 13/14cm. My first question is, should I go larger or is this sufficient? I'm considering moving to a Corny keg setup and moving away from bottles altogether. It does seem quite costly and being a novice, I'm hesitant to make the jump. I am however looking at refurbished kegs on eBay. Perhaps I'll make the move sooner rather than later. I'd like to become more familiar with the amount of nutrients in my water and adjust accordingly to build a water profile that suits the beer I'm making. I'm considering testing the water to find out the calcium, magnesium and potassium content but this is a lower priority.
