Yes true they are. My dry hopping is scheduled at day 0 when transferring and again at day 3 during active fermentation so that the yeast/CO2 scrub and push out what oxygen gets in during the second dry hopping.
New here and looking to get into brewing. I've done a lot of research and want to jump straight into all grain BIAB. Already using Brewers Friend to build a few recipes. First attempt will be a DDH New England Hazy IPA.
