https://www.brewersfriend.com/homebrew/recipe/view/305918/cal-common I'm set to brew this today. But I just noticed that the recipe does not distinguish the amount of strike water vs sparge water. I don't understand if the recipe is saying that sparging is not intended to be done after the first drain to brew kettle. Is that ever the case? It just gives the starting mash thickness (2.95 qt/lb) and says vorlauf as necessary. Is that it? No sparge step?
