My next batch is a high gravity wit. The calculator says my smack pack is not enough and I need to grow more yeast. It says 2L of starter is enough. Question 1: as I watch videos, I see a lot of people making smaller starters, and each day increase the size of it until they have what they need. Is this necessary? Or can I simply start with 2L of water and the appropriate amount of DME and call it a day? Question 2: if I’m not trying to stick to matching a particular style, is there any reason not to start with the starter wort to finish filling to 5 gallons? Otherwise, I need to buy another bag of DME. Thanks for your feedback.
