About to do my second brew, a NEIPA. For this one I got the classic Wyeast London A3 1318 and I am planning to do a starter. The yeast has January 25 date on it, so I guest it should be about 55% viable. This is my first time working with liquid yeast and I want to build a starter. I don't have a stir plate, but I plan to use a blender on the lowest setting. It has a non-stepped speed controller, so I can run it on a very low speed, lower than "1" in most blenders, thus I think that if I succeed sanitizing it, then I should be fine. What pitch rate do you think I should go for, considering I am most likely going to build a 20L (5gal) 1.06 wort for it to ferment? I would like a slight underpitch to create some more intense fruity ester profile. My starter will be (unless someone proposed something better) 1L with 100g extra light DME. Should I leave it in the starter for 2 days, or will 1 suffice?
