I'm brewing a pre-pro lager Sunday (first lager). I made a starter about a week ago b/c I knew I wouldn't have time during the week. Well a when I did the starter I was assuming 1.045 OG on 5 gal which mr malty said needs a 2.1L starter on a stir plate... I did a 2L. It's been crashing in the fridge about a week. I brewed a porter last weekend and being my 3rd all grain I have apparently improved, my gravity was up to ~75% from 70%. So I'm thinking I'm going to end up with more like 5.5 gal of 1.045 lager.
Mr Malty says 2.67L starter for this. Now remember this is an American Lager so it's not gonna cover esters well. Do I need to step up this 2L starter? I've heard you should step up bigger than your last volume, but I don't have the means to go bigger than 2L plus I'd be overpitching if I did that.
