I brewed a monster RIS today and pitched with 1968. Gravity at pitching was 1.101, and I still haven't added the 15% sugar I was planning (2.36#).
I'm planning on pitching a pack of S-05 along with the sugar to help with attenuation but I'm not sure if I should just rehydrate and pitch, or actually get it active in a small starter.
I realize that making a starter is usually not recommended with dry yeast but we're usually giving out that advice when it's the first pitch. Will the yeast be ready to ferment if I plunk them in a wort that already has alcohol and no oxygen if they're only rehydrated in water?
