So I am planning on brewing a tank 7 Clone but have some issue with ferment temp. Still very mild weather here in Colorado and my basement is parked at 60F. My though is make a starter with WLP565 let it go for 4-5 days then pour off spent wort and add new wort and pitch with a more aggressive strain say Belle Saison or a champagne yeast and let that go for another several days. Will i get benefit from both yeasts? In other words full attenuated at a somewhat cooler temp then ideal.
