I’ve been doing a lot of yeast reading recently, mainly because I’ve decided I want to brew a trappist beer for the Stud and his Duchess’ wedding, and am planning on harvesting some yeast from the bottle.
But in the time, I’ve read a lot of stuff yeast generally. It seems most people suggest making up a starter, even with liquid yeasts. While lot of yeasts will probably adapt, you want to get fermentation going as quickly as possible, to provide protection against infection.
As you’ll see here, to be most efficient, you’d need to pitch 1.8 yeast vials. Best to get it up and running to save you wasting money. Whatever amount of wort you’re preparing, a strength of 1g Dry Malt Extract (DME) to around 10 ml water.
I’ve made 3L wort up (i.e. 300g DME), and pitched the yeast. Half of this will go in to the more golden of my next brews, and the rest of the yeast will be kept for one over the next week.
