Triple Double is a great Belgian yeast strain for use in making high gravity Belgian ales of all kinds! Specifically designed for dubbels, trippels and quads, this is actually a very nice strain to use on almost any Belgian beer. Relatively clean for a Belgian strain of yeast, it produces moderate esters with very little phenolics. It is a medium flocculating yeast, and though it may ferment slow at times, tends to clear well if given enough time to drop out of solution.
