Another great English strain from Wyeast, released for a limited time as part of their Private Collection series! Thames Valley II ale yeast is a great yeast strain for use in the production of a wide variety of British beer styles. Highly flocculant, as well as highly attenuative, this yeast can produce beers that finish dry, with some stone fruit esters that create a wonderful complexity in the flavor profile. The yeast settles out well and can produce very clear beers. A diacetyl rest is recommended with this strain.
