Weyermann Bohemian Pilsner Malt is a lager-style base malt produced from Czech barley varieties Bojo and Tolar. The Czech-grown grain is processed specifically for "Bohemian" characteristics to impart a full body, golden-blond color, and complex maltiness to the finished brew. It's perfect for authentic Bohemian pilsners and Belgian ales, but is well-suited to any beer style that requires a solid malt presence.
Going for a classic "young" grisette here. According to Dave Janssen, "...we can also assume that grisettes were generally served younger. This would mean that the hop character would be more forward than an aged beer of a similar recipe and there would not be much time for bacteria (and in addition wild yeast) development, lending support to the Farmhouse Ales information that grisettes were crisp from hop character and without acidity." So, going from this, a non-saison-like strain may do the trick. Out of personal preference, the Gnome yeast selection seemed to make sense, but only if fermentation temperatures are kept in check... ~low 60s. Too warm, lots of phenols would be thrown by fermentation.
