This style depends on pitching a lot of healthy yeast cells. As with hops, however, the particular strain is not hugely important. What is important is that esters, aromatic alcohols and other flavor compounds associated with yeast’s respiration and reproduction phases are subdued. This can be accomplished by choosing a yeast strain that is known to be relatively “neutral” in flavor impact. It can also be accomplished by pitching a large volume of any ale strain and fermenting at a cooler-than-usual temperature.
add yeast nutrient. Perhaps soften the water slightly by adding NaHCO3.
May also need daily agitation of fermenter.
