Description
The clean kveik: it stays remarkably neutral across its whole temperature range, so it can turn around porters, stouts, English IPAs, ambers and light ales quickly without an ester signature. Push it warm and soft pear and apple notes appear, most obvious in lightly hopped beers. It dislikes big wort and should not be asked to work above about 18°P.
