K1V-1116 shares much of EC-1118's reputation for reliability and hardiness, with one particularly useful distinguishing trait: genuine cold tolerance, fermenting effectively down toward the bottom of its 50-86°F range in conditions that would slow or stress many other strains, wine or beer yeast alike.
A cider default for a reason
Clean, fast fermentation with real cold tolerance makes K1V-1116 a common default for traditional cider, particularly in regions or seasons where fermentation temperature naturally runs cooler than an indoor ale fermentation would — the strain doesn't need active warming to perform well, a genuine practical advantage over a strain that reads sluggish or produces off-flavours below a certain temperature threshold.
Reliably dry, even at real strength
K1V-1116 publishes an aggressive 88-96% attenuation range. Run a 1.090 must through the midpoint of that range and the result lands close to 1.0072 — roughly 10.9% ABV by the simple formula, among the driest, most dependably high-attenuating results on this site. The ABV and attenuation calculator confirms what a specific batch's own measured gravities actually work out to.
A rescue strain, much like EC-1118
K1V-1116's robustness and reliability make it a reasonable alternative to EC-1118 for restarting a stuck fermentation, though it lacks EC-1118's specific killer-yeast factor — it competes well against a struggling fermentation environment through sheer vigour and tolerance rather than actively suppressing a rival strain the way EC-1118's genetic trait does.
Flavour profile
K1V-1116 reads clean and relatively neutral, closer to EC-1118's restrained character than to 71B's fruitier, malic-acid-softening profile — a real consideration for a cider maker deciding between the two: K1V-1116 for a clean, crisp, apple-forward result, 71B where a rounder, less tart, more overtly fruity cider is the goal instead.
Flocculation
Low flocculation means K1V-1116 doesn't clear especially quickly on its own, similar to most of the wine-derived strains covered here — a genuine trade-off against its speed and reliability during active fermentation, since clarity still generally requires extended conditioning or fining afterward.
A note on wild-fermentation risk with real apples
Traditional cider making sometimes starts from fresh-pressed juice carrying wild yeast and bacteria rather than a sterilised must, and K1V-1116's vigour and cold tolerance give it a real practical edge at establishing dominance over whatever wild population came in with the fruit — not a guarantee against contamination, but a genuine advantage over a slower or more delicate strain in that specific scenario, where getting a strong, healthy fermentation established quickly matters for outcompeting anything unwanted already present in the juice.
Its clearest home
Cider is K1V-1116's clearest home, alongside mead and fast, clean fermentations more broadly where a maker wants speed and reliability without the specific aromatic-softening or aromatic-preserving traits 71B or D47 bring to the table instead.
Choosing among the four Lalvin strains covered here
Between EC-1118, 71B, D47 and K1V-1116, the real decision usually comes down to what the recipe needs most: EC-1118 or K1V-1116 for raw reliability and high alcohol tolerance, 71B for softening a tart, high-acid fruit, and D47 for preserving delicate aromatics and adding body through glycerol. None of the four is a universally "best" mead or cider yeast — each earns its place by solving a specific problem the others don't.
