Formerly known as WLP862 Cry Havoc, this signature strain has since been renamed to honor its creator, Charlie Papazian. Fist Bump has the ability to ferment at both ale and lager temperatures allowing the brewer to produce diverse beer styles. The recipes in both Papazian's books, The Complete Joy of Homebrewing and The Homebrewers Companion, were originally developed and brewed with this yeast. Papazian had "Cry Havoc" in his yeast stable since 1983.

When fermented at ale temperatures, the yeast produces fruity esters reminiscent of berries and apples. Hop character comes through well with hop accented beers. Diacetyl production will be very low when proper fermentation techniques  are used.

When fermented at lager temperatures, esters are low in high gravity beers and negligible in other beers. Pleasant baked bread-like yeast aroma is often perceived in malt accented lagers. Slightly extended fermentation times may be experienced compared to other lagers. Some fermentation circumstances may produce sulfur aroma compounds, but these will usually dissipate with time. Good yeast for bottle conditioning.

PurePitch® Next Generation—now with more yeast, get a foolproof fermentation without a starter! Just twist the cap & pitch!

Why PurePitch Next Gen versus other options?
Typically yeast manufacturers use a range for how many yeast cells are going into each package. This can vary widely, especially from strain to strain.  Next Gen offers a far more precise cell count across all strains allowing you to use the Whitelabs exclusive pitch calculator. Simply scan the barcode on the back of each package to be taken to their online calculator. Enter the volume, strength, and pitching temperature of the wort you are fermenting and the calculator tells you exactly how much yeast to pitch. You will be fermenting like a professional brewer, using the same concentration of yeast every time and enjoying more consistent results.  Don't need a full package? Put the lid back on and store in the refrigerator for your next batch. Whitelabs has also increased the viability (the number of living cells in the package) over the shelf life of the yeast. Next Gen strains are grown in their unique, small-batch reactors to assure freshness and then packaged in a special film that allows for off-gassing, assuring that their viability is absolutely industry leading.

For best results we always recommend ordering an ice pack with your liquid yeast.

Please Note: When choosing an ice pack option beware that the liquid yeast will not arrive cold even when shipped together. Ice packs and insulated mailing options are designed to keep the yeast colder for longer during shipment, but they will not ensure that your yeast arrives cold. We will not replace liquid yeast that arrives warm. During warmer months we strongly recommend you choose dry yeast.
