It is a strong fermenter with medium to high flocculation and is an excellent choice for Märzen, Munich Helles, Dunkel, Bock, Doppelbock, Vienna Lager, Festbier, Schwarzbier, and other traditional German lagers.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThis strain produces slight sulfur and low diacetyl during fermentation. A diacetyl rest followed by proper cold conditioning is recommended for the cleanest finished beer. Compared with some of the cleaner and more neutral German lager strains, WLP838 tends to leave a little more malt character and complexity in the finished beer.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003e\u003cspan\u003eComparable strain references:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Omega Yeast OYL 109 German Lager II and Wyeast 2308 Munich Lager are direct comparable strain references. Omega OYL 109 is currently only offered in Probrew pitches and is not available as an Omega homebrew pack, making WLP838 an excellent homebrew option for brewers looking for this fermentation profile. Imperial Yeast L17 Harvest is another good Southern German lager option for similar beer styles, although it is not considered a direct strain equivalent.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eWLP838 Characteristics\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003e\u003cspan\u003eAttenuation:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e 68 to 76%\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003e\u003cspan\u003eFlocculation:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Medium to High\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003e\u003cspan\u003eAlcohol Tolerance:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e 5 to 10% ABV\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003e\u003cspan\u003eOptimum Fermentation Temperature:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e 50 to 55°F \/ 10 to 13°C\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003e\u003cspan\u003eSTA1:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Negative\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003e\u003cspan\u003eYeast Type:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Lager, Saccharomyces pastorianus\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003e\u003cspan\u003eCell Count:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Approximately 150 billion cells per PurePitch Next Generation package\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eRecommended Beer Styles\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eMärzen\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eOktoberfest\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eFestbier\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMunich Helles\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMunich Dunkel\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eBock\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDoppelbock\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eVienna Lager\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eGerman Pilsner\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eAmber Lager\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDark Lager\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSchwarzbier\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003ePale Lager\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eCream Ale\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan\u003eFermentation Notes\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eWLP838 is a strong lager fermenter that produces a malty finish with a balanced aroma.
