This is a summary of commercially available kveik cultures. See the above descriptions, the [http://www.garshol.priv.no/download/farmhouse/kveik.html kveik registry], and the vendor's website for more information about the cultures. Most are single strain isolates, while some contain multiple strains or the native "unpurified" mixed cultures (this will be denoted in the Notes column). Note that strain information can be misleading because kveik cultures make talking about individual strains difficult due to the strains being closely related yet diverse. Richard Preiss describes kveik cultures as being "heterogenous but related communities", meaning that there can be a lot of genetic overlap between subpopulations in a kveik culture and where one strain begins and another ends has yet to be defined (see [[Kveik#Recent_Yeast_Lab_Analysis_and_Commercial_Availability|Recent Lab Analysis]] above) <ref name="preiss_strains" />. Commercially available non-kveik landrace farmhouse yeast are listed on the [[Landrace Yeast]] page.
