is a Germany spring brewing barley variety that was very popular in the 1990s, especially in southern and eastern Germany. It was bred by Saatzucht Josef Breun GmbH & Co KG of Herzogenaurach near Nuremberg in Bavaria and was registered with the Bundessortenamt (the German government’s crop-licensing agency) in 1991. In its heyday, many brewers favored malted Sissi as a pilsner-type base malt because of its good disastatic power and its ability to produce full- bodied, malt-accented beers with good head retention. Sissi had several agronomic drawbacks, however. Its yield per hectare was only average and it was fairly susceptible to mildew (Erysiphe graminis). In the brewhouse, too, its extract yield was only average and it is now easily surpassed in extract values by more recently bred brewing barley varieties. Today, therefore, Sissi has disappeared entirely both from the official list of recommended barley varieties maintained by the Bundessortenamt and from the catalogs of commercial barley breeders and traders. However, Sissi is still planted in very limited quantities, perhaps only a few thousand tons per year, almost exclusively in Bavaria, and usually on a special-order basis just for small brewers who have formulated their recipes specifically for this variety.
