Grist varies, although German Vienna malt is often the backbone of the grain bill, with some Munich malt, Pils malt, and possibly some crystal malt. All malt should derive from the finest quality two-row barley. Continental hops, especially noble varieties, are most authentic. Somewhat alkaline water (up to 300 PPM), with significant carbonate content is welcome. A decoction mash can help develop the rich malt profile.
