About the enzyme: Glucoamylase is often available at homebrew shops and from brewery suppliers. You might see it under the trade name Ultra-Ferm, sold by White Labs in packages as small as 10 milliliters (or as much as 10 liters for commercial breweries).
This isn’t a refined Czech or German lager; a long lagering phase isn’t necessary. It’s best to carbonate this beer on the higher side—about 2.8 volumes of CO2. Serve it nice and cold in bombers—rolled-up paper bag optional.
