Don't know anything about that beer but if it is a Munich Helles you could give this a try. This is my favorite style of beer, I could drink liters of Munich Helles all day and all night long...
Munich Helles (PM)
OG 1.050, FG 1.013, 4.8% ABV, 18 IBU
3.5# Extra Light DME or Pilsner DME (if you can find it)
2# German Pilsner
8oz Flaked Wheat
1oz Tettnang, Tradition, or Hallertau (4-5% AA)
Combine crushed grains in a grain bag and drop into 1 gallon of filtered tap water or bottled spring water (not softened water!) heated to 166*F. Temp should stabilize around 154*F. Remove pot from burner and wrap in a blanket. Let mash for 60 minutes. Then bring 1 additional filtered gallon of water to 175*F in a second pot. Remove grain bag and drop into second pot. Let soak for 5 minutes, drain, and discard grains. Move contents of second pot to first pot and top up to 2.5 gallons. Add the hops, bring to a boil, and boil for 75 minutes. Carefully add extract to avoid scorching and add one Whirlfloc tablet. Continue boil for 15 additional minutes. Chill quickly in a water bath or using an immersion chiller. Fast chilling is important for this style to ensure you do not have chill haze. Since this is a light brew it is also a good idea to use a strainer to strain out hops and break material to keep them out of the fermenter. Top up to 5 gallons in the fermenter with bottled water of your choice.
As far as fermentation you have a couple of choices. You can lager with a lager yeast like WLP830, or you can use a lot of clean ale yeast and ferment it cool. Two packages of US-05 at 64*F will yield a very clean beer. Or you can use a 2L starter of WY1007 German Ale yeast at 62*F. Or you can do what I'm going to do next time and pitch a package of German Ale yeast plus a package of US-05 dry ale yeast making a yeast blend. Temperature control during the first few days of fermentation will be key to getting this beer to come out to style. I use a water bath for my ales and change the ice 2x daily. I have found that 3# of ice twice a day will keep the temps 60-64*F which is ideal for a squeaky clean ale.
EDIT: added recipe to my drop down.
