Ferment in primary for 1 week. After 1 week transfer to a keg and perform diacetyl rest for 2 days. Begin lagering.
Refer to Bierstadt course for mash temps and times. This beer was very thin and could use some better head retention.
Something like this should get close -
2.0 gal 140 deg F water to hit 133 deg F for protein rest (10 min)
2.0 gal 170 deg F water to hit 145 deg F for beta amylase (30-40 min)
2.0 gal boiling water to hit 166 deg F for alpha/dextrinization (30-45 min) add 1/2 gal at a time until mash hits 166, measure volume
follow with sparge
Hallertau Blanc has significantly more AA than traditional noble hops (10 AA). Consider more hops @60min or more additions throughout the boil if using a more traditional variant. Tettnanger, Spalt, Saaz and Hersbrucker would surely all be great.
