Hi,
On the weekend made a Kolsch and used the German Ale yeast strain from Wyeast for the fermentation. Details are as follows;
Recipe Specifications
--------------------------
Batch Size (fermenter): 21.00 l
OG: 1.050 SG
Color: 7.9 EBC
IBU: 23.3 IBUs
Boil Time: 90 Minutes
Ingredients:
------------
Amt Name Type # %/IBU
2.45 kg Kolsch (5.9 EBC) Grain 1 50.0 %
1.85 kg Pilsner (2 Row) Ger (3.9 EBC) Grain 2 37.8 %
0.50 kg Wheat Malt, Ger (3.9 EBC) Grain 3 10.2 %
0.10 kg Acid Malt (5.9 EBC) Grain 4 2.0 %
28.00 g Hallertauer Mittelfrueh [8.00 %] - Boil Hop 5 23.3 IBUs
1.0 pkg German Ale (Wyeast Labs #1007) [124.21 m Yeast 6 -
Mash Schedule: Temperature Mash, 2 Step, Light Body
I made a 1.1 lt starter with a very fresh yeast packet (dated June 13)( beersmith asked for 202 billion cells, I made 245 with a 1.1 lt starter) and pitched at 15c into the 21ltres. I checked the gravity at day 2 of ferment and got 1028, day 3 which was today i got 1020 so i went ahead and racked it to secondary
With a fast primary and only about 5-6 gravity points till expected FG this has fermented way faster than anticipated. My understanding of the Kolsch at 15c would take 7-10days primary and about 14 days secondary.
I have checked my calc and equipment and was wondering if anyone else had experienced a faster ferment from this yeast?
