##### Hi... How many packs of 34/70 for 12 gallons of 1.050 wort?
« on: August 14, 2017, 07:30:06 PM »
Hello,
Just like the title says...
I see a lot of people use 2 packs for 5 gallons so I assume 4 is is good for 12 gallons?

I dont mind over pitching a lager but I dont want to be throwing an extra \$6 at the problem for no reason.

thanks haeffnkr

A little math and you have the manufacturer's answer to your question.

3 might be alright, 4 would be better, 5 or 6 would be overkill.  Rehydration is optional but not a bad idea.

thanks for responding and I have found this on their site,  but I dont know what this means -

PITCHING: 80 to 120 g/hl for fermentation at 12°C – 15°C (53.6-59°F).
increase pitching for fermentation lower than 12°C (53°F), up to 200 to 300 g/hl at 9°C (48°F)

thus my questions -
How do I get from gallons and gravity to metric something or another?

thanks haeffnkr

I have had great luck with 4 and re-hydrated thus far.

thanks

I just did the math and confirmed 4 packs.

100 g/hl = 1 g/l

There are 3.79 l/gallon and you have 12 gallons, so you need 45.4 g.

There are 11.5 g/packet of dry yeast.  So, you need

45.4/11.5 = 3.95 packets of yeast.

I used 2 packs unrehydrated for 5 gal. of 1.050 pils.  Beer turned out great.
