Notes

BREW 1
=======
Ferment: 2017-05-25
secondary: 2017-05-31
Yeast: Safale S04

Meshing went bad somehow, the OG became way too low, about 20 points. Could be the reason of new sparging where we pumped water (74 degrees into the wort and continuously tapped the wort out to the boil kettle.
Next time, do it different! That is let sparge water stay for a while and tap out to kettle like we have done before.

2017-05-31: Dryhopping in cornelistap under 1.0 bar pressure.

OG: 1.041
SG: 1.016 (dry hop, under pressure ~19 degrees)
FG: 1.016

BREW 2
=======
primär jäsning: 2017-08-01 (OG 1.050)
Sekundär: 2017-08-05 (SG 1.016)
Yeast: safale us-05

OG: 1.050

Flödeslakning under dryga timmen, cirka 1 liter på 2 minuter. 30 liter totalt efter lakning,
Lactal, användes vid mäskning, drygt en kork för att få ner PH från 5.8 till ca: 5.3

Kokade ner ca 6 liter (från 30 till 24), något för lite för vårat recept vilket resulterade i ett lägre OG (skulle ha landat på 1.068). Kunde ha kokat ner mer men svårt att läsa av våran kittel hur många liter som finns i den..

Hopstand efter kok till mindre kittel och lät ligga i 30 minuter och efter det pump till kylning.
Landade på 24 liter i den nya koniska jäskärlet av plast. Tryckte in den i kylen med 17 grader som börvärde. Använde Safale S-05, Amerikansk ale istället för English.

2017-08-05: tappade om till betterbottle. Koniskt jäskärl ganska onödig att ha i kylen då den behöver vara monterad. SG på 1.016 redan efter 4 dagar. Fortsatt jäsning i 17 grader.
