After reading Zwickel's excellent post about renewing his yeast cultures I bit the bullet and made some slants.
I boiled 1 litre of wort and got it to hit 1040 and added 5 grams of agar agar to it. The test tubes I have were a good price but a bit narrow to work in, sorry Bud. I put them in the steamer for 30 minutes and also gave them a bit of starsan before I handled them.
My trouble seemed to be the agar started to go solid before I got to the last one. I did 25. I used the eye dropper thing that came with my refractometer to fill them. There was some burping and farting when I emptied it into the tubes. Is oxidisation a worry when doing this?
My only other question is not they have gone solid in the tubes when I rotate them in my hand the wort bed is obviously loose and rolls around with the heaviest point staying on the bottom. Is this bad as well?
