Re-streaking plates

Some of the first plates developed a mould, so replated. This time using a shoe box as a make do shield.

Much happier with the streaking, although it looks like I might be taking too much on the loop. I re-shaped the loop to be a smaller oval. Plates should be stored with the agar facing downward, and I have sealed with black insulating tape and stored in the fridge at 5c.

I managed to get a good looking round colony from the la Trappe adhoc playing, and have streaked that, as well as mangrove jacks b07 British ale
and m27 Belgian yeast from slurry.

Saving yeast onto plates

Damian come over and gave me hand. I saved my yeast from the restarted bottles that where stored in sterile water to plates from delta education is Carr rd. I also took samples from Daimen’s library and they are culturing up now.

20140708-183941.jpg

On the British ale plate (not expected to grow as there was very little on the slant, I made an adhoc inoculation loop using the wire tie from the la Trappe bottle, swilled the last if the bottle to stir the sediment, and put into marked areas on the plate.

Reviving 15 year old yeast

We were fortunate John shared with us a 1999 Thomas hardy ale for our judging course.
I added stored wort and oxygen, and revived the yeast.

Next step is to make a 1l beer…. And harvest the yeast.

Wheat beer starters

At the beer judging course tonight, we tasted wheat Beers – the bottles throw quite a bit of yeast so it would be rude not to do a yeast starter. I used my newly set up oxygen set up to add o2 to the beer yeast and 1/2 of a 500ml wort starter from the fridge at 12c, left at room temperature ~ 20c

Wort aeration and diffusion stone

In preparation for a disposable O2 setup with regular, I have set up diffusion stone on a wand using john guest fittings. I’ve splice the co2 line, so now I can carbonate thought the .2 micro stone for carbonation, and also use the same gas in post with a stand alone gauge for monitoring those suspect leaky kegs!
The wand is a recycled dip tube from a co2 fire extinguisher

Castle pub tap

Finally upgrade from the picnic tap!
My Dad got this tap from my grandmother Ruth from the castle pub in Wales in the 70’s. It’s finally operational, pouring a green hop pale ale with the hops grown 10m away by
my neighbour Ellen.
