A few days ago I saw a post by someone asking about Erlenmeyer flasks and he was told by several people to avoid the narrow mouth flasks because they were too difficult to work with. This got me to thinking that perhaps my way of making a yeast starter isn't so common after all and that it might be useful to some if I posted a few pics of how I go about it. So here goes.
First, I start with a plain piece of paper and a ruler.
Then I use the ruler to make some folds, kind of like making a paper airplane.
Once the creases are in place, then you can wrap the paper around and form a cone, albeit with a very small point. So I cut that off.
Then, with the flask and the paper funnel in place, I zero my scale
add however much malt extract I need to add (in this case, 150 grams)
With this funnel, the extract goes in as fast as I can pour it.
I then use the scale (since it's right there anyway) to tell me when to stop adding water. In this case I wanted 1.5 litres, so 1500 grams plus the 150 grams already in there. I overshot by a gram it appears.
Then I put some foil on and boil it for 15 minutes. The foil is sterilized this way and I keep it on the whole time it is on my stir plate.
I realize this is all very basic stuff for most of you, but perhaps it is helpful to a few of you.
All the best,
Matto
