With the Erlenmeyer flask sitting on its stir plate and the starter well and truly underway I’m re-reading my notes from the last Yeti’s starter, which was coincidentally the first one I ever made. Since then I’ve done maybe half a dozen of these and am a lot more comfortable with the procedure, so much so that this time around I didn’t take any pictures or gravity readings, planning simply to rely on visual cues to confirm it’s ready to go in 2 days’ time. The only thing different this time around is the addition of Lipohop, an anti-foaming agent made using natural ingredients, and given that I didn’t have to clean the stovetop or nanny over the flask I think it’s safe to say I’ll be using it again.
- 123g DME
- 1 litre water
- 1/6 TSP (approx) Lipohop
Lipohop is an anti-foaming agent, approximate dose should be between 0.02 and 0.05 grams per litre. I think 1 TSP is normally around 2 grams, so complete guess is to aim for about a sixth of one small TSP. The small tar-like blob easily slid off the teaspoon, which had been sitting in boiling water for a few minutes to sterilise.
The Erlenmeyer flask was prepared by boiling some water in it to sterilise, then dumping that out in order to rapidly dry the interior, before being placed on scales for addition of DME using PET bottle-derived funnel. Water added to just above the 1 litre mark (guess anyway since there are only 800 and 1200 ml marks) then placed on boil and Lipohop added as well as the stirrer magnet, which I’d also sterilised with hot water along with the spoon.
Lipohop appears to be very effective indeed at suppressing foam during boil, and any bubbles which are produced (mainly from the stirrer magnet) immediately disappear on the surface. There are some small black particles visible in the boiling wort, presumably solid hop matter which won’t dissolve. Boiling the whole lot for 20 minutes should at least guarantee it’s sterile. Colour also seems a little darker than my usual starter, at least while it’s still boiling. Maybe I could get away with a smaller dose of Lipohop next time?
