Brewfather and Starter question

[farmskis]

When Brewfather calculates the starter required size and it gives me a dme amount and a volume. Is this the volume after boiling? Meaning I should add a little more volume of water to account for the loss during a little boil to end up at the volume specified? I know it is probably not much as I’m sure the boil time required is quite small.

You only need to boil a starter for like 1 minute so there should be no loss.

If you're aiming for a 1.5-1.8 liter starter with a gravity of 1.037, you may end up evaporating 1-3 oz, depending how long it takes to reach boiling point, how hard or long you boil, or how long it takes to chill down.

By the time the wort has cooled you may end up with a gravity of 1.038-1.041. Those wort gravities are still fine for starters, although 1.037 is preferred for most regular starters.

If you always follow the same process you can preemptively add that extra amount of water to allow for evap/boil off.

BTW, you're not boiling directly in a (glass) flask, are you?
Instead, use a nice clean kitchen pot, onto which you can put a well fitting lid after the boil.

Issues from boiling directly in a glass flask or are you only suggesting your method is more convenient? I do worry that my glass flask could crack but figured it's being used for it's intended purpose?

Two things to keep in mind... the shape of the Erlenmeyer flask promotes boil overs and they can break while on the heat.
