+1.  I add my samples to a small jar with a lid. Two or three minutes in the freezer and it’s cooled to ~ that temp. ---

I take a small spoon and scoop a spoonful into an old White labs vial then drop it in a cup of cold water for a few minutes. ---

By the time I fill it with 3 spoonfuls of hot wort, its right about at 65 degrees. I don’t have a freezer nearby, so I use the same method I use for gravity readings.  Put a small sample in  a metal cocktail shaker and swirl it around in a bowl of ice water.  In 30-60 seconds it’s down to room temp. ---

I use a small syringe and pull ~0.2 mL. By the time I walk across the room it’s cooled, and there’s no concern over evaporation. ---

All solid ideas, looking forward to trying it. Hopefully I didn’t screw up the probe too much with all my high temp readings. ---

> [@a10t2](#): > > I use a small syringe and pull ~0.2 mL. By the time I walk across the room it’s cooled, and there’s no concern over evaporation. is this for mash pH or refractometer readings? I thought for a mash pH you would need to pull out an actual “mash sample” including grains, not just liquid… at least that is what I do… or is the pH of just liquid pulled from the tun good enough? ---

Pretty sure unless it is dissolved, it doesn’t affect pH. ---

> [@garc\_mall](#): > > Pretty sure unless it is dissolved, it doesn’t affect pH. That’s my guess. Even if the sample includes grain particles, you’re still only measuring the liquid that contacts the probe. ---

Pull grain for decoction,  liquid for pH. ---

Just started messing around with Brun Water - haven’t brewed a batch from it yet but I’m loving it so far. Appreciate the recommendations for it. ---
