to rule-out/in asphalt, what happens if you spill a small amount of gasoline or mineral spirits on it?
Does the puddle take on a brown color? (I'm talking about a tablespoon, not a quart.)
I don't have much trouble getting mine running without throwing the bar.
Getting things centered seems to be the primary task.
Could it be an unbalanced bar or uneven flask bottom?
Another stir bar is a pretty cheap and useful item to have on hand anyhow.
I use a igloo cooler but even so I preheat to ~68 degrees. I mostly brew in the winter months so I'm mashing in the garage. Preheating in winter brings the vessel up to basement ambient and allows me to dial-in Beersmith as though I only brew in the basement which is much more temperature stable.
I just put three plants in this morning. Still looking for some Pink Brandywine but in case I don't find them I put in a German Queen plant. Haven't tried them before but I wanted to have another heirloom in case I can't find the pink Brandywine. Had great luck with them last season.
I have had this happen a couple times with NO ill-effect.
Why can't you sample before bottling????
You can't undo it so sampling before bottling might save you some work if it isn't worth bottling.
The pay-once model does not exclude updates necessarily. That may just be the implementation that the vendor chose. Make no mistake, subscription model is profit driven.
