You caramelized a lot more than I did. My recipe called for 24 oz., which I caramelized down to raw syrup, reconstituted with hot water back up to the original quantity, then tossed it back into the main wort.
When you caramelized, how do you treat the reduction? I tried to use a thermometer to see what the hottest temp I was able to hit was. I wanted to get upwards of 350f, having read that conversion occurs in caramelization at around 350f. I think I need a candy thermometer... mine weren't able to report that high. So I brought it to a good boil. The rich syrup developed very fine bubbles, then I took it off, fearing I'd burn it. It didn't appear or smell burned.
Just curious how you approach caramelizing and how you know when you've hit your target in terms of knowing when to pull it off the heat.
There wasn't a target temperature, the recipe I used (Boundary Bay Scotch clone) only called for boiling down at least a gallon of the first runnings then adding them back 10 minutes before end of boil. Just need to make sure it doesn't scorch. I used a relatively shallow pan so it would cook down faster. Getting it to come up at least to 1.2 seems to be about right.
If you don't have a refractometer, use your taste buds before and after; it doesn't need to be a syrup.
