Did a wee heavy 80- a while ago, before I switched to AG. Did the recipie as published. Did not use smoked malt, and did not do kettle caramalization. What I ended up with was a high alcohol brew with little flavor. Looking to up the flavor and am debating on whether to use kettle caramalization or bite the bullet and toss in a half pound of smoked malt. Any thoughts? Before the flame wars erupt, I am not entering competitions, and while I like to keep within the style guidelines as to IBU and SG, I am not a purist. I understand that the style does not recommend smoked malt.
There's a couple methods that give kettle caramelization, from what I've read: heating while draining the mash tun, and longer than 60 minute boils.
All but a few of my brews over the last 9 months, or so, employ both. I do 90 minute boils no matter what. I try with all of them to, at the very least, keep some heat on them to shorten my brew day by shortening the time to boil.
Since I started this, my brews have been much better, and darker than what BeerSmith tells me they'll be. Yay, caramelization!
Also, everything I've read on Scottish Ales, and especially Wee Heavies, you gotta employ one of these methods. Kettle caramelization, whether by keeping the mash runoff hot to near boil, or boiling 90+ minutes is key.
So, also being a scientist and engineer, do everything the same on the next batch but change the variable for heating. Employ one or both techniques as I mentioned and compare your results.
