Tripel II
I brewed a Tripel again on August 3rd. Why am I just posting about it now, you say? I'm lazy.
This time around I planned to use table sugar instead of corn sugar for 20% of the fermentables. Shortly before brew day I decided I wanted to try to make my own invert sugar instead of using straight table sugar. I searched the web and some books and couldn't find a definitive method for converting table sugar to invert sugar. I did find instructions for making candi sugar, but I wanted to make a sugar syrup instead of a hard sugar product. I decided on a combo/hybrid of various instructions I found online and from advice I got through the AHA TechTalk email forum. Here's what I did: I combined 2 parts table sugar and 1 part water (by weight) with about 1 gram of citric acid powder and heated the mixture slowly on the stove until the sugar was dissolved and the mixture was simmering. I simmered for about 15 minutes, until it was a very pale straw color. Then I cooled it to add to the fermenter. You may ask yourself, "Did he really make invert sugar?" That's a very good question, and I have no way of knowing the answer. At the very least I made a sucrose syrup which was easy to add to the fermenter. At best, I fully inverted the sucrose into fructose and glucose. I suspect the truth is somewhere in between, but I don't have any way of knowing to what extent the sugar was inverted.
The other difference between this batch and the last was that I split it between Wyeast 1214 and 3787. 1214 is an idiot-proof yeast that has attenuated very well without any extra fuss in every beer I've used it in. 3787 (supposedly Trappist High Grav) is a riddle wrapped in an enigma wrapped in a mystery. I love the flavors it imparts in a beer, but other than a small Belgian Pale I haven't been able to coax reasonable attenuation out of it. I used it in the quad-style beer that went into the club's bourbon barrel project, and it petered out at about 1.030 (from around 1.100). I learned later that it prefers incremental feeding of sugars (hence my desire to make a sugar syrup that was easy to add to the fermenter). This time around I held back all the sugar on brew day and added it later. I added all the sugar to the 1214 half of the beer a couple days after fermentation started. I added half of the required sugar to the 3787 portion after a few days, then the other half a couple days later. It still petered out at 1.030. Frustrated, I gave it a couple more weeks (and roused the yeast and bumped the temp up a tad), and it only dropped 2 more points. At this point I gave up on old 3787 and when I transferred both halves to secondary I poured the slurry from the 1214 carboy into the 3787 secondary. Active fermentation started up again within a day or two, and after a few weeks good old reliable chewed it down to 1.010. The straight-1214 half of the batch finished at 1.009 before I transferred to secondary.
After transferring to secondary I had about 1/2 gallon of the 1214 beer left over, which I put into a 2L PET bottle, chilled, and carbonated with my carbonator cap. I had about 1 gallon extra of the 3787 half, which I split between two growlers. I gave one of the growlers to Matt and kept the other for myself. I drank the leftover 1214 beer a few days ago, and I gotta say it was pretty tasty. I moved the 3787 leftovers into the 2L bottle yesterday, carbonated it, and had a glass last night. Again, pretty tasty. I can't wait to get these beers into bottles and compare them side-by-side. Bottling should happen within the next couple of weeks for the 1214 half, and a few weeks later for the 3787.
My recipe and procedures were essentially the same as my last tripel, so I won't go into the nitty gritty details. The only changes were I formulated for 1.080, used self-inverted table sugar instead of corn sugar, added it to the fermenters rather than the kettle, and split the batch between the two different yeasts.
