Cider Update

christopher.falk — Tue, 22 Sep 2009 11:01:25 +0000

I went ahead with the cider recipe and it’s fermenting in my 7.5 gallon bucket right now. Mistakes were made, but I’m thinking they won’t be a big deal.

I bought 7 gallons of local cider from the grocery store – it was pasteurized – and decided upon some research to skip the Camden tablets entirely. I sanitized the bucket, lock and cover and dumped it all in. OG on the cider was around 1.042.

Into the cider went both vials of yeast, a White Labs English Cider WLP775 and a White Labs WLP530 Abbey Ale (Westmalle yeast). Then I realized that the cider temp had to be somewhere in the low fifties. Not good.

No action for 24 hours, but then a little bit of bubbling, and by this morning it’s cranking. The top of the bucket is bulged up and the lock is burping away. Without Campden tablets I do have to be very careful about the timing of my next sugar addition (the honey, molasses and cane sugar) because once the yeast are done something else might move in. I intend to check the gravity in another 24 hours to see where we’ve gotten to.

The cider yeast attenuation is over 80% and the Westmalle is around 80% tops so this should be nice, dry, strong cider when all is said and done.

Tripel Racked to Secondary

The Tripel has been racked to its secondary where it will live for a week and then head into the fridge for a week of cold conditioning. I was shocked to find it had fermented all the way down to 1.008! That’s the best attenuation I’ve had yet, assuming I hit my OG which I’m not sure about, practically 90%.

It smells great and tastes good too, all kinds of clove, fruit and not much of an alcohol-heavy flavor at all. Looks like I survived my fermentation temp rise so far.

This one should come in around 9.5% ABV once all is said and done.

Banana Overload

The smells coming from the Tripel as it ferments have been pleasantly fruit-like but subtle. Once the cane sugar went in, however, the room nearly filled with a banana ester flavor. It must be something to do with the way the yeast process the cane sugar. Since we’re doing a renovation on the house my brewing books are boxed away in storage so I can’t do much for research.

I’m concerned that the esters will be too powerful, or linger too much, but maybe a lot of it will be reabsorbed as the yeast go dormant. Either way it’s to style from what I’ve read.

Some Sugar Added

So I took a reading on the Tripel tonight, three days into fermentation, just as the yeast was slowing down (a bubble every 10 secs or so). The beer was starting to clear up a bit on the top couple of inches, with a settling yeast cloud below.

I roused the yeast first, then added the cooled syrup I made with 2.5 lbs of boiled table sugar.

Before the sugar was added, the gravity read 1012. That’s incredible for three days even with the large starter, and I think tells me my mash went as poorly as I thought. Although it’s consistent with the lower mash temps yielding a more fermentable wort. Since I forgot to take my original gravity measurement, I can only guess based on the recipe what my starting point was, but according to ProMash it’s 1061. That’s 80% attenuation – more than Wyeast even specifies for the strain. So I’m naturally suspicious my OG was really in the 1052-1055 range.

Either way this beer seems to be very busy even a scant 15 minutes after the sugar addition – should be cranking tonight.

Fermentation Temperature

The Tripel is down from a high of 78 deg last to about 72 thanks to the window left open and a box fan blowing air across the carboy all night. Not sure I can cool it much further – it’s still very active.

Tripel Fermentation Video

Here’s a video of the Tripel fermentation, 24 hours in. We’re up to 76 degrees on the carboy thermometer-strip. Yikes – no good!

Tripel Fermentation Underway

christopher.falk — Tue, 08 Sep 2009 11:37:31 +0000

I woke up this morning to the Tripel fermentation lock bubbling every second – no churning yet but things are definitely getting started. My starter seemed a little slow but this guy’s getting going. My only worry is temperature…I had it cooled to 64 degrees in the kettle according to the thermometer I trust, but the carboy temp strips said more like 67-68. They are reading 70 now so hopefully this means the fermentation is really in the 66-67 range and we’re on track. It’s going to heat up fast.

The gamble is whether I can find my blowoff hose before things really get roaring.

Helles Goes to Secondary

christopher.falk — Sun, 12 Apr 2009 23:33:12 +0000

The Helles has joined its darker cousin in the lager fridge. After 2 weeks in primary at 54 degrees (warmer than I wanted but that’s the basement for you) I’ve racked it off to secondary. We’re at 70% attenuation so far – 1.050 to 1.015 – and hopefully it will reach 1.012 by the time all is said and done for final attenuation of 76%.

I tasted the sample and it’s full of maltiness – very much the grain taste on the back of the tongue which probably won’t be as present at proper lager serving temps. An earlier sample from a few days back still had lingering Hallertauer flavor but that has faded somewhat even in that short time.

I’ll probably keg it in 2-3 weeks, a month at the most.
