I actually have to store all of my beer in the basement and the temperature is maintained at around 64 degrees. My beer has to bottle condition down there as well as stored. You say 70 or above is best (as I know it is), but I was wondering if you know the effects or disadvantages of letting it bottle condition at cooler temperatures; do you happen to know? I'm sure it's a debated issue, but maybe there is some information out there..
It just takes longer, that's all. At least 50% of all the "my beer's not carbed" are do to being too cool, obviously the other 50% is simply not waiting at least three weeks, when it is at 70, and it's a normal grav beer. Basically the closer you get to your yeast's dormancy temp, the more sluggish the yeasts are going to be.
I live in a loft, with hight ceilings, big old windows, etc. And it is way too costly to heat this place above 70. I keep the thermostat in the low 60's and use a ceramic heater in the area I spend the most time in, which is the bedroom/computer area.
So this time of year I don't even assume I'm going to have carbonation in a month after bottling. I keep the milkcrates where my bottles are stored in insulated sleeping bags which helps.
But basically the cooler it is the longer it will take.
I think a lot of new brewers stress this out too much. WHen you brew a lot, and start to build a pipeline, you are used to waiting, because you have batches at different stage, fermenting, secondarying, lagering, bottle conditioning and drinking.
For example right now I have a red and an ipa that I am drinking currently. I have a chocolate mole porter that is sort of coming into it's own, that I am entering in a contest the first week of Feb.
I have a few bottles of my year old Belgian Strong Dark, that is still aging, and I pull one out every now and then.
I Have a vienna lager in a secondary lagering for at least another two weeks, if not more.
I am going to probably bottle my Belgian wit this weekend, or I may give it another week to clear, but more than likely I will bottle sooner rather than later since it's coming up on a month in Primary, and I'm on a wit kick right now (in fact I've been buying wits lately rather than drink my red and ipa.)
I also have a 2.5 gallon barelywine that I partigyle brewed on New Years eve which more than likely will get racked to a secondary for a few months, and then bottle conditioned for a few more.
The second runnings, which is sort of a dark amber ale, I will more than likely bottle soon, I'm not sure. I really haven't looked at it and the barelywine since I brewed it.
And I am thinking about brewing something this weekend, maybe another lager.....
As you can I have beers at all stages or fermentation, so if something needs a few extra weeks to carb, or condition, I'm not going to sweat it. I'm about quality beer anyway. If nothings not to my liking/readiness, then I go buy some.
