We were thinking about upgrading to a glass carboy for our next batch. I am guessing this is soemthing we could pick up on the cheap. Any idieas?
Also, our hudrometer reading came out at 1.036 when our starting range was supposed to be 1.052-1.055.
What could have caused this variable and what does it mean in the long-run? Just a lower alcohol content?
Thanks for your help all!
Extract will darken during the boil - it's tough to get a light golden color with any extract brew. Longer the boil, the more the sugars will caramelize (but the better the hop utilization will be).
I vaguely remember reading somewhere that the beer may lighten slightly during fermentation - but only slightly. I could be mistaken. Also, unless you're taking specific color readings, it can be tough to judge the color during the process. You're likely to be looking through a much greater quantity of beer, filled with little yeasties and trub for light to light to have to fight its way through - it may end up looking lighter in a typical beer glass when finished. But don't expect Miller Lite in color - think more like Bass Ale.
As far as the hydrometer reading, it can be influenced by the wort temperature you took the reading at (they're usually calibrated for 60°), but that won't make the difference between 1.036 and 1.052+
A few possibilities: were there any little air bubbles sticking to the hydrometer when you took the reading? That could make a difference like you describe. Was it a somewhat short boil, or did you add extra water (assuming you did a partial boil) to get the temp into fermenting range? If that's the case, yes, you'll have a lower-alcohol brew (but maybe more brew).
As far as a glass carboy, that's highly recommended - but don't wait for your next batch - use it for the secondary fermentation (i.e. siphon the beer off the dead yeast and other gunk after the airlock bubbles - at most, say, only once every two or three minutes - usually takes 4 - 7 days for me. Too long on the gunk can yield off flavors, and the beer with benefit greatly from being siphoned into the carboy.) With a glass carboy, you can keep an eye on it, and see when the remaining yeast has dropped to the bottom, so the beer looks relatively clear. That's when you can fine it (if you like), prime and bottle.
I've gotten leftover glass carboys for free from people with in-home water coolers - I imagine the plastic ones would be okay, too. One trick I use in the secondary - I take an old sweatshirt, soak it in water and drape it over the carboy (and the carboy is in the basement over a drain). It further protects the hops from light, and the evaporation keeps the secondary fermentation a little cooler. Maybe I'm just imagining that it makes a difference - I haven't done scientific comparisons.
Just my 2¢ - others are free to disagree.
