Is the temperature range listed on the yeast manufacturers' websites ambient or fermenter?

They must be referring to the temperature of the yeasties themselves, which would be the fermenter temperature. Nothing else makes sense.

BrewJacket - How does this Work and How can I replicate it?

It uses peltier devices - a thermoelectric cooling/heating device - when a current is applied they chill on one side and warm the other. They're quite common but relatively inefficient in terms of ...

Bottle conditioning / carbonation temperature

Beer needs to be warmer when you bottle condition. This allows the yeast to work hard at getting the priming sugar into CO2. However, too warm and the beer will stale faster. I recommend moving the ...

What is the proper way to maintain temperature in a water cooler Mash tun by adding hot water?

Most of the heat is usually lost through the lid in coolers. Cooler lids are not well insulated. The bodies are. This is because they are meant to keep things cold not hot. Heat rises and a cooler ...

What is the ideal temperature during carbonation with priming for an ale?

Optimal about 18C-20C. But almost any temperature between 5 and 25 will work. If cooler then it takes longer. It is possible to go higher but there may be some more fruity esters produced although not ...

Is there a temperature my boil should not exceed?

First off, there's no need to worry about leaching tannins in the boil. Tannins are mostly found in the husk fraction of the malt. This means you have to be careful with the temperature only when the ...

Is the air glug in a conical not causing oxidation?

First of all, once you remove the trub bulb, there is no need to add another one. If you don't add another trub bulb and open the valve, how are you getting your "glub"? The idea is, attach the bulb ...

Considerations for temperature control of a freezer?

Yes, if you switch your freezer on and off in quick succession the compressor gives up the ghost and you have a box that can actually turn into a semi-oven. Good news! thermostats like the STC-1000 ...

What is the ideal temperature during carbonation with priming for an ale?

You are correct when you say the warmer the brews are stored the faster carbonation will complete. Carbonation is a mini fermentation, so ideally you would want it to complete around the same ...

Is the temperature range listed on the yeast manufacturers' websites ambient or fermenter?

It is definitely the temperature of the fermenting liquid. What you normally would do is fit a thermometer (like a crystal thermometer) against the side of the fermentor. Then you have a good view of ...

Safest way to heat an (enclosed) fermentation chamber

I use one of these seedling heat mats as my heat source inside a freezer. They're built to have stuff sitting on top of them, they're water resistant, and they heat gently. Seems pretty safe to me. ...

The main reason you need an external temperature controller is because the thermostat on a fridge or freezer isn't in the right temperature range. Also they are typically not calibrated and offer only ...

Is there any real need for a heating element on an STC 1000 fridge setup ( for most/many setups)?

I have 2x fermentation fridges, and both have heaters (heat-pads) connected to the STC-1000. My fridges live outside, so suffer winter lows (~ 0C/32F) and summer highs (~ 45C/113F). If you're ...
