How to make an optimal fermentation for ginger beer with ginger bug

Right so there's no "optimal" method for this, brewing is a balancing act between sweetness, alcohol, carbonation-pressure and yeast. Even things like the shape of the fermentation vessel effect the ...

How can I raise alcohol content in my rum?

You will not achieve 40% using fermentation as the only technique. Yeast have a certain alcohol tolerance that is usually between 14% and 18% (wine yeast), above that percentage, yeast will stop ...

Guess Alcohol By Weight With ACTUAL Weight

You cannot do that based upon the weight of a sample of your final beer, because then you have a mix of water, alcohol and final sugars: Final weight = Weight of water + weight of alcohol + weight of ...

Gently stir fermenter before bottling?

No, the alcohol is dispersed throughout the beer. Indeed, the entire thing is homogenous.

Measuring alcohol content

If you don't want to do refractometry or hydrometry, your next best generic option would be ebulliometry, which is basically measuring the bubble point of the liquid, where the bubble point depends ...

Why do we use 95% alcohol in Liqueurs?

The alcohol in limoncello or other liqueurs is almost always industrially produced, and thus fit for consumption. It does not contain methanol or fusel alcohols. So, made this way, liqueurs are not ...

Sensor for measuring alcohol content of wine

There are relatively affordable devices (iSpindel and TILT) that continuously report specific gravity wirelessly. You can use the data to derive the alcohol content with a pretty good degree of ...

Measuring alcohol content

A vinometer can mesure alcohol of a dry wine (all sugar needs to be fermented). You would need to add some dye to see the results if you have a transparent liquid. It can usually measure between 0 ...

What is the best plastic to use to store alcohol?

There is nothing better than glass from a standpoint of oxygen ingress. The next best choice would be PET, followed by polyethylene and polypropylene. With PE and PP the density of the material (which ...

Beer, alcohol - body ratio

Well you can quite simply calculate the amount of ethanol consumed easily: Stout 0.2L*13.49%=26.9mL Double IPA 0.33L*8.5%=28.05mL It would appear that the 0.33L DIPA delivered more ethanol.

Does distilled water and/or alcohol cause airlocks not to bubble?

To elaborate on my comment more. Some airlocks won't show tale tale signs of c02 that has already escaped if using a solution in them that won't form bubbles on their surface like pure water or ...

Do sugar alcohols count against yeast alcohol tolerance?

Short answers No and No. Although erythritol is an alcohol it does not count against the 'alcohol' tolerance of yeast. When we speak of the alcohol tolerance we are not strictly speaking about all ...

Measuring alcohol content

IMHO HPLC is the best method probably followed by spectroscopy. measuring ABV by distillation is "indirect" due to the formation of an azeotropic mixture between alcohol and water. They cannot be ...

How to calculate liqueur alcohol percentage and final volume

Let's see if we can reverse engineer this :) The density of 95% ABV spirit is ~ 0.8 Therefore: 500g/0.8 => ~625ml of 95% spirit. 500g water is 500ml. but your 500g of sugar as it disolves will ...

How to calculate liqueur alcohol percentage and final volume

Most alcohol is labeled with ABV (Alcohol by Volume). Therefore, if you have 1L of 96% alcohol mixed with 1L of water, you will have 2L of 48% ABV. Looking at density is something we do when ...

My mead has a lower ABV than I hoped

there could be a few things that caused this. One could be that the yeast wasn't firing at 100%. It could have lacked nutrients so it wasn't able to ferment fully. There could have also been a ...

Should I be worried

If you are using a simple pot still, you may not get high enough proof to burn on your first run. Without knowing actual volumes and ABVs here it is hard to say what is the case here. Normally when ...

Sensor for measuring alcohol content of wine

While I think the discussion so far has been good, I also have felt like alcohol contributes something akin to sweetness. While I appreciate the argument that high ABV beers tend to have high FGs ...
