Thanks Richard!
I have an important business meeting today, I will get back to you email later and ask more questions. One thing which I wonder already is, what type of yeast did you used during your experiments?

Sincerely from Jeju,

Hi Frantisek,
   I have done quite a lot of alcoholic ferments using ginger, and started out much the same as the way you did. I have since moved on to making my ginger beer with malt extract/all grain, and hopping it just like any other beer.

Also using honey rather than refined sugar is another trick that I really like, I use it for honey ginger wines where I want to have a higher alcohol strength beverage (~8-10% ABV). Ginger + Honey + Red soft fruits & berries (especially plums) = AWESOME.

Standard advice with alcoholic ferments is to ferment until complete and resweeten/prime when the yeast is done. The higher the strength, the longer you will need to leave it age and develop flavour, but they also preserve longer. You will need a hydrometer/refractometer. If you bottle too early you can get some interesting bottle bombs.

Many of the components of ginger, including its fieryness are in my experience very volatile, and blow out your airlock when you do alcoholic ferments.

I am thinking of trying to introduce more of it at batch priming time instead (but I dont do batch priming currently). The theory is that you add your priming sugar into a solution, and siphon your ferment onto it. Leave until it fully mixes and then bottle with that. Your priming solution can contain more than just water, and you can use it to introduce flavour kicks or volatile aromas lost during fermentation. Haven't tested this yet.

I have haphazardly taken down odd notes and photos here: https://www.facebook.com/The.Sum.of.all.Beers

Been meaning to store this in somewhere more ordered, but life is a bit too busy at the moment.

Hi Michael,

Personally, I stopped brewing beer a few years ago when the price of ingredients doubled and it became cost prohibitive for me.

One of these qualities is the alcohol concentration at which the yeast attenuates ie. stops functioning. Another quality  is how well the dead yeast flocculate and settle out of the liquid.

>The quantity of yeast you use is not particularly relevant since the yeasties multiply and theoretically one yeast cell could (eventually) ferment any amount of beverage. Asking at brew shop is a good idea. 
>Also keep in mind that yeast are reusable, so you can save some of the used yeast in a suitable, airlocked bottle. A really fun thing to do is to have a fresh batch ready for ferment when you siphon off the finished brew off the old yeast. Dump the fresh batch on top of the old yeast and it will take off full bore in an couple of hours.

>As for adjusting the sweetness, I suggest using a non-fermenting sweetener, like stevia or lactose. I remember having a problem with a cider I made that would not stop fermenting. I had let it ferment until the yeast stopped, but it ended up tasting incredibly dry. When I added more sugar to get the right  sweetness, the yeast would re-activate and within a week or two the sugar would be gone and the cider would be too dry again.

>Speaking of flavorings, it is often best to add them after the fermentation. When I tried making a cherry cider, all of my great cherry flavor I'd added before fermenting went up in the bubbles my yeast gave off while it was working on the sugar during fermentation.

>As for water, remember that Anchor brewery and I think speakeasy too, use straight SF tap water. Fine product from Hetch Hetchy. Great taste and fine to brew with. Chlorine & flouride and inconsequential no need to filter, sanitize or mess with the water from the tap; "they" already do that.

>As for fermentation vessels, most people I know use either 5 gallon food grade plastic buckets with lids or glass carboys.  Fermentation locks are necessary to keep out bacteria and  errant yeast, especially during the later stages of the fermentation when the yeast is not throwing off so much CO2. Many of us rig up a blow off tube for the first part of the fermentation because ordinary locks can get clogged with vigorously bubbling yeast and blow out..

>I have no idea what temperature 25C is, but the nice thing about living where we do is that yeast like it too. 60-70F. I would be leery of using a submersible pump, since the brew is not circulating  and you're likely to get part of the batch too hot. Traditionally we keep blankets around the  brewing vessel and they make electrically heated wraps for fermentation containers.

>Hi to all and to alcoholic brewers especially,
>I just started a new experiment aiming to brew nice alcoholic ginger beer and I have some questions below. My first batch will be most likely too sweet,  but it is the max end of the screening which I want to do (on the sweet side), the details for the first experiment are below. I would like to ask for recommendations for the next experiments, I put some ideas below at the end. It is possible that I may be able to sell the final product, of course I plan to share the technology, recopies etc.

>It started to go on within few hours and it is fermenting really strongly, anaerobic fermentation as mentioned. I tasted it yesterday (two days after starting) and it is quite sweet still and bit alcoholic. I am thinking about starting another brews under same conditions changing just the sugar concentration to 15% and 10%(w/v). What do you think about that? Below are more ideas, please do remember that I do not have too much experience with alcoholic fermentations. Also I ferment in the same environment all my probiotics but I am using the clean newly bought plastic vessels for the alcoholic ginger beer.

>I should mention that I do not have access to any specific yeast now, I'm bit low on cash, otherwise what strains would you recommend? I heard nice thinks about California Ale yeast but I'm not sure if it would be suitable. Maybe some more "cider" style yeast would be better?
