[foodhacking] Fw: Brewbot - beer making

Just forwarding very handy info from Richard, thanks! I will come back to it and answer some of the things and ask more questions in day or two.

If you are making a 20L batch, you wont be able to cool effectively without using an active cooling mechanisms, or doing a sterile passive cooling (aka No Chill).

I use No Chill myself, active cooling is very wasteful of water, unless you can either recover the water, or you have very expensive chillers that are more efficient.

I will find you a link on no-chill brewing, but what you want is a 25L HDPE plastic water carrier. You transfer your beer from the kettle when it is still hot (at 0 mins if you can), into the plastic container. When it is done, you squeeze out as much headspace (air) as you can - which may be difficult. Cap it tightly, and then tip it on its side, so that the hot wort makes contact with *every* side of the container. In essence you pasteurise the wort in a sealed vessel. Your beer will keep for long periods in these cubes. As it cools, it will contract, and you know it is safe to brew with. If you do it wrong, and dont kill everything in there, it will ferment when it cools. If you see gas expansion after a few days, dump the beer (its a primary breeding environment for botulism if you do it wrong).

Your recipe looks good. Its looking a lot like a dark german or belgian style beer. For hops I would then use something european, like perle or saaz. You want those hops to stay out of the way. If you like the spicyness, I would favour Saaz. I will send you a recipe of mine for a belgian blonde and you can get the proportions out of it.

You can make the beer a bit sweeter by mashing at a higher temperature (~68C) but I would avoid doing that for now, as it is quite an advanced skill, and a bit much for your first brew day.

Skip the gypsum for now - you dont know what your water pH is, so messing with water alkalinity is not something you want to worry about., again this is an advanced skill.

You are using pilsener malt, so I would recommend a longer/90 minute boil, to remove volatile undesirable chemicals like DMS and its precursors. Dont cover the kettle while this is happening.

Are you sure you have the right yeast? S-04 is the english style yeast, US-05 is american ale yeast.

Fermentis T-58 might be what you want aswell - it will introduce some clove like spicyness, and is happy with high fermentation temperatures.

Why are you only doing a seperate steep for Carafa2? This is your first brew, so mash everything together. The beer will turn out grand - your recipe is fine, and the munich will put a bit of sweetness into it. The dark grains will put complexity and body and colour, and their proportions are good.

Thanks Richard!
>By the way I'm now planning to start experiment with dark beer, I have been recommended the recipe below for a simple start, just ingredient not really the procedure, that is something what I have to study. I have been warned that I should be very carefully about the cooling down face which is suppose to be as quick as possible (I did not make beer (malt based beer) before. I would like to know your suggestions and recommendations. I like sweeter caramel like taste of beer, I do not like bitter. Any recommendations about procedure on brewing is welcome! I have standard kitchen equipment plus large kitchen equipment, straining bags, cheesecloths etc. Please consider that all ingredients which I need will have to be imported to Jeju, Kore where I'm now living.

First versions would be more about experimenting building up the base for more robust and simple device which would be dedicated to household "production" use rather than an experimental adventures. However the both lines - production and experimentation, in the future should be developed.
