Beer brewing foam blow out!

Sometime the yeast fermentation is TO active.

Resulting in a blowout. Blowing air into to brew is automated by my brew computer. So i didn’t check myself meanwhile .. Maybe somekind of overspilling sensor can be made??

My beer brew computer/environment ( computer controlled fridge )

Beer in this yeast container was a Rauchbeer / smoke beer

Beer glasses

I’ve collected some beer glasses in the past, but i didn’t have many.
I hated the fact that your are not using them OR (even worse).
Put a different brand of beer in the branded glass!

So i bought a set of these:

I like the no-brand no-logo … just-a-glass look.

So why different types of glasses. Some say “nonsence!”

Welllll .. maybe for a part.
Click on the images for more information about the glass.
Below i will use the names of the glasses, these are NOT generally accepted names.

  • Some types of glasses like the “Breughel” concentrate the aroma.
  • A heavy stout mostly has less volume, it looks weird in a pint glass.
  • Besides the volume, a lighter beer looks better in a “Prague” glass
  • Some glasses are better suited for keeping the beer cold, other you can warm a little in your hand.
    ( Beer is NOT always best cold! When you drink it too cold, you will numb your taste buds. Most beerbottles have a temperature suggestion)
  • Bulb glasses like “Grand Cru” will keep your foam longer.

There is no need for a foam head on your stout, so use a “Gusto” for example.

Temperatures (a little example) Do your research on the internet!

  • 4 degrees celsius : Light lagers, Pilsners
  • 7 degrees celsius : Blondes, Wheat and Hefeweizen
  • 10 degrees celsius : Red, Amber, IPA, Tripple
  • 12 degrees celsius : Bitters, Scotch Ale, Stouts and Porters
  • 14 degrees celsius :Imperial Stouts, Double bock, Barley Wines, Milk stouts

Schematic drawing beer brewing

Made a drawing about the steps involved brewing beer. Made this after following a workshop beer brewing at t’wort wat

Just to have a follow-along sheet .. so i dont forget a step.

UPDATE : Used this to teach others about brewing later on.
For friends, family or colleagues.
See post about NA Brew and BBQ day

Some lager tasting

I don’t drink lager that much any more, but still …

I was wondering which I liked the most of the Dutch Lagers.

Comming from the east of the Netherlands I drank a lot of Grolsch.
But lately I liked the taste of Hertog Jan more.

Welllll .. after tasting these .. still Hertog Jan number 1.

I liked comparing that much, that later we did:

  • Sherry
  • Brandy
  • Rum
  • Some foods

But the results came in:

Best

  • Hertog Jan
  • Palm
  • Heineken (unexpected)

Worst

  • Jupiler
  • Vedett
  • Schutters

First day beer brew course

Today i started my first day brew brewing course at t’wort wat

After making mediocre beers, by myself .. using beer kits and so on.
I really wanted to make propper beer.
Fresh base ingredients, from the base up.
I wanted to know what i was doing and why..

Update 2022: I’ve made many beers since, together with Monique and Coline.

Makgeolli

(I made makgeolli multiple times, pictures are of multiple dates.
I started with a workshop at a hackers event called OHM2013)

Much like sake, a fermented rice ‘wine’ .. see other post

Makgeolli is a traditional Korean alcoholic beverage made from rice and nuruk culture. In this workshop we will prepare the single fermented makgeolli called “Takjangdzu”. We will focus on a proper rice preparation which includes proper washing, drying and steaming (or boiling), cooling and subsequent inoculation of the rice by the active culture in this case nuruk. If everything goes well we will also harvest the takjangdzu which was already pre-prepared and taste it. The alternative options to using nuruk as a culture will be discussed, suggesting either kōji (Aspergillus oryzae) or yeast (Saccharomyces cerevisiae).

>Just quick one. I have checked the recipes which you shared with me quickly. The first recipe is close to the todays industrial style of production of Korean Makgeolli or the Japanese style of "rice wine making" because it uses koji                                                                                                                                                                                    
                                                                                                                                                                                 
>http://en.wikipedia.org/wiki/Aspergillus_oryzae                                                                                                                                                               

>The second recipe uses steamed rice (that is what we do at Susubori) and yeast. Using just yeast is not usual for Korea, we for example add yeast in addition to nuruk (for 1 kg of rice (chapsal - sticky ric
e recommended), we use 90 g of nuruk and 3 g of yeast (baker yeast I assume, no one knows which really annoys me). We wash 4-8 times the rice in cold water to get rid of the starch, let it steep for 2.5-3 hou
rs, dry it for 40 min and steam it for 20-25 min. Cool it down for 30-40 min to room temperature and transfer to the fermentation vessel (leave around 50-70% free place for air so 5 l wide mouth container suits well), add nuruk (90 g of wheat based nuruk, there are many different types) and yeast (3 g baker yeast should be fine) if you like and 1 l of water (rice ratio to water 1:1, that results in sweater type
 and more viscous beverage, if you go 1.2 (water):1 (rice) than you get dryer and more acidic beverage), mix well but gently not rupturing the rice grains, making sure that the nuruk falls apart             
                                                                                                                                                                                                              
>http://en.wikipedia.org/wiki/Tapai                                                                                                                                                                            
                                                                                                                                                                                                              
>Let to ferment with slightly "open" lid on the container for 3 days, mixing every day properly, after that let to ferment for another 3-4 days (max 5-7 days all together) and taste regularly and harvest when you feel it is right. The harvest is basically straining the mixture through the "fine straining bag" and bottling. Bottle the liquid leaving around 10-15% of the bottle to air (carbon generation can be quite vicious) and keep refrigerated.                                                                                                                                                                                
>Anyway I hope it helps, by the way the recipe above is for single fermented makgeolli which takes in total less than 7 days and is more prone to be sour than the double fermented one.     

To brew your own:

Ingredients:

Directions:

  1. Soak rice in tepid water for 1 hour
  2. Cook the rice until it is about 80% cooked.
  3. Allow the rice to cool
  4. While rice is cooling break nuruk cake until small pieces and mix into water until it turns a mud-like color.
  5. mix in rice
  6. transfer mixture to an earthen jar (if unavailable a plastic jar will do just as well)
  7. cover jar with a paper towel, or light cloth and allow it to ferment for two days
  8. cover jar with lid and allow to ferment another two days
  9. stir the makgeolli twice per day throughout the whole fermentation process.

Bottling:

  • Add one tablespoon of sugar per liter of makgeolli to each bottle
  • Filter makgeolli mixture through a cheesecloth and pour through a funnel into each bottle
  • seal bottles if possible, and refrigerate until ready to drink

Serving:

  • To be traditional, transfer your makgeolli into a kettle, and pour into a small, bronze bowl
  • Add water to taste

Skittles Vodka

Update (2022) Something i’ve been doing for years now.

Making skittle vodka.

If i remember it well, is was a students solution to get a cheap ‘fancy’ drink. Vodka is cheap, and skittles or other candy was easily obtainable.

Buy a bottle of vodka, not too cheap, but certainly not a pricy one.
Get some bag’s of kittles. (does are mixed so you have to sort them by color/taste)
Take some small bottles and fill them each with a skittle color, and fill the rest of the bottle with Vodka.
Now we wait from the skittles to dissolve completely.
Strain the dissolved foamy mixture using a paper kitchentowel into another bottle.
( i have 6 bottles, 5 for each color skittle and one to transfer one to the other )
Sometimes i’ll do it a second time, to get a clearer result.

Ready to drink

Most of the times, i take a longdrink glass, pour some skittle vodka in it add ice and fill the rest with 7-UP.
