  1. Scottish 80 Shilling (80/-) #1

     

    17 L Batch Size

     

    2.6 kg Pale Ale (Weyermann and Fawcett's Golden Promise)

    205 g Caramel 20 L

    205 g Caramel 80 L

    165 g Caramel 120 L

    100 g Munich I

     

    30 g East Kent Golding (30 min)

     

    FM12 W szkocką kratę (Startered)

     

    Making a batch as a "starter" for a Wee Heavy. Startered FM12 at 1 liter for 24 hours. Mashed in with 12 L of water at 80 and overshot my mash temperature by 2 degrees. Added a little bit of cooler water to get down to 70, and mashed for 90 minutes due to a storm rolling through. Pulled 7 liters of 20 Plato runnings, sparged with 8 liters of cool water. Sparged one more time to volume. 22 liters of preboil volume, boiled for an hour and collected at 11.5 degrees Plato. Chilled and poured into sanitized keg to ferment. Let cool to 15 C in keg before pitching.

    Closed up the keg after 5 days of fermentation. Pressure when checked with spunding valve tight a few days later was 14 PSI. Should be around 2 volumes at the temperature it was in the cellar. First glass off showed it hazy due to how young it is, but with a beautiful malty profile. My wife would like me to carbonate it a bit higher so she'll sit on the gas for a few days then I'll probably let it sit for a bit while I work on my new apartment.

     

     

  2. Enzymów bedzie akytwny jak nie są denaturowane. Aktywność jest bardzo wolno jak jest zimno. Tylko na wysoka temperatura bedą denaturowane. Teraz coś po  Angielsku od ekspert enzymów jęczmien:

     

     

     
    Firstly, the mash must be heated to around 65°C to achieve a relatively rapid rate of starch gelatinization to enable the DP enzymes to rapidly degrade it.  However, at that temperature, depending on amount of solutes (KI, osmolyte conc, etc) and mash thickness, the enzymes (esp b-amylase and limit dextrinase) will denature.  When you cool the mash down, depending on when you do it, a proportion or all of these enzymes will already be denatured.  However, on cooling (particularly on ice, not sure of other temps), some of the enzymes that may not have been irreversably denatured, may refold (re-nature - JP) returning some of the enzymes activity.  This is the difference of the Sd1 type b-amylase thermostability compared to the Sd2H type.
     

    On cooling the mash, why you would bother(?), some enzyme may refold (?).  If it is limit dextrinase, it may reattach itself to its inhibitor (?).  The DP enzymes will be active at say 15-20°C because barley germinates and grows from the seed at this temperature.  The rate of the enzyme action will of course be slower at the lower temperature, and I would not rule out changes in the starch structure that might hinder hydrolysis.

    I assume you speak English due to the fact that you are watching American brewing videos. Denny Conn was the first brewer to begin advocating the batch sparge. This is what I do. My last brew looked like this (17 L batch):

     

    Dough in with 9 L   

    Batch Sparge with 10 L

    Batch Sparge with remainder to hit boil volume

     

    If you want to continuously sparge (fly sparge) you need ether a false bottom or a correctly designed manifold or you will get channeling and get terrible efficiency.

     

    Many BIAB brewers are doing no-sparge brewing in larger kettles. This would require probably 50-70L of kettle space. They are adding their entire liquor at the start of the mash. This changes the pH and also the enzymatic efficiency but has shown to have no ill effects if you control pH and allow your mashes to complete.

    Przepraszam bardzo, ale co to ma znaczyć, dlaczego piszesz po angielsku ??

     

     

    Bo lepiej piszę po Agielsku, i pan mówi po Angielsku. Pytanie jest na temat piwowarów Amerykanskie.

  5. Mam kuchenka indukcyjna Stalgast 3500 W, i gotuję warki 15-17 L. Jest bardzo szybko. Używam kegi do fermentacja z krótsze diptube-y. Są solidny, od stal, i mogę rozlewac do keg bez O2. Mam lodówka turystyczna i torba BIAB i cała warka była 2,5 godziny. Jestem zadowolony że zmieniłem do 15 L warki.

  6. Belgian Dark Strong Ale #1

     

    15 L Batch Size

     

    3 kg Pale Ale (Weyermann)

    500 g Carapils/Dextrine Malt

    1 kg Homemade Amber Brewer's Caramel

     

    15 g Hallertau (60 min)

     

    FM26 Belgijskie Pagórki (Startered)

     

    Wanted to try out this yeast and made some brewer's caramel to mimic Candi syrup in a Belgian-style ale. My efficiency was a lot higher than expected, so I added additional brewer's caramel to bump it up to Dark Strong Ale levels. Fermented it at high ambient (24 C) to check out the yeast at high temperatures. Came out hot and will age it as long as possible. After having some issues with adjusting my gear, and drinking a portion out of the keg, ended up with only about 8 x 750 mL bottles for aging.

     

    Brewed 07.11

  7. Amber Ale #3

     

    15 L Batch

     

    3 kg Pale Ale (Weyermann)

    60 g Pale Chocolate

    125 g Caramel 60L

    250 g CaraGold

    170 g Caramel 10L

     

    53 g Centennial (7 min)

     

    Hothead Ale by Omega (Startered)

     

    Mashed in with 12 L of water to hit a 66.5 C target mash temperature. Mashed for 30 minutes. Sparged once. Boiled for 30 minutes before chilling and putting into the keg to ferment. Fermented it at ambient for 7 days primary before racking to keg. Force carbed for one day at 30 PSI, then dropped to 20 PSI until carbonated.

    Amber #3

     
    Got this quick and dirty batch into the keg as fast as possible and straight into bottles without a prolonged cold crash or fining. Needed something to drink and wanted to check the ester produced for the yeast. Nice fruity ester was pretty front and center, complimenting the Centennial hops well. I can see myself using this yeast a lot in the future, especially due to its temperature tolerance. 
  8. Hoppy Blonde #1

     

    17 L Batch

     

    2,9 kg Pale Ale (Weyermann)

    450 g Vienna (Weyermann)

     

    50 g Amarillo (7 minutes)

     

    Aiming to use up some Amarillo with a quick brew, I mashed in with 9 L of water to hit 65 C target temperature for a 40 minute mash. Drew off first runnings, and did two sparges with cold water to hit 20 L into the kettle. Boiled for 40 minutes before chilling and putting into the keg to ferment.

     

    Brewed 04.04

    Time to brew: 150 Minutes

    Picture before and after adding gelatin for 5 days.

     

    Hoppy Blonde #1

     
    Nice light beer, typical of a blonde. Amarillo aroma and flavor are the primary elements of the beer, with a subtle bready background from the grains. Nice head leaves ample lacing and keeps a nice white cap on the beer the whole way down.
  9.  

    36+ litrów w stylu "Tadar" jest lepszy. Najlepsze garnki są wysoki.

    Wygląda solidnie. Jaka jest jego przewaga nad tureckim i ronnerem?

     

     

    Solidny, stal, konstrukcja dna typu "Sandwich", dobra proporcja Średnica:Wysokość. To tylko, moze byc tanszy jak tureckie ale bez "sandwich" nie bedzie dobra na indukcja i na start powinna byc wiecej w garnku.
