Overall Impression: A malty but hoppy beer frequently with chocolate and caramel flavors. The hop flavor and aroma complements and enhances the malt rather than clashing with it.
Aroma: Moderate malty-sweet to malty-rich aroma with chocolate, caramel, nutty, and/or toasty qualities. Hop aroma is typically low to moderate, of almost any variety that complements the malt. Some interpretations of the style may feature a stronger hop aroma, an American or New World hop character (citrusy, fruity, tropical, etc.), and/or a fresh dry-hopped aroma (all are optional). Fruity esters are moderate to very low. The dark malt character is more robust than other brown ales, yet stops short of being overly porter-like. The malt and hops are generally balanced.
Appearance: Light to very dark brown color. Clear. Low to moderate off-white to light tan head.
Flavor: Medium to moderately-high malty-sweet or malty-rich flavor with chocolate, caramel, nutty, and/or toasty malt complexity, with medium to medium-high bitterness. The medium to medium-dry finish provides an aftertaste having both malt and hops. Hop flavor can be light to moderate, and may optionally have a citrusy, fruity, or tropical character, although any hop flavor that complements the malt is acceptable. Very low to moderate fruity esters.
Mouthfeel: Medium to medium-full body. More bitter versions may have a dry, resiny impression. Moderate to moderately-high carbonation.
Comments: Most commercial American Browns are not as aggressive as the original homebrewed versions, and some modern craft-brewed examples. This style reflects the current commercial offerings typically marketed as American Brown Ales rather than the hoppier, stronger homebrew versions from the early days of homebrewing. These IPA-strength brown ales should be entered in the Specialty IPA as Brown IPAs.
History: An American style from the modern craft beer era. Derived from English Brown Ales, but with more hops. Pete’s Wicked Ale was one of the first and best known examples, and inspired many imitations. Popular with homebrewers, where very hoppy versions were sometimes called Texas Brown Ales (this is now more appropriately a Brown IPA).
Characteristic Ingredients: Well-modified pale malt, plus crystal and darker malts (typically chocolate). American hops are typical, but continental or New World hops can also be used.
Style Comparison: More chocolate and caramel type flavors than American Pale or Amber Ales, typically with less prominent bitterness in the balance. Less bitterness, alcohol, and hop character than Brown IPAs. More bitter and generally hoppier than English Brown Ales, with a richer malt presence, usually higher alcohol, and American/New World hop character.

Proportion of LME around 67% of total Malt (it was used 3,5kg of LME, considering 1,0 kg of LME is equivalent to 1,3 kg of Malt it reaches 4,5kg of Malt)
Roasted Barley supplier suggestion maximum 5% of the total
White table sugar to increase OG and give to the final beer a dry aspect
Ale yeast SafALE US-05 (10g maybe not enough for 25 liters of wort)
Hop Columbus from Germany
Experimental - Lama for the previous brewing used additionally for fermentation
6 liters for mashing, sparge and boiling (considering evaporation)
Experimental - 23 liters of cold water at around 5°C for cooling after boiling. (No cooling process with chiller or spiral serpentine).
Maximum SRM for Beer = 40
Water Characteristics
Mashing 4 liters of all grain (1,25 kg). 3,2 liters of water per kg of Malt (grains)
3 steps of temperature
43°C - Acidification Stop (20 minutes)
62°C - Maltose Rest (20 minutes)
72°C - Sugar Rest (20 minutes)
Add enough water during sparge to reach 5 liters and start boiling.
Add hops and boil for 60 minutes.
Turn off the heating, add the sugar and cold LME (water temperature should decrease to around 50°C and volume should reach 9,5 liters.
Add around 15,5 liters of cold water (at 5°C) to reach 25 liters of wort at 20°C.
Add the yeast.

After adding cold LME and sugar, add around 15,5 liters of cold water (at 5°C) to reach 25 liters of wort at 20°C.

10g of SafALE US-05 (ale)
9 to10 days at 20°C to 22°C (until air lock stop bobbling or 3 days with same FG)
4 to 5 days at 2°C to 4°C
ABV% = (OG-FG) x 131,25
ABV% = (1,065-1,012) x 131,25
ABV% = 6,9%
Initial Water/Grist Concentration: 3,2 l/kg
Mashing with only 4 liters of water
Sparge done with water at 78°C. I am not sure if the 5 liters was reached for the pre-Boil planned wort volume.
Cold LME, sugar and cold water added right after boiling
Measured @ 73°C (14 Plato = 1.057)
Calculated to 20°C = 1,079 SG
(without LME and sugar)
Pre-Boiling
Planned SG = 1,055
Measured SG = 1,079 (much higher than estimated)
Possible reasons:
The sparge water was not enough to reach planned 5 liters (high chance)
Assumed deviation of the values for the Potential Malt SG (low impact)
Higher Mashing efficiency (low chance)
Original Gravity
Measured at 27,0°C (20 Plato = 1.083)
(+ 3,5 kg LME + 1kg sugar + additional 15 liters of cold water at 5°C)
Total wort volume 25 liters
OG calculated to 20°C = 1,085 SG
OG
Planned OG = 1,055 ( (max 1.065)
Measured SG = 1,085 (much higher than estimated)
Possible reasons:
Assumed deviation of the values for the Potential Malt SG (low impact)
Brewhouse efficiency higher than 80% (low chance)
OG adjustment (adding water) was not done.
SG1 @ 28,8°C
3rd day
(air lock w/o activity)
14 Plato = 1.057 SG
SG2 @ 29,1°C
4th day
(air lock w/o activity)
5 Plato = 1.020 SG
SG3 @ 29,9°C
5th day
(air lock w/o activity)
5 Plato = 1.020 SG
SG4 @ 28,8°C
6th day
(air lock w/o activity)
14 Plato = 1.057 SG
Fermentation temperature = room temperature = 28°C to 30°C
OG (20°C) = 1.085 SG (Jul 15th 2022)
--> 3rd day - the air lock was already without activity
SG1 (20°C) = 14,5 Plato = 1.059 SG (3rd day)
SG2 (20°C) = 5,5 Plato = 1.022 SG (4th day)
SG3 (20°C) = 5,5 Plato = 1.022 SG (5th day)
SG4 (20°C) = 5,5 Plato = 1.022 SG (5th day)
Looks like the SG is stabilized (3 consecutive)
FG (20°C) = 1.020 SG (Jul 25th 2022)
ABV % = (OG – FG) x 131,25
ABV% = (1.085-1.022) x 131,25
ABV% = 63 x 131,25
Visually the fermentation and mud seem to be ok.
FG 1.020 higher than estimated (1.012). Probably due to the small quantity of yeast (10g) for 25 liters and high OG (1.975) wort.
The beer was bottled in 5 litters mini Kegs, in total 5 mini Kegs (25 liters)
In 2 of them I put a 75 ml filtered coffee.
In 1 of them I put 75 ml filtered coffee + a bag with 5g of Mate Tea.
In 1 of them I put 75 ml filtered coffee + 2 tea spoons of Whey Protein.
In 1 of them there is only beer inside.
all Kegs have 25g of sugar (priming).
In the table (below) it is shown what is the content of each keg.
Very difficult to say exactly the EBC/SRM.
The targeted SRM was 5, that means EBC around 10.
The estimated SRM was 6,3 and EBC was 12,8. Already higher than targeted.
Visually I would say SRM between 8 and 13 or EBC between 16 and 26.
It means, double of the target.
Based on the table below we should decrease the quantity of Wheat Caramel or Caramunich II.
