Editor’s observe: One of many many lovely issues about brewing beer is that it’s rife with alternatives for experimentation, as is evidenced by the 400+ xBmts we’ve accomplished right here at Brülosophy. Whereas our focus has been totally on commonplace brewing processes and elements, there’s an entire world of unconventional variables which have but to be tapped. Such is the case with this xBmt evaluating a beer made with water to 1 made with, of all issues, a sugar-free sports activities drink. Certainly, it’s by no means been our intention to affect the best way brewers do issues, however fairly present content material that’s each informative and entertaining. Suffice to say, this xBmt lands squarely on the leisure finish of the spectrum, and we expect that’s fairly cool!

The recipe for beer is deceptively easy with solely water, grains, hops, and yeast because the 4 main elements. Small changes in these 4 variables and the strategies of mixing them may end up in drastic modifications between beers. Whereas actually a whole bunch of commercially out there varieties (if no more) of grain, hop, and yeast varieties exist as choices from which brewers can select, the adjustment of brewing water lies on a way more, fittingly, fluid scale. The qualities of brewing water first rely upon the character and geographic location of the water supply, after which may be infinitesimally adjusted by different additions of minerals and chemical compounds. A beer brewed with all the identical processes and commercially out there grains, hops, and yeast may range dramatically by location and the addition or omission of a spoonful of salts.

Whereas water high quality and profile actually have an effect on a beer’s traits, the dialogue is normally restricted to the presence or absence of comparatively small quantities of compounds dissolved within the water. A lot much less analysis has been carried out on the consequences of drastically altering the profile of a water to the diploma that it turns into marketed as a brand new liquid solely. The sports activities drink market is valued at practically $30 billion yearly worldwide, however unusually these drinks (that are largely comprised of water) not often make the elements record when designing and brewing a beer. This absolutely represents an incredible untapped market and a subject of research wealthy with potential.

I’ve loved beer for round ten years and have been brewing my very own for many of that point. My spouse doesn’t like beer. There are a handful of beers she doesn’t hate, however none that she would drink for enjoyable. My spouse likes blue Powerade Zero and will drink a bottle of Blue Moon with out horrible discomfort. As a house brewer I naturally requested myself if I may make a Belgian wit changing all water with blue Powerade Zero, if this variable can be noticeable within the ensuing product, and if she (or anybody) would really like it.

| PURPOSE |

To judge the variations between a Witbier made with water and one made with Blended Beer Powerade Zero.

| METHODS |

I modeled this recipe off a Blue Moon-type Belgian wit, as that beer is palatable to my spouse, satisfying to me, and suits with the “blue” theme of this venture.

Lavatory Water

If I’m going to try an I’ll-advised venture, I’m going to do it proper. Step one on this questionable journey was to have my residence water profile professionally examined, and have the identical firm identically take a look at a pattern of blue Powerade Zero so I can set up a baseline. The outcomes have been telling.

Whereas there have been many minor variations within the brewing salt content material in each “water” sources, there have been 3 notable variations between my faucet water and a zero-calorie sports activities drink marketed to athletes by a beverage producer. The primary 2 went hand-in-hand– notably excessive ranges of sodium and chloride, the 2 minerals that make up desk salt. Salt is an electrolyte, and sports activities beverage recipes are overloaded with electrolytes that athletes (and generally maybe crops) supposedly crave. Each sodium and chloride can individually impression the perceived flavors from different elements within the beer, and may understandably contribute to a salty taste when added in conjunction.

A much less anticipated distinction between the 2 fluids was the pH. Whereas my residence faucet water sat at an inexpensive pH and may very well be simply adjusted, the blue Powerade Zero had an aggressive pH of simply 2.6. Yeast and enzymes essential to brewing processes would discover such an acidic pH hostile at greatest, so I made up my mind the most effective plan of action was to lift the pH till the extent was inside an appropriate vary for brewing.

Preliminary analysis confirmed a couple of notable choices for pH adjustment, which I examined out in small batches weeks earlier than brewing to see which confirmed promise.

First, I attempted a product that promised to maintain your mash at a pH of 5.2 with a meager addition. In equity to this firm, I don’t assume that is practically what that they had in thoughts. In observe, I used 60x the beneficial dose to succeed in 4.3 pH, which amounted to 12 tbsp in a gallon of Powerade.

4.3 pH

Extra drastic and cost-effective measures have been clearly required. Subsequent, I attempted including powdered chalk (CaCO3), which is usually not an efficient option to increase pH resulting from its restricted solubility in water. To my shock, after including simply 2 tsp of chalk to a bottle of Powerade Zero, the pH raised to a really manageable 6.0!

6.0 pH

The answer began very cloudy, and when it will definitely settled, I seen a layer of powder on the backside of the answer that didn’t style chalk-like.

I consider the preservative acids within the beverage mixing with the chalk neutralized the acid, thus balancing the pH and leaving the white powdery precipitate on the backside of the answer. I ran a number of additional checks to find out the best amount of chalk so as to add per gallon of Powerade Zero, however at a sure level, the quantity of chemistry and stoichiometry required to pinpoint a goal pH was past my functionality. In the end, I made a decision the best option to match the batches was to roughly modify the Powerade batch to a manageable pH stage then match the extra simply adjustable water batch to the ensuing pH of the Powerade mash.

Primarily based on many small batch checks I made a decision on a ratio of seven grams of chalk per gallon. A number of hours earlier than brewing the blue batch I added my beginning quantity of 1192 ounces (9.3 gallons) of blue Powerade Zero to a sterilized mash tun and combined in 65 grams of chalk, stirred vigorously, and left it to take a seat so the answer may stabilize and the precipitate may settle out.

Within the meantime, I weighed out my grains for each batches. After roughly 3 hours, I transferred the pH balanced strike Powerade to a clear mash tun, forsaking the sediment, and heated it to my goal temperature.

I added the grains and began the mashing course of. A pattern of the wort at this level confirmed a pH of 5.6, which was slightly larger than I anticipated, however actually within the manageable vary.

5.6 pH

The mash temperature landed slightly below my goal temperature, which I blame on the unknown particular warmth of Powerade Zero.

For the water batch, I collected and heated the strike water, measured out and added my brewing salt additions to realize my goal mash pH of 5.6, then added the grains. I made a decision to regulate my goal mash temperature to match that of the Powerade Zero mash, as I wished to stop including any extraneous variables to the xBmt.

From this level on, each batches adopted the identical routine and have been handled as identically as potential. I used to be in a position to inform a definite distinction in colour between the 2 batches all through the remainder of the method. After mashing for the allotted time, I eliminated the grains, measured the the pH and temperature of each batches, then transferred the worts to separate boil kettles. As they have been heating up, I measured out my hop, orange peel, and coriander additions for every batch.

Each batches have been boiled for 60 minutes with additions made on the corresponding instances.

The worts have been cooled and transferred to sanitized fermenters.

Hydrometer measurements confirmed the Powerade batch was 0.002 OG larger than the water batch, which was anticipated as a result of the unadjusted Powerade Zero measured 0.002 SG factors larger than my faucet water in earlier checks.

Left: Powerade 1.054 OG | Proper: water 1.052 OG

With each batches chilled, I pitched the yeast, opting to overpitch as I wasn’t positive what impression the Powerade Zero would have on yeast well being and didn’t need to take any possibilities.

The beers fermented at 68°F/20°C for 18 days, at which level I took hydrometer measurements exhibiting the Powerade Zero beer completed barely larger than the batch made with water.

I proceeded to chilly crash the beers for 36 hours earlier than racking every to sanitized kegs. Apparently, it appeared the yeast and trub absorbed lots of the colour from the Powerade Zero.

The crammed kegs have been positioned in my kegerator the place they have been left to carbonate and situation for 3 weeks earlier than they have been prepared for analysis.

| RESULTS |

A complete of 19 folks of various ranges of expertise participated on this xBmt. Every participant was served 2 samples of the beer made with Powerade Zero and 1 pattern of the beer made with water in opaque cups then requested to establish the distinctive pattern. Whereas 11 tasters (p<0.05) would have needed to precisely establish the distinctive pattern with the intention to attain statistical significance, all 19 did (p= < 0.000001), indicating individuals on this xBmt have been in a position to reliably distinguish a Witbier made with Blended Berry Powerade Zero from one made with water.

The 19 individuals who made the correct choice on the triangle take a look at have been instructed to finish a quick choice survey evaluating solely the beers that have been completely different. A complete of 5 tasters reported preferring the beer made with Powerade Zero whereas 14 stated they appreciated the beer made with water extra.

My Impressions: Out of the 7 semi-blind triangle checks I tried, I accurately recognized the odd-beer-out each time. I perceived the Witbier made with Powerade Zero as having a mix of candy, tarty, and fruity flavors that really labored pretty properly, although the factitious sweetness was a bit too robust for my liking.

| DISCUSSION |

All individuals, myself included, discovered it fairly simple to inform the distinction between these beers, even when individuals weren’t permitted to look at the colour of the beers. Given the unconventional nature of the xBmt, that didn’t come as an excessive amount of of a shock. What I discovered extra shocking was the perceived variations and private impressions from individuals. Tasters described the Powerade beer as fruity and tart, they usually had problem articulating the artificially candy taste, generally describing it as butterscotch or SweeTARTS. Whereas some discovered it disagreeable, others thought it was “surprisingly good,” “completely different, however not in a nasty manner,” and “it doesn’t style like all beer I’ve had, and I don’t actually like beer, in order that’s good.”

The actual fact solely 5 of the 19 individuals most popular the Powerade Zero beer could merely mirror poorly on my selection of associates and tasters, as I feel the extra seemingly clarification is that this unusual beer had some fascinating flavors in it. Whereas I discovered the factitious sweetness to be a bit overpowering, and the colour not one thing I’d normally attain for, flavors like tart, candy, and fruity have their place within the beer world – that is simply combining them in a brand new (visionary?) manner.

My preliminary focus was to create a beer in a mode my spouse didn’t hate, utilizing a sports activities drink she appreciated. She knew the character of the venture – it’s laborious to cover that a lot Powerade Zero – and helped me doc the method, so she was not one of many official tasters. She reported liking the beer higher than she anticipated to, however nonetheless didn’t like it. The sweetness was too robust for her as properly, and he or she really stated she most popular it combined with the common beer to reasonable each flavors, which I agree with. Would I drink this specific beer recreationally? No. However over 1 / 4 of individuals most popular it over the model made with water, and some folks even went again for seconds, so clearly some would.

I’m an enormous fan of unconventional flavors in beer, and roughly half of what I brew is with the intent of making beers with traits I can’t readily discover in shops. Whereas this particular mixture may not be one I’ll replicate, it confirmed sufficient potential to make me consider within the thought behind the beer.

It’s value noting that this text glosses over a lot of the background work that was completed in designing this experiment and understanding the character of the beast I’d be utilizing to switch water. Along with these two batches of beer, I brewed a 3rd equivalent batch utilizing water however matching the water profile to that of the Powerade, to counter all of the naysayers who would absolutely attempt to declare the distinction in water profile was the true offender in perceived distinction. It wasn’t. Whereas I couldn’t persuade as many tasters to take part in one other spherical of triangle checks, the distinction in taste was nonetheless very evident as anecdotally agreed by all concerned. Aspect observe– I fairly loved the salty kick imparted by adjusting the water profile on this third batch.

There was additionally a smaller fourth batch made with a 1/6 scale recipe with out adjusting the pH of the Powerade Zero, to higher perceive what would occur to the yeast and enzymes in that surroundings. The addition of grain introduced the pH of the mash as much as 4.3, so not as hostile to yeast as I had feared, and the beer ended up fermenting to primarily the identical last gravity as the opposite batches, although did appear to have a couple of completely different flavors from the pH balanced Powerade batch. This was all along with a number of different gallon-sized or smaller checks on how completely different chemical compounds and processes affected Powerade Zero’s chemical and taste properties. I misplaced depend of what number of gallons of Powerade I ended up exhausting on this course of, however it was much more than what’s pictured right here:

Whereas a lot analysis has been completed on the impact water profile has on a beer, a lot much less is thought in regards to the results of changing brewing water with different liquids. Primarily based on this single xBmt, which to my information often is the first of its nature, it seems utilizing a liquid that isn’t water to brew a beer has a noticeable final result on the ultimate product. Is extra analysis wanted? Frequent sense would possibly counsel that it isn’t, however the scientific technique dictates in any other case. What if this xBmt have been repeated with a darkish beer? A special taste of sports activities beverage? A special beverage solely, like a delicate drink? The thoughts boggles with potentialities. I hope others will take inspiration from my preliminary analysis and work to broaden this subject to discover the myriad flavors that could be unlocked via mixtures brewers by no means dared to strive.

I could someday return to the world of unique water replacements and sports activities beers, however in the meanwhile, my palate and checking account will profit from a return to the acquainted waters of, properly, water for brewing. Primarily based on the findings of this xBmt, I truthfully consider there’s a scrumptious taste mixture on the market from changing water with simply the precise beverage in simply the precise recipe, I’m simply ready for somebody to be daring sufficient to find it.
