===The Creation of Grand Blu===
<blockquote>In fall of 2015, we had a hypothesis concerning Penicillium roqueforti and whether or not it would influence a beer with a distinctive Blue Cheese funkiness. Initially, we thought it may go through fermentation because it is part of the monophyletic group, ascomycetes (which includes saccharomyces cerevisiae). However, after further investigation we realized most likely any changes to the beer would be primarily enzymatic, followed by molecular conversions which may influence the sensory characteristics.''From Dennis Hock
Regardless, after outlining our goal<blockquote>In fall of 2015, we reviewed had a hypothesis concerning Penicillium roqueforti and whether it would influence a beer with a distinctive Blue Cheese production for approximately two monthsfunkiness. We realized that the P. Roqueforti Initially, we thought it may go through fermentation because it is typically added during part of the curd forming stagemonophyletic group, ascomycetes (which includes saccharomyces cerevisiae). The organism is encapsulated inside the cheese formHowever, but won’t develop after further investigation we realized most likely any changes to the distinctive veins unless a microaerophilic environment is achieved. Thus, in Blue Cheese productionbeer would be primarily enzymatic, followed by molecular conversions which may influence the wheels are “needled”sensory characteristics.
Regardless, after outlining our goal, we reviewed Blue Cheese production for approximately two months. After speaking to some cheese manufacturers, we realized that the P. Roqueforti is typically added during the curd forming stage. The organism is encapsulated inside the cheese maker takes a stainless steel rod and pokes small holes inside form but won’t develop the wheel, allowing micro-oxygenation, and creating distinctive veins unless a microaerophilic environmentis achieved. Over timeThus, the veins begin to grow and the distinctive in Blue Cheese characteristics developproduction, the wheels are “needled”.
Needling is when the cheese maker takes a stainless steel rod and pokes small holes inside the wheel, allowing micro-oxygenation, and creating a microaerophilic environment. Over time, the veins begin to grow and the distinctive Blue Cheese characteristics develop. Our next step was to attempt the same microaerophilic environment as the needled cheese wheel, only using the properties of oak casks. We hypothesized French oak would suffice, considering it’s the tightest grain of oak used in coopering. We thought the tight grain would mitigate/minimize oxidation, but allow enough micro-oxygenation that P. Roqueforti would develop.
In 2016, we inoculated a standard base beer in casks with P. Roqueforti. The base beer was mashed at a higher temperature with large quantities of oats and wheat. Our goal was to create a growth medium with the environmental conditions that promote P. Roqueforti development and subsequently residence inside the cask. This base beer was later discarded, as its sole purpose was to nourish the organism and allow the harborage of the population inside the selected casks.
When we brew The 2016 Grand Blu, it’s was brewed during our spontaneous fermentation season (Late fall through early spring) when the outside temperature is was below 47°F. Although it’s it was inoculated with our Relic strain of yeast, we open ferment fermented the batch for 24 hours. During the open fermentation, any resident micro flora, including acidification bacteria, typically join joined the fermentation festivities. At approximately 5.1°P (1.020 S.G.), we move moved the Grand Blu to the P. Roqueforti casks and wait. The P. Roqueforti development will take approximately 2-6 months and it adds a distinctive blue/green color to the pellicle. The mycelium grow in various directions, including into the sub surface, and ultimately take over any exposed pellicle resulting from wild yeast and/or bacteriawaited.
After the The P. Roqueforti has imparted its funkiness (which is subtle but both present aromatically development took approximately 2-6 months and in the flavor profile), we move it into steel and add added a distinctive blue/green color to the peachespellicle. The re-fermentation increases mycelium grew in various directions, including into the CO2 concentration sub surface, and inhibits the P. Roqueforti ultimately took over any exposed pellicle resulting from continuing to develop (at least that’s what we have experienced). When appropriate, we bottle wild yeast and mature/or bacteria.
Beginning After the P. Roqueforti imparted its funkiness (which is subtle but both present aromatically and in 2018 the flavor profile), we used moved it into steel and added the solera peaches. The re-fermentation increases the CO2 concentration and inhibits the P. Roqueforti from continuing to develop (perpetual blendat least that’s what we have experienced) method . When appropriate, we bottle and that is how we are going to continue, moving forwardmature.
Since then, we have relied on using a solera method from those original casks inoculated with P. Roqueforti and blending, before going into steel to ferment with the peaches. Grand Blu is only 2019 vintage has not been released once annually. When ready, but we are hopeful it is bottled and then will finish maturation after about 2 months timesometime in May. </blockquote>
