BLUEBERRY.BOUND

A week ago I added Sparkolloid Powder to my blueberry wine must. This blend of crab-friendly clay and polysaccharides sunk the floating yeasts and blueberry bits by positively charging them. Now three inches of detritus and less than a gallon of clear blueberry goodness remain.
Time to rack the good from the ugly. The somewhat drinkable from the undrinkable...and purple...
Not bad. But another racking is on order.The temperature breaks record this week. Granted it was only 95F, but in the North East that matters. Wine with loitering yeasts could restart fermentation or simply spoil.

The vast universe of tank air-space also worries me. Every day I spray Private Preserve to protect the wine from oxidizing. But I have no clue how long that blanket of inert gasses will hold.

Impatient, I set up to bottle.
Last time, I filled twenty six bottles. Six months on, I still have twenty. It is not every day you want to guzzle pink colored, banana-strawberry flavored welches with alcohol.

This time I scrounge about for half bottles. A gallon will fill ten 375ml bottles. Hopefully, I can also get rid of some wine as gifts. I mean, gift away my hand-harvested blueberry gold to a deserving few.
Once everything is sterile (including myself), I try racking the wine into bottles alone. I fail. So, I grab my spouse from dinner preparation.

I will pump. She will take on the tube's end, which, annoyingly, will not fill unless pressed at the right angle, under pressure, into the bottle. The siphon trigger cannot work unless against a flat surface, and most bottle punts (bottoms) curve.

So, with wife hating me, we begin.

The must remains hazy. This is annoying. I should have racked again. Maybe filtered. Most Americans view hazy wine as faulty. No one really wants to decant and let the sediment settle for a half hour or more. Conditioned by fast food, year-round strawberries, and driving to our mail box, we want immediate satisfaction. Allowing a wine to rest postpones enjoyment, unbearably for some.

But I have to stay true to the fruit. In bottle, a bit of lees (skins) will continue to contribute to the evolution of the wine's character. Filtering would remove that.
With three regular bottles (750ml) and three splits (375ml) brimming with blueberry, we taste what wine is left.

The color is of mild intensity, ruby with a slight haziness. The nose has light intensity of tart cherry, apple, clay and some sulfur. On the palate it is dry, with medium to high acidity, light tannin, light body, short length. Flavors of green and red apple (malic acid), wild strawberry, kiwi and a touch of sulfur slide by the palate in one note.

Decent and drinkable. I should have extracted more color and flavor by not bagging the skins and instead punching them down during fermentation. More time on the lees after fermentation would have also added more complexity. I also should have avoided the temptation to chaptalize (adding sugar to up the alcohol). Stupid internet advice.

Most fruit wines lack acidity and have little shelf life. Thus the blueberry acidity will help the wine age. The hint of sulfur lingers from using too many campden tablets for so little must. My frantic fear of spoilage will help preserve the wine in the long run.

It seems odd that my wine does not taste like blueberries. However, most wines do not taste like grapes. They taste of the process: the added acidities, oak, yeast strains, microxygenation machines, and chemical tweaking. I realize that blueberry "flavored" wines and beers that I have had use blueberry concentrates, distillates, or worse, chemical blends like ethyl safranate, butyl-2-butenoate, and ethyl-3-hydroxybutyrate. Yum!

Regardless, my bottles need corks. Time to give them one last inert gas spray and cork them.

With the bottles corked, I rest them sideways to ensure the corks get properly moist. Otherwise, air could get in or wine could leak.
A week later I cap the bottles with remaining foils from my kit. No nibbling mice or bunnies will eat my corks...this time. Some sediment survived the racking, but we could all use a little more patience. Decanting or just pouring slowly would suffice.In the end, going from fruit to ferment to fining to finishing was plain scary. So much more could go wrong compared to kit wine. This was not a sterilized bag-o-juice, chemically balanced to perfection and paired with packets for each step.

With more involvement and knowledge about your source materials, the harder it becomes. Picking the berries by hand forced me to worry about every detail. I had to choose between different berries, yeast strains, cleansers and fining agents. I took it personally when fermentation would not start. I rinsed equipment religiously, until the rotten-egg reek of sulfur went away. I sulked around the house for days concerned about adding sugar, water or acids. Every choice seemed wrong.

Yet every thing worked out.

FOMENTING FERMENTATION

After a week of work and wait, I prepared for the first fermentation. Step 1: clean like crazy. After a heavy wash of all the equipment, I mixed water and sulphite powder. After fearfully reading and rereading the packet, I stuffed my nose and covered my eyes. Gloves would have been nice, but lacking a biohazard suit I cleaned carefully.
After a fervent rinsing/not bursting into flames, I left the equipment out to dry. Impatient, I poured over the instructions. The translation from Quebecios French was shaky but I had bigger worries.
The linger of sulfur sent me back to the bathtub.With equipment drying again, I lined up the usual chemical suspects.
First to go in, Bentonite, the clay of kitty litter fame.The single page of instructions wouldn't assure me why I wanted cat-tasting wine, so wikipedia came in handy. Supposedly, Bentonite has cleaning and bonding qualities perfect for drawing out unwanted proteins and haziness. However, my instructions asked for "2 litres of warm water". That's a lot of water for 23 litres of wine. So I checked the French, and behold, "500 ml (2 tasses) d'eau tiède".
Once the litter was stirred to near-lumplessness, I grabbed my bag o must and dumped it in. Welches and berry scents wafted into the air but luckily not onto the carpet.
Next came the hydrometer to test the specific gravity/sugar content/brix of the must. Packlab did their job, balancing mother nature to a near perfect 1.080. This is a big deal because the sugar in grapes will become alcohol. Not enough sugar means hungry yeast. Hungry yeast means no alcohol. Which means no wine, just yeasty, kitty-litter-y grape juice.
Next up: bread-making.
Adding yeast is cheating and sacrosanct to some winemakers, who believe in letting the naturally occurring yeasts in the grape skins to turn the sugars into alcohol. Yet most add Mr. Pasteur's genius stroke without blinking (and occasionally forget to filter them later).
So I added yeast to warm water (from, well, my coffee maker). While waiting for them to wake, Alton Brown will catch you up on these guys. My dehydrated yeast fungi zombies from Champagne should thus be resurrected with a little wet warmth. They may not absolve my sins, but once reborn will turn sweet into heat.So I set the timer and went back to staring at the yeast. Nothing. Maybe now? No. Ten minutes later? Nope. But then...thanks entirely to my mind meld...


IT'S ALIVE!!! The air became heady and bready. After stirring it vigorously into the grape must, I clamped the airtight lid onto the food safe trash can, accidentally jammed the grommet into the juice with the airlock and then proceeded to ignore the problem by tasting the leftover juice:

Appearance: clear, ruby, medium intense color
Nose: clean condition, medium intense aroma, grape juice and red apple notes
Palate: high sweetness, low acidity, light body, light tannin, forward blueberry preserves, blackberries, medium length, quality...um juice?

Now the five day wait begins!
