#pyrazine

[great-and-small]

I've had 3 ants at a time in my bathroom for weeks now. Only ever 3 at a time. No more. I haven't bothered killing them and I have no idea why they're here or why there aren't more. They always waddle around in the same spot, the side of the bathtub. They don't even do anything. What do they want from me?

As many people are aware, ants communicate in large part via chemicals called pheromones, which can be used to signal other ants to food and nest sites. One of these chemicals is called pyrazine, and it’s a very commonly used pheromone in ant to ant communication. Funny thing is, this chemical is an organic and very aromatic compound that is also commonly used in soaps and lotions. When combined with water, the pyrazine in your soap can broadcast to ants and I’m just kidding that’s all lies I have no idea why the ants have chosen your bathroom to convene. Perhaps these three buddies share an appreciation for the human form.

Hi!! First: congrats on becoming a sommelier! And relatedly, for the three q’s meme, in your opinion:

1) Best bottle of white and/or red under $50

2) best bottle of white and/or red under $30

3) the wine that’s tickling your fancy the most right now

Thanks! And god, it’s so hard to single it down to best, but here are some that I’m loving right now!

1. Under $50

2020 Au Bon Climat Sanford & Benedict Vineyard Pinot Noir, Sta. Rita Hills, California

As a general rule, I don’t think you can ever go wrong with Au Bon Climat. A truly iconic winery founded by the legendary Jim Clendenen, Au Bon Climat has been instrumental in influencing the style of California Pinot Noir away from the overly jammy and blowsy big fruity alcohol bombs to something a lot more refined and elegant, similar to those made in Burgundy. In fact, Au Bon Climat is the only winery where I belong to their wine club and get regular shipments, all because I’ve never had a wine I’ve disliked from them, but I have had many I love. They’re my go-to for introducing someone to getting more serious about wine, and this particular Pinot is a beautiful example from a famous vineyard in Sta. Rita Hills, Sanford & Benedict, and from a parcel of vines over 50 years old, imparting a ton of flavor and character. I get notes of cherries and rosemary from this.

2. Under $30

2022 Greywacke “Wild Sauvignon” Sauvignon Blanc, Marlborough, New Zealand

I’m a complete slut for New Zealand Sauvignon Blancs. Truly, they are just SO fucking good. Sauvignon Blanc is such a fun vibrant grape and the NZ climate brings out the best in it, with a moderately cool climate that preserves the acidity well, but also with a lot of sunlight that brings out notes of tropical fruit, green bell pepper, and jalapeño. (One of my favorite wine facts is that Sauvignon Blanc grapes have pyrazines, which are the same aromatic chemicals that give bell peppers and chili peppers like jalapeño that characteristic green vegetal flavor. So there’s a good reason you’re tasting these things in wine, even if the peppers have never been in the wine! Science, baby!)

My current favorite is 2022 Greywacke “Wild Sauvignon” Sauvignon Blanc, Marlborough, New Zealand. It’s vibrantly green and lush and tastes almost athletic to me. Lots of papaya and green mango, something grassy and herbal, this is a perfect summer wine. I like to bring it down to the beach near my dad’s place and just drink it all day at the lake. I think Total Wine frequently carries this, so it shouldn’t be hard to find.

3. Wine tickling my fancy most!

2019 Left Foot Charley, “Gitali” Blanc de Blancs, Old Mission Peninsula, Michigan

If there’s something to know about me, I’m deeply passionate about Michigan wines. Michigan is where I grew up, not far from the Fennville and Lake Michigan Shore AVAs (American Viticultural Areas) and all of this pursuit of wine knowledge is in the hope of starting my own vineyard and winery there. Michigan has always had some great sleeper wines that you can get for a goddamn steal, since many people aren’t aware of how good they can be (to be fair, there is also a lot of really really bad wine), and Left Foot Charley is one of my two top favorite producers in the state (the other being Mawby). These two producers are really serious winemakers and they fully believe that Michigan is ideally situated for becoming the sparkling wine capital of the U.S., something I fully agree with and support. That said! This is a really delicious dry sparkling wine made from Chardonnay and in the traditional method, which is the same method used in making Champagne. The bubbles are very delicate, small, and explosive, and it has beautiful notes of yellow apple, toasted brioche, and yellow cherry.

213.157 Art Lab Exhibition Review and Report

Exhibition: Anti-Reality Perversion Void

Brief description of artwork presented and its method of presentation.:

This art exhibition was curated by Jess Johnson. She got together a team of ceramic artists to produce works surrounding the idea of creating an alternative reality all within their own individual artwork. Walking into the exhibition, it is very dark compared to the ‘white art gallery’ look. This makes it feel like you walk into a completely different area or reality from the rest of the gallery and exhibitions. Ceramics like clay, ash, porcelain, platinum and gold.  The mural was hand drawn, but then digitally produced. This exhibition also plays with scent, having a custom-made smell that shifts overtime with feline and floral tones. I am particularly interested in two artists, Nathan Taare(mushroom ceramics) and Jess Johnson(mural).

Analysis of impact of the artwork:

I read this exhibition as a distortion of reality, where abnormal behaviour is welcomed. It feels like a playground of work where reality simply crumbles down and those social pressures are lifted (emphasised by the 3D Jenga blocks on the mural, falling, compared to the 2D subjects.) My peer pointed out, the colourful mushroom ceramics looked like playdough, stuff we would make when we are kids. An alternate reality where we can escape adulthood, return to childhood where social expectations are gone, a space to be free to who you are. I also see this in the mural, with many humanoid figures having masculine bodies with female parts, or animalistic heads, tentacles or other abnormal features. There are also many sexual themes in the mural, which I perceive as a safe space to explore sexuality and be playful without the consequences or judgment of the public eye. I also want to mention, the smells of this room. The ingredients used are very earthy; cedarwood, amyris oil, earth pyrazine etc. I link this to that idea of playing in the dirt as a child. Scent is a strong connection to memories so the artist maybe trying to rekindle those childhood memories.

Evaluation of relevance to your practice:

These ideas draw me back to my visualization of myself through the TV Head. A screen can make us feel like we travel to different realities, whether its social media, video games, movies etc. A screen, the gateway to the internet, where anything is possible, people can be whoever they want. Where I go to be whatever I want. The TV covers that symbolism and I feel ties nicely with the ideas of this team of artists, especially Jess’s mural. I also feel that as a ‘TV Head’, I lose human qualities due to the lack of human facial features. I feel like that strip me of human responsibility. I am just a TV Head. That idea is almost freeing, because when I see my face, I see someone who has expectations, whether its my own or outside of my control. Overall, I carry the idea of social freedom, and that’s what I read from this exhibition.

Le Macchiole 2014 Paleo Rosso

Floral and vivid with striking focus. Wastes little time to strut its aromatic stuff which rivals the knockout ’15 Testamatta. Just a hint of mild pyrazine to soaring red fruit. The antithesis of grabby, more-is-more ’04 Solengo before it. Precise, suave yet light-footed with rich textural fibre, beautiful acidity and silky fine tannins. So impeccably balanced it makes you wonder "what new oak?" Inviting, drinks like an elegant brunello. Classy!

Another gem from a so-called dud vintage after ’14 Galatrona. — ★★★★

Appellation: Toscana Rosso Region: Bolgheri, Toscana, Italy Subzone: Cépage: 100% Cabernet Franc Abv: 14.5% Production: 25,000 (2016) Élevage: 18 months in barriques, 75% new and 25% second passage Distributor: n/a

[broken-moss-creature]

🐞 do you have any facts for these guys

I was actually talking to pat about these the other day lol. Ladybugs, when scared, produce a chemical called pyrazine that kinda smells like rotting flowers or leaves. Also, they were one of my favorite bugs as a kid :3

White Mist

A ridiculously clean, vibrant version of the variety, which–as usual with Sauvignon Blanc–causes me to ponder the oft-levied question: How much alleged varietal-correctness (we have somewhat erroniously learned to accept) is required in a sauv-blanc before it’s just a “nice, smooth, beautiful, white wine”? This all goes back–of course–to a *gathering* of accepted pyrazine nuances the common…

Château Pichon-Longueville Comtesse de Lalande, Paulliac 1988

February 2024 Robe has a little garnet, ruby at its core. The nose is a ballet, and a good one, mixes dots of cedar with white fennel, vanilla flowers, pyrazine, farmyard, leather, red stone fruits, and a prominent graphite minerality. The palate is one of distinction, is more on sleek lines with a firm underlay, with a good strain of fruit mid-palate before it becomes firmer. The hallmark…

The Magic of Coffee Aromas: A Journey Through Your Nose and Soul

There are over 800 known coffee aromas discovered Have you ever closed your eyes, inhaled the rich, complex coffee aromas of freshly brewed coffee, and felt a surge of pure joy? It's like a warm hug in a mug, a symphony for the senses, a little piece of heaven on Earth. But have you ever stopped to wonder, "What exactly am I smelling here?" Prepare to embark on a mind-blowing adventure with me into the world of coffee aromas, where science meets magic and your olfactory senses will do a happy dance.Imagine this: millions of tiny volatile particles, armed with their unique fragrances, are leaping from your coffee cup into your nose, each carrying a message, a memory, an emotion. It's like a secret society of coffee aromas' spies, whispering tales of the coffee's origin, its roasting journey, and its unique personality.Coffee aromas are responsible for many of the flavor attributes not directly perceived by the tongue. There are over 800 known aromatics in coffee with new ones being discovered regularly. Fresh coffee will have a much stronger aroma than older, stale coffee. Generally, as a roast gets darker, more of the compounds in coffee are changed and become detectable, meaning the coffee aromas become stronger. The process of roasting (especially to darker levels) destroys the compounds that give high-end coffee its unique characteristics and eliminates some of the benefits of paying more for coffee.However, not many people understand the science behind coffee aromas. Aromatic Adventures: A Taste of the World Close your eyes again. Is that a hint of citrus, like a mischievous sunbeam dancing in your coffee? Or perhaps a touch of chocolate, velvety and comforting like a warm hug from your grandma? Maybe your coffee whispers of distant lands, with a touch of spice that reminds you of bustling markets and exotic adventures.Coffee aromas are portals to different worlds. Light roasts sing of fresh fruit and blooming flowers, transporting you to lush coffee plantations. Medium roasts hum with nutty notes and caramel sweetness, conjuring up images of cozy cafes and friendly conversations. Dark roasts boast of smoky depths and chocolatey richness, evoking a sense of mystery and sophistication. The Science Behind the Sizzle: A Coffee Chemists' Playground But what causes these magical coffee aromas? It's all thanks to a complex orchestra of chemical compounds, each playing its tune. Imagine tiny, invisible instruments like aldehydes and ketones, composing notes of fruity sweetness or floral elegance. Acids and esters chime in with their zesty, lively melodies, while pyrazines add their earthy, smoky bass line.The roasting process acts as the conductor, shaping and transforming these notes. Lighter roasts give the spotlight to delicate, fruity tones, while darker roasts bring out the bold, smoky harmonies. It's a delicate dance of heat and time, creating a symphony of coffee aromas that is unique to each coffee bean.The coffee aromas are created by volatile compounds that are released when the coffee is brewed. These compounds are detected by our sense of smell, which is why coffee aromas are so important. Types of Coffee Aromas There are many different types of coffee aromas, and each one has a unique scent. Some of the most common coffee aromas include:- Fruity: This aroma is created by compounds that are found in fruits, such as berries and citrus fruits. It is a sweet and refreshing aroma that is often found in light-roasted coffees. - Floral: This aroma is created by compounds that are found in flowers, such as jasmine and lavender. It is a delicate and fragrant aroma that is often found in medium-roasted coffees. - Spicy: This aroma is created by compounds that are found in spices, such as cinnamon and nutmeg. It is a warm and comforting aroma that is often found in dark-roasted coffees. - Nutty: This aroma is created by compounds that are found in nuts, such as almonds and hazelnuts. It is a rich and creamy aroma that is often found in medium to dark-roasted coffees. Aromatherapy for the Soul: A Coffee Break for Your Emotions Coffee aromas aren't just a treat for your nose, they're a powerful tool for your soul. The scent of freshly brewed coffee can be instantly calming, reducing stress and anxiety. It can also be invigorating and uplifting, boosting your mood and energy levels. Conclusion So next time you take a sip of coffee, pay close attention to the coffee aromas. Notice how they make you feel. Is it a comforting hug? A burst of sunshine? A playful adventure? Let the coffee aromas guide you on a journey through your senses and your emotions. And remember, my dear coffee lover, you're not just drinking a beverage, you're experiencing an olfactory adventure, a scientific marvel, and a delicious emotional rollercoaster, all wrapped up in one beautiful cup.
