📖 Essential Mt Tam Guide

🧀 What is Mt Tam?

Mt Tam (short for Mount Tamalpais) is a triple-cream soft-ripened cow's milk cheese created by Cowgirl Creamery in California. Developed in the early 2000s, it represents the American artisanal cheese renaissance, drawing inspiration from French cheese traditions while celebrating California's exceptional dairy.
There is only one type of Mt Tam, characterized by its mushroomy rind, buttery paste, and rich mouthfeel. While it doesn't come in varieties like many other cheeses, its flavor profile evolves dramatically through its ripening period, ranging from mild and creamy when young to complex and earthy when mature.

🏭 Where is Mt Tam Produced?

Mt Tam is exclusively produced by Cowgirl Creamery in Point Reyes Station and Petaluma, California. The cheese's distinctive character comes from organic milk sourced from Straus Family Creamery in Marin County, where Jersey cows graze on sweet coastal grasses influenced by the foggy maritime climate. This terroir directly translates to Mt Tam's unique flavor profile.
While Mt Tam is a specific American original, it belongs to the broader family of triple-cream soft-ripened cheeses pioneered in France and now produced globally.
Biggest Producers of Triple-Cream Soft-Ripened Cheeses
  1. France The birthplace of triple-creams like Brillat-Savarin and Pierre Robert
  2. United States Home to artisanal producers focused on local ingredients and European techniques
  3. Italy Creates rich, soft-ripened varieties with regional milk characteristics
Not all triple-cream cheeses are created equal, with quality depending on milk source, aging techniques, and producer expertise.
Best Quality Triple-Creams
  • California, USA Mt Tam by Cowgirl Creamery. Distinguished by its organic milk from pasture-raised cows and careful hand-production
  • Ile-de-France, France Brillat-Savarin. The classic French triple-cream with lactic brightness and mushroom notes
  • Burgundy, France Délice de Bourgogne. Rich and decadent with a complex rind development
The winner: Why California's Mt Tam rises above the rest lies in its perfect balance of tradition and terroir. The fog-kissed coastal pastures of Marin County create milk with exceptional butterfat content and grassy sweetness. Cowgirl Creamery's founders studied traditional French techniques but adapted them to showcase California's unique dairy quality. The result is a cheese with the technical perfection of French classics but a distinctly American personality—less mushroomy than many French counterparts, with a cleaner, more buttery profile that speaks to its Pacific origins.

📦 Mt Tam: How It Comes to You

Mt Tam is available in consistent forms designed to preserve its delicate texture and flavor:
  • 🧀 Whole Wheel (8 oz/225g) Perfect for cheese boards and special occasions
  • 🍰 Half Wheel (4 oz/113g) Ideal for smaller gatherings or cheese-loving households
  • 🔪 Cut-to-Order Wedges Available at specialty cheese shops for flexible portions
  • 🛒 Pre-Packaged Wedges Found in some upscale grocery stores, though less common

🌱 Seasonal Product Guide

While produced year-round, Mt Tam exhibits subtle seasonal variations reflecting changes in the cows' diet and milk composition:
  • 🌸 Spring Particularly bright and floral notes from fresh spring grasses; a stellar season for Mt Tam
  • 🌞 Summer Rich and buttery with slightly more intense flavors as cows graze on abundant summer pasture
  • 🍂 Fall Deeper, more complex flavor profile with subtle nutty undertones developing
  • Winter Slightly less complex but exceptionally creamy during indoor feeding months

🧐 How to Choose the Best Mt Tam

Look beyond the recognizable label and assess the cheese's condition—a perfectly ripe Mt Tam transforms a good cheese board into an unforgettable experience.
Appearance
  • Color The rind should be white to ivory without any pink, orange, or gray discoloration
  • Form Slightly bulging sides indicate proper ripening; avoid severely collapsed or overly firm wheels
  • Ripeness Some minor "weeping" at room temperature is normal; excessive liquid suggests over-ripening
Aroma
  • Mushroomy complexity Gentle earthy notes reminiscent of button mushrooms with buttery undertones
  • Balance test Should smell inviting without ammonia sharpness, which indicates over-ripening
  • Warning signs? Strong ammonia or sour milk smells suggest the cheese is past its prime
Texture
  • Yielding firmness Should gently give under slight pressure; the center should be soft but not liquid
  • Cream line A visible progression from firmer center to creamier edges indicates proper ripening
  • Warning signs? Rock-hard center (underripe) or uniformly runny texture (overripe)

👃 Sensory Profile

Mt Tam offers a sensory journey that begins with its bloomy white rind's delicate mushroom aroma. The initial taste presents rich cultured cream with subtle lactic tanginess that evolves into notes of fresh butter and white mushrooms. The texture progresses from silky at the rind to dense and fudgy toward the center, creating a mouthcoating richness that slowly melts away, leaving lingering hints of salted butter and meadow herbs.

🧭 Other Factors to Consider

When selecting Mt Tam, consider these factors to ensure you're getting an authentic, well-handled product at its peak condition:
  • Producer True Mt Tam is made exclusively by Cowgirl Creamery; verify the source to avoid imitations
  • Freshness Dating Look for clear production or "best by" dates; aim for cheese with at least a week before its date
  • Retail Environment Purchase from shops with dedicated cheese counters and proper storage conditions
  • Handling Cheese should be properly wrapped, stored at appropriate temperatures, and handled minimally
  • Price Point Quality comes at a premium; suspiciously inexpensive "Mt Tam" may be mislabeled or inferior

🧊 How to Store Mt Tam Properly

Proper storage preserves Mt Tam's delicate balance of flavors and textures, ensuring you enjoy it at its peak:
  • Whole Wheels Store in the refrigerator at 35-40°F (2-4°C) for up to three weeks
  • Cut Portions Wrap in cheese paper or parchment followed by loose plastic wrap for up to one week
  • Serving Preparation Remove from refrigeration 30-60 minutes before serving for optimal texture and flavor
  • Transportation Use insulated bags when bringing home from the store, especially in warm weather

📌 Final Thoughts on Mt Tam

Mt Tam represents the pinnacle of American artisanal cheese-making—a perfect marriage of French technique and California terroir. While many see it as merely "fancy Brie," its triple-cream richness and distinctive flavor profile set it apart from European counterparts. Historically significant as part of America's cheese renaissance, it's equally at home on an elegant cheese board, melted into a special grilled cheese, or enjoyed simply with fresh fruit and honey.
Let Mt Tam come to room temperature before serving, and you'll be rewarded with its full symphony of flavors and that irresistible creamy texture that makes it a true California treasure. 🧀

🛒 How to Buy Mt Tam: Physical & Online Shopping

🛍 What to buy

Mt Tam is the flagship triple-cream from Cowgirl Creamery (Point Reyes Station, California), so the regional variety is the variety. What changes is age on arrival.
Preferred Varieties by Region
  • Northern California Wheels trucked straight from Point Reyes: barely 3 weeks old, ivory core, faint cauliflower scent—perfect if you like a buttery fondue center.
  • Rest of USA 4–5 weeks old by the time it reaches the case: rind slightly wrinkled, interior custard-soft, more pronounced crimini aroma.
  • EU Imports Usually 6 weeks+ after export; rind may show amber speckles—still safe, but the paste will be runny and the flavor nuttier, almost Brie-de-Meaux-like.
What to Look For
  • “Cowgirl Creamery” embossed on the wooden crate or green foil under the paper wrapper.
  • Best-by date at least 7 days out—triple-creams collapse fast once cut.
  • No ammonia whiff; a faint whiff is normal, sharp cat-box smell means over-ripe.
  • Whole wheel if you can swing it; pre-wedges lose moisture and pick up fridge odors.
Use-Based Recommendations
  • Best for Raw Use A young wheel (3–4 weeks) sliced onto warm baguette—it spreads like truffle butter.
  • Best for Cooking Aged wheel (5–6 weeks) baked en croûte; the extra runny center stays molten without splitting.
  • Budget Pick “Seconds” sold at the Point Reyes farm shop—cosmetic cracks, same taste, ~20 % off.

💰 What’s a Fair Price?

  • USA: $26–32 per 10 oz wheel in specialty stores, $20–24 direct from Cowgirl Creamery online.
  • Canada: CAD $34–38 at Les Amis du Fromage or Alex Farm.
  • UK: £22–26 at Neal’s Yard Dairy or La Fromagerie; watch for “California Triple-Cream” label if Mt Tam isn’t named.
  • EU: €25–30 in Paris or Berlin, often shipped chilled from London. Anything under €20 is likely a domestic Brie knock-off.
Red flags: deep discount bins—triple-creams don’t clearance gracefully; no cold-chain sticker on imported boxes.

🧺 Local Shops & Markets

  • USA: Whole Foods (coast-to-coast), Dean & DeLuca (NYC, DC), Bi-Rite Market (SF).
  • Canada: Whole Foods (Vancouver, Toronto), Save-On-Foods (BC) in the “Artisan” bunker.
  • EU: Neal’s Yard Dairy (London), Androuët (Paris), Käsehaus (Berlin).
  • ANZ: Simon Johnson (Sydney, Melbourne), La Cigale market stall (Auckland).

🌐 Online Options

  • USA: Cowgirl Creamery’s own webstore (ships Mon–Wed with ice packs), Goldbelly, Instacart from Whole Foods.
  • Canada: Cheese Boutique (Toronto, ships nationwide), Saveur du Jour (Quebec).
  • UK: Pong Cheese, The Courtyard Dairy—both offer next-day chilled.
  • EU: Formaggio.it (ships from Amsterdam), Quirielle.de (Germany).
Search tip: try “Mt Tam Cowgirl” or “Cowgirl Creamery triple cream”—spelling variants are rare but “Mount” with a u sometimes slips in.
Tips for Ordering Mt Tam from Abroad
  • Check Shipping Costs overnight or 48-hour max; triple-creams hate Mondays in a warehouse.
  • Freshness Guarantees look for “cold-chain maintained” or “if bloomy mold turns pink we replace” policies.
  • Buy in Bulk Cowgirl ships 3-packs at a slight discount; split with friends or vacuum-seal half-wheels for 2-week fridge life.
  • Customer Reviews scan for “arrived bloated” or “rind wet”—both signs of temperature abuse.

🔄 If You Can’t Find It

Swap in Saint-André, Brillat-Savarin, or Délice de Bourgogne—all triple-cream bloomy rinds with 75 % butterfat and similar mushroom-cream flavor. For a West-Coast vibe, Red Hawk (also Cowgirl) gives a washed-rind funk but melts the same. Look for “triple-crème” on the label and aim for 200 g wheels to mimic Mt Tam’s size and ripening speed.

🧠 Deep Dive: Mt Tam Beyond the Basics

🔪 Culinary Techniques & Handling

  • Temperature Control Remove from refrigeration 30-60 minutes before serving; cold temperatures mask flavor complexity
  • Cutting Technique Use a wire cheese cutter or warm, clean knife; cut like a cake from center outward for even portions
  • Rind Appreciation The bloomy rind is edible and contributes essential flavor; avoid trimming unless personally preferred
  • Serving Caution Avoid serving on reactive metal surfaces; ceramic, glass, or wood plates maintain flavor integrity
  • Ripeness Assessment Gently press the surface—slight give indicates perfect ripeness; too firm means underripe, while excessive softness suggests overripening
  • Regional Twist In Northern California, Mt Tam is often paired with local sourdough bread and honey, creating an interplay between tangy bread, sweet honey, and creamy cheese. By contrast, East Coast cheese shops often recommend serving it with tart fruit preserves to balance its richness.

Saint André80%Similar buttery texture; less complex flavor development
Délice de Bourgogne75%More assertive flavor but comparable luxurious mouthfeel

🥂 Pairings: Mt Tam's Best Friends

Mt Tam's buttery richness and subtle complexity make it exceptionally versatile for pairing:
  • Sparkling Wine The high acidity and effervescence cut through the cheese's richness while complementing its creamy texture. Californian sparkling wines mirror Mt Tam's origin story perfectly.
  • Honey The floral sweetness creates a delightful contrast with Mt Tam's savory notes. Wildflower or orange blossom honey accentuates the cheese's subtle herbal qualities.
  • Fresh Stone Fruits Peaches, nectarines, and plums offer juicy acidity that balances Mt Tam's richness. The subtle almond notes in stone fruits harmonize with the cheese's nutty undertones.
  • Toasted Walnuts The earthy crunch provides textural contrast while amplifying Mt Tam's mushroomy qualities. The slight bitterness of walnuts highlights the cheese's buttery sweetness.

🔬 Why Mt Tam Works: The Science & The Magic

Mt Tam's distinctive character comes from its careful production process and specific microbiological development:
  • High Butterfat Content Contains additional cream added to whole milk, creating a fat content of at least 75% in the dry matter, resulting in exceptional richness
  • Enzymatic Action Penicillium candidum on the surface breaks down proteins and fats during ripening, creating complex flavor compounds and the signature creamy texture
  • Lactic Fermentation Carefully selected lactic acid bacteria develop the cheese's foundational flavor, contributing both acidity and aromatic compounds
  • Microflora Interaction The interplay between surface molds and internal bacteria creates unique flavor compounds impossible to achieve through other methods

🌍 Cultural Significance

  • American Cheese Renaissance Mt Tam represents the revival of artisanal cheesemaking in America, challenging the notion that quality soft-ripened cheeses could only come from Europe
  • Feminist Legacy Created by Sue Conley and Peggy Smith, female pioneers in a traditionally male-dominated industry, embodying California's progressive food values

  • Sustainable Packaging Cowgirl Creamery has worked to reduce plastic use and increase recyclable materials in their packaging.
  • Animal Welfare Sourced from pasture-raised cows with high welfare standards, including access to open grazing.
  • Local Sourcing By using milk from within Marin County, transportation emissions are minimized.
  • Water Conservation Straus Family Creamery implements methane digesters and water recycling systems to reduce environmental impact.
  • Community Support Cowgirl Creamery helped establish the Marin Agricultural Land Trust, protecting farmland from development.
  • Climate Resilience Supporting pasture-based dairy systems promotes carbon sequestration in grasslands.
  • Artisanal Scale Small-batch production allows for greater attention to environmental impact than industrial operations.

♻️ Sustainability Score

Mt Tam stands out as one of the more environmentally conscious cheese options available. Organic milk production eliminates synthetic pesticides and fertilizers, while pasture-based farming captures carbon in soil. The small-scale, localized production model minimizes transportation emissions. However, like all dairy products, it still has a higher carbon footprint than plant-based alternatives—about 13.5 kg CO2 equivalent per kg of cheese, roughly half that of conventionally produced soft cheeses. Consider it the Tesla of cheese: not emission-free, but significantly better than conventional alternatives if you're going to indulge your dairy desires.
