coffee-aficionado

A coffee expert in your Vellum assistant. Finds great beans and equipment matched to your taste, budget, and kitchen — and gets sharper over time as it learns what you actually like.

No credentials, no external API keys. Curated origin and equipment knowledge is baked in; live pricing and availability come from Vellum's built-in web search.

What it does

• Learns your taste. A persistent profile stores your preferred roasts, flavors, brew methods, budget, kitchen constraints, and equipment. Every bean you rate teaches it: 4-5 stars adds an origin to your favorites, 1-2 stars steers future picks away from it.
• Recommends beans. Scores 15 curated origins against your profile and hands back optimized web-search queries so the assistant surfaces current, buyable bags with live prices — not just origin names.
• Recommends equipment. Ranks 18 curated espresso machines, grinders, and brewers across entry → commercial tiers, matched to your budget, experience, and brew method.
• Teaches when you're curious. Two skills carry deep reference material on processing methods, roast levels, terroir, grinder types, and the upgrade ladder — pulled in only when you want to understand the why.

• "I loved that Ethiopian Yirgacheffe — 5 stars." → logged, and Ethiopia is now a learned favorite.
