Marketplace channels, Mash & Grape, ReserveBar, Caskers, when to use which?

Alcohol marketplace channels are the equivalent of Amazon for non-alcohol DTC, but split by category + price point:

• Mash & Grape, premium spirits ($40+ bottles). National fulfillment via licensed retailers. Good for craft spirits brands trying to break into national distribution. ~15-20% commission. API integration with Magento via product feed.
• ReserveBar, premium spirits + wine, often used for corporate gifting + brand websites’ "buy now" buttons. National fulfillment via licensed retailer network. ~20-25% commission. Best for brands with marketing demand they can’t fulfill themselves.
• Caskers, curation marketplace for spirits + craft beer. Editorial discovery model (featured releases, limited drops). Lower commission (~15%) but lower volume. Good for new product launches.
• Flaviar, spirits club marketplace. Subscription members get monthly tasting boxes. Producer listings via wholesale arrangement (not commission). Good for brand discovery; harder to track ROI.
• Wine.com, wine only. Massive scale (largest US wine ecom). Producer listings via wholesale. Brand-building channel; takes margin.
• Drizly + Uber Eats Alcohol + Instacart, same-day local fulfillment via licensed retailers. ~15-30% commission. Best for impulse + convenience demand.

Pattern for a $1M, $10M alcohol brand: Magento as DTC + customer-of-record + 1 spirits marketplace (Mash & Grape or ReserveBar based on positioning) + Drizly + Uber Eats Alcohol for local convenience. Don’t list on 5 marketplaces, channel conflict + inventory chaos. Pick 1-2 and own them.
