What are the design specifications, costs, and practical considerations for using paper bottles for spirits?

Paper bottles for spirits are an emerging sustainable packaging option, but come with significant cost and operational considerations. Here's what members have learned:

**Specifications & Performance** - **Frugal bottles** are the main provider members are using; they weigh just 81g empty and around 800g when filled (700ml), compared to 1–1.8kg for standard glass bottles - Design achieves full 360° label coverage - Manufacturing process is relatively simple, but lead times are long and often delayed

**Costs & Minimum Orders** - Minimum order quantity is 5,000 units but becomes "much cheaper and easier" at 20,000+ units - Bottle cost: approximately £1 per unit - Filling cost: approximately £1 per unit (so ~£2 total landed cost) - Printing, assembly, and pouches are provided by Frugal and completed in the UK - Final unit costs are described as "pretty high" due to the way Frugal structures its business

**Filling & Operations – Critical Challenges** - **DO NOT attempt to fill in-house.** Members who tried lost 6 months to trial-and-error; the pouch vacuum system and bottle-weighting requirements are complex - Filling is "a nightmare" and requires specialist equipment most producers don't have - **Recommended bottler: Silent Pool** — members report they have cracked the filling process and can provide filling pricing and guidance; other bottlers are being brought on board but availability is limited - Frugal's business model prioritises selling assembly machines rather than finished goods, which complicates the supply chain for smaller producers

**Strategic Use** - Members recommend paper bottles for e-commerce and D2C channels (low carbon footprint, breakage not an issue) - On-trade and retail use is still developing; retailers may prefer bulk solutions or established formats - Paper bottles are lighter, reducing logistics carbon but are single-use

**Caveats** - Lead times and delays are common; plan accordingly - Retailer pushback on alternative formats should be anticipated - Frugal is actively expanding its network of approved bottlers, so availability may improve
