## Notes

Verified against Gaggia's official technical PDF and North America product
page on 2026-07-06. The Classic GT is the up-spec sibling of the Classic Pro:
the same 58mm commercial filter-holder standard, but shipping with
traditional (non-pressurized) 11g and 18g baskets only — no pressurized
basket in the box, unlike the Classic Pro/E24 — plus a blind filter and a
wood-handle stainless-base tamper.

  - Official Gaggia Classic GT technical information PDF, read firsthand 2026-07-06. States verbatim: 'Filterholder & filters dia. 58mm'; 'Filters included: 1 traditional double filter (18g); 1 traditional single filter (up to 11g); 1 blind filter'; filter holder material 'Stainless steel'; boilers 'Brass (Brew) / Stainless Steel (Steam)'. Traditional filters are Gaggia's non-pressurized commercial-style baskets.

  - Official Gaggia North America product page, read firsthand 2026-07-06. Lists the included '11g Single-Shot Basket' and '18g Double-Shot Basket' plus a 'Wood Handle Tamper with Stainless Base'. The page itself does not print the diameter — the 58mm figure is stated explicitly in Gaggia's tech-info PDF above.
