Between V1.0 and V1.1, there are very minor aesthetic differences. The V1.1 has a slightly thicker rim at the top, resulting in a very slightly larger diameter, and a different brushed finish compared to V1.0. All caps will fit on both versions, but the diameter may be off by 0.5-1.0mm with mismatched versions. Wooden caps made before March 2025 all have the smaller diameter to match V1.0. Wooden and Steel caps after March 2025 will have the slightly larger diameter to match V1.1. While V1.0 is made of SUS316, V1.1 is made of SUS304, which matches the spec of the stock hopper. \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAdding Optional Bellows Later\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eIf you already own the hopper and would like to add the optional bellows, you can purchase it separately here: \u003ca href=\"https:\/\/introvertmakes.com\/products\/silicone-bellows-for-introvert-single-dose-hoppers?utm_source=copyToPasteBoard\u0026amp;utm_medium=product-links\u0026amp;utm_content=web\"\u003eSilicone Bellows for INTROVERT Single Dose Hoppers\u003c\/a\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eDisclaimer\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eGrinding after changing grind size or using darker roasts\/oilier beans may increase retention.\u003c\/li\u003e\n\u003cli\u003eAchieve the best results with lighter roasted beans and at a consistent grind size setting.\u003c\/li\u003e\n\u003cli\u003eThis listing is for the Wide Hopper and optional bellows only.
