The logo appears to be a bottle of liquor. There is no letters visible , only a place for a label but nothing is readable and there appears to be a cap or cork of some sort at the top.
This is a Wine Bottle icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,900 icons, all in the same style and quality.
