Legless and confused

Maybe you need a thicker whisky?

I wash my Glencairn with soap and rinse thoroughly before drying it with either cotton cloth or microfiber. No taste of soap, and legs enough legs for everybody! Perhaps you haven't gotten your glass clean enough?

@Phil73805: Try this...Rinse the empty glass with warm water, then add one or two drops of liquid soap, under the hot tap, which is running hot, overflow rinse the glass 'til the overflow runs clear, then air dry the hot glass; I use a stainless cake rack to air dry glasses. For a perfectly clean and odour free glass, rinse with spring water prior to use: I guarantee this will work! Avoid putting a washing cloth or sponge in your glasses, ever!

Cheers and Good Luck.

I also air dry my glasses rather than wiping them. Maybe you inadvertently coated them with some grease from the cloth.
