Storing spirit samples in Spirits & Cocktails Posted October 23, 2014 Thanks Hassouni - minis aren't a bad idea! I was thinking of asking Master of Malt if they use anything special, and / or are willing to sell their vials. They seem a friendly enough bunch. Actually, the main thing I want to sample is whisk(e)y, which I believe starts out on the acidic side - so possibly this is only a concern with PH neutral or alkaline spirits. Although I wonder if it can affect taste even if it doesn't affect the container. May have to do some experiments with PH strips.
