Only put whisky into a decanter when some friends are around but was wondering how long does it keep ? Is it shorter than leaving a half empty bottle ? Kind regards. R L.

Personally I wouldn't store any whisky in a decanter for any length of time unless the stopper/lid provided a tight seal.

I suppose it depends on the air to whisky ratio in the bottle and the seal of the stopper, I wouldnt do it myself.

Right I try and make it a bit clearer and why! Friends come round so let's say half a bottle goes in and most of it goes, will it get last good for 24 hours or even until the next weekend so so 7 days.? Thanks again.

Right lads after asking this question a few weeks back I've another for you, I picked up what I think was a bargain for £3.50, it's a 70cl genuine wade porceline bells decanter with cork, it's A1 condition, now if I store some whisky in it will it keep longer than the glass decanters?? Kind regards.. RL.

I've no direct experience to draw on, but the obvious answer is that, assuming the porcelain is glazed, it shouldn't make a blind bit of difference. The point here is that the glazing on any ceramic is usually a thin layer of glass (plus any desired colouring and fluxing agents) fused onto the surface. It follows, then, that the material in contact with the whisky is, in fact, glass. Well, that's what I was taught in school, anyway. Maybe there's an expert on glazing here who knows the subject better than I do.

The Wikipedia article on ceramic glaze includes the following section:

Quote:
Composition

Glazes need to include a ceramic flux which functions by promoting partial liquefaction in the clay bodies and the other glaze materials. Fluxes lower the high melting point of the glass formers silica, and sometimes boron trioxide. These glass former may be included in the glaze materials, or may be drawn from the clay beneath.

Raw materials of ceramic glazes generally include silica, which will be the main glass former. Various metal oxides, such as sodium, potassium and calcium, act as a flux to lower the melting temperature. Alumina, often derived from clay, stiffens the molten glaze to prevent it from running off the piece. Colorants, such as iron oxide, copper carbonate or cobalt carbonate, and sometimes opacifiers such as tin oxide or zirconium oxide, are used to modify the visual appearance of the fired glaze.


This appears to bear out my thinking.

Whilst the porcelain will protect from light, it's probably still a good idea to keep it out of direct sunlight because that will still have a heating effect.

It is generally accepted that the glazed decanters tend to be more porous and unpredictable. While, if well made as mentioned above, it can be a perfectly good whisky vessel, it tends to be more of a lottery. And given you can't see through it, it's also harder to keep an eye on.

In the short term though, it should be just fine! A few months shouldn't make much difference at all. If any.

That makes logical sense. Ceramics inherently tend to be porous. The practical (i.e., non-decorative) function of glazing is to decrease the porosity. Any imperfection in the glaze, such as crazing, will expose the porous material behind it.

Whilst a glass decanter might be preferable, what you don't want is the tacky one that I got about thirty years ago. Every employee of the company (there were several thousand) was given one to celebrate 150 years of its existence. The decanter was obviously cheaply made, square in cross-section and had "Legal & General 1836-1986" emblazoned on one side. I never used it, and have no idea where it is now. It probably got mislaid in a house move. No loss.

Been scouring the charity shops again?

(It was you who said you'd got a pair of Glencairns dirt cheap that way, wasn't it?)

Store your scotch in glass, and buy an argon preserver like used for wine preservation. Spray a little argon in the container after serving -- just once, end of the night or the next day. This will allow your scotch to last unaltered for years.
