How to fine strain (double strain) cocktails

Words by Simon Difford & Kevin Armstrong

Most cocktails that are shaken and served 'straight-up' (without ice) benefit from an additional 'fine' or 'double' strain in addition to the standard strain to remove fine flecks of ice and small fragments of fruit that rise and float on the cocktail's surface. These spoil the appearance, detract from the mouthfeel and generally contaminate cocktails.

The quantity of ice fragments collected in the fine strainer from our pour can be as much as 8ml of water, which is equivalent to the best part of two barspoons of over-dilution.

Fine straining, or double straining, as it is sometimes known, became popular in London during the 1990s and has become standard procedure in the world's best bars. It involves holding a fine sieve, like a tea strainer, between the shaker and the glass. (This is not usually necessary when a cocktail has been stirred, thrown or rolled.)

Some, including Keven Armstrong of Saitan's Whiskers (see below), argue that this practice removes air trapped in the liquid, so affecting mouthfeel and reducing the thickness of any foam head. Rest assured, the holes in the strainer are small enough to capture ice crystals but not air.

Try shaking two cocktails in the same shaker and fine-straining one, not the other. The result is no perceivable difference other than ice shards and fruit fragments interfering with the mouthfeel of the unstrained cocktail. Try the above test again, this time with a cocktail containing egg white. Most of the foam passes through the fine strainer with no perceivable reduction in head gracing the fine-strained cocktail.

I will not defend the use of ridiculously small strainers with overly fine sieves, which appear to be used mostly by bars that make lots of muddled strawberry drinks. Yup, the poorly equipped fools will be there all night trying to push the last ounce of liquid through the clogged strainer.

I use Cocktail Kingdom's Coco Fine Strainers. These have ideal-sized mesh that is fine enough to collect ice and fruit particles but not so fine as to continually clog.

Sadly, some bars' fine strainers appear never to have been properly washed. Rinsing under running water between cocktails is adequate, with a more thorough clean in a glass or dishwasher at the end of each session/shift. (Glasswashers give a more gentle wash by design, and to make your stainless steel bar tools shine again, clean occasionally in a dishwasher on the intensive setting).

It is indisputable that fine straining improves the look of a shaken cocktail served straight-up, removing ice shards that would otherwise melt and contribute unwanted additional dilution. It also demonstrates the desire to try that little bit harder to produce perfect cocktails. The argument against revolves around the retention of microscopic air bubbles in the cocktail, and any shaken drink will 'clear' with time as air bubbles dissipate, whether fine-strained or not. However, for a balanced view, please consider Kevin's opinions below.

Why not to fine-strain by Kevin Armstrong in 2009

If you pass the words 'fine strained' through a fine strainer, you might be left with the letters FTAD, rearrange those and you get the word daft. My intention is not to trivialise this oft used technique as fine straining does indeed have its uses, although the proliferation of the technique would imply it is essential to good drinks making; this I'm afraid is just not true and I would argue it can work to the detriment of a drink.

When shaking a cocktail you do a number of things to it; you mix and chill the ingredients, add water through dilution but also, and most importantly, you inject a degree of 'life' or aeration. I believe it was once recommended that you ought to consume your drink whilst it is still 'laughing at you'; this 'life' or 'laughter', particularly in a shaken drink, is only captured within the first few moments, when the cocktail is poured. Passing a cocktail, such as a Daiquiri or a Cosmopolitan through a tightly meshed fine strainer removes this life before the drink has even reached the glass and it is with this that I hold umbrage.

Using a fine strainer changes the texture of a drink giving shaken drinks a more velvety feel, a texture often reserved for and associated with stirred cocktails. After 5 minutes in the glass, you'd never know if a fine strainer had been used or not but the difference in that magical first sip, as the bubbles dance on your tongue, is precious and worth savouring.

If a fine strainer is used to remove unwanted ice shards, I would argue an adequately deployed Hawthorn (perhaps with a second spring) would be sufficient, but the odd ice shard as it melts on the tongue can also be pleasant.

Aside from this, fine-straining every drink (as bartenders now seem to do) simply takes too much time and is often unhygienic as they are prepared to use just about anything (even keys!) to force their concoctions through the mesh. It is by all accounts an unnecessary affectation and should only be used to filter fruit seeds, pulp or detritus that cannot adequately be removed by standard strainers.

Also, not that it is a line I would like to pursue, but the lack of historical reference for the use of the fine strainer, also indicates that it is a modern stylistic artifice.

I recently witnessed a bartender fine strain a Gin Martini; can anybody tell me why? I think it's just a matter of time before we hear 'Can I fine strain your beer sir'?
