The science of cider

Sitting with an Aspall at 60 Million Postcards after a busy morning. With Mr B met an Italian acquaintance at Coffee Lab at 11. Then bus to Castlepoint B&Q for 2 G9 tiny LED Bulbs (what 2 for £16). Now relaxing with a science.

And so for steveng’s rather intellectual Wide Wednesday Challenge “Science- impact on our life”.

So am bringing it down to my level. How many of you check your glasses have nucleation points on the base to keep your drink bubbly (rather than flat). If you look closely at my blip, you will see the bubbles flowing up from the base. And if you don’t know what I’m talking about, read on:-

“The design of a pint glasses has a lot to do with how good a beer tastes as well.

Carefully curved lips and double-walled constructions improve the presentation and drinking experience of beer, but some brewers and manufacturers are taking the design a step further by etching marks or patterns onto the bottoms of their glasses to make the beer bubblier.

This practice is becoming increasingly more common - and perhaps you've had a drink out of one of these glasses without even knowing it.

These rough etchings are called nucleation points, and their job is to disturb the beer when it touches them. This gives the dissolved gas in the liquid something to latch on to and form bubbles, producing a steady stream of the bubbles as they rise from the base”.

And believe me, fizzy drinks are 100% bettter with them. Isn’t science wonderful!
