Diy Co2, Getting Mixtures To Start

[julioarca]

I am having troubles getting my CO2 mixtures to begin fermentation at the moment. During winter, radiators on, I make up a mix, 1 teaspoon yeast, 2 sugars, bicarb, small ammount warm water, mixed and put on radiator, 2 hours later a nice frothy mix.

However today, nice warm day, made mix, even put jug outside in the sun, no joy, there are some fumes coming off the mixture but no froth etc or bubble in it. This is noe after 7 hours. Yeast is prob 2 months old and kept in fridge, I wonder if this has become dud..

Anyway, how do you get your DIY yeast to kick start?

Thanks

Maybe something to do with your yeast..... what kind isit, i use Allisons active dry yeast in mine.

Here's how i mix mine......

Firstly i get a cereal bowl add 1 teaspoon of active yeast and then add half a bowl full of luke warm water, then stir. Leave this to settle until the end.

I then get a 2 1/2 litre bottle, add 2 cups of sugar, then fill the bottle quarter of the way up with luke warm water(shake bottle with hand over opening). I then pour the active yeast mixture into the bottle, and then finally fill the bottle to half way with warm water (i then shake the bottle again to mix it well). I hook it up and start to have bubble within 2 hours.

Other people do it differently but this works for me. Its all about trial and error really, experiment with the mixture.

I finally got a batch to work......some like warm water, 1/2 teaspoon yeast, bic of soda, pinch sugar....put jug on top of hot oven.....eventually it frothed and away it goes...then I added sugar and more luke warm water.....perhaps I will try your method Guppy_Man...thanx
