Christmas deliveries and hours:  Last day to order to get your deliveries by Christmas for urban areas: North Island-Thurs 21st, South Island-Wed 20th.  Rural can take severa days longer.  Note these dates are aligned with delivery targets and are not guarantees.

We will be open over the Christmas break, but freight providers do not work on statutory holidays, so no deliveries will take place on statutory holidays.  We may not despatch orders containing yeast immediately to avoid yeast sitting on the network over a weekend or long weekend.

We will be answering support queries over the Christmas period within the 24 hour service standard.  However it may take longer than usual.

Hot weather and delivery timeframes:  With this very hot weather we are experiencing we may avoid sending items containing yeast over a weekend.  If relevant please include delivery instructions which avoid leaving orders including yeast sitting in the sun. Thanks for your understanding.

Merry Christmas!  Thanks for your business in 2017 and here's to a wonderful 2018.

Yeast needs a pH of about 2.5 to 5.5 to ferment.  So, if you are having difficulty getting your ferment started and/or your ferment has stuck or is sluggish it is a good idea to test the pH.

As you judge the result by comparing with the colour chart it won't give you a precise reading but these are an inexpensive way to indicate if your must is too acidic or not acidic enough.

Great to have on hand to do a quick test when your ferment is not behaving the way you hoped!

These are not specific to winemaking so can be used to test anything that you need a pH reading for eg soil, water, fish tanks, swimming pools etc
