I like the 50cl size, it’s just right for lunch or for one at dinner.
There have been several posts here about the desirabiity of smaller bottle sizes.
The following from Springfield Estate then will be of interest.
The 500ml format also worked wonderfully for us in hotels and minibars …The biggest challenge with this size packaging is, unfortunately, the cost. While the contents cost proportionally less, the production costs remain the same regardless of bottle size. We tried to circumnavigate this by subsidising the packaging on the 500ml bottle, so that the price of the smaller bottle would be exactly two thirds of a full sized one.
However, the costs of the 500ml bottles have risen astronomically over the years, with the smaller bottle now actually costing five times more than a standard 750ml bottle. Our decision to subsidise the packaging has become unsustainable, and unfortunately this means that we have no choice but to discontinue the Life from Stone and Whole Berry in the 500ml bottles.
Sprinfgield Estate is listed by TWS for their wonderful ‘Life from Stone’ savvie - tho’ in 75cl bottle.
