Sulphur levels are just as important as keeping your barrel full, it acts as a preserver along with alcohol and sugar. As your barrel breathes and ages, levels will drop. This will happen a lot quicker if there is more empty space inside the barrel.
S&K have sulphur tablets for you to put in your barrel to bring those levels up. We recommend that every 12-18 months to have the sulphur levels of your wine checked.
Stanton and Killeen provide a free testing service as part of our Barrel Club, we can analyse the level of sulfur and make recommendations for perfecting your blend. You can find the sample submission form here: Barrel Analysis form
ADDING SULPHUR TO YOUR BARREL
Simply add the recommended dose of sulphur to your barrel, it will fizz (similar to a Berocca tablet). Let it settle for approx 30 minutes.
